Traveling with young children transforms even the simplest journey into a complex logistical operation. Between managing tickets, passports, snacks, and restless little ones, parents are constantly seeking solutions that streamline the experience. Enter the kids’ carry-on bag with an integrated ride-on seat—a seemingly ingenious invention that promises to solve multiple problems at once. Your child gets a fun ride through the airport while their essentials are neatly stored, and you avoid the bulk of an additional stroller. It’s no wonder these hybrid suitcases have become a fixture in terminals worldwide.
But beneath the colorful exteriors and clever marketing lies a critical question that too few parents ask: how safe are these bags when a real child is perched atop, hurtling through a crowded airport at speed? The unfortunate truth is that not all ride-on luggage is engineered with the same rigorous safety standards. While your child might treat it like a toy, it needs to perform like protective equipment during unexpected stops, sharp turns, or collisions. Understanding what safety testing actually matters—and demanding proof of it—separates a smart purchase from a dangerous gamble. Here are the five non-negotiable safety tests every parent must insist upon before clicking “add to cart.”
Understanding the Dual-Function Design Challenge
The fundamental engineering challenge of ride-on luggage lies in its split personality. It must simultaneously function as durable luggage—withstanding baggage handler abuse—and as safe transportation for a developing child. These competing demands create unique stress points that standard suitcases never encounter. The handle must bear vertical pulling force and horizontal pushing force while a child sits off-center. The wheels must roll smoothly when pulled but remain stable when bearing a dynamic, shifting load. The shell must protect contents while cushioning a passenger.
Manufacturers who treat these as simply “suitcases with seats” rather than “child mobility devices with storage” miss critical safety considerations. The best designs reverse this thinking, engineering first for child safety and second for luggage functionality. This mindset shift impacts everything from material selection to weight distribution, yet it’s invisible in product photos. Parents must dig deeper to understand which philosophy guided the design process.
Safety Test #1: Structural Integrity and Weight Capacity Verification
Static Load Testing Beyond the Stated Limit
Every ride-on bag lists a maximum weight capacity, typically ranging from 40 to 75 pounds. However, the stated number means nothing without understanding the testing methodology behind it. Demand evidence of static load testing where the bag was subjected to at least 1.5 times its stated capacity for a minimum of 24 hours without structural deformation. This safety margin accounts for real-world conditions like a child bouncing, leaning, or an adult accidentally pressing down on the seat.
The test should measure deflection in the seat area, handle attachment points, and wheel housing. Even minimal permanent bending indicates material fatigue that will compound over time. Ask manufacturers for the maximum deflection measurements under test loads—a reputable company will have precise data, not vague assurances. The seat platform should show less than 5mm of permanent deflection after testing to ensure it remains stable throughout the product’s lifespan.
Dynamic Stress Cycling Simulation
Static testing only tells half the story. The bag must also undergo dynamic stress cycling, where the loaded seat experiences thousands of simulated “bounces” and shifts. This replicates a child fidgeting, adjusting position, and the constant vibration from rolling over uneven surfaces. Insist on documentation showing the bag withstood at least 10,000 cycles at full weight capacity without cracking, loosening of fasteners, or developing play in the handle mechanism.
This test reveals hidden weaknesses in screw threads, plastic welds, and snap-fit components that static loading misses. A bag that passes this test will likely maintain structural integrity through years of travel, while failures here predict catastrophic mid-trip breakdowns that could injure your child and strand you without storage.
Safety Test #2: Multi-Directional Stability and Tipping Resistance
Center of Gravity Analysis in Real-World Scenarios
A child’s center of gravity sits much higher on a ride-on bag than the luggage contents would, creating a tipping risk that intensifies during turns, when leaning, or on inclines like jet bridges. Proper safety testing evaluates stability with a weighted dummy positioned at multiple points on the seat—center, forward, backward, and side edges. The bag should resist tipping on a 15-degree incline with weight distributed at any realistic sitting position.
Request the “tip angle threshold” test results. Quality manufacturers engineer their bags with a tip angle exceeding 30 degrees from center in any direction, achieved through a wide wheelbase, low seat height, and strategic weight distribution in the base. Anything less indicates a high risk of toppling when your child reaches for a dropped toy or turns to wave at someone.
Sudden Stop and Impact Stability
Airports require frequent sudden stops to avoid collisions or navigate queues. Your child’s ride-on bag must remain stable when you brake abruptly. The critical test simulates a loaded bag moving at 5 mph (average adult walking speed) coming to an instantaneous stop. During this test, the seat platform should not tilt more than 10 degrees, and the wheels must not buckle or splay outward.
This reveals weaknesses in wheel locking mechanisms and handle rigidity. Bags that fail this test send children tumbling forward onto hard terminal floors. Ask specifically about “deceleration stability testing” and whether the design includes anti-tipping geometry in the wheel housing or a reinforced handle stem that prevents flex-induced tipping.
Safety Test #3: Impact Absorption and Crash Simulation Protocols
Frontal Impact Protection Assessment
While no parent wants to imagine a collision, airports are dynamic environments with golf carts, cleaning equipment, and hurried passengers. Your child’s ride-on bag essentially functions as an unprotected vehicle. Demand evidence of frontal impact testing where a loaded bag strikes a solid barrier at speeds up to 3 mph (typical walking pace). The test should measure g-forces transmitted to the dummy’s torso and head.
Quality designs incorporate energy-absorbing materials in the front bumper and seat base, reducing impact forces by at least 30% compared to rigid structures. The seat should have a slight recline and wrap-around sides that prevent “submarining” (sliding forward) during impact. Without these features, even a minor collision can throw a child face-first into the ground or baggage.
Side Impact and Roll-Over Protection
Side impacts present different risks, particularly the potential for a child’s head to strike the floor during a tip-over. Proper testing includes a roll-over simulation where the loaded bag is tipped sideways from its stable position. The critical measurement is the height of the child’s head from the ground when seated—this “fall distance” should not exceed 12 inches to keep impact forces within safe limits for developing skulls.
Additionally, examine whether the handle design includes breakaway features or if it creates a puncture hazard during collapse. Handles that lock rigidly can become spear-like projections in a crash, while those with engineered failure points bend safely away from the child.
Safety Test #4: Comprehensive Material Safety and Toxicity Screening
Chemical Migration Testing for Child-Specific Exposure
Luggage materials undergo different safety scrutiny than children’s toys, yet a ride-on bag spends hours in direct contact with your child’s skin, mouth, and respiratory system. Standard luggage might pass adult-oriented tests while containing phthalates, heavy metals, or flame retardants that are unsafe for developing bodies. Demand compliance with both CPSIA (Consumer Product Safety Improvement Act) and European EN 71-3 standards for toy safety, which restrict far more substances than standard luggage regulations.
The critical test is “saliva and sweat migration analysis,” which measures how many chemicals leach out when a child chews on handle grips or rests their face against the seat during naps. This test should show zero detectable levels of BPA, phthalates, lead, and formaldehyde. Many manufacturers skip this expensive testing, assuming parents won’t ask. Make it your first question.
Abrasion and Flaking Resistance
Over time, constant use causes material breakdown. The safety concern isn’t just wear—it’s micro-particles that children inhale or ingest. Testing should include accelerated abrasion cycles that simulate a year of use, followed by analysis of particles generated. The surface coatings and plastics should not produce fine dust or flakes under normal friction.
This is particularly crucial for painted designs or textured grips that can degrade into microscopic particles. Ask for the “abrasion particle generation test” results and ensure the bag uses integral color (color molded into the plastic) rather than surface paint that can chip away.
Safety Test #5: Dynamic Wheel and Handle Durability Under Real Loads
Wheel Assembly Fatigue Testing
Wheels on ride-on bags fail catastrophically because they experience forces never intended for luggage—lateral stress from turning under load, vertical impact from curbs, and constant vibration. The safety test simulates 50 kilometers of travel on a textured surface while loaded to capacity, including periodic curb drops and sharp turns. After testing, wheels should show less than 2mm of play in their axles and no cracking in the wheel material.
Inspect the test parameters carefully. Some manufacturers test wheels unloaded or on smooth surfaces only. Real-world testing includes carpet, tile, concrete, and transitions between surfaces. The wheels should be made from injection-molded polyurethane with sealed bearings, not cheap PVC that cracks or develops flat spots that create instability.
Handle Stem Resilience and Locking Mechanism Reliability
The handle stem endures complex stress patterns—it pulls, pushes, steers, and supports a leaning child. Testing must evaluate not just tensile strength but also resistance to bending fatigue and torsional stress. Demand documentation of at least 5,000 full extension/retraction cycles with a side load applied to simulate a child leaning. The locking mechanism must engage positively every time without slipping.
A critical but often overlooked test is “handle twist resistance” under load. A child shifting their weight can twist the handle, causing the bag to veer unexpectedly. The handle assembly should resist more than 15 Newton-meters of torque without deforming or unlocking. Weak handles create unpredictable steering that can send the bag into obstacles or other travelers.
How to Verify Manufacturer Safety Claims Without a Engineering Degree
Decoding Marketing Language vs. Certified Testing
Manufacturers excel at using impressive-sounding phrases like “rigorously tested” or “safety certified” without providing actual data. Your first step is requesting specific test reports, not summary statements. A legitimate company provides documents from accredited labs (look for ISO 17025 accreditation) showing test methods, parameters, and quantitative results. Vague claims about “exceeding industry standards” are meaningless when no specific standards exist for this product category.
Create a verification checklist: Does the report name the testing laboratory? Are test dates within the last two years? Do the test methods match the stresses your child will actually create? Are results expressed in measurable units (Newtons, millimeters, g-forces) rather than subjective ratings? If a company cannot produce these documents, their testing claims are likely marketing fiction.
Red Flags in Product Listings and Manuals
Certain phrases should trigger immediate skepticism. “Tested for durability” without specifying how, “meets all safety requirements” without naming which ones, or “as safe as a stroller” without stroller-specific testing are all warning signs. Also beware of weight limits that seem too high for the bag’s size—this often indicates the company tested the empty bag’s material strength, not its stability with a real child.
Examine the product manual before purchasing. Quality manufacturers include detailed safety instructions, explicit weight and age limits, maintenance schedules, and warnings about specific hazards. If the manual is a single page of generic statements, the company hasn’t invested in serious safety engineering. The presence of a dedicated safety section with technical specifications suggests a more rigorous development process.
The Critical Role of Third-Party Certification Bodies
Recognized Testing Organizations for Child Mobility Products
Unlike car seats or strollers, ride-on luggage lacks a mandatory federal safety standard in most countries. This regulatory vacuum makes voluntary third-party certification essential. Look for testing by SGS, TÜV Rheinland, Bureau Veritas, or Intertek—organizations with specific protocols for children’s products, not just general luggage testing. Certification from these bodies means the product underwent testing the manufacturer couldn’t control or modify.
Specifically, inquire about certification to ASTM F833 (standard for strollers) even though these aren’t strollers. Manufacturers who voluntarily submit to stroller standards demonstrate confidence in their product’s safety margins. Also valuable is certification to EN 1888 (European stroller standard) or ISO 7175 (international crib standard) for impact and material safety. These certifications are expensive and time-consuming, so companies that pursue them prioritize safety over rapid market entry.
Understanding the Limitations of Current Standards
No perfect standard exists for ride-on luggage, which creates a “standard shopping” problem where manufacturers seek the easiest certification to obtain. Be wary of claims based solely on CPSC general conformity certificates, which require no actual testing for most luggage categories. These documents are self-reported and don’t involve third-party verification.
The most honest manufacturers will admit their product occupies a regulatory gray area and provide testing data across multiple standards to cover different risk aspects. They might show stroller standards for stability, toy standards for materials, and luggage standards for durability. This patchwork approach, while imperfect, demonstrates comprehensive safety thinking. Avoid companies that rely on a single, loosely applicable certification as a blanket safety claim.
Age and Weight Guidelines: Why They Exist Beyond Liability Protection
Developmental Factors Affecting Safe Use
Weight limits address structural concerns, but age recommendations reflect developmental readiness. Children under three lack the core strength and reaction time to ride safely, even if they meet weight requirements. Their proportionally large heads raise their center of gravity dangerously high, and their instinctive protective reactions during falls are immature. Most safety engineers recommend a minimum age of three years, regardless of the stated weight limit.
Conversely, older children (over six) may exceed weight limits but still want to ride due to fatigue. Their longer legs create different stability issues, and their heavier weight increases stopping distances and turning radius. The ideal user is 3-5 years old, within the weight limit, and developmentally capable of following safety instructions. Using the bag outside these parameters compromises both safety and functionality.
The Dangers of “Just This Once” Overloading
Every parent has been tempted to let a slightly-too-heavy child ride “just this once” during a long layover. This seemingly minor decision dramatically increases failure risk. Engineering safety margins are calculated precisely—exceeding the limit by even 10% reduces the tip resistance angle by several degrees and increases stress on wheel axles by over 20%. These margins compound across multiple stress factors: a slightly overloaded bag, a tired child leaning oddly, and a quick turn can combine to create a failure that wouldn’t occur with any single factor alone.
The weight limit also assumes proper load distribution inside the bag. Overloading the storage compartment while staying under the seat weight limit creates a different hazard—raised center of gravity. The total weight (child + contents) matters less than where that weight sits. A 40-pound child with 10 pounds of low-packed luggage can be safer than a 30-pound child with 15 pounds of high-stacked items. Teach children to sit still and keep the heaviest items at the bottom of the bag.
Airport-Specific Safety Considerations Most Parents Overlook
Navigating Security Checkpoints Safely
The Transportation Security Administration (TSA) and international equivalents require all items to go through X-ray screening, which means your child cannot ride through the metal detector. This creates a hazardous transition period where the bag becomes ordinary luggage in a high-traffic area. The safest approach is to unload your child well before the checkpoint and immediately collapse or secure the handle to prevent it from becoming a tripping hazard for other passengers.
Some airports prohibit ride-on luggage in security lines entirely, requiring it to be treated as a checked item. Check your departure airport’s policy before travel. The bag’s wheels can trap small fingers when loading onto conveyor belts, so teach children never to touch the bag once it’s placed for screening. The handle locking mechanism should be robust enough to survive the belt journey without extending unexpectedly.
Gate-Checking and Aircraft Storage Hazards
When overhead bin space runs out, flight attendants may gate-check your ride-on bag. This transitions it from child carrier to cargo, where it will be thrown into the hold without consideration for its delicate mechanisms. Insist on a protective cover or bag that shields the handle and wheels during this process. More importantly, verify that the design includes internal reinforcements that protect the seat area from collapse under stacked luggage.
The pressure changes and temperature fluctuations in cargo holds can affect plastic components and lubricants. Ask manufacturers specifically about “cargo hold conditioning” testing that simulates these environments. Bags that become brittle at altitude or develop sticky handle mechanisms from pressure changes pose post-flight safety risks. After gate-checking, always re-inspect the bag before letting your child ride again.
Maintenance and Ongoing Safety Checks Every Trip Requires
Pre-Flight Inspection Protocol
Before each journey, conduct a 5-minute safety inspection. Check wheel axles for play by grasping each wheel and attempting to wiggle it side-to-side. Any movement beyond 2mm indicates bearing wear that could cause sudden wheel failure. Extend and lock the handle, then apply firm downward pressure to verify the lock holds without slipping. Test the seat platform by pressing firmly on each corner—any cracking sounds or excessive flex mean immediate retirement.
Examine all screw heads and fasteners. Vibration from rolling loosens them over time, creating wobble that compounds into structural failure. Use a small screwdriver to verify tightness, but avoid over-tightening, which can strip plastic threads. Check the seat surface for cracks, especially around stress concentration points like corners and handle attachment areas. Even hairline cracks propagate rapidly under dynamic loads.
Recognizing When Retirement Is Mandatory
Ride-on bags have shorter safe lifespans than regular luggage due to the stresses of carrying children. Retire any bag immediately after a significant impact, such as falling down stairs or being dropped from a height while loaded. Hidden micro-fractures in the plastic render the structure unsafe even if visible damage seems minor.
Also establish a retirement schedule based on usage frequency. A bag used weekly for airport travel should be replaced every 18-24 months, while occasional travelers can extend to 3 years. Materials fatigue from UV exposure, temperature cycling, and repeated stress, even without visible wear. If the bag feels “wobbly” or the handle develops play that tightening won’t fix, the internal components have fatigued and failure is imminent. Don’t gift used ride-on bags to other families—unseen damage passes with it.
Teaching Your Child to Be an Active Participant in Safety
Establishing Non-Negotiable Riding Rules
Even the safest bag becomes dangerous with an unpredictable rider. Establish three absolute rules before the first ride: sit centered, keep both feet on the footrests, and never stand up while moving. Practice these rules in a safe, open area before navigating crowds. Use a rewards system for safe riding, but enforce immediate removal from the bag for violations—consistency matters more than convenience.
Teach children to assume a protective position during stops: lean slightly back with hands gripping the handle sides, not the top. This prevents forward pitching if you brake suddenly. Practice “emergency stops” at home so your child learns to expect and react to abrupt halts. The goal is developing muscle memory that protects them when real emergencies occur.
Supervision Strategies That Actually Work
The biggest safety mistake parents make is treating the ride-on bag as a babysitting tool. Effective supervision means staying within arm’s reach at all times, maintaining constant visual contact, and never using the bag in crowded areas where sudden stops are likely. Keep one hand on the handle at all times, even when the child is seated securely—this prevents tip-overs and gives you immediate control.
Avoid using smartphones while your child rides; the distraction eliminates your reaction time. In crowded terminals, consider having your child walk while you pull the empty bag, then ride only in open concourses. The safest riding zone is the moving walkway, where speed is constant and direction is linear, but even here, maintain physical contact with the bag.
The Legal and Regulatory Reality: What Protects Your Child
Current Regulatory Gaps and Why They Matter
Ride-on luggage exists in a regulatory no-man’s land. The CPSC classifies them as luggage, which faces minimal mandatory testing. The FAA focuses on aircraft safety, not passenger equipment used in terminals. No federal standard requires child-specific safety testing for these products. This means manufacturers self-police, and safety claims are largely unverified until after injuries occur and lawsuits force recalls.
This regulatory vacuum places full responsibility on parents to vet products. Unlike car seats, which must pass FMVSS 213 certification to be sold, ride-on bags can reach market with no third-party child safety validation. Some manufacturers exploit this by copying designs without understanding the engineering, leading to batches of visually identical but structurally inferior products. Always verify the manufacturing date and whether design changes occurred after initial production—a common source of unexpected failures.
Staying Informed About Recalls and Incident Reports
Because no central database tracks ride-on luggage incidents, parents must proactively search for safety information. Set up Google Alerts for the generic product category plus terms like “recall,” “injury,” and “safety warning.” Monitor the CPSC’s recall database weekly, and check international sources like the EU’s Safety Gate and Health Canada’s recall listings, as many products sell globally.
Join parenting travel forums and search for real-world failure stories. While anecdotal, patterns emerge quickly—multiple reports of handle collapse or wheel failure from the same brand indicate systematic design flaws. Document any safety concerns you experience, no matter how minor, and report them to the manufacturer and CPSC. Your report could trigger an investigation that protects other children.
Making Your Final Decision: The Safety-First Evaluation Framework
The Pre-Purchase Documentation Checklist
Before purchasing, you should be able to obtain and review: (1) Complete structural test reports from an ISO 17025 accredited lab, (2) Material safety data sheets confirming CPSIA and EN 71-3 compliance, (3) Stability test results with specific tip angles and load positions, (4) Wheel and handle fatigue test summaries, and (5) A clear statement of design philosophy prioritizing child safety. If any document is unavailable or redacted, walk away.
Create a weighted scoring system: structural integrity (30%), stability (25%), material safety (20%), durability testing (15%), and transparency of safety claims (10%). This framework prevents being swayed by attractive designs or clever features that don’t enhance safety. A boring-looking bag that passes all tests is infinitely safer than a stylish one with incomplete safety documentation.
Post-Purchase Verification Steps
After purchase, verify safety before your child’s first ride. Weigh the bag on a bathroom scale with your child seated to confirm you’re within limits. Measure the seat height from the ground—if it exceeds 12 inches, the fall risk is higher than optimal. Perform your own stability test by loading it with weights and gently attempting to tip it in different directions. If it feels tippy in your living room, it will be dangerous in a busy airport.
Finally, register the product with the manufacturer. This ensures you’ll receive recall notifications and validates your warranty. Keep all documentation, including your purchase receipt and any correspondence with the company about safety questions. In the unfortunate event of a failure, this paper trail proves you exercised due diligence and strengthens any potential claim.
Frequently Asked Questions
What age should my child be before using a ride-on carry-on bag?
Most safety engineers recommend a minimum age of three years old. By this age, children typically have the core strength, balance, and impulse control to ride safely. More importantly, they can understand and follow basic safety instructions. Children under three have proportionally larger heads relative to their bodies, raising their center of gravity and making falls more dangerous. Always consider developmental readiness over age—if your child cannot sit still for 10 minutes or follow simple commands, they’re not ready regardless of age.
How do I know the true maximum safe weight limit?
Trust only weight limits backed by documented static and dynamic testing. The number should be stamped on a permanent label, not just listed on packaging. Verify that testing included at least 1.5 times the stated limit for 24 hours without deformation. Be conservative—if your child is within 5 pounds of the limit, consider a larger capacity bag. Remember that the limit includes both child weight and luggage contents, so factor in your typical packing load when calculating safety margins.
Are ride-on carry-on bags allowed on all airlines?
No universal policy exists. Most airlines permit them as carry-on if they fit size restrictions (typically 22" x 14" x 9"), but some prohibit riding in the terminal due to liability concerns. Southwest and several European low-cost carriers have specific bans on riding. Always check your airline’s “special items” policy before travel. Gate agents have discretion to prohibit riding if they deem it unsafe, so have a backup plan for transporting a tired child if needed.
What should I do if the bag breaks or feels unstable during travel?
Immediately stop using it for riding and convert it to standard luggage. If structural failure occurs, photograph the damage, keep all broken parts, and file a report with the airport’s customer service desk to create an official incident record. Contact the manufacturer within 24 hours with your documentation. Do not attempt temporary repairs with tape or zip ties—the safety margin is already compromised. For the remainder of your trip, rent a stroller or carrier; most airports have rental services in terminals.
How can I verify a bag has proper safety certification?
Look for certification marks from SGS, TÜV Rheinland, Bureau Veritas, or Intertek on the product label. Request the actual certificate number and verify it on the certifying body’s website. Be wary of vague “meets ASTM standards” claims without specific standard numbers. True certification includes a unique identifier you can trace. Also check for a Children’s Product Certificate (CPC) for U.S. sales, which is legally required but often ignored by importers of ride-on luggage.
Can a ride-on bag replace a stroller for airport travel?
Only for children within the optimal age range (3-5 years) and weight limit who no longer need stroller support for napping. Ride-on bags lack stroller restraints, sun protection, and reclining seats, making them unsuitable for infants or long travel days. They excel for active preschoolers who need occasional rest but walk most of the time. For younger children or full-day travel, consider a compact travel stroller plus a regular carry-on. The ride-on bag is a supplement, not a replacement, for proper child transport equipment.
What are the biggest safety red flags when shopping?
Extremely low price points (under $60) often indicate corner-cutting on materials and testing. Vague safety claims without specific test names or numbers are major warnings. Bags where the seat sits higher than 12 inches from the ground increase fall risk significantly. Poorly translated manuals suggest the company lacks U.S. safety expertise. Finally, avoid bags with exposed screw heads on the seat surface—these create pressure points and injury risks during falls. Any one of these issues should disqualify a product from consideration.
How often should I perform safety inspections?
Conduct a quick pre-trip inspection before each journey, checking wheels, handle lock, and visible cracks. Perform a detailed monthly inspection if you travel weekly, including checking fastener tightness and testing stability on an incline. After any incident where the bag falls or is dropped from height, perform immediate retirement evaluation. The handle locking mechanism deserves weekly testing with frequent use, as this is the most common failure point. Keep a small toolkit in your luggage for on-the-road repairs to fasteners.
Do more expensive ride-on bags guarantee better safety?
Price correlates with safety up to about $150, beyond which you’re often paying for branding or licensed characters. The $80-$150 range typically includes proper testing and quality materials. However, some premium brands charge more for aesthetics without superior engineering. Focus on documentation over price—a mid-range bag with transparent test reports beats an expensive one with vague claims. Be suspicious of bags under $60, as proper child-specific testing costs more than that to conduct. Price should support safety investment, not marketing.
What if my child refuses to follow safety rules while riding?
Immediate and consistent consequences are essential. Remove the child from the bag at the first rule violation and have them walk for a set period (e.g., 10 minutes). Explain clearly why the rule exists—“If you stand up while moving, you could fall and hit your head”—so they understand it’s about safety, not control. For persistent rule-breaking, retire the riding feature for the remainder of the trip. A child who cannot ride safely endangers themselves and others. It’s better to deal with a disappointed child than a medical emergency in a foreign airport.'
