Lap infants are legal on U.S. flights, but the safety argument against the practice is decades old. United Flight 232 crashed with a toddler named Evan Tsao flying on his mother’s lap — no seat, no restraint.
His death drove NTSB Recommendation A-90-78, which told the FAA to require approved restraints for children under 40 pounds and 40 inches. The FAA has never adopted it, arguing that pushing families onto highways would kill more people than child restraints would save.

Most people assume the rules changed after a toddler died. They didn’t. Everyone remembers the crash; fewer remember what the regulator did afterward — which was mostly to run the numbers.
On July 19, 1989, United Flight 232 suffered a catastrophic engine failure, and the crew fought the crippled DC-10 toward an emergency landing at Sioux Gateway Airport. It broke apart while attempting to land. Of the 296 people aboard, 112 died.
One of them was Evan Tsao. He was 22 months old, riding on his mother’s lap in coach, and when the fuselage came apart he was separated from her.
The NTSB later recorded his cause of death as smoke inhalation. Evan’s death became the one that turned the cabin instruction into a formal fight, and it sat at the center of the NTSB’s push for child-restraint rules. Three decades later, the legal exception that put him on that lap is still on the books.
The crash that turned a policy question into a person
Nothing in the rulebook required Evan Tsao to have a seat. The era’s standard emergency instruction told parents to put babies on the floor and brace them.
Jan Brown, the lead flight attendant on Flight 232, pushed back publicly afterward. She argued the guidance had failed children exactly like Evan. Her criticism fed directly into what became NTSB Safety Recommendation A-90-78.
The NTSB asked for a mandate in 1990 — the FAA still hasn’t delivered
On May 30, 1990, the NTSB issued Safety Recommendation A-90-78. The recommendation asked the FAA to redraft the rules governing Parts 91, 121, and 135, requiring every occupant to be restrained for takeoff, landing, and turbulence. Infants and small children under 40 pounds and 40 inches, the Board wrote, should ride in an approved restraint suited to their size.
That language survives in the NTSB’s public records today. It has never become a federal requirement. What followed instead was an argument about money, highways, and whose risk counts.

The diversion math that keeps lap infants legal
Cost, not just safety, has driven the FAA’s refusal. Its 1995 report to Congress set out what a child-restraint mandate would actually change.
The base case found restraints would prevent at most five child crash deaths per decade. But it also estimated the rule would add roughly 82 deaths, net, over the same period — because some families, told they needed an extra ticket, would drive instead of fly.
The NTSB has disputed that math, and pediatric groups have joined it. The FAA still reaches for the same diversion figure each time it reviews the rules — and each time declines to require child seats. A 2003 study in JAMA Pediatrics helps explain why the stakes feel so abstract: deaths of babies and toddlers on U.S. commercial aircraft average less than one a year.
That’s a real number, but it means the diversion argument is almost impossible to beat with crash statistics alone.
Other regulators accept lap infants — but draw different lines
The U.S. isn’t alone in allowing lap infants. What separates it is how little else it requires.
The International Civil Aviation Organization holds that the best protection for a young child is a State-approved restraint in a dedicated seat, but it leaves any mandate to individual states. Most countries, including Canada, still don’t require age- and size-appropriate restraints at any point in the flight.
The sharpest contrast involves the loop belt, a device that secures an infant to an adult’s belt. New Zealand’s rules set that as the mandatory floor, while the United States expressly forbids it. Transport Canada has allowed child restraints since 1990 and now recommends them for all phases of flight.
Australia requires lap infants to be restrained and bars wrapping the adult belt around both people.
The table below shows how six regulators approach the same question.
| Jurisdiction/regulator | Are lap infants permitted? | Is an approved child restraint required or recommended? | Key regulation or advisory reference |
|---|---|---|---|
| United States (FAA) | Yes — children under two may be held on an adult’s lap. | FAA recommends approved restraints but does not require them; belly belts are prohibited. | 14 CFR 121.311; FAA guidance. |
| Canada (Transport Canada) | Yes — infants under two may be held in an adult’s arms. | Child restraints are permitted and strongly recommended for all phases of flight. | AC 605-004; AC 700-036. |
| European Union / EASA | Yes — EU-OPS allows infants on an adult’s lap with loop belts. | Approved child restraints are recommended; lap belts aren’t considered protective in a crash. | EU-OPS; EASA Study on Child Restraint Systems. |
| Australia (CASA) | Yes — lap-held infants are allowed on Australian-registered aircraft. | Lap infants must be restrained; the adult belt cannot wrap around both people. | CASA AC 91-18. |
| New Zealand (CAA) | Yes — infants up to two may sit on a parent’s lap with loop belts. | A supplementary loop belt is the minimum; approved restraints are an alternative. | Part 91, Appendix A; CAA guidance. |
| ICAO (Doc 10049) | ICAO doesn’t mandate lap infants; many states allow them. | Safest option is a State-approved CRS in a dedicated seat; states decide mandates. | ICAO Doc 10049 and related guidance. |

Where the rule actually lives
The lap-infant exception sits inside 14 CFR 121.311, titled “Seats, safety belts, and shoulder harnesses.” Under Part 121, the rule lets an adult sitting in an approved seat hold a child younger than two. That’s the entire legal basis for the lap child.
The same section draws a second, stranger line: during taxi, takeoff, landing, and surface movement, a belly belt or similar lap-held device is not approved for use. In other words, the adult may hold the infant, but attaching the infant to the adult with anything resembling a restraint is forbidden in the highest-risk phases. It is a permissive rule with a prohibition buried inside it.
It also explains why cabin crews, whatever their own view, can’t simply insist on a seat for an under-two: the regulation defines the child’s place as the adult’s lap.
What this means if you’re flying with a child under two
You have three options, and only one matches what the FAA’s own guidance says is safest: an approved restraint in the child’s own seat. The alternatives are to hold the child on your lap — legal, but the agency warns that your arms can’t hold a child securely in unexpected turbulence, the leading cause of pediatric injuries in the cabin — or to check the car seat and fly lap-held, saving the fare but giving up any restraint protection.
On most U.S. carriers, a lap child flies free on domestic routes; on international ones, the fare is a percentage of the adult’s. There is no child-specific discount: if the child occupies a seat, the airline charges for that seat. The cost conversation, in other words, is less about a safety discount and more about whether an extra ticket is worth the protection it buys.
Key terms
- Lap infant
- A lap infant is a child under two years old who flies without a purchased seat, held by an adult buckled into an approved seat. U.S. rules permit the arrangement under Part 121, and Transport Canada uses the same under-two threshold even as it recommends an approved restraint for every phase of flight. What no regulator publishes is a count: neither the FAA nor the NTSB keeps a dataset tracking how many lap infants have been hurt or killed on U.S. commercial flights, so the case for change rests on estimates rather than a tally.
- 14 CFR 121.311
- 14 CFR 121.311, titled “Seats, safety belts, and shoulder harnesses,” is the federal rule that governs how passengers are secured on U.S. airline flights. It sits in Part 121, the FAA’s operating rules for scheduled carriers, and it allows an adult in an approved seat to hold a child younger than two rather than buy a separate ticket. The NTSB’s 1990 recommendation would have pushed restraint requirements across Parts 91, 121, and 135, well beyond the airline operations this one section covers.
- Loop belt
- A loop belt, also called a belly belt, is a supplementary strap that loops around an infant and attaches to the adult’s seat belt, tethering the child to the parent during flight. New Zealand’s Civil Aviation Rules set it as the minimum standard for infants and EU-OPS rules permit it, even though EASA’s own study concluded it should not be treated as crash protection. Only the U.S. position makes it a forbidden device rather than a fallback: the same strap that is a mandated floor in New Zealand cannot legally be used on a U.S. carrier.
- Child restraint system
- A child restraint system is an approved seat or harness built to hold an infant or small child in place during flight rather than leaving the child in an adult’s arms. Regulators each publish their own list of acceptable standards — New Zealand’s CAA, for one, accepts devices meeting TSO C100, New Zealand Standard 5411, AS/NZS 1754, FMVSS 213, or ECE 44. Where airlines have stayed out of it is the commercial side: no public record tracks how many carriers discount a seat to encourage CRS use, and the evidence points to sporadic offers rather than a settled practice.
Questions? Answers.
Is it safe to have a lap child on a plane?
No — FAA guidance says an approved child restraint is the safest place for a young child, not a lap, and notes that a parent’s arms cannot hold a child securely in unexpected turbulence, the leading source of pediatric injuries on a plane.
What are the FAA rules regarding child safety in aircraft?
Under 14 CFR 121.311, an adult in an approved seat may hold a child under two, but lap-held devices such as belly belts are not approved during taxi, takeoff, or landing.
Can my 5 year old sit on my lap on a plane?
No — the in-lap exception applies only to children younger than two, so a five-year-old must occupy a seat.
Do kids fly free if they sit on your lap?
On most U.S. airlines, a lap child occupying no purchased seat rides without a seat fare, but there is no child-specific discount: airlines charge for the seat regardless of who occupies it.
