You can’t wear your baby in a carrier during takeoff and landing because federal aviation rules require every passenger to be secured with a separate seatbelt or held on a lap, and baby carriers fall into a category of devices the FAA has specifically banned for those phases of flight. The restriction isn’t arbitrary. Crash testing showed that carrier-style devices can crush a baby against the seat in front of you during a sudden deceleration.
What the FAA Rule Actually Says
Federal Aviation Regulation 121.311 states that during takeoff and landing, every person on board must occupy an approved seat with a separate safety belt. There is one exception: a child under two years old may be held on an adult’s lap. That’s it. A baby carrier, wrap, or sling doesn’t qualify as an approved restraint, and wearing one doesn’t count as holding your child on your lap.
The FAA explicitly prohibits three types of child devices during ground movement, takeoff, and landing: belly belts (which loop a child’s restraint through the adult’s seatbelt), vest- and harness-type devices that attach the child to the parent or to the aircraft seatbelt, and booster seats. Baby carriers and slings fall squarely into the harness/vest category. They’re banned not because of a bureaucratic technicality but because of what happens to them in crash simulations.
What Crash Testing Revealed
The FAA’s Civil Aerospace Medical Institute (CAMI) ran dynamic crash tests on these devices using child-sized test dummies, and the results were alarming.
For belly belt devices, which strap a baby to the adult’s seatbelt, the test showed a chain reaction: the adult’s torso flings forward, the child’s body slams into the seat back in front of them, and then the adult’s chest strikes the child from behind, crushing the baby between the adult and the forward seat. The forces involved are enormous, even at survivable crash speeds.
Harness-type restraints performed poorly in a different way. The child dummy slid forward and off the seat entirely, with its whole body impacting the seat in front. Then the elasticity in the harness webbing snapped the dummy backward, creating a second wave of injury risk from the rebound. A soft baby carrier or wrap would behave similarly or worse, since it lacks even the structural webbing these tested devices had.
The core physics problem is simple: in a sudden stop, your body keeps moving forward with tremendous force. Anything strapped to your chest moves with you, and your body weight becomes the thing that injures your child. Holding a baby on your lap isn’t ideal either, but it at least allows the child to move somewhat independently rather than being pinned between you and a hard surface.
Why Takeoff and Landing Specifically
Takeoff and landing are the highest-risk moments of any flight. The plane is close to the ground, moving at high speed, and has the least room to recover from mechanical failures or other emergencies. The vast majority of aircraft accidents occur during these phases. That’s why seatbelt rules, tray table requirements, and seat position rules all kick in at the same time.
During cruise, the risk profile changes. Turbulence is the main concern, and while it can be violent, the forces involved are typically much lower than a crash-speed deceleration. Most airlines will let you wear your baby in a carrier once the seatbelt sign is off at cruising altitude, though policies vary by airline. Some flight attendants may ask you to remove the carrier even during turbulence, which is at their discretion.
What You Can Do Instead
For takeoff and landing, you have two options. The first is simply holding your child on your lap with your seatbelt fastened around yourself only, not around both of you. This is what most parents of children under two do, and it’s permitted by federal regulation. The seatbelt goes around you alone. Never loop the seatbelt around yourself and the baby together, as this creates the same crushing risk the crash tests identified.
The second, safer option is buying a separate seat for your child and using an approved child restraint system. These are typically car seats that meet Federal Motor Vehicle Safety Standard 213 and carry a label saying they’re certified for use in both motor vehicles and aircraft. There are also aviation-only restraint devices (the FAA calls them ACSDs) designed specifically for airplane seats. These have been tested under aviation-specific crash conditions and passed.
The FAA doesn’t require you to buy a separate seat for a child under two, but it strongly encourages it. An infant in an approved car seat secured to its own airplane seat is significantly safer than a lap-held child in any scenario, whether that’s a crash, a hard landing, or severe turbulence. The tradeoff is cost, since you’ll need to purchase a full-price ticket for the seat.
What to Expect at the Gate and On Board
You can wear your baby through the airport and down the jet bridge with no issue. The carrier only needs to come off before the plane pushes back from the gate. Flight attendants will typically remind you during the pre-departure safety check. Plan to have the carrier accessible so you can put it back on once you reach cruising altitude if you’d like.
If you’re traveling with a car seat and a separate ticket for your child, bring the seat to the gate. Most rear-facing and convertible car seats fit in airplane seats, though some bulkier models can be tight. Check that yours has the FAA approval label before you fly. If the seat doesn’t fit or isn’t labeled, the crew can reject it and you’ll be holding your child on your lap instead.
