Flying With a Baby on American Airlines

The short answer

American carries one lap infant under 2 free. A fully collapsible stroller under 20 lb may be carried on if it fits an overhead bin, otherwise it is gate-checked free. You can check one free bag for the infant, up to 25 lb and 22 x 14 x 9 in. Bassinets are on 777-200, 777-300 and 787 aircraft only, and not in First or Business.

The 20 lb stroller rule is the most useful line in US aviation

Most airlines say “compact strollers may be carried on” and leave you guessing. American states the condition: under 20 lb and it fits in an overhead bin (aa.com, read 2026-09-27). That gives you something to check a stroller against before you buy one.

Every compact travel stroller we compared is comfortably under 20 lb — the heaviest, the UPPAbaby MINU V3, is 16.7 lb. So on American the weight is rarely the problem; the bin fit is. Our carry-on stroller size guide puts folded dimensions against airline limits, and our overhead bin roundup lists the ones that genuinely fit.

The free infant bag nobody claims

American publishes a free checked bag for the infant, with an airport agent, not exceeding 25 lb and 22 x 14 x 9 in (aa.com, read 2026-09-27). That is 25 lb of checked capacity that exists whether or not anyone tells you about it at the counter. On a trip where you are paying for bags, it is worth asking about explicitly.

The newborn and older-child rules

Two more figures worth knowing before you book. American publishes that if your infant is under 7 days old you must contact Reservations, regardless of whether the flight is domestic or international — so a very new baby is not simply a booking you make online. And children 2 and older must have a purchased seat, which sounds obvious and catches out families whose child turns two mid-trip: the outbound leg may be a lap infant and the return may not.

The car seat rule follows from that. American publishes that one infant under 2 may travel in your lap and that you are not required to pay for a separate seat unless you have an FAA-approved car seat you plan to use on board — in which case the child needs a ticketed seat of their own. That is the same position the FAA takes: buying a ticket is the only way to guarantee you can use a restraint (faa.gov, read 2026-09-27). Our car seat on a plane guide works through the decision, and the lightest approved seats are in our travel car seat roundup.

Bassinets: two aircraft types, and not up front

American publishes that bassinets are first come, first served at the gate, for travel on 777-200, 777-300 and 787 aircraft only, and not available in First or Business cabins. Two consequences: check your aircraft type before you plan around a bassinet, and if you have paid for a premium cabin on a long-haul you may be the one without one. Our airplane bassinet guide compares this against Delta’s published limits.

Questions parents actually ask

Can I carry a stroller onto an American flight?

American publishes that you may carry on a fully collapsible stroller if it is under 20 lb and it fits in an overhead bin. Otherwise strollers should be checked at the gate before boarding and picked up at the gate after the flight, free of charge when traveling with a child.

Does American give an infant a free checked bag?

American publishes that you can check 1 bag free for the infant with an airport agent, not exceeding 25 lb (11 kg) and 22 x 14 x 9 in (56 x 36 x 23 cm). That is a real allowance most families never claim.

Does American have bassinets?

American publishes that bassinets are available on a first-come, first-served basis at the gate, for travel on 777-200, 777-300 and 787 aircraft only, and that bassinets are not available in First or Business cabins.

Is there an age minimum for a baby to fly on American?

American publishes that if your infant is under 7 days old you must contact Reservations, regardless of whether you are traveling domestically or internationally. Children 2 and older must have a purchased seat.

Do I need to buy a seat for a car seat on American?

Yes. American publishes that one infant under 2 may travel in your lap and you are not required to pay for a separate seat unless you have an FAA-approved car seat you plan to use on board — in which case the child needs a ticketed seat.
