American Airlines personal item size: what fits

Short answer: a American Airlines personal item must fit within 18 × 14 × 8 in. The Jelkin 25 is 25 × 17 × 14 cm (about 9.8 × 6.7 × 5.5 in); its longest side is well under American Airlines's longest allowed dimension of 18 in, and at 14 cm deep it clears any under-seat test, so it qualifies as a free under-seat item.

American is the most specific of the big US carriers: it publishes a size for both cabin pieces. The carry-on is 22 × 14 × 9 inches (56 × 36 × 23 cm) for the overhead bin, and the personal item is 18 × 14 × 8 inches (45.7 × 35.6 × 20.3 cm) for the space under the seat in front of you. Both are included on every fare, Basic Economy included.

American's two published numbers: 22 × 14 × 9 and 18 × 14 × 8 inches

Having both figures is useful, because it lets you test a bag rather than guess. The carry-on has to fit in the sizer, handles and wheels included. The personal item is meant to go under the seat, and American's published guidance is that it should fit there without being forced — a test that only works if you know which edge is which, which is what the guide to reading handbag dimensions is for.

American does not publish a carry-on weight limit for most of its network. A few international routes carry one — the number most often quoted for flights to and from mainland China is around 10 kg (22 lb) — so check the route if you fly long-haul.

Does 25 × 17 × 14 cm sit inside 45.7 × 35.6 × 20.3 cm?

Yes, with 2.5 in to spare on the tightest edge. Convert the bag first: 25 cm is 9.8 in, 17 cm is 6.7 in and 14 cm is 5.5 in. Sort both sets smallest to largest and compare: 5.5 in against 8 in leaves 2.5 in (6.4 cm) of slack on the depth; 6.7 in against 14 in leaves 7.3 in (18.5 cm) on the width; 9.8 in against 18 in leaves 8.2 in (20.8 cm) on the length.

The one thing to get right is the orientation. The bag's longest edge is 9.8 in, which is longer than the 8 in depth, so it has to lie with its length running along the 18 in axis — lengthwise along the seat, not across it. Do that and it drops straight in.

The 8-inch depth is the side people misjudge

Eight inches is about 20 cm of vertical space, which sounds generous, but a padded bag does not shrink much under pressure. The filling compresses by the equivalent of its own loft and then stops. This is also where a structured opening works against you in a sizer and for you everywhere else: it will not slump to 4 cm when you push it, but it does keep the bag standing upright so you can find things without emptying it.

What that means in practice: the bag's 5.5 in depth leaves 2.5 in of headroom, which is enough for a full load, but not for a hard sunglasses case strapped to the outside. Keep rigid items inside, flat against the base — the sunglasses case test shows how much room a hard case really takes.

Basic Economy boards last, and that is the real constraint

American includes both cabin pieces on Basic Economy, so the fare is not the problem. Boarding group is. Basic boards in the last group, and by then the bins above the first twenty rows are usually full, so your overhead piece ends up several rows behind you or gets gate-checked. The under-seat bag is the piece you are guaranteed to keep, so it carries documents, medication, charger, earbuds, a layer and the book. That split is the same one the airline personal item comparison recommends elsewhere.

American Eagle regional jets and the valet check

On American Eagle services flown by Embraer 145, CRJ-700 and CRJ-900 aircraft, overhead bins are small and carry-ons are collected at the aircraft door, tagged, and returned to you on the apron at arrival — free of charge. It is one of the more useful habits to build on a regional connection: keep the shoulder bag on you, hand over the wheeled case, and pick it up thirty seconds after you step off the aircraft. The Jelkin 25 Cloud Bag in biscuit is the piece that stays with you through the handover.

One packing adjustment before the gate

The usual failure is not the bag, it is the load. Two rigid objects pressed together — a sunglasses case and a power bank, say — push the front panel out by a centimetre or two. Lay them flat side by side along the base instead, put the soft items on top, and close the turn-lock before you measure. The guide to organising the inside of a soft bag covers the layout in more detail.

Allowances change with route, fare type, season and aircraft. The figures below were checked against the airline’s public baggage pages in October 2026 and are given as a guide only — always confirm on the airline’s own site before you fly, and measure your bag packed rather than empty.

Frequently asked questions

What is American's personal item size?

18 × 14 × 8 inches, which is 45.7 × 35.6 × 20.3 cm. A 25 × 17 × 14 cm bag clears it on every edge.

Does American Basic Economy include a carry-on?

Yes. Both the carry-on and the personal item are included on Basic Economy; you board in the last group.

How is the personal item measured?

By whether it fits in the under-seat space, not by a sizer in most cases. Keep rigid items flat so the front panel stays true.

Is there a weight limit for cabin bags?

Not on most routes. A few long-haul international routes publish one, most often quoted around 10 kg (22 lb) for mainland China.

Will a 13-inch laptop fit in a 25 cm bag?

No. The bag takes an iPad Mini, a paperback and a small camera, but a laptop has to travel in the overhead piece.

Check it against the others: the airline personal item size checker puts this allowance next to 18 other carriers and tells you whether a 25 × 17 × 14 cm bag passes.

Questions people ask

What is American Airlines' personal item size?

18 × 14 × 8 in. It must fit under the seat in front of you and is free in addition to your carry-on on qualifying fares.

Does a 25 × 17 × 14 cm (9.8 × 6.7 × 5.5 in) bag fit American Airlines?

Yes. The bag's longest side is about 9.8 in, shorter than American Airlines's longest allowed dimension, and at 14 cm deep it sits well under any under-seat test, so it drops in with room to spare.

Does the limit include handles and wheels?

Yes. American Airlines's personal-item figure is the outside of the bag including handles and wheels.
