To avoid any surprises or unpleasant experience at the airport, it is best to stick to American Airlines carry-on size limits by checking your bag’s dimensions before heading to the airport.

Let’s break it down.

What Is American Airlines Carry-On Size Policy?

American Airlines has a standard carry-on size limit: 22 x 14 x 9 inches (56 x 36 x 23 cm), including handles and wheels.

This applies to most flights, except for some smaller planes with limited overhead bin space.

Now, do they place every single bag in the size ?

Not always.

But if they do, your bag must fit in the sizer, which actually measures around 22.25 x 14 x 10 inches 56.52 × 35.56 × 25.4 cm.

If it doesn’t fit, you may have to check it.

In addition to your carry-on, you’re allowed one personal item like a small backpack, purse, or laptop bag that must fit under the seat in front of you.

The maximum size is 18 x 14 x 8 inches (45 x 35 x 20 cm).

If you’re flying Basic Economy, you’re only allowed one personal item unless you’re an AAdvantage elite member, an eligible AAdvantage credit cardholder, or a Oneworld elite member.

If you try to bring a full sized carry-on to the gate, you’ll have to pay $35 to check it, plus a $25 gate handling fee.

What About Smaller Planes?

If you’re flying on a regional jet like an Embraer ERJ-145 or a Bombardier CRJ-200 there’s a good chance you’ll have to gate-check your carry-on, even if it meets the size requirements.

These planes just don’t have the overhead space for larger bags.

What Other Extra Items You Can Bring for Free?

Good news, you can bring a few extra items without them counting toward your carry-on allowance.

These include:

• A book or magazine
• Medical assistive devices
• An umbrella or coat
• Infant safety seats

Can You Get Away With an Oversized Carry-On?

What if your carry-on is just slightly bigger than the allowed size? Well, you might get away with it if it doesn’t look too large.

Some travelers manage to squeeze oversized bags into the sizer without a problem.

But there’s always a risk if your bag is flagged at the gate, you’ll have to check it, pay a fee, and possibly wait at baggage claim.

If you’re unsure about your bag, it’s important to measure and check your bag dimensions before heading to the airport.

Unlike some international airlines, American Airlines doesn’t have a strict weight limit for carry-on bags on most flights.

Some international routes do have weight restrictions, so it’s best to double-check before you fly.

Carrying Liquids on American Airlines Flights

AA follows the standard TSA regulations when it comes to liquids: Each container must be 3.4 oz (100 ml) or less and placed in a quart-sized bag.

Exceptions?.

Yes, baby food and medications are exempt from the TSA liquid rules.

If you’re traveling with these, you can bring more than the usual limit.

Final Thoughts

So, how strict is American Airlines with carry-on size? It depends.

While they don’t always check bags, it’s best to stick to the size rules to avoid extra fees and delays.
