Verdict: Your first checked domestic bag is $50 and your carry-on is free in every cabin, but Basic Economy now pays $5 more per checked bag.
American Airlines baggage fees start at $50 for the first checked bag on a domestic flight in Main Cabin, or $45 if you pay online before the airport, as of July 2026. The second bag is $60, or $55 online. Basic Economy tickets pay $5 more on each of those bags.
Your carry-on bag and one personal item are free in every cabin, including Basic Economy. Those are the numbers most people come here for, so they are the first thing on the page.
Everything after this explains the parts that trip people up: what “domestic” actually covers, when an overweight bag doubles your cost at the counter, and the three ways to get the checked-bag fee down to zero. Every dollar figure below is taken from American’s own published fee schedule, verified for this article on July 7, 2026. American re-tiered these fees more than once across 2025 and 2026, so if another site shows you a $35 or $40 first bag, that figure is out of date.
For travel within and between the United States, Puerto Rico, and the US Virgin Islands, American charges $50 for the first checked bag in Main Cabin and $60 for the second, as of July 2026. Pay for those bags online through aa.com or the app up to two hours before departure and each price drops by $5, to $45 and $55. That $5 online discount is the single easiest saving here, and it applies per bag, each way.
A standard checked bag is one that weighs up to 50 pounds (23 kg) and measures up to 62 linear inches (length plus width plus height). Stay under both limits and you pay only the fee above. Go over either one and American adds an overweight or oversize charge on top, which is covered further down.
Premium Economy, Business, and First fares include free checked bags, so the fee only applies to Main Cabin and Basic Economy passengers. If you booked one of those premium cabins, your first bag or two are already included and you owe nothing extra for standard bags.
American lets you bring one carry-on bag and one personal item at no charge in every cabin, and that includes Basic Economy. This is worth stating plainly because the rule is the opposite of Spirit and Frontier, where a full-size carry-on costs money. On American, the carry-on is free whether you booked First or the cheapest Basic Economy fare.
The size limits are firm. Your carry-on bag cannot exceed 22 x 14 x 9 inches, and it has to fit the sizer at the gate. Your personal item, such as a purse, laptop bag, or small backpack, cannot exceed 18 x 14 x 8 inches and has to fit under the seat in front of you.
Here is the honest caveat. Basic Economy passengers board in the last group, and overhead bin space is often full by then. If the bins are full when you reach your seat, a gate agent will check your carry-on to the hold.
That gate-check is usually free, but you lose the bag until baggage claim. If you were counting on keeping medication or valuables with you, plan for the bin to be gone. The carry-on allowance is real, but the overhead space is not guaranteed.
This table covers travel within and between the US, Puerto Rico, and the US Virgin Islands, as of July 2026. Prices in parentheses are the discounted online rate paid before the airport. Basic Economy figures apply to tickets issued on or after May 18, 2026.
| Bag | Basic Economy | Main Cabin | Premium Economy / Business / First |
|---|---|---|---|
| Carry-on + 1 personal item | Free | Free | Free |
| 1st checked bag | $55 ($50 online) | $50 ($45 online) | $0 |
| 2nd checked bag | $65 ($60 online) | $60 ($55 online) | $0 |
| 3rd checked bag | $200 | $200 | $200 |
| 4th checked bag | $200 | $200 | $200 |
The fees apply per person, each way. They are non-refundable once paid at the airport, though American will review a claim if you believe you were charged in error, filed within 45 days. If you want a broader picture of what an airline does and does not owe you when something goes wrong, our guide to what US airlines owe you for a canceled or delayed flight covers the refund rules that sit alongside these fees.
One note on scope. “Domestic” here means the US, Puerto Rico, and the US Virgin Islands. International routes carry their own allowances, and many of them include a free first checked bag in Main Cabin that domestic routes do not.
If your itinerary crosses a border, check the fee for that specific region rather than assuming the domestic number.
An overweight or oversize fee is charged on top of the standard checked-bag fee, not instead of it. This is the part travelers miss at the counter, so read it before you pack. If a single bag is both overweight and oversize, American charges only the higher of those two fees, plus the base checked-bag fee.
Overweight fees for domestic travel, as of July 2026, work in tiers:
| Bag weight | Domestic fee (added to base) |
|---|---|
| 50 to 53 lbs (23 to 24 kg) | $30 |
| 53 to 70 lbs (24 to 32 kg) | $100 |
| 70 to 100 lbs (32 to 45 kg) | $200 |
| Over 100 lbs (45 kg) | Not accepted on most flights |
That first tier is where the surprise lives. A bag that weighs 51 pounds is one pound over the limit and costs you $30 on top of the $50 checked-bag fee, turning a $50 bag into an $80 bag.
Weigh it at home. A cheap luggage scale pays for itself on the first trip.
Oversize fees follow the same add-on logic. A bag over 62 linear inches but no more than 65 inches costs an extra $30. A bag between 65 and 115 linear inches costs an extra $200 on domestic routes.
American does not accept checked bags over 115 linear inches on flights it operates. Remember the rule from the top of this section: if your bag is both too heavy and too big, you pay the higher of the two charges, plus the base fee, not all three.
The most reliable way to check a bag for free is to hold status or a co-branded card, because both waive the first checked-bag fee for you and, in most cases, for people traveling with you. Here are the four routes to a free bag, in the order most travelers can actually use them.
Fly a premium cabin. Premium Economy, Business, and First fares include free checked bags. If you are already in one of those cabins, you owe nothing for standard bags.
Hold AAdvantage Gold status or higher. Gold and above get the first checked bag free for the member and for guests on the same reservation, on flights marketed and operated by American. Elite members and premium-cabin passengers also get a higher weight allowance of 70 pounds per bag before an overweight fee applies, instead of the usual 50.
Carry an American co-branded credit card. Most Citi / AAdvantage cards give the first checked bag free on domestic American itineraries for the cardholder and up to four companions on the same reservation. The higher-tier Globe and Executive cards extend that to up to eight companions. For a family of four, one qualifying card zeroes out four first-bag fees per direction. Weigh the card’s annual fee against how often you actually check bags before you sign up.
Fly a route that includes a free bag. Several international regions include a free first checked bag in Main Cabin. That does not help on a domestic hop, but it is worth checking your specific route before paying.
American updated its bag fees for tickets issued on or after May 18, 2026, and the change did two things. It raised the standard checked-bag prices to the figures shown above, and it made American the first US carrier to charge Basic Economy passengers more for checked bags than Main Cabin passengers. The gap is $5 per bag, so a Basic Economy first checked bag runs $55 against Main Cabin’s $50.
The practical takeaway is narrow. If you are deciding between a Basic Economy fare and a Main Cabin fare and you plan to check a bag, add $5 per bag per direction to the Basic Economy price before you compare. On a round trip with one checked bag each way, that is $10, plus the loss of seat selection and boarding position that Basic Economy already carries.
Are American Airlines carry-on bags free? Yes. One carry-on bag and one personal item are free in every cabin, including Basic Economy, as of July 2026. The carry-on must fit within 22 x 14 x 9 inches and the personal item within 18 x 14 x 8 inches.
How do I get two free checked bags on American? Fly Business or First, which include checked bags, or combine benefits: AAdvantage Gold status or an American co-branded card covers the first bag, and Premium cabins or higher elite tiers extend the free allowance further. There is no single fare that gives two free checked bags in Main Cabin without status, a card, or a qualifying route.
How much is the first checked bag on American? $50 in Main Cabin, or $45 if you pay online before the airport, for domestic travel as of July 2026. Basic Economy is $55, or $50 online.
Does American charge more for a bag over 50 pounds? Yes. A domestic bag between 50 and 53 pounds costs an extra $30 on top of the checked-bag fee. Between 53 and 70 pounds it is an extra $100, and between 70 and 100 pounds it is an extra $200. Bags over 100 pounds are not accepted on most flights.
Is it cheaper to pay for bags online? Yes. Paying on aa.com or the American app up to two hours before departure saves $5 on each of the first and second checked bags, each way. See the current American Airlines bag fee schedule to confirm your route before you fly, since these fees change.

The personal item is free. The carry-on is the trap, and every bag costs more the later you pay. Frontier's real baggage fees and how to pay less.
Verdict: The personal item is the only free bag. The carry-on is the paid trap, and every bag costs the most at the gate.
Global entry vs TSA PreCheck: get PreCheck for domestic trips, Global Entry if you fly abroad since it includes PreCheck. Current prices and where CLEAR fits.
Verdict: Domestic flyers get TSA PreCheck; anyone flying internationally gets Global Entry because it includes PreCheck; CLEAR is an optional add-on, not a replacement.
