American Airlines operates unified baggage rules across its mainline fleet and American Eagle regional connections. Checked baggage fees vary depending on whether you pre-pay online or pay at the airport counter, as well as your cabin class, destination, elite status, or credit card benefits.
American Airlines includes one free personal item (18 x 14 x 8 inches) and one free standard carry-on bag (22 x 14 x 9 inches) for all passengers across all cabin classes, including Basic Economy. Standard domestic checked bags cost $35 online ($40 at the airport) for the 1st bag and $45 for the 2nd bag, capped at 62 linear inches and 50 lbs in Main Cabin. Passengers in premium cabins, AAdvantage elite members, eligible AAdvantage credit cardholders, and active-duty US military receive complimentary checked bag allowances.

How BaggageBase Checks This Information
BaggageBase prioritizes official airline policy disclosures, tariff filings, contracts of carriage, and direct carrier booking platforms to verify all measurements, fee structures, and waiver conditions. Airline baggage rules and optional service charges update periodically across domestic and international route networks. Always check your specific booking confirmation on AA.com prior to departure to verify exact costs for your itinerary.
Carry-On Baggage & Personal Item Rules
American Airlines Personal Item Size and Rules
Every ticketed passenger on American Airlines is allowed one complimentary personal item. The dimensions for personal items cannot exceed 18 x 14 x 8 inches (45 x 35 x 20 cm). Your personal item must be small enough to fit completely underneath the seat directly in front of you during taxi, takeoff, and landing.
Certain essential or personal items do not count toward your one-personal-item allowance:
- Diaper bags for infants and small children
- Child safety seats and strollers
- Approved medical equipment (such as CPAP machines, breast pumps, or mobility aids)
- Outerwear, jackets, hats, or umbrellas
- Duty-free merchandise purchased after passing through security
Overhead Carry-On Bag Limits and Measurement Standards
In addition to a personal item, passengers are allowed one standard carry-on bag to place in the overhead bin. Carry-on bags must fit within 22 x 14 x 9 inches (56 x 36 x 23 cm). Soft-sided garment bags are accepted up to 51 total linear inches (130 cm total).
Measurement limits strictly include all external features. Protruding wheels, side handles, top telescoping handles, and bulging external pockets must fit within the dimensional box. American Airlines does not impose a published weight limit for standard carry-on bags on mainline flights, provided you can lift the bag into the overhead bin without assistance.
| Item | Allowance | Size or fit rule | Important condition |
|---|---|---|---|
| Personal Item | 1 Included Free | Max 18 x 14 x 8 in (45 x 35 x 20 cm) | Must fit completely under seat in front |
| Carry-On Bag | 1 Included Free | Max 22 x 14 x 9 in (56 x 36 x 23 cm) | Must fit in overhead bin; includes wheels/handles |
| Garment Bag | Alternate Carry-On | Max 51 linear inches (130 cm) | Soft-sided construction |
Does Basic Economy Include a Free Carry-On Bag?
Yes. American Airlines permits all Basic Economy passengers to bring one free personal item and one free standard carry-on bag on all domestic and international flights.
Unlike ultra-low-cost carriers detailed in our Allegiant Air baggage policy overview, American Airlines does not charge Basic Economy passengers for standard overhead carry-on bags. Your carry-on bag must still meet standard dimensional caps (22 x 14 x 9 inches) and fit into the overhead compartment.
Carry-On Rules for American Eagle Regional Flights
When flying on smaller regional aircraft operated by American Eagle (such as Bombardier CRJ or Embraer ERJ series aircraft), overhead bin space is noticeably limited. Standard roller bags that easily fit mainline jets will often fail to fit inside regional jet overhead bins.
American Airlines uses a Valet Gate-Check System (often called "Green Tagging" or "Yellow Tagging") on these aircraft:
- As you board on the jetbridge, gate agents tag larger carry-on bags that cannot fit inside the cabin.
- Your bag is loaded directly into the aircraft cargo hold at no additional charge.
- Upon arrival at your destination, your valet-tagged bag is delivered directly to the jetbridge as you deplane, rather than sent to the airport baggage claim carousel.
Checked Baggage Allowance & Fee Structure
American Airlines Checked Baggage Fees and Dimensions
Standard checked bags on American Airlines must adhere to maximum size and weight limits:
- Maximum Linear Dimensions: 62 total linear inches (158 cm) calculated by adding Length + Width + Height.
- Maximum Weight Cap: 50 lbs (23 kg) for Basic Economy, Main Cabin, and Premium Economy.
- Premium Weight Cap: 70 lbs (32 kg) standard allowance for Business Class and First Class passengers.
American Airlines offers a $5 discount on the first domestic checked bag if you pay for it online via AA.com or through the American Airlines mobile app during the 24-hour pre-flight check-in window. Paying at the airport counter incurs higher rates.
Domestic Checked Baggage Fee Schedule
Fees for standard checked bags on domestic US flights (including Puerto Rico and the US Virgin Islands) are structured as follows:
| Bag Order | Online / App Payment (Pre-Flight) | Airport Counter Payment | Max Weight Cap | Max Linear Size |

Note: Checked bag fees are non-refundable and apply per passenger each way.
Route Variations & International Baggage Rules
International & Regional Checked Baggage Policy Variations
International checked baggage allowances vary significantly based on route distance, destination region, and purchased fare class.
While domestic Main Cabin fares require paying out-of-pocket for all checked bags, long-haul international Main Cabin tickets generally include at least one free checked bag up to 50 lbs (23 kg). However, long-haul Basic Economy fares on international routes frequently require a fee for the first checked bag.

Special Baggage, Infants & Equipment Overview
Infant and Child Equipment
American Airlines allows parents and guardians to travel with essential child care equipment without added cost:
- Strollers and Car Seats: You can check one stroller and one car seat free of charge at the ticket counter or gate for each traveling child.
- Diaper Bags: One diaper bag per child is permitted as a free carry-on item in addition to your standard personal item limit.
Medical and Mobility Devices
Assistive mobility devices (wheelchairs, crutches, walkers) and approved medical equipment (CPAP machines, breast pumps) are carried free of charge. Medical items do not count toward your carry-on or personal item caps.
Sports Equipment, Musical Instruments & Pets
- Sports Gear: Items such as golf bags, skis, snowboards, and hockey equipment count as standard checked bags. Standard 1st or 2nd checked bag fees apply. Oversize fees are waived for standard equipment, but overweight fees apply if the item exceeds 50 lbs (23 kg).
- Musical Instruments: Small instruments (violins, flutes) can be brought as standard carry-ons if they fit overhead. Larger instruments require checking in a protective hard-shell case or purchasing a dedicated passenger seat.
- In-Cabin Pets: American Airlines charges a $125 to $150 carry-on pet fee per carrier each way. The pet carrier replaces your standard carry-on bag and must fit beneath the front seat.
Airport Enforcement & Gate-Checking Procedures
American Airlines gate agents actively monitor carry-on bag dimensions before boarding. Sizer units are placed at check-in desks and departure gates. If a carry-on exceeds 22 x 14 x 9 inches or space in the overhead bins runs out during boarding, the bag must be gate-checked.
On mainline flights, if your bag is gate-checked to your final destination, applicable checked baggage fees may be assessed at the gate if you have already used or exceeded your checked baggage allowance.
5-Step Action Checklist Before Flying American Airlines
Follow these practical pre-flight steps to avoid unexpected counter fees and gate penalties.
- Measure Outer Edges: Measure carry-on bags including wheels, handles, and stuffed side pockets to fit within 22 x 14 x 9 inches.
- Weigh Your Checked Luggage: Keep Main Cabin checked bags under 50 lbs (23 kg) to avoid the steep $100 overweight fee tier.
- Pre-Pay Online Within 24 Hours: Pay for domestic checked bags on AA.com or the mobile app during online check-in to save $5 on your first bag.
- Link Your AAdvantage Account: Attach your credit card-linked AAdvantage number to your reservation before check-in to auto-apply free checked bag perks.
- Prepare for Regional Jets: Keep medications and key valuables in your personal item on American Eagle flights, as larger carry-ons are valet-tagged at the jetbridge.
