Did you know American Airlines carry on policy is changing? The airline is removing those metal bag sizers from boarding gates at airports to streamline your boarding experience.

Understanding American Airlines carry-on policy helps you avoid unexpected fees and ensures smooth travel from check-in to boarding.

• Size limits are strictly enforced: Carry-on bags must not exceed 22 x 14 x 9 inches (including wheels and handles), with personal items limited to 18 x 14 x 8 inches.
• Weight matters too: Despite common misconceptions, American Airlines enforces a 40-pound weight limit for carry-on bags to ensure passenger safety.
• Prepare before you travel: Measure your luggage at home and check in early to secure overhead bin space and avoid gate-checking fees.
• Know your exceptions: Families get extra allowances for diaper bags and child equipment, while service animals and medical devices don’t count against baggage limits.
• Follow TSA liquid rules: All liquids must follow the 3-1-1 rule (3.4 oz containers in one quart-sized bag), regardless of American Airlines generous carry-on policy.

Recent policy changes removed physical bag sizers from gates, but size restrictions remain unchanged. Gate agents now use their judgment, though they’re instructed to “err on the side of the customer” for slightly oversized bags. Smart packing and early preparation remain your best defense against unexpected baggage fees.

Despite this change, American Airlines carry on size restrictions remain unchanged. You’re still permitted one carry-on bag with dimensions not exceeding 22 x 14 x 9 inches and one personal item that fits under the seat in front of you. However, if your bag exceeds these limits, you might face fees ranging from $30 to $200 when checking it at the gate.

The total size of your carry-on, including wheels and handles, is what counts. Interestingly, American Airlines doesn’t impose weight limits for carry-on bags across any of its fares, although size restrictions are strictly enforced.

In this article, we’ll break down everything you need to know about American Airlines baggage policy – from exact dimensions and exceptions to smart packing tips that help you avoid unexpected fees at the gate.

How many bags can you bring on American Airlines Flight?

American Airlines permits every passenger to bring one carry-on bag and one personal item onboard at no additional charge, regardless of fare type. Your carry-on must fit in the overhead bin, while your personal item needs to fit under the seat in front of you.

For carry-on bags, the dimensions cannot exceed 22 x 14 x 9 inches (56 x 36 x 23 cm), including handles and wheels. This measurement is strictly enforced, as your bag must fit in the sizer at the airport. Furthermore, American Airlines enforces a carry-on weight limit of 40 pounds (18 kg). You should be able to lift your bag into the overhead bin without assistance.

Personal items have stricter size limits—maximum dimensions of 18 x 14 x 8 inches (45 x 35 x 20 cm). Acceptable personal items include:

• Small backpacks
• Laptop bags
• Purses or handbags
• Camera bags
• Briefcases

Notably, certain items don’t count against your baggage allowance. These include diaper bags (one per child), breast pumps, small soft-sided coolers for breast milk, child safety seats, strollers, and medical or mobility devices.

American Airlines hand luggage vs checked bags

The primary difference between carry-on and checked luggage lies in the handling process and size restrictions. Your hand luggage stays with you throughout the journey, whereas checked bags are transported in the cargo hold.

Checked bags must adhere to specific size and weight limitations. The total dimensions (length + width + height) cannot exceed 62 inches (158 cm). Weight restrictions are typically 50 pounds (23 kg) for standard passengers, though First and Business class passengers may be allowed up to 70 pounds (32 kg) for their free checked bags.

In contrast to free carry-ons, checked baggage often incurs fees. As of November 2024, the first checked bag fee is $40 ($35 if paid online) and the second checked bag costs $45 for travel within the U.S., Puerto Rico, and U.S. Virgin Islands. For travel to/from Canada, Caribbean, Mexico, Central America, and Guyana, the first checked bag fee is $35 and the second is $45.

Most passengers can check up to 10 bags on American Airlines for domestic, trans-Atlantic, and trans-Pacific flights, though travelers to/from Mexico, Caribbean, Central America, South America, or Brazil are limited to 5 checked bags.

Basic economy vs main cabin American Airlines carry-on

Contrary to what some travelers might expect, Basic Economy passengers on American Airlines receive the same carry-on baggage allowance as Main Cabin passengers. Both fare types permit one carry-on bag and one personal item at no extra cost.

The key difference lies in checked baggage benefits. Basic Economy fares generally don’t include free checked bags, while certain Main Cabin tickets (particularly for long-haul international routes) may include one complimentary checked bag.

Several exceptions exist to these basic rules. AAdvantage status members maintain their checked baggage benefits even when booking Basic Economy. Similarly, eligible AAdvantage credit cardholders can still enjoy their first checked bag free when flying within the U.S. and Canada on flights marketed and operated by American Airlines.

For travel to/from Australia and New Zealand, the policy varies based on when tickets were issued. For tickets issued before November 13, 2024, Basic Economy includes no free checked bags, but for tickets issued on or after that date, Basic Economy includes one free checked bag.

While baggage allowances differ between these fare classes, the actual in-flight experience remains largely the same. Both Basic Economy and Main Cabin passengers sit in the same cabin area and receive identical in-flight services, including snacks, drinks, and entertainment options.

American Airlines Carry-On Dimensions and Weight Explained

_{Image Source: Travelpro}

“There are no listed weight restrictions for carry-on luggage.” — American Airlines Official Policy, Official airline carry-on weight policy

Understanding the exact measurements for your carry-on luggage prevents last-minute surprises at the airport. American Airlines maintains specific size and weight restrictions for cabin baggage to ensure everyone’s belongings fit safely aboard their aircraft.

American Airlines cabin baggage dimensions

The maximum dimensions permitted for carry-on bags are precisely defined to accommodate the limited space in overhead compartments. For standard carry-on luggage, American Airlines specifies that the total size, including handles and wheels, must not exceed 22 x 14 x 9 inches (56 x 36 x 23 cm). These measurements are non-negotiable and apply to all types of carry-on bags, whether they’re suitcases, backpacks, or duffel bags.

For travelers preferring to bring formal attire, American Airlines offers an alternative: you may substitute your standard carry-on with a soft-sided garment bag. These garment bags must not exceed 51 inches (130 cm) when you add the length, width, and height. This accommodation helps passengers transport suits, dresses, and other formal wear without excessive wrinkling.

Your personal item dimensions are equally important. These items must fit comfortably under the seat in front of you and cannot exceed 18 x 14 x 8 inches (45 x 35 x 20 cm). Common personal items include purses, laptop bags, camera cases, or small backpacks.

What size carry-on is allowed on American Airlines?

The standard carry-on size allowed on American Airlines flights is 22 x 14 x 9 inches (56 x 36 x 23 cm). This measurement is absolute—anything larger risks being gate-checked, potentially incurring additional fees.

Until recently, American Airlines used physical “sizer” boxes at gates to verify compliance. While the airline has begun removing these physical sizers to streamline the boarding process, the size restrictions remain unchanged. Gate agents still have the authority to require checking oversized bags.

Consequently, if your bag exceeds these dimensions, you’ll likely face checked baggage fees ranging from $30 to $200, depending on your destination and how many bags you’ve already checked. To avoid this expense, measure your luggage at home before heading to the airport.

For both international and domestic flights on American Airlines, the carry-on size requirements remain identical. This consistency makes packing simpler for frequent travelers regardless of destination.

When measuring your bag, remember that wheels and handles count toward the total dimensions. A bag that’s 22 inches high with additional extending handles might exceed the permitted size when fully measured. Additionally, your bag must be capable of fitting in the overhead bin or under the seat—this is the ultimate test regardless of measured dimensions.

Does American Airlines weigh carry-on bags?

Unlike some conflicting information online, American Airlines does indeed have a weight restriction for carry-on luggage. The maximum weight allowed is 40 pounds (18 kg). This limit ensures passengers can safely lift their bags into overhead bins without assistance and prevents excessive strain on the aircraft’s storage structures.

Interestingly, while this weight limit exists, not all sources confirm it. Some travel sites incorrectly claim American Airlines doesn’t have weight restrictions for carry-ons. For safety, always assume the 40-pound limit applies when packing.

If your carry-on exceeds this weight limit, you may be required to check it at the gate. This could result in unexpected fees and the inconvenience of waiting at baggage claim upon arrival.

Besides weight considerations, ensure your bag is manageable enough to lift into overhead bins independently. Flight attendants may assist but aren’t required to help with extremely heavy items. Moreover, overweight bags in overhead compartments pose safety risks during turbulence or emergency situations.

American Airlines Exceptions and Extra Allowances

Beyond standard baggage allowances, American Airlines offers specific accommodations for passengers with unique needs. These exceptions ensure traveling remains accessible for families, those requiring assistance, and pet owners.

American Airlines baggage policy for families

Families traveling with young children receive additional allowances that make journeys more manageable. Specifically, parents can bring several child-related items that don’t count toward their standard baggage limits.

When traveling with an infant or child, you may bring one diaper bag per child as an additional free item. This accommodation acknowledges the necessity of having baby essentials readily available during flights. Accordingly, breast pumps and small soft-sided coolers containing breast milk also don’t count against your carry-on or personal item allowance.

For international flights with an infant on your lap, American Airlines provides even more flexibility. You’re permitted to check one free bag for the infant with an airport agent, provided it doesn’t exceed 25 lbs (11 kgs) and adheres to standard carry-on dimensions of 22 x 14 x 9 inches.

Each ticketed customer traveling with a child or to adopt can check one stroller and one car seat free of charge. You can check both items at the ticket counter or check one at the gate and one at the counter. Non-collapsible strollers and stroller wagons without built-in safety straps must be checked at the ticket counter.

Service animals and assistive devices

American Airlines makes accommodations for travelers with disabilities by allowing service animals and assistive devices aboard flights without counting against baggage limits.

The airline defines a service animal as a dog individually trained to perform tasks for someone with a disability. These disabilities may include visual impairments, deafness, seizures, mobility impairments, or post-traumatic stress disorder. Subsequently, only dogs qualify as service animals under American Airlines’ policy.

Service dogs fly in the cabin at no additional charge, provided they meet specific requirements. The animal must be harnessed, leashed, or tethered throughout the journey, be clean and well-behaved, and fit at your feet, under your seat, or on your lap if small enough. Animals must be over 4 months old to travel as service animals.

Undeniably important is the distinction between service animals and emotional support animals. American Airlines no longer recognizes emotional support animals as service animals – they must travel as regular pets with applicable fees.

Wheelchairs and assistive devices such as walkers and walking canes can be brought onto flights at no charge, in addition to standard carry-on allowances. This policy aligns with Department of Transportation regulations requiring airlines to allow assistive devices as free carry-ons consistent with safety rules.

American Airlines pet carrier size in cabin

For passengers traveling with pets, American Airlines permits small cats and dogs in the cabin, substituting for your carry-on allowance. A fee of USD 125.00 applies when traveling with pets as carry-on.

Regarding carrier dimensions, soft-sided carriers (recommended) must not exceed 18 x 11 x 11 inches (46 x 28 x 28 cm) for all flights. Hard-sided carriers face different restrictions: 19 x 13 x 9 inches (48 x 33 x 22 cm) for American Mainline flights and 16 x 12 x 8 inches (40 x 30 x 20 cm) for American Eagle flights.

Your pet carrier must be secure, padded, made of water-repellent material, and have nylon mesh ventilation on three or more sides. The animal must be small enough to fit comfortably inside the closed carrier.

Pet travel comes with restrictions based on destination. You can travel with a pet on flights up to 12 hours or to/from select locations within the 48 contiguous United States, Canada, Alaska, Mexico, Puerto Rico, St. Croix, and St. Thomas. Fortunately, you’re allowed one additional item with your pet carrier – either a personal item or a carry-on bag that meets requirements.

Remember that when traveling with a pet in cabin, you cannot sit in bulkhead seats, exit row seats, or certain premium cabin seats due to FAA safety requirements. This ensures both pet comfort and passenger safety throughout the flight.

American Airlines Restricted and Prohibited Items

Packing safely for your American Airlines flight requires knowing what items are restricted or prohibited in carry-on bags. The airline follows Transportation Security Administration (TSA) guidelines while enforcing additional regulations to ensure passenger safety.

TSA rules for liquids and gels

The TSA enforces the 3-1-1 rule for liquids, gels, and aerosols in carry-on bags. This means:

• Containers must not exceed 3.4 ounces or 100 milliliters
• All containers must fit in one quart-sized, clear, resealable bag
• Each passenger is limited to one quart-sized bag
• Common items subject to this rule include toothpaste, shampoo, conditioner, mouthwash, and lotion

Some exceptions exist for this rule. Duty-free liquids purchased internationally are allowed in carry-ons if they’re packaged in secure, tamper-evident bags, show no signs of tampering, and were purchased within 48 hours with receipt present. Liquids for medical purposes or special needs can exceed the 100ml limit, though agents may request verification.

Hazardous items not allowed in carry-ons

Federal law prohibits numerous hazardous materials in carry-on luggage. Violating these regulations could result in imprisonment up to five years and penalties of $250,000 or more. Prohibited items include:

• Explosives and fireworks
• Compressed gasses
• Flammable liquids and solids (paints, lighter fluid)
• Oxidizers and poisons
• Corrosives and radioactive materials
• Insect sprays and pool chemicals
• Self-defense sprays (pepper spray, mace)
• Alcoholic beverages exceeding 3.4 ounces
• Propane heaters and internal combustion engines

Remember that common household items can become dangerous at altitude because changes in temperature and pressure might cause leaks, toxic fumes, or fires.

Can I take my makeup bag on an American Airlines flight?

Yes, you can bring your makeup bag on American Airlines flights, yet certain rules apply. For liquid makeup products:

• Foundation, liquid lipsticks, and similar liquid products must be 3.4 oz (100ml) or smaller
• These liquids must be placed inside your quart-sized clear plastic bag with other liquids
• Each liquid container cannot exceed 3.4 oz, with a maximum of 1 liter total and 10 containers per passenger

For non-liquid makeup items:

• Powder makeup, solid lipsticks, and solid deodorants aren’t restricted by the 3-1-1 rule
• These items can be packed freely in your carry-on bag

Practically speaking, many travelers report inconsistent enforcement of the clear bag requirement for makeup. Nevertheless, following official guidelines ensures you won’t have expensive products confiscated at security checkpoints.

American Airlines Policy Updates and Seasonal Restrictions

Recently, American Airlines implemented significant changes to its carry-on procedures. These updates affect both policy enforcement and seasonal restrictions that vary by destination and time of year.

American Airlines Carry-on 2025 policy update

As of October 6, 2025, American Airlines removed metal bag sizers from boarding gates at airports nationwide. This change aims to streamline the boarding process for customers. Instead of requiring passengers to physically fit their bags in sizers, gate agents now “use their judgment” about whether a bag is oversized. According to internal memos, agents are instructed to “err on the side of the customer” when bags appear only slightly oversized.

Despite the removal of physical sizers, the actual carry-on size restrictions remain unchanged. Bag sizers will still be available in airport lobbies for passengers to check their luggage dimensions before proceeding to security checkpoints.

Carry-on restrictions for American Airlines domestic flights

Throughout American Airlines’ network, the standard carry-on allowance applies to domestic flights: one carry-on bag and one personal item per passenger. Your carry-on must fit in the overhead bin or under the seat in front of you.

Effectively November 13, 2024, American Airlines updated its checked baggage fees. The first checked bag now costs $40 ($35 if paid online) and the second checked bag costs $45 for travel within the U.S., Puerto Rico, and U.S. Virgin Islands.

Seasonal limits on bag count and size

For tickets issued on or after August 26, 2025, for travel on or after October 1, 2025, passengers with AAdvantage Executive Platinum status, AAdvantage Platinum Pro status, or oneworld Emerald status are limited to no more than 2 free bags when traveling to or from Cuba.

From May 24 through September 12, 2025, each passenger is allowed only 2 checked bags on flights to several destinations, regardless of status or cabin class:

• Caribbean: Saint Kitts and Nevis
• El Salvador: San Salvador
• Honduras: San Pedro Sula, Comayagua
• Mexico: Aguascalientes, Monterrey, Tampico, Zacatecas

Overall, American Airlines enforces year-round limitations for select routes, with certain destinations having a maximum of just 2 or 3 checked bags permitted.

American Airlines Smart Travel Tips to Avoid Fees

_{Image Source: Send My Bag}

Avoiding unexpected baggage fees requires strategic preparation and knowledge of how American Airlines enforces its carry-on policy in practice. Savvy travelers can use several proven techniques to keep their bags with them throughout their journey.

How strict is American Airlines with carry-on size?

American Airlines maintains relatively strict enforcement of carry-on size limits. Gate agents check “suspicious” bags using sizers at departure gates, especially on busier flights when overhead space becomes limited. Even a bag that’s just one inch over the limit might result in a $30 fee. The airline monitors both size and weight restrictions, unlike some competitors that only enforce size limitations. For regional flights on American Eagle® planes, which have limited overhead bin space, bags larger than personal item dimensions must be valet-checked at the gate.

Tips to avoid gate-checking your bag

To prevent involuntary gate-checking, consider these practical strategies:

• Check in early—this simple step significantly improves your chances of finding available overhead space
• Choose seats toward the front of the plane or those with early boarding privileges
• Join American’s loyalty program for early boarding benefits
• Opt for soft-sided bags rather than hard-shell suitcases, as gate agents typically allow soft bags through even when bins are nearly full
• Arrive at your gate early, as agents often begin tagging carry-ons for gate check when anticipating a full flight

Labeling and measuring your bag at home

Prior to departure, take time to measure your luggage properly. Use a tape measure to verify your bag’s dimensions, including wheels and handles. Remember that advertised luggage sizes often exclude wheels, so verify actual dimensions. As a precaution, always label all carry-on bags with your contact information in case they need to be checked unexpectedly. This simple step ensures your bag can be quickly returned if it gets separated from you.
