What You'll Learn

Checking in online or via the app
Checking in online or via the American Airlines app is simple and convenient. You can check in on aa.com and via the app starting 24 hours before your flight's scheduled departure time. It is important to note that some airports require you to check in earlier, so be sure to check the minimum check-in time for your specific airport.
To check in online, go to aa.com and log in to your account using your username and password. If you don't already have an account, you can create one by choosing a username and password. Once logged in, you can access your upcoming flight information on the homepage.
To check in via the app, download the American Airlines mobile app and log in to your account. If you're logged in and have a flight departing within 72 hours, your upcoming flight information will be displayed on the homepage. If you don't see your flight, log out and log back in again, ensuring that the "Keep me logged in" option is disabled. Then, your upcoming trips will display on the homepage.
If you are travelling with an infant under 2 or don't have a seat assignment, you may be redirected to aa.com to check in. This usually happens if it's outside the check-in window of 1–24 hours before a domestic flight or 2–24 hours before an international flight.

Checking in at the airport kiosk
First, it is important to note that you can check-in online or via the American Airlines app starting 24 hours before your flight and up to 45 minutes (for domestic flights) or 60 minutes (for international flights) before scheduled departure. If you prefer to check in at the airport, simply proceed to the kiosks usually located near the baggage drop-off area.
At the kiosk, you will need to enter your reservation or confirmation code to initiate the check-in process. Follow the prompts on the screen to check in for your flight and make any necessary trip updates, such as adding bags or requesting upgrades. If you are travelling with an infant under two years of age, you can also add this information at the kiosk.
Once you have completed the check-in process, the kiosk will print your boarding pass. You can then proceed to the baggage drop-off area to check your bags. At select airports, you can use Express Bag Tags to save time. Simply scan your boarding pass at the kiosk to print your bag tags, and then attach them to your checked bags.

Travelling with firearms
If you are travelling with firearms, you must declare them to an agent at check-in. Firearms must be unloaded and locked in a hard-sided container and transported as checked baggage only. You will open the case for an AA representative to show them what's inside. Do not take the firearm out of the case. You will sign a slip, and it will go inside the gun case. You will then close the case and lock it with non-TSA locks.
Different airports have different procedures, so it is important to research the specific rules of your departure and arrival airports. For example, at PHL, your firearm will be taken to the back and you will wait for it to clear. At SEA, you will be taken to a TSA station and the agent will make you open the case so they can swab it.
Laws on the possession of firearms differ between states and countries. Please check the requirements of your destination before you travel. Within the U.S., you can only travel with firearms and ammunition if you’re over 18 years old. You can travel with up to 11 lbs/5 kg of small arms ammunition for sporting purposes in your checked bags if it is securely packed in the original manufacturer's packaging or packaged in fiber, wood, metal or other packaging specifically designed to carry small amounts of ammunition.
All Law Enforcement Officers (LEOs) flying armed are required to check in with an American Airlines agent at the airport before boarding the flight on which they will have their weapon accessible. State, local and territorial LEOs flying armed must submit a National Law Enforcement Telecommunications System (NLETS) message during airport check-in to the American Airlines airport agent.

Travelling with pets
American Airlines allows cats and dogs to travel in the cabin, but they must stay in an approved carrier that fits under the seat. Larger dogs can travel in the cargo hold of some planes. There is a fee to travel with your pet, which you can pay at the airport or at a travel centre with a credit card or paper voucher (where accepted).
When checking in your pet, there are specific requirements for their kennel. It must be:
- Large enough for your pet to stand, turn, sit and lie down in a natural position (without touching any side or the top of the container)
- Within the maximum size and weight requirements of the aircraft you're travelling on
- Made of wood, metal, plastic or similar materials
- Rigid and secure enough so the animal cannot escape through gaps or poke any body parts through the container
- Leak and escape-proof with a secure fastened door
- Well-ventilated on at least three sides for domestic US travel and four sides for international travel
- Equipped with separate food and watering dishes attached securely inside the kennel
- Equipped with a small bag of food for a 24-hour period attached to the top
- Clean and have absorbent material (no straw, hay or wood shavings)
If you are travelling on a connecting flight, checked pets will only be able to connect through certain cities. Your pet must have been fed and offered water within four hours before delivering them to the airplane, and you must provide feeding and watering instructions for a 24-hour period. Unless specified by a vet, you cannot leave instructions saying 'no food or water'.
American Airlines does not accept pets that have been sedated or tranquilized. Pets that have been given sedatives or tranquilizers are at a higher risk of respiratory and cardiovascular problems at high altitudes.
If you are travelling with a service animal, you must submit the U.S. Department of Transportation (DOT) Service Animal Air Transportation Form at least 48 hours before your flight. You must also carry an ID card or valid certificate from the organisation that trained or supplied the animal.
