American Airlines travel is easier when you know the rules before you leave home. The most important steps are checking your identification and destination documents, meeting check-in and boarding deadlines, understanding your fare and baggage allowance, and reviewing any special rules for children, pets, service animals, or partner-operated flights.
Quick Answer
To fly American Airlines, adults need an acceptable ID for U.S. trips, while international travelers need a valid passport and any required visas or entry documents. Check in within American’s deadlines, arrive about two hours early for U.S. flights or three hours early for international trips, and confirm fare, bag, pet, and partner-airline rules before departure.
Key Takeaways
- U.S. travelers age 18 or older need a REAL ID-compliant license or another TSA-accepted ID.
- Online check-in normally opens 24 hours before departure, but international online check-in closes earlier than domestic check-in.
- Most American flights stop boarding 15 minutes before departure, so reaching the airport is not the same as reaching the gate on time.
- Basic Economy, checked-bag fees, seat benefits, and mileage earning changed in 2025 and 2026.
- The operating airline controls many check-in, baggage, pet, and onboard rules on partner flights.
American Airlines Travel Documents and ID Rules
Before you head to the airport, make sure the name on your reservation matches the identification or passport you plan to use. A mismatch can slow down check-in or security screening.
Identification for Flights Within the United States
Adult passengers age 18 or older must show an identification document accepted by the Transportation Security Administration. Since May 7, 2025, a standard state driver’s license that is not REAL ID compliant is no longer accepted by itself at TSA checkpoints. You can instead use another accepted document, such as a U.S. passport, passport card, permanent resident card, military ID, or trusted traveler card. Review the current TSA identification list before travel.
TSA generally does not require children under 18 to show ID for domestic travel, although American Airlines may request documents in special situations, including unaccompanied-minor travel.
Warning: Travelers age 18 or older who arrive without a REAL ID or another acceptable ID may need TSA ConfirmID. The current fee is $45, identity verification is not guaranteed, and the process can cause a missed flight.
Passports, Visas, and International Documents
Every international traveler, including an infant or child, needs the documents required by every country on the itinerary. This can include a passport, visa, transit visa, electronic travel authorization, health document, proof of onward travel, or parental consent letter.
Do not apply one six-month passport rule to every destination. Passport-validity rules vary by country. Some countries require six months of validity, while others use a shorter period. A U.S. passport card is not valid for international air travel. Check the American Airlines international travel page and the official government or consulate page for every destination and transit country.
If a child is traveling internationally with only one parent, with another adult, or alone, border officials may ask for proof of relationship and written consent from a parent or guardian who is not present. Requirements depend on the countries involved.
American Airlines Check-In Times and Boarding Passes
You can usually check in on aa.com or in the American Airlines app beginning 24 hours before departure. Online and app check-in normally remain available until 45 minutes before a flight within the United States and until 90 minutes before an international flight.
Checking in online does not replace airport bag-drop, document-check, security, or gate deadlines. American recommends arriving at least two hours before a flight within the United States and at least three hours before a flight departing from an airport outside the United States.
| Travel step | Typical American Airlines deadline |
|---|---|
| Online or app check-in opens | 24 hours before departure |
| Online check-in closes for U.S. flights | 45 minutes before departure |
| Online check-in closes for international flights | 90 minutes before departure |
| Airport check-in or bag drop for most U.S. flights | 45 minutes before departure |
| Airport check-in or bag drop for most international flights | 60 minutes before departure |
Some airports require earlier check-in. Review American’s current check-in and arrival rules for airport-specific exceptions before you travel.
Your boarding pass shows your flight number, boarding group, seat, scheduled boarding time, and gate. Keep checking the app or airport screens because gates and times can change.
Choose the Right American Airlines Fare and Bags
Compare the exact fare rules shown during booking. The cabin name alone does not tell you whether a ticket is refundable, changeable, or eligible for every benefit.
Fare Types Explained
- Basic Economy: This is American’s lowest Main Cabin fare. It normally cannot be changed after the 24-hour grace period, although limited exceptions apply. Basic Economy tickets bought on or after December 17, 2025, do not earn AAdvantage miles or Loyalty Points. Tickets bought on or after May 18, 2026, are also excluded from complimentary upgrades.
- Main Cabin: This offers more flexibility than Basic Economy. Many American-operated fares have no change fee, but you still pay any difference in fare.
- Premium Economy: This separate cabin is available on select longer routes and normally includes more space and additional services.
- Business or First: These cabins include premium seating and services, but refund and change terms still depend on the fare purchased.
- Fully flexible or refundable fares: These cost more but provide the strongest cancellation and change options. Always read the fare conditions before payment.
If you buy directly from American at least two days before departure, you generally have 24 hours from the original purchase time to cancel for a refund. After that period, the ticket’s fare rules apply. Read the current Basic Economy conditions before choosing the lowest fare.
Bag Rules and Fees
American allows one carry-on bag and one personal item in all cabins, including Basic Economy. A standard carry-on cannot exceed 22 x 14 x 9 inches, including handles and wheels. A personal item should not exceed 18 x 14 x 8 inches and must fit under the seat.
For most routes, a standard checked bag can measure up to 62 linear inches and weigh up to 50 pounds. Premium cabins may receive a higher complimentary weight allowance. Oversize, overweight, seasonal, and destination limits can still apply.
| Bag type or fare | Current rule to know |
|---|---|
| Carry-on | One carry-on up to 22 x 14 x 9 inches, plus one personal item |
| Main Cabin first checked bag on many U.S., Canada, Mexico, Caribbean, and Central America itineraries | $50 at the airport or $45 online for tickets issued on or after May 18, 2026 |
| Main Cabin second checked bag on those itineraries | $60 at the airport or $55 online |
| Basic Economy on those itineraries | Usually $5 more for the first and second checked bags |
| Free checked bags | May come with an eligible premium fare, route, AAdvantage status, or qualifying credit card |
Bag prices vary by route, ticket date, fare, status, and operating airline. Confirm your exact allowance through the American Airlines checked-bag policy.
Pro Tip: On eligible American-marketed and American-operated trips, you can pay for up to three checked bags online as late as two hours before departure. Online payment may save $5 on the first and second bag.
Pack spare lithium batteries, power banks, and e-cigarettes in your carry-on, not in checked baggage. If an agent gate-checks your carry-on, remove those items first. The FAA lithium-battery guide explains the current safety limits.
Firearms are not allowed in carry-on baggage, but they may be transported in checked baggage when legally permitted. They must be unloaded, placed in a locked hard-sided case, and declared to an airline agent at check-in. Local, state, federal, and international laws also apply.
How American Airlines Boarding and Gate Changes Work
Most American Airlines flights begin boarding 30 to 50 minutes before scheduled departure. Boarding ends 15 minutes before departure. If you are not on board by then, American may reassign your seat, and you cannot board after the aircraft door closes.
For a safer margin, American’s conditions of carriage tell travelers to be at the gate and ready to board at least 30 minutes before a domestic departure and 45 minutes before an international departure.
- Check your boarding group and scheduled boarding time in the app.
- Verify the gate again after clearing security.
- Stay near the gate because last-minute gate or aircraft changes can happen.
- Board only when your group is called, unless an agent approves early boarding.
Customers who need special assistance can request early boarding. Families with children under age 2 may also ask to board early. Review American’s boarding process before departure.
American Airlines Travel Tips for Kids and Pets
Traveling With Children
American says its system will look for seats together when a family travels with a child under 15 and does not already have assigned seats. If limited seats remain, the airline aims to seat each child under 15 beside at least one adult in the same party. Check seat assignments before travel and speak with an agent early if the arrangement does not work.
Each ticketed customer traveling with a child may check one stroller and one car seat free of charge. One item may be checked at the gate and the other at the ticket counter. Non-collapsible strollers and stroller wagons without built-in child restraints must be checked at the ticket counter.
Children ages 5 through 14 who travel alone must use American’s unaccompanied-minor service. The service is optional for ages 15 through 17. Children ages 5 through 7 can use nonstop flights only, while older children have limited connection options. These reservations must be made by phone, and the adult completing check-in should arrive at least two hours early. Review the unaccompanied-minor rules before booking.
Flying With Pets
American accepts carry-on cats and dogs that meet its size, age, kennel, route, and destination rules. The pet must remain inside an approved kennel that fits under the seat. Carry-on pets are limited to eligible flights, generally up to 12 hours, and some destinations do not allow them.
Pet space is limited, so confirm the pet in advance instead of arriving with an unlisted animal. Fees apply, and the pet carrier counts as your carry-on item. You may bring one additional item, either a personal item or a standard carry-on bag, if it meets the normal size rules. International animal-entry and return rules may require health records, permits, microchips, or a CDC Dog Import Form.
Service Animals
American accepts fully trained service dogs that meet federal and airline requirements. Emotional-support animals, comfort animals, service animals in training, and other species travel under the pet rules rather than as service animals.
American recommends submitting the U.S. Department of Transportation Service Animal Air Transportation Form at least 48 hours before departure. A second relief-attestation form is required for itineraries with a flight longer than eight hours. Partner airlines may require separate forms. Check American’s service-animal requirements before travel.
Special Assistance, Wheelchairs, and Medical Travel
You can request wheelchair or mobility help while booking or by contacting American before travel. Mobility devices do not count toward the normal carry-on allowance, and wheelchairs can be gate-checked and returned at the gate after landing.
Contact American early when traveling with a portable oxygen concentrator, battery-powered medical device, mobility device, or other equipment that may require approval or special handling. Keep essential medicine, identification, travel documents, and valuables in your carry-on.
Delays, Cancellations, and Missed Connections
Use the American app or flight-status page to watch for delays, cancellations, gate changes, and rebooking. If a cancellation or delay causes you to miss a connection, American states that it will rebook you on the next flight with available seats and reroute checked bags for the new itinerary.
If American cancels your flight or makes a qualifying significant itinerary change and you decline the replacement flight, travel credit, or other compensation, you may be eligible for a refund to the original payment method. For American’s current policy, a significant change includes an arrival change of three or more hours for a domestic itinerary or four or more hours for an international itinerary.
On a partner-operated flight, contact the operating carrier first because its airport, rebooking, and customer-care procedures may control the disruption.
What to Expect Onboard and After Landing
On most Wi-Fi-equipped American flights, you can stream free movies, TV shows, music, and other content to a phone, tablet, or laptop. Some aircraft also have seatback screens. Download the American app before departure and bring headphones because equipment varies by aircraft.
As of 2026, AAdvantage members can use free high-speed Wi-Fi sponsored by AT&T on most domestic flights and select international flights. Other paid connection options may remain on flights where free access is unavailable. Check the American Airlines Wi-Fi page for your aircraft.
After landing, use American’s bag tracker with your confirmation code or bag-tag number. If a bag is delayed or damaged, file a report before leaving the airport whenever possible. For U.S. trips, delayed bags should normally be reported within four hours of arrival. International delayed bags should be reported upon arrival and before leaving the airport.
American may also send a Customer Baggage Notification when a checked bag did not travel on your flight or arrived before you. Follow the message or use the delayed or damaged bag process.
American Airlines International Rules and Partner Airlines
International travel requires more than a passport. Check entry, transit, health, customs, and return rules for each country on the itinerary. Some countries require a visa or electronic authorization, proof of onward travel, a local address, sufficient funds, vaccination records, or a currency declaration.
American and border authorities collect passenger information for international screening. Enter your full name, date of birth, passport details, and other requested information exactly as shown on your documents.
International Travel Checklist
- Confirm passport validity and blank-page requirements for every destination and transit country.
- Apply for visas or electronic travel authorizations before the airline’s deadline.
- Check whether children need consent letters or proof of relationship.
- Review health, pet, medication, and customs rules.
- Arrive at least three hours early and allow more time at airports with earlier check-in cutoffs.
Flights Operated by Partner Airlines
American works with oneworld airlines and other partners, but earning miles and receiving status benefits depends on the marketing carrier, operating carrier, fare class, and route. Do not assume every partner ticket earns the same rewards.
Note: The operating airline may set the check-in location, baggage allowance, seat rules, pet policy, and onboard service. Check both your American confirmation and the operating carrier’s confirmation before departure.

Frequently Asked Questions
How early should I arrive for an American Airlines flight?
American recommends arriving at least two hours before a flight within the United States and at least three hours before a flight departing from an airport outside the United States. Add time for holidays, large airports, special assistance, pets, document checks, or airport-specific deadlines.
Can I use curbside check-in with American Airlines?
Curbside check-in is available for eligible domestic trips at many airports. You need a confirmed reservation, photo ID, and a credit or debit card for charges. A convenience fee starting at $4 per bag may apply in addition to normal checked-bag fees. Use the ticket counter when traveling with a pet, firearm, or unaccompanied minor.
When does American Airlines online check-in open and close?
Online and app check-in usually open 24 hours before departure. They normally close 45 minutes before a U.S. flight and 90 minutes before an international flight. Airport check-in and bag-drop deadlines are separate, and some airports require earlier check-in.
Are self-service kiosks available at every airport?
No. American offers kiosks at most airports, but availability and functions vary. You may still need the ticket counter for passport checks, pets, unaccompanied minors, special documents, firearms, or other services that require an agent.
What happens if I do not have a REAL ID?
You can use another TSA-accepted ID, such as a passport or permanent resident card. An adult without any acceptable ID may choose the $45 TSA ConfirmID process, but successful identity verification is not guaranteed and extra screening can cause long delays.
Can Basic Economy passengers bring a carry-on bag?
Yes. American allows one carry-on bag and one personal item in Basic Economy. The carry-on must meet the 22 x 14 x 9-inch limit, and the personal item must fit under the seat. Checked-bag fees and other Basic Economy restrictions still apply.
How can I avoid delays at airport check-in?
Check in when the 24-hour window opens, verify the passenger name and passport information, pay eligible bag fees online, keep documents easy to reach, review airport-specific cutoffs, and arrive earlier than the minimum. Go directly to an agent if your trip includes a pet, unaccompanied child, firearm, or document problem.
Which airline’s rules apply on a partner flight?
The operating airline usually controls airport check-in, boarding, aircraft service, pet acceptance, and many baggage procedures. Your ticket may still use American’s flight number, so check the operating carrier shown on the reservation and review both airlines’ rules.
Conclusion
A smooth American Airlines trip starts before airport day. Confirm your ID and international documents, check in as soon as the window opens, arrive with time to spare, and reach the gate before boarding ends. Review the exact fare, bag, child, pet, service-animal, and operating-carrier rules for your itinerary. These checks reduce surprises and make it easier to handle changes when they happen.
