How to Check In Online for Your American Airlines Flight

Checking in online saves you time, avoids airport lines, and ensures your boarding pass is ready before you reach the terminal.
Here’s a simple, step-by-step guide on how to check in online for your American Airlines flight — through the website or the mobile app.

Step 1: Know When Check-In Opens

You can check in online 24 hours before your scheduled flight (domestic and international).
Check-in closes 45 minutes before domestic and 90 minutes before international flights.

✅ Set a reminder so you don’t miss it — checking in early often means better seat options.

Step 2: Visit aa.com or Open the AA App

• Go to aa.com/check-in or

• Open the American Airlines mobile app (iOS or Android).

You’ll see the check-in form right on the home screen.

Step 3: Enter Your Booking Details

You can check in using any of these:

• Booking reference (PNR) + last name, or

• AAdvantage account login

Then click Check In to access your flight.

Step 4: Review Your Flight & Select Your Seat

You’ll see your flight itinerary, seat, and baggage info.
If you didn’t choose a seat during booking, you can select one now — some seats may cost extra.

💡 Tip: Always confirm your seat before completing check-in to avoid automatic assignments.

Step 5: Get Your Mobile Boarding Pass

After check-in, choose how to receive your boarding pass:

• Download to your phone (Apple Wallet or Google Pay)

• Receive by email or SMS

• Print it yourself if you prefer a paper copy

✅ Keep the QR code ready at security and boarding.

Step 6: Add Baggage (if needed)

If you have bags to check:

• Pay for them online during check-in, and

• Drop them off at the AA Baggage Drop counter at the airport.

This saves time and gets you a priority lane if available.

Step 7: Head to the Airport

With your mobile boarding pass ready, you can go straight to security if you don’t have checked bags.
Otherwise, use the self-tag kiosks to print bag tags quickly.

Quick Tips for Smooth Check-In

1. Use Wi-Fi or data when checking in through the app.

2. Verify passport details for international flights.

3. Print a backup copy of your boarding pass if you’re worried about battery life.

4. Check seat upgrades — sometimes AA offers discounted upgrades during check-in.

Final Thoughts

Checking in online with American Airlines takes just a few minutes and can save you a lot of airport stress.
Use the AA app or website, secure your seat, add bags, and you’re ready to fly!
