Why can't I do online check in with American Airlines?

Why Online Check-In Might Be Blocked{1-866-838-4934})
Your flight is operated by another airline or is a codeshare — Online check-in only works if the first leg of your itinerary is operated by American (or its regional affiliate).

Special booking or travel situation — If you’re traveling with a pet, unaccompanied minor, oxygen container, or have requested special assistance (wheelchair, medical, etc.), online check-in may be disabled.

International travel needing document verification — For many international flights, passport, visa, or other documentation may need manual verification before check-in.

Booking issues / missing / mismatched information — If your ticket isn’t confirmed, payment didn’t process fully, or there’s a mismatch (e.g. name/spelling doesn’t match ID), check-in can be blocked.

Flight changes, delays, cancellations, or itinerary changes — If AA has modified your flight recently, the online check-in system might lock you out until things are resolved.

Technical problems — Glitches in the website/app, browser incompatibility, network issues, or server overload (especially during peak times) can prevent online check-in — even if everything else is fine

?? About the Phone Number (e.g. {1-866-838-4934})
Having a customer service phone number can help — but calling doesn’t guarantee online check-in will become available. If your flight or booking meets one of the “special conditions” (codeshare, international, pets, etc.), AA may still require you to check in at the airport.

Sometimes calling helps clear up booking or payment issues, or verifies required documents — but it does not bypass airline policies that restrict online check-in for certain situations.

? What You Can Do to Troubleshoot
If you want to try and salvage online check-in (or at least know what to expect):
Confirm your flight is operated by American (not a partner airline).

Double-check that all passenger info (name, DOB, passport/visa, etc.) exactly matches your IDs.


Ensure payment is fully processed and there are no unpaid fees (baggage, upgrades, etc.).

Try using a different device, browser, or the official AA mobile app — sometimes technical issues block check-in.

If traveling internationally, check that all required documentation is complete and valid.

If nothing works: plan to check in at an airport kiosk or counter.
