Movies on my phone are great. It would be nice to have a gluten free snack option.

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

The airplane was an old model, the overhead didn’t have enough room for people’s items and made boarding and boarding disappointing and stressful. Crew allowed passengers to bring more than the permitted baggage sizes.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

I almost missed my flight and they helped me out enormously

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Moved to earlier flight which unexpectedly had maintenance issues initially indicated as quick fix to ultimately plane changes. Moved back to original flight, also delayed. In all cases customer updates and communication very unclear, no updates on drivers for delays.

Typical AA - late by 90+ mn. Gate changed twice... Changed the departure time 6 times No explanation, no communication on reasons for delay I travel with AA twice a year... and it is consistently very poor.. I will continue to use AA only when i have to.

Pretty awful. 2 hours late due to operational issues and finally deboarded around 2am.

The gate got changed several times and the flight was delayed over an hour. Awful experience
