Great flight with a terrific crew. Uneventful and early arrival. Thank you.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Clean planes and not take my comfort class seat away.

Weather caused a long delay, but the efficiency and updates from the pilot were helpful. We were able to make our connection fortunately.

Flight was delayed. Then eventually cancelled. The female staff that was announcing overhead was unprofessional. She was telling everyone that the company is not going to give any money for taxi, hotel etc. then eventually the flight was cancelled.

My service light was on 15 minutes before I had to get up and find a glass of ice. And I was in business class. The meals were not for either my wife and I. She did not eat the entire 10 hour flight and I managed a bowl of soup. I was expecting much more from business with what we paid.

Planes were clean, no water or snacks on either flight.

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

They made nearly everyone check their bag because the overhead bins are way too small. Extremely inconvenient

The overhead bins are too small, They served one meal and two snack for a 10hr flight. My meal was missing the butter, cheese and salad dressing everyone else got. The crew were nice and the plane was clean

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

The passport line was so long that many of us were concerned about missing our flight and some did. It would've helped if a AA representative had gone to the passport check-in sooner to advise that boarding was closing and those flying that were stuck back in the line, needed to come forward with apologies to others. An AA representative did do that but only after boarding had already closed. (They delayed take-off so that more who were running with carry-ons could get to the gate - especially stressful for older people!) Then to be crammed into a seat with barely enough leg room for a thin woman, 5'7", like me, much less for a taller, bigger person was not comfortable, especially if the person in front decided to lean back. Crew was fine, food and entertainment also.

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

It was what i expected. I like the movies you can access from your phone. It would be nice if there was a gluten free snack offered. But I did bring my own snack knowing there would not be a gluten free option

The flight was peaceful, just s slight turbulence, pilots and crews were all nice and made a great job! Arrived safely in the Philippines. Thank you ya’ll!

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

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.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.
