Mechanical issue delayed us 2hrs and then once we landed sat on tarmac for 30mins because someone left a vehicle in front of the gaye

The crew was excellent and overall the flight was good. No complaints.

Like all of the flights I took to get down to Dallas. They were delayed

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

Flight pulled out on time but sat on runway for 30 mins. It was extremely cold in the aircraft despite wearing a winter coat. Surprisingly they had a vegetarian meal but could have some better snack choices for a 8 hour flight.

We had a male flight attendant who was super attentive and wonderful! Very professional. I have both gluten and dairy intolerance, and was only able to get a gluten free part, and not the dairy free part of the meal. Easy to order ahead of time and I appreciate being able to do that.

It was a train wreck but on an airplane. First off, flight was delayed then we board only to hear two announcements, First weather delays in Orlando and second backup battery warning on emergency lights. After sitting on the plane for almost 2 hours they have us deplane due to the maintenance issue. We were told they were getting another plane. In the mean time, I notice another American- Orlando flight and ask the gate agent if I can switch. He says he cant help me and I'd have to walk to A13 from A37. Really!? I get down there and get a seat only to get an announcement my original flight was RE-boarding. The Then inflight there's no communication and I notice on flightaware were circling over the Gulf of America. I call the flight attendant and of course she has no clue and apparently 5m later the pilot finally tells us about another delay. Why does American always have these service and delay issues? They are my LAST choice in flights now!

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

Never ontime and always delays. Long waits for customer service and often app doesn’t work

We arrived 25 minutes early only to be told our gate was occupied and so we sat for close to 30 minutes to pull into a gate. That’s not an early arrival!
