On time on a day with lots of weather cancellations on other flights. Thank you for getting me home during a winter storm!

Don't change gate multiple times make people run across the airport. Announce delays in a timely manner. Have maintenance crew ready. Don't delay and keep passengers on the plane for 3 hrs. on tarmac.

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

Little warm on the plane and delayed for an hour

UGH I HAD TO MISS MY FIRST FLIGHT TO TAMPA CAUSE OF THE 10 MINUTE DELAY OF THE ORLANDO TO MIAMI ONE SO THEY HAD ME GET ANOTHER TICKET. I AM NOT HAPPY AT ALL BECAUSE IT MADE ME MISS MY CONNECTING FLIGHT FROM TAMPA TO LONDON AND FORCED ME TO MISS A DAY AT MY ROOM IN THE UK.

Wish they didnt delay off-boarding for 10 minutes so i could connect to my flight from miami to tampa

It was fine. My connection in Charlotte to go to WPB was too late and I had to spend the night in the Charlotte Airport in the mini suites.

Boarding was organized and timely. Food was mediocre, especially for first class travel.

We were 4+ hours delayed. AA is absolutely obnoxious. They just kept pushing back the time to the point where we did not get into Vegas until after midnight when we were supposed to arrive like 845pm.

My last flight on 25 Dec, it’s Christmas Day, everyone happy and very good mood. I really enjoy traveling with Americans Airlines from Miami to Minneapolis my home town after long flight from lhe to Doha then Miami. Thank you again to make my travels comfortable and relaxed. Best regards
