I was originally scheduled on AA 1763. When I landed in Miami, I went to the counter for flight AA 2115 to try to move my flight to this one. I was in a first class seat on AA 1763. While they moved to me this flight, I was told that there were no other 1st class seats available and they assigned me into coach. However, when I was getting off the plane I noticed that one of the pilots who was also in line to go jump seat - somehow miraculously got a 1st class seat on this flight. It is actually infuriating that I had a paid 1st class seat yet somehow they would move an AA employee ahead of that. At a bare minimum, they should have compensated me for the fare difference and I really think paying customers should ALWAYs get the premiere seats.

So excited very proud first of all I wanna thank kayak all updates very professional and fast alart And amazing cabin crew so nice to me they deserve big salute

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

We experienced gate changes and a long delay. My seat was dirty when I boarded and I had to use wipes to clean it myself. There was an unpleasant and overpowering cleaning product scent on the plane as well that lingered through the flight.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

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.

The flight was on time and arrived early. The crew were friendly and helpful.

We had a 2 hour delay that impacted our comanions further travel. I have a feeling AA knows there is a problem at the Cabo airport and does not account for that.
