We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

it was a very short flight so my expectations were low.

As great a red-eye flight as red-eye flights can be.

Arrived early picked up my bag in a few minutes- great trip - thank you

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

Flight to Tampa was delayed taking off due to plane arriving late but no other issues

There was a delay with the plan which cause the flight to leave later and once arrived in Chicago there was another delay and some passengers missed their connecting flights

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

Worst experience ever. Flight could not land in Charlotte for what we were told was a ground stop. Had to be diverted to Raleigh to refuel. Strangely during ground stop, our connecting flight had no issue taking off on time causing us to miss our flight. We were told there were no other flights that day to our final destination and that two days out was the next one. The only flights to get us there were from Chicago the next morning. Completely opposite direction but it was a direct flight. So we get flown to Chicago and have to find a hotel in our own dime. The flight in the morning was also delayed. Thankfully only a short time. The non too of all this, our luggage did not arrive by the time we were there. Communication was terrible, through the entire trip. Complete incompetence. Will never fly American again.

I am an AA flyer for a very long time... AA has yet to disappoint.

Flight was delayed. Not much information on when the flight would take off. Eventually we were told it was maintenance. App was not giving updates.

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