Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

2+hrs delay without any reason provided and a cramped flight

We waited an hour on the runway to get a gate in Orlando

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Flight was delayed due to crew being not on time

Flight crew issues delayed my flight by 2 1/2 hours. Causing me to miss my connection.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

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.

Flight was on time and there was an empty seat next to me. That makes for a good flight!

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.

Everything was good. Flight was very full so crew was busy. After we boarded and plane pulled away from the gate, we were delayed about 40 minutes- sitting on the runway - due to weather en route or at the destination. While weather is not the fault of the airline- it’s terrible to sit on a plane and not moving.

The flight was on time/early, attentive crew, and everything overall went smoothly. Disappointed that WIFI was not working for the flight.

I got sick nothing contagious but distressing enough and the care I received on the flight was astounding.

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

Initial flight was cancelled at the time of arrival to the airport, flight alternative requires switching from direct to flight with a layover, and the plane felt like it would split apart, it was so rattle-y.
