Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.

British Airways is an excellent airline. Comfort, food and airline personnel.

We changed our flight because of weather. Unfortunately we were on hold for over an hour, but since we were 5 people who all booked individually, we felt more comfortable doing it with an agent. It all worked out in the end.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

Older airplane with worn out seats. No entertainment system at all. Connecting to Wi-Fi was problematic and hit and miss.

I didn't end up taking this flight. I got up at 4am for a flight that was supposed to board at 6am - at 5:55am you delayed the flight to 10am. The airport is under construction so I switched to a later flight as I wasn't going to sit in the airport for 4 hours. They said the delay was due to the crew needing rest from a flight coming in late the night before - if that was the case then I think you should have delayed the flight much sooner so that passengers wouldn't get up so early and get to the airport to sit and wait.

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

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?
