Flight delay and took forget to lift off.
I was truly shocked at how poor this flight went. The crew was not friendly during the checking process. The asked for people to gate check and were rude about it. They didn't handle my luggage with care. When I got to my seat I noticed a large section of the ceiling vent area was, no joke, TAPED TOGETHER WITH CLEAR PACKING TAPE! To add insult to injury, the back rest button was disabled on my seat and all the seats I could see. The wifi, never connected for me, despite troubleshooting it for a while. I did everything from restarting my wifi/phone to forgetting the network and restarting the app. But that didn't stop the mandatory 2 ads from playing every single time. Even the bags took over 45 mins to arrive at the carousel. Everything about this flight was a flop and I am beginning to notice that some of these events are becoming a trend. Perhaps it's time I switch loyalty programs.
Had to find alternative flights because of AA lateness and bad planning
Fliy was late missed my connection ,. I had to find altery transportation.
Horrible airline, will never buy another ticket with the airline or Kayak. They close the gate 2 hours early in Kenya, I had to buy a new ticket and get a hotel room
The close the gate two hours early so I was not able to board in Kenya. How do you close the gate two hours early?
Exceptional service
No food
When we landed, there was only one gate agent to handle three planes, including retrieval of carry on luggage. I was stuck in the jet way waiting on my carry on for almost 20-30 minutes. NOT GOOD
The flight was overbooked. And the gate agent basically said that the flight will not leave unless two people came forward to give up their seats. Offered money. Raised the $$ too. But we were there for a while and flight was delayed. When passengers approached the gate agent asking what would happen if no one volunteered- the answer was flight would be cancelled! Ridiculous! It’s American’s fault for overbooking. The service level is going from Bad to worse it seems.
