The seat when "flat" was not flat and pad was too thin to cover it.

The seat when "flat" was not flat and pad was too thin to cover it.

Delayed for mechanical and no updates on what was happening and how long the delay might be.

We are too tired and frustrated to comment politely at this point

My flight was delayed for several hours. Sitting at gate 16 for several hours, I got a text from Kayak the gate changed to 9 before it was announced. Very bad communication at each gate from American Airlines employees. I received 10 notifications of delay from Kayak. My vacation started off horrible! I will write to American Airlines corporate office also.

The service and food needs to improve to catch up with other international flights

The flight crew was fantastic! Which the seats had a small TV.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

This time my flight was smooth and uneventful. They started boarding even earlier than it was scheduled. I was pleasantly surprised. Thank you!

Boarding was a mess - the agent basically called every group in rapid succession, so there was no organization at all. The economy seats are a joke, and main cabin extra seats were sold out when I purchased my flight. As such, I was locked in the same position for four hours. Being 6’6”, it was impossible to get my bag out from under the seat in front of me, and I couldn’t have used my laptop even if my bag were accessible due to the minuscule seat pitch. Also the wifi was broken. American is a joke - can’t wait until they merge with Spirit.
