The service was absolutely terrible, check-in had a line that wrapped around the corner, that took about an hour and a half, boarding began late, our plane was scheduled to depart at 5:10 we didn’t depart till 5:50. The service on the plane was absolutely terrible as well. They had no cabin wifi as advertised, no amenities as in drinks or food/snacks. Only to buy, for a 9 hour international flight! I don’t know how or why American Airlines chose to be partnered with this airline. Wouldn’t it make sense to partner with airlines that provide the same care for their customers/guest? Never again.

I liked watching TV on the AA app. I didn’t like that the flight attendant assumed MY bag was the one that overcrowded the overhead bin and took it up front. I understand a crying baby but when it’s excessive, maybe the flight attendant can offer some assistance to the family to calm the baby down or help them in general and remind the family that there are other passengers on board
