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.
