Okay, wise MPers, who should I complain to about this? Flew Ethiopian ET500 on November 10th in Biz class (ADD-IAD) on a ticket booked with United miles. About an hour into the flight, my seat controls stopped working and the seat was stuck in a partial recline. The seat could only be put upright or laid flat manually by the crew who were none too happy about the chore and reluctant to help. They eventually laid the seat completely flat and left it. I had to eat dinner sitting cross-legged on top of the flat seat. There was a crew change in Rome and the new crew was even less helpful. I asked several times for help with the seat and even showed the flight attendants where the manual controls are located. They insisted they couldn't manually adjust the seat and didn't attempt to put the seat upright until towards the end of the flight and the best they could do was a reclined position. Sitting on top of the flat seat was uncomfortable and the crew was begrudging. (I understand Amharic so I know just how begrudging they were!) But who should I complain to since it was an Ethiopian flight booked with United miles?
