It was not good. As soon as we entered the plane, 2 girls in front of us bend their seats down completely and startes sleeping within the next 2 minutes. I asked one of the air hostess to ask the girls to make them sit straight because we just entered the plane and we wanted to sit properly put our seat belts etc. The air hostess replied to me in the EK 009 plane that it's her right she can bend it but when we take off, she will have to straighten her seat. She never did because the air hostess never told her. The girls left their seats bent down and I had to intervene to ask them to straighten their seats because we had to eat. The girls kept telling us to please eat fast so they can bend down. What rubbish is this. Pressure to eat for their comfort and our discomfort.
