There was no chance for me to choose a seat even if I were willing to pay extra for it when I was doing the check-in on line. My seats were the last row on the plane and they didn't have enough food to give me. I had to eat what was left after everybody else had their choice of food. This is unacceptable. Everyone should have a choice. I paid money just like everybody else. Never had this happened on any other airlines even if my seats were last row on the plane.
