The people I was next too were a family and they made the flight miserable with their endless complaints and lack of respect; the airline refused to move me to or to give me the seat I needed for my medical condition. The food has never been good and the entertainment is trash. I took this flight based on the fact that it was a last minute booking so I could afford it…
