You owe me a flight. This trip was canceled and I got to the airport just to find out. Cheapflights did not book me another flight and left me hanging at the airport. I had to purchase a new ticket for double the price because of your company. What a shame and if nothing gets resolved I am going to file a lawsuit to get my compensation.
