Q. Are airlines able to change your flight without your permission? I purchased a ticket to fly out at 6 a.m. and the airline changed it to 4 p.m. If I had wanted to leave at 4 p.m., then I would have bought my ticket for that time.

A. Airlines state in their contracts of carriage that schedules are not guaranteed, but you can ask to cancel your booking and get a refund without penalty, even on a non-refundable fare, if they won't reseat you on the original flight you booked. That's also in their contracts of carriage.
