They changed our flight without permission and we were forced to catch a Delta flight there so as to not miss our plans. We had to pay triple the amount due to their negligence and oversight. I also contacted their corporate and they refused to refund us partially for the first missed flight. They refused to refund us for anything. We will never fly Frontier again. Only Delta. We also weren’t the only ones on the plane saying this. Several customers were treated so badly and will not fly with this company again. That is how you know Frontier is awful, when everyone has a complaint.

Paid for the seat package upgrade that also included a free carry-on bag. Then when I checked the reservation later there was no carry-on bag included. call customer service and they said I didn't get that package when I did select that package. So I had to pay 128.00 more to get a carry-on bag included when I had already paid for that with the seat package.
