We bought two tickets from DC to XNA (Northwest Arkansas) departure Oct. 6 return Oct. 10. The basic economy fare was already very high ($490 per person roundtrip). This was last Spring. Recently we had to change the return date due to unforeseen new obligations. We had to pay $200 per person penalty fee plus the difference in fare which by now had risen to $767 (basic economy DC to Arkansas)! On departure day and after check-in we were notified that our flight was cancelled. We asked for a refund. They processed the refund but ONLY for the airfare (not for the penalty fee). We contacted them and their response was that since we paid an economical (!) fare they could not do that. Putting aside the predatory airfare AND the stiff change fee there is a legitimate question about them keeping the $400. The product they sold that included this fee was cancelled. So why must we still be robbed of this amount?
