I recently booked and purchased a premium economy ticket on Qantas. I booked PE because of a previous Qantas PE flight which was excellent. The ticket was purchased and paid for well in advance and now Qantas have downgraded my seat and ticket to economy due to a change of plane. I have no issue with the change of plane but I do have an issue with the fact that I booked PE not economy. Now that the flight date is closer there are no other comparable flight deals with other airlines ( as I would happily take a refund and go else where) and to add insult to injury Qantas has not offered to refund the cost difference between PE and economy or offered any other sweetener to take the bad taste away from being duped into paying for a PE seat and then being given economy. Does this happen often and what, if any, recourse an you get?
