So I booked my flight through my travel agent about 5 months ago. Turns out I got 3 extra nights and need to postpone my return flight to 3 days later. Our trip in end of may to beginning of June. She is telling me that to change the retunring flight it will cost $200-$250 PER TICKET! Thats insane!! I checked mexicana and I could buy a whole new ticket for $250!! Makes no sense. What do you guys think? HOw much does it usually cost to change? I was thinking of canceling the whole flight then rebooking it for the $250, and in the end paying the same I paid in the beginning which was $470. I feel ripped off. =( Any ideas how much it costs to change or cancel?
