I feel cheated by American Airlines - actually a stronger word comes to mind. I bought roundtrip tickets for my wife and I last October to fly from Houston to Liberia, Costa Rica with the understanding that:
"Tickets are nonrefundable and nontransferable. A fee of $200.00 per ticket is charged for itinerary changes. Name changes are not allowed."
We decided to stay longer in Costa Rica so I called AA in December and was told we could use the unused portion of our tickets, less the $200 change fee on "any future AA flights as long as travel is completed within one year of the issue date"
So today I tried to make roundtrip reservations from San Jose, Costa Rica to Houston, and was told that we could only use the unused portion of our previous tickets on a one-way ticket - not a roundtrip. After deducting the $200 change fee and repricing as two one-way tickets, the total fare is actually $300 per person higher!
At no point in the information I was provided when I bought the ticket or the phone call in December was this restriction mentioned. Perhaps it is a new rule.
The final result? I booked a cheaper roundtrip ticket on United, and American Airlines gained an "enemy for life".
