I cancelled a P class trip to Japan yesterday. I was offered a card refund minus the usual cancellation fee plus some extra fees which seemed kind of BS. My $3600 fare would have netted a refund of $2500.
I was rescheduling the trip to fall so I took the credit and spent it immediately.
The AC rebooking feature is broken as hell though. It would not let me rebook in business class, only Y (and it seems full fare Y because the ticket was only $17 cheaper), so I had to cancel and rebook. What I am curious is if I'd booked full fare, full refundable Y with my change, could I have gotten a full refund? I assume not.
