I know this is a question that's been asked before, but I'm still not sure I'm clear. If my fare goes down, I have to call the refund dept. and they will actually issue me a refund on my credit card? Will they do it right then, or do I have to wait til I return from my trip? And will they only give you the refund if it's for the same flight originally booked? And if I change flights for one that is less, do I only get a voucher? Thanks for explaining this.
