This might be a daft question for the seasoned travelers but I could use some advice. I am not sure if this is possible. I bought 2 tickets in premium economy for a trip to Italy on American Airlines. Today the price for the same tickets are $800 a ticket cheaper. Is it possible to rebook and get the price difference in a flight credit? I know I won't get a refund because the tickets are non refundable. If it is possible can you advice me on the process rebooking? Would I need to cancel my original reservation and repurchase?
