Looks like I will have to cancel my BUD-CDG-SFO-AUS tickets for September. Have paper tickets issued by expedia.com and will have to send the tickets back to them. My understanding is that I will 'only' lose the paper ticket fee that expedia charged. Anyone have any experience with this or would it be best to attempt a refund directly with AF? If a full refund is not possible I will try to change dates instead...
