Sorry to ask a question that is probably easy to answer for a lot of flyer talk members, but I purchased 3 tickets for my friend and her sister on my credit card to Iceland for a trip we can’t take. How does the voucher work? Do we all have to travel again at the same time, or can we travel at different times using the voucher identification number? I haven’t applied for the voucher yet as our flight is in September but just want to make sure I understand the process correctly. Thanks for any help and information.
