Upgrading flight purchased at a travel agency
Hello There,
Does any of you know whether I can upgrade a flight purchased at a travel agency using an evoucher? If so, does the travel agent have to do the upgrade for me or can I do it via the internet?
By the way, can a Z fare on MUC/FRA-TLV be upgraded to F class using evouchers (or you can only upgrade ticket purchased in D fare?).
THX in advance!
