Does that mean that once an original ticket is canceled and a flight credit issued, then you rebook using that flight credit (partially or in full/with extra payment) and cannot make further reservations (3rd, 4th), and funds from the original ticket will be lost? Or, is it only relates to OP`s situation when trying to use both Flight Credit and the leftover from the original flight credit i.e. voucher?
