However it will probably be easiest to talk to the issuing airline.
If I convert a layover into a stopover, does that require a reissue? Specifically, if I have SYD-NRT-KUL as the first set of flights, but I want to fly SYD-NRT "right now" and leave NRT-KUL and all the onwards flights unchanged; can I just move SYD-NRT to "next week" while leaving the rest of the ticket to later in the year? Do not plan on changing carriers or anything else.
