Looking for some advice to help my in laws out on ticket validity, that I've never been 100% on.
I want to book my brother in law a return ticket - MEL-SIN-ZRH, ZRH-SIN-MEL on SQ Y. He's got a relatively fixed date to return to ZRH, but isnt 100% sure on his return date (approx early April 2023), but definitely will be returning to MEL.
I assume I'm best to book this as two seperate awards unless told otherwise.
If we need to change his return date, and provided we dont change routing/airline - the ticket remains valid for 12months from booking date is my understanding, and provided the same availability is available on the new date inside that 12month period - do we only pay a change fee?
Eg. Book for ZRH-SIN-MEL on SQ Y on say, April 10 - my understanding is that if we change it to April 17 (or any other day), there is no ticket re-issue and/or taxes payable and/or points payable?
Given there is only 1 flight from ZRH-SIN on SQ daily, its no issue - but does he need to be on the same flight number on the changed date for SIN-MEL?
I know this has been asked before, but want to make sure before booking for him and the 5 July enhancement to points table.
