Joker modification flexibility
Hi all,
Coming to the end of my membership year and keen to preserve some jokers. Will preemptively issue tickets to modify later. Two questions based on this:
1) If I issue as a one way, can I always (within ticket validity) modify this + add a return?
2) Am I able to change the origin as well? E.g. If I book LHR-AMS but then change to NYC-LHR--is this possible or any watch outs?
Keen to tie up least amount of avios but preserve max flex...
