If I have AUH-JFK in J, aside from mileage differences, would I pay a change fee for each of these scenarios? In all cases, the dates and origin/destination airports are remaining the same:
1. AUH-JFK in F [cabin change on non-oneworld member]
2. AUH-LHR-JFK in J [with BA for LHR-JFK, and still valid routing I believe]
3. AUH-LHR-JFK in F [same as above, but different cabin]
I am not an EXP, and the departure date is over six months away.
Feedback appreciated.
