All,
I have a roundtrip Business class ticket BCN-LHR-DEN in June and then a DEN-LHR-BCN return in September. I booked on AA but it is British Airways. I am Executive Platinum.
I may have to change the return date AND/OR not take the last leg as I now need to be in GLA in September now (few days earlier).
Looking for some feedback on strategy/approach.
Return is WAY out in future and BA is usually good at making changes to itenerary that allows for rebooking.
This is my current strategy.
Then when this happens, I would change the return to a few days earlier and then also not do last leg from LHR-BCN and would rather get a ticket from LHR to GLA when the change occurs.
The other way is to address now, but fares are more expensive than when I booked.

Questions: Is my current strategy sound? What happens if I do not take last leg from LHR to BCN with BA/AA?

Thank you in advance.
