wanting to know if I can "extend" my GPU to cover the last segment on LH?
Route is TPA-EWR-MUC-IST. All UA metal until MUC-IST, which is on LH.

GPU is already applied and the upgrade cleared.
Fare Class is V for segments.
All connections are <4 hrs.

I'm guessing the answer is no, but if anyone can do it, it will be an FTer.
