I have an award ticket booked with UA with the following segments:
EWR - GVA UA
GVA - FRA LH
FRA - BKK TG in F
I have an additional ticket on hold:
JFK - FRA lh in F
I would like to substitute the first two segments of the first reservation with the second reservation, but UA reps say that it's not possible without canceling my reservation.
If I cancel my reservation LH I'm afraid that the tickets may not reappear. The same goes with my TG reservation.
Any ideas?
