GUP: Which fare bucket(s) determine Y to C GUP availability?
Hi there,
I'm looking to use one of my available GUP upgrades. The availability for one of the flights in question is:
F1 A1 P1 C7 D5 J1 Z0 Y3 B2 M0 H0 Q0 T0 K0 S0 V0 W0
So while eco looks sold out, C-Class has some availability (albeit at the higher end). While award class Z is out. Do GUPs only go through if there is availability in Z?
Cheers,
