I am WL on a flight in business - Z fare code. It shows available on United.com, UA App, GDS (EF).
All show J9 C9 D3 Z1 ZN1 P0
Calling reservations the agents cannot see it and not confirm. Been like that for 3 days and I called twice
GS reservations > no luck.
Any way to get this confirmed?

(Mods please move to relevant thread, if appropriate. Thx!)
