Booked a trip CDG-ORD-LAX-SYD-SFO-FRA-CDG for which I got all my upgrades confirmed except the ORD-LAX leg.
When I access my itineraries on UAL.com everything shows up however when I want to access the seating map only the Y-class cabin shows up on all sectors and i consequently cannot change my seat assignment in case a better seat becomes available. Anyone knows how to deal with the problem?
Thanks for the input
