I can't figure out this one. 1/11/2020 UA 1175 SFO-HNL (It is now 12 hours before departure). Flight Status shows FC available, 9 people already upgraded since D-24 as shown on the upgrade list, but 28 seats FC have 33 booked.
Standby page says seats available
capacity 28 seats (777-200HD), booked 33, 10 upgraded at D-24
