TOD upgrades (Y->J) seem broken on 3-class flight
A couple of friends are booked on UA900 tomorrow (Thursday 8 June) in Y.
On the upgrade screen in the app, it shows UA900 as "sold out", however there are 16 unsold seats as per the upgrade screen on the flight status page.
F is however sold out.
Is it possible that it's reading the wrong fare class? The flight is showing R9 when you go to book.
