I am active on the private server Fokker. Short / Medium haul First class demand has reduced a lot in the past few days in the server. Loads have gone from 90% to 20%. Similar pattern with competitor’s airlines as well!
Were there any background updates on demand across classes?
Besides any changes in general demand caused by the recent data patch, almost certainly not. Especially not specific to particular service classes and/or flight distances.
The drop is observed in other routes like CAN to BKK, SIN, NRT, KUL, etc. Domestic routes within China has a moderate drop as well. Only one other airline offers F in China and I can see from Market Analysis that his flights are empty as well:
