Has anyone been able to book JFK-YVR for the next month until January 1, 2019? I've been looking to buy a Y ticket but CX seems to be blocking all classes. F0 J0 D0 etc. I just flew J in this on an award ticket I booked back in August and there were maybe 8 people in business class so it seems that overbooking isn't the reason here.

Does anyone know what's up with this?
