It's true that there's some J availability in Nov for JFK-DOH, but no seats are being released in the last few days (i.e. for Dec).

Further, I'd rather travel EY than have to change planes in JFK; and indeed I have the option to do so. I would also fly CX but that option is gone.

The more general question is why QR J availability switches on and off like this. It's not the first time. What are they trying to achieve? From ORD they had abundant availability in Nov, and then it vanished suddenly...it can't have all been booked one day, it was just withdrawn. Yet it isn't all flights---Oct remains widely available for ORD-DOH.
