FYI, I've been keeping an eye on QR763 (DOH to YUL), as I will be taking this flight later in Feb, and as of Jan 29, they are again flying over Iran and not Iraq as they have been recently doing.

Did a quick search of other flights originating out of the USA and it appears that those flights are still flying over Iraq, however I see that flights out of Nth Europe (ARN) are also flying over Iran again.
