I have done Z twice with short notice out of IAD
AND when I got on only 3 of 8 was full.
I think their revenue management sucks for awards
Same with EY
F6 on a 8 cabin 787 and no saver awards for partners even at 24 hrs!
Yeah, didn't want to risk it though. I have been stalking Z availability T-minus 3, 7 days for the Saturday AM flight and it has been inconsistent at best. Bit of a pain in the butt to fly up to BOS (and no Emirates car) but hey, at least we burned our EK miles.
