United flys direct IAD and is full everyday...I've sucessfully ID90'd them once and the in the back its full of our kind of customers, EK would decimate them on that sector.
Delta to ATL is similar, I've been told.
Just an observation...EK dispatch if they are planning to go to ORD had better be less conservative in their winter flight planning then what I've seen out of them this week to JFK. (I can't speak of YYZ). Farthest alternate then say 30 mins extra holding is sufficent enough for an international arrival into ORD, JFK, IAD. If we're serious on a North America expansion then get used to the snow and ice, airports there won't close for a few inches and don't institute the same sort of panic planning that is the norm (and required) of the UK airports when there is flakes in the air.
my two dhs...
