After 6 months you get all the staff travel benifits.
Subload ( standy by ) on EK and zed/id 90 on OAL
CAT 99 ($99) plus taxes on EK is Y class confirmed if you can get a seat, these are prebooked on a very limited basis on selected sectors
EK will not and do not upgrade their own, so if you have a Y class subload ticket and Y is full and there is room in J too bad you dont go, but the friend of the check in staff at the staff counter in DXB always seems to get a seat on the flts that are always full.
