It's an interesting question because for EK to honour ALL QF staff entitlements would mean them granting travel benefits to QF staff which their own are not entitled to...
e.g. in QF any flight/cabin crew who does not automatically get J class INT travel gets it after 7 years of service regardless of if they are the equivalent of a GR2.
They can also bring friends/boyfriends/girlfriends/same sex/defacto partners, something which is definitely not allowed at EK. You want your gf to travel with you, she has to pay her own way...
QF staff can avail space available J class if they buy the correct staff tickets- EK staff cannot unless they are FO, Purser or other higher grades.
*IF* EK honoured ALL QF agreements, I can see a lot of seriously p!ssed off employees... and fair enough, if they can't get it on their own airline the why should OAL staff??
My siblings can't even get QF or JQ tickets, yet my friends in QF can happily bring their mates.... doesn't exactly seem fair does it?
