From what has been reported, Air NZ and QF have been refusing to deal with EK (or at least not giving terms EK can accept) with respect to lounge use for EK pax.
Gotta love EK's strategy - if you won't deal with us, we'll just build our own damn lounge. A poke in the eye for the other airlines, if their CHC lounge is anything like the ones in their other outports.
