EK just want to be able to offer an around the world fare with QF flying the AU-US leg. That's all. QF is about to introduce EK to AA so that EK could help AA through restructuring and in return EK gets a North & Central American feeder service. So QF & JQ can fly a PAX within Asia & South Pacific, AA through North & Central America and EK through ME & Europe. Only having to work with 3 airlines make for a nice little RTW product.
Hence the discussion around the prospect of EK & QF co-ordinating efforts out of DFW & LAX.
