The 330 did pick up Dublin and Saigon and even a bit of Hong Kong, so maybe EK is trying to even things out a bit.
They don't do equipment assignment based on being nice to Pilots. Most new destinations go to the 'Bus because it's the smallest.
When they build up enough traffic to justify it, they go to the 777 (we pick up Prague next month and Dublin in October).
Of coures, then WE lose the prime routes to the Dugong after a while...
