Don't be too harsh wiz, no one ever explained loads versus yield to don. Better hope all those premium seats are sold full-fare. I mean, EK never oversells US flights, with all the attendant upgrades into J and F....dooooo theyyyyy? It's pure profit, baby. Fuel's cheap, after all. Pffft. hahah!
The seats argument makes sense in slot-constrained airports like Heathrow or Toronto. Anywhere else would gladly see multiple "twin" flights with "three class configuration" and, oh yeah, 20 tons of cargo a flight. But that's just from the station managers trying to move pax and cargo, what do they know.
LAX is about ego. It hurt too much to see everyone else running their 380's there so EK had to do so, being the launch/biggest/mostest/whatever ad nauseum customer.
Then quietly add a B777 flight later to pick up the slack. I expect that pattern will repeat.
