I think with Emirates as they offer seat selection on their website to even non Skyward members thats why they get selected.

Also lots of great travel agents - go do you want a window or an aisle and request that.

its only the FT type people who really select what they want.

its also a by product of the fact that many airlines do not let u select a seat , so people who fly emirates appreciate the option and thats why they go early.
