It's interesting that you raise this, because whilst the loss of a couple of Y fares won't bother them at all, I was originally supposed to go to Singapore via EK in Business, but upon finding out the proposed itinerary, asked if there were alternatives (this was about a year after the above flight and soon after I'd received EK's "we ain't bovvered" response). The alternative option was the direct A380 from LHR with Singapore Airlines (my first A380 flight).

If Emirates had sent a response that demonstrated they took the complaint seriously (as opposed to openly displaying the contempt they hold for customers), they would have got the proposed return business class fare from my company. Ultimately, I couldn't be sure that the service would be as advertised and couldn't guarantee that any failure of service would be dealt with by customer relations.
