I think Stansted would be nearer the bottom of their list. Currently I think an unofficial list of top 3 would be LTN, EDI and DUB with the latter being the more likely.
I like how EK nearly always seem to start a route with the A330, dependant on the range etc. and then build it up. MAN started with 3x weekly A310 and now has twice daily 77Ws.
I'm not trying to rub it in to BRS users
but I am just saying that EK seem to know what they are doing and it is a shame that unless the runway is extended and EK make a large expansion in the UK, it will probably never grace the slippery runway down in the South West...
