list is endless
LBA
EMA
MMA
and i could see WOW looking to operate all of those, but more than likely into LGW where slots are could well be easier to obtain and the onward connections are better which im guessing would be a good source of traffic ?
i doubt wow would ever be able to get slots at LHR and if they did im sure that NQY/PLH would get them ahead of any others
just my opinion anyway!
