Looks like Aviator will have to 'get rid' of a few airlines, currently they have an enormous share of LGW with BA, Virgin, Thomson, Thomas Cook & Norwegian.
Cannot see how that can be allowed to continue, with all the major scheduled and charter/holiday airlines at LGW except easyJet and Emirates with the same GHA, unlikely to remain for long!
Or maybe cynically, Swissport knew this situation would arise, and are ready to buy back some airlines!
