Emirates have agreed not to sell any more seats out of LHR so if I want to book a flight with them to Far East via DXB I and forced to use STN or LGW. Once flights are on sale again from LHR I have that choice now. If this capacity cap at LHR continues then I can see x2 STN soon.
If STN catchment is the only factor and that is strong why not do x2 now to get double win?
