I'm not sure that necessarily holds at all - EK operates only A380s to LHR and I'm fairly sure if they could pick up some more slots cheaply to add more service frequency they wouldn't say no. CX and QR both recently started flying from LGW again partly because they'd both like more LHR slots but can't get any. SQ I'm not sure about but I'm sceptical they'd refuse the chance to add another LHR rotation also. It's only really BA on that list that wants a standstill on LHR growth.
