More evidence of LGW being LHR's waiting room (as far as long haul is concerned).

The above article states that their is a long list of airlines who want to use to Heathrow but can't due to capacity constraints.
Assuming that this list includes all the current operators who use Gatwick but not Heathrow (easyJet, Garuda, Ukraine International, Air Baltic etc) I have to admit I'm struggling to come up with that many others.
For me the obvious contenders are LAN Airlines, their various offshoots and Aerolineas Argentinas. Would China Airlines want to have another go? Would Air Namibia do any better at Heathrow? What about airlines such as Xiamen which are planning on going long haul?
