Virgin_cc_wannabe you answered your own question. The 777-200 runway figures were googled and the runway lengths were from an RAF en route supplement.
The point I was trying to make was all these airports are capable of landing a 777 at MLW but only DSA/EMA could cope with a MTOW departure.
Given they are not intending to go to max range (Canada) they probably dont need max fuel. If they have a reasonable baggage allowance and don't configure the ac in pack em in mode like the PIA A310s ie 2 class then I would expect all with maybe the exception of BRS could be doable with a profitable load. Things aren't just black and white you know!
