Skipness,
I actually worked at Gatwick for eight years and no, it's not a homework question. You're right, Easyjet has made quite an impact at the airport and i can remember when they first started flying from Gatwick and their growth there has been nothing short of huge. I still have a few friends who work at Gatwick and they do seem to talk an awful lot about the good old days when it had quite a bit of North Atlantic traffic and how the future looks bleak compared to then, and how great LHR is. Maybe they should go and work there. I think I'll take a trip down there again myself just to see for myself before deciding how bleak the future is. Sorry if I got anyones backs up. It wasn't my intention.
I'd still like to know a bit more about single runway operations and what Gatwick will do when it reaches saturation which can't be too far away. Also how many passengers and aircraft movements would mean saturation at Gatwick?
