It'll sound really, really sad that I know this, but it's part of my job. Honest!
2001 - 26L/R used 66% of the time

Lawyerboy,
Gatwick only uses the Northern runway when the Main (26L/08R) is closed, so we don't alternate like Heathrow.
They change from left to right (and vice versa) on westerlies at 1500 (L), not east to west.
Charley B,
Yup,
Virgin use B744's & a A343
European use B742's
and the rest of the big boys are B772/3, A330's.
