Actually, the B744 fleet is increasingly flying the bucket-and-spade routes from LGW - and was scheduled to be totally LGW-based by 2009 when the A380 was due to take the few remaining B744 LHR routes. That's all slipped sideways somewhat thanks to the A380 postponement, but if you were to get on the -400 by some chance you'd get very familiar with Florida and the Caribbean! A340 drivers can get 5 or 6 East coasts a month too - or a mix of 5 or 6 India/Dubai/Lagos/East coast flights with all that that implies for screwed-up body clocks! The old truism of "B744 = USA and short trips, A340 = Far East and long trips" is now out of date.
Right now, A340 destinations are: IAD (VS21 & (from April) VS55), JFK (VS3, 9 & 25), EWR (VS1 & 17), BOS, MIA (shared with B744), LAX (VS7 & 23), CPT, JNB (to the B744 for Dec/Jan), LOS, DXB, BOM, DEL, PVG, HKG and SYD. And NRT (thank you CHI!).
