Is the Virgin hangar at LGW closed permanently now? What about the North Terminal Clubhouse? Has it been stripped out for re-use yet?
LGW could well be cheaper to operate from for some of the Beach Fleet routes but the core clientele that make the money like their lounges and Virgin experience, so the Clubhouse would likely need some proper re-investment. It may also depend on how the inevitable churn on LHR slots means VS can get hold of some more. They may also be using the albeit minor threat of Gatwick to apply pressure on HAL not to crank fees up again.
