Virgin Atlantic stations its B747-400s at London Heathrow (LHR), Manchester (MAN) and Gatwick (LGW).

Those aircraft at MAN or LGW have a bigger economy section than those at LHR, as they are mainly used on leisure routes such as the Caribbean. 

The layout of these 747s have a small Upper Class cabin, with Premium Economy taking up the entire upstairs floorspace, as these are used on economy-dominated leisure routes such as Orlando.
