Etops773
Despite what you think of the 747-200 (and we all love nice new jets) Virgin are still paying leases on the 747-200s and will have to for the time being; therefore they either leave them in the desert rotting until the leases expire or operate them in an attempt to re-coop some of the costs.
They (ex-ANZ) are in quite good nick and have the latest interiors and IFE, they don't even use that much gas, so are quite good for using on certains parts of Virgin's route network.
