Virgin defers A380 by four years

Virgin is now arguing that it wants the aircraft to prove itself in commercial service for several years before it puts its own A380s into operation.

The airline is now extending its leases on a number of Boeing 747-400 jumbo jets to cover the delay.

BBC business correspondent Hugh Pym said the decision followed what one source described as "tough negotiations on price and other issues".

Well... In that case, Airbus can free up those 6 delivery slots to other airlines so that other airlines will get their earlier or allow SQ 6 follow up orders to fill this gap...
