http://www.msnbc.msn.com/id/6843272/ The A380 double-deck superjumbo, unveiled Tuesday, is the world's largest passenger plane. Announcing Virgins plans for the double-decker which was unveiled Tuesday in Toulouse, France, Branson said a gym and gambling area offering blackjack and roulette would be available to economy and business class passengers. Virgin Atlantic, which already offers seats which convert into double beds on some of its existing aircraft, plans to install 35 private double beds on each A380. Virgin Atlantic, which is 49 percent owned by Singapore Airlines, has ordered six A380s with options for a further six, worth a total of $3 billion. The first aircraft is scheduled for delivery in May 2008. Virgin Atlantic was originally scheduled to take delivery of the A380 in 2006 but delayed the plans due to concerns that some major airports, particularly Los Angeles, would not be ready to accommodate the plane in time, as well as delays in sourcing components for some design innovations. Branson said Virgin Atlantic was now confident that airports were prepared and suggested the company would take up its options for a further six planes sooner rather than later. The chances are we are going to want more than six, he said. He also said that A380 parent Airbus had guaranteed Virgin the plane would deliver lower operating costs and had promised to compensate the airline if cost savings dropped below a certain level.
