Cant argue with that, but Klaus Brauer from Boeing stated in Flightglobal last year that the concept had been shelved.
Consideration was also given to using more of the upper spaces aft of the forward upper deck, but the location of several systems made this too costly, says Mooney. Launch customer Lufthansa, plus other potential operators, have shown strong interest in locating the galley and galley cart stowage in the aft upper space. The other upper space study for "Sky Lofts" has been shelved. "The airlines didn't know how to make revenue out of it," says Brauer, who adds that most studies relied on premium pricing for business class, which threatened to "cannibalise first class".
