The Airbus A380, today’s largest commercial aircraft, is currently doing a tour of the United States. It was visited by journalists. The article indicates that no US airline ordered the aircraft, and delays caused the few orders of the cargo version to be cancelled.
On the surface, it sounds like a good plane. Any way to travel that burns less fuel is good to take (though how much of this is propaganda is honestly hard to tell…). I hope I can travel in one of these planes someday.
