The 380 is going to cripple Airbus.
1. You need strengthened and widened runways and taxiways to handle a plane far wider than the 747 and also weighing around 1 million pounds!
2. You need a terminal gate with increased handling capacity for the plane.
3. You might even need to increase wake turbulence separation for the the A380.
Small wonder why airlines are finding the 777-200LR, 777-300LR, 787-8 and 787-9 vastly more attractive, since they don't need expensive revamping of most current international airports.
The 380 has its niche.
The A318/319/320/321 has been killing Boeing.
2005 sales (Air Transport World, Feb 2006, page 9)
and 235 787's
and 20 A380's
Competition is good!
Airbus produced 378 aircraft last year, Boeing produced 290.
