The new European SuperJumbo will apparently carry 550 or 800 passengers (depending on who you listen to), Boeing's offering will carry considerably less but it will be an efficient and flexible plane capable of very long hauls. The Airbus will need special king-sized runways, the Boeing won't. Then there are the questions of check-in and baggage collection, both of which will be loads of fun with 800 passengers, particularly after a 10 hour flight. And there's the question of security. All in all, which would you bet on?
