One word: Jealousy. He can laugh all he likes about startup issues (of which there is no excuse for), but T5 is larger than any of New York's airports and has its own dedicated rail links to Central London - something that is almost magical when talking about New York. In a months time the issues will be sorted and people will wonder what all the fuss was about, and he'll be the one left with the disjointed terminals and unable to get a one-seat train ride to Manhattan. And to re-cap over other major terminal/airport openings: - With Hong Kong's new airport the old airport had to remain open for a further 6months to handle the problems there. People were even told to avoid Hong Kong because the issues got so bad at one point - Paris' latest terminal collapsed and killed several people - At Changi's new Terminal 3 - an A380 rolled off the runway because of the new apron layout - Madrid's Barajas airport also had similar baggage problems as Heathrow.
