While airports around the world, including Heathrow in London, JFK in New York, Los Angeles, Tokyo, Seoul, Hong Kong, Bangkok, Singapore, Frankfurt, are upgrading to welcome the A380, Indian airports will have to gear up too.
Singapore Airlines is expected to fly A380 to either Mumbai or Delhi late next year, making it mandatory for AAI to upgrade these airports.
I hope they upgrade their visa clerks as well. I remember getting out of a plane in Chennai several years ago, collecting my bags, clear customs - everything went nicely until We got stuck for ages in a queue for immigration and visa checking desk. The clerks there seemed to be deliberately working at a snail's pace in order to hold up passengers. In the west you might have thought they were on a go slow work to rule, but no, I found out that this is what clerks and bureaucrats in India do - deliberately make people wait. It seems to give them some perverse sense of power and control - you may be a rich tourist or businessman and they may only be clerks, but they are the bigshots as far as the queue is concerned, and they will make you wait and sweat, just because they can.
I can just imagine the fun when an A380 lands and 840 passengers hit the queue all at the same time.
