I had the misfortune to fly home from Chennai airport just under two weeks ago. It must be the slowest airport in the world. I've been to India six times now so am well acquainted with the slowness of almost everything in the country. However one expects better of an airport especially one that's fairly new and modern-looking and no other Indian airport I've travelled flown home from has been as bad. The first queue was a long one but no longer than many other airport queues I've been in but unlike in most other airports it hardly moved the queue for immigration at Heathrow when I got home was just as long but constantly moving so didn't take too long. The Chennai queue was unbelievably slow. Then came the queues (plural) for security. I understand that they have good reason to take security seriously and I'm glad they do but they kept recalling bags to have another look at them and then someone would search them by hand. One young woman who was just in front of me had her handbag taken from her and put through three times and searched by hand twice - this really can only mean that the staff didn't do it correctly the first time unless it was the result of a malicious desire to make passengers miss their flights. My bag was put through the scanner twice and searched by hand. I saw this happening to other people too. This was on top of the body searches of course (which I know are necessary but do add more time to the process). This is without question the most inefficient airport I've ever used and I shall do my best never to have to use it again.
