Improvement within a span of a couple of years. Hopefully more to come. It's no Singapore or Dubai, but it's no Mumbai or Calcutta either. Small, efficient and tidy for the most part. Transit passengers may be bored during long breaks. Not a lot to do. Next improvement must involve changing of several security personnel who ruin the day by their misguided pride in their work. First time foreigners with no one to meet may still be perplexed at the chaos once outside the neat terminal.
