A few tips for Dhaka ZIA.  If departing, there is a nice cafe on the first floor that few people know about.  Alternatively, sit away from the gates near to passport control- there are lots of seats there and its quiet. On arriving, if you need transport, walk away from the terminal and jump into an auto rickshaw/baby taxi or get a taxi from the roundabout just outside the airport. I like this airport- people are friendly, many other passengers are curious about foreigners, and things seem to work well here
