There are three international airports in Bangladesh:
Dhaka Hazrat Shahjalal International Airport (DAC; www.shahjalalairport.com)
Chittagong Shah Amanat International Airport (CGP)
Sylhet Osmani International Airport (ZYL)
In practice, the vast majority of foreign visitors arrive at Dhaka’s Hazrat Shahjalal International Airport. It’s pretty basic for a capital-city airport but it has money-changing facilities, including ATMs that accept foreign cards, some duty-free shops and a couple of restaurants.
There’s an official taxi rank, although it’s cheaper to try your luck with taxis and CNGs (auto-rickshaws) outside. The 30-minute haul to Banani, the first prominent residential neighbourhood on your way into the city, will cost you Tk 750 by taxi or Tk 300 by CNG. If you ask your hotel for an airport pick-up, expect to pay around Tk 1000.
The unofficial airport website has a useful flight-status feed.
Biman (www.bimanairlines.com) is the national carrier of Bangladesh. It's a scruffy and curiously disorganised operation, but the fleet is fairly well maintained and the airline has a good safety record.
