Cox's Bazar Airport — Cox's Bazar, Bangladesh

Cox's Bazar Airport, using the code CXB, sits beside what is often described as one of the longest unbroken stretches of sand beach anywhere, making tourism the backbone of demand for flights into this southeastern Bangladeshi city. Beyond holidaymakers, the airport has taken on humanitarian significance in recent years as a logistics point supporting relief operations for the large Rohingya refugee settlements nearby, among the biggest such populations anywhere on earth. The facility doubles as a Bangladesh Air Force base, and infrastructure upgrades, including runway work extending toward the Bay of Bengal, have aimed at eventually supporting international flights alongside its busy domestic schedule.
