[citation needed] Best Air started with a Boeing 737 to operate from Shahjalal International Airport in Dhaka to one regional domestic destination, Chittagong.

Best Air acquired an McDonnell Douglas MD-83 on lease and operated to new destinations such as Dubai, Kuala Lumpur, Singapore and Bangkok.

Best Air had announced that they have received a large investment from Destiny Group LTD of Bangladesh and will restart operations on 26 March 2011, but did not.

Plans called for the acquisition of three A320 aircraft later in the year, followed by the Airbus A330 or Boeing 777 for long haul routes in the near future,[1][2][3] all of which never materialized.
