Air Sylhet AG was its wholly owned, short-lived Austrian airline subsidiary based at Vienna International Airport.

[1] Air Sylhet plc was established in 2007 and a registered UK public limited company which had received over £1m in investment, primarily from the UK Bangladeshi Sylheti community.

Formal notice of its AOC and OL has been published in the Official Journal of the European Union (2008/C 178/15).

[2] Air Sylhet started scheduled flights to Amritsar from Birmingham with a technical stopover at Vienna from 4 April 2009.

However, the sole scheduled route was suspended after just one month when the fledgling business collapsed[3] and subsequently ceased operations.
