On 1 April 2015, Flydubai resumed foreign airline service to Sylhet with its flight from Dubai–International. Flydubai's introduction of nonstop flights from Dubai became the first international flights to Sylhet since the airport's "international" designation 18 years prior. The service was operated through a codeshare agreement with Bangladeshi airline Regent Airways. However, because Biman Bangladesh Airlines had refused to provide ground handling services, the route was cancelled the next day. Stranded passengers held a demonstration in response on 6 April 2015. On November 2016, Flydubai decided to start its flight again from Sylhet to the Middle East. This flight was ended on 7 September 2018
