The airline was created in November 2003 as a home carrier for tour operator Jetair, part of the tourism group TUI AG. The original plans were to operate two aircraft, but after charter company Sobelair ceased its operations, Jetairfly started its operations with 5 aircraft. On 23 November 2005, The airline was rebranded Jetairfly as part of the rebranding around Belgium's number 1 tourism brand Jetair. In January 2012, Jetairfly announced that Jet4you, a low-cost Moroccan carrier and also a subsidiary of the TUI AG Group, would be fully integrated in Jetairfly. The merger was complete in April 2012. In March 2012, Jetairfly officially became a full scheduled airline, while previously a part of their flights were conducted as charter flights. As a result, all flights can be booked in both directions even by non-EU citizens. In the beginning of 2013, Jetairfly was the first leisure airline worldwide to introduce the Embraer E-Jet 190 in its fleet. In the autumn of 2013, the new office building and maintenance hangar "Jetairport" was inaugurated at Brussels Airport. In December 2013, Jetairfly was the first and only Belgian airline to introduce the brand newBoeing 787-8 "Dreamliner". On 14 November 2014, Jetairfly sealed a wet-lease deal to provide up to four aircraft with crew to operate on behalf of ECAir, the flag carrier of the Republic of the Congo, from mid-2015 on. In 2015, it was the first and only Belgian airline with an ISO 14001 certification for their focus on sustainability and the smallest ecological footprint. On 13 May 2015, it was announced by the TUI Group that all five of TUI's airline subsidiaries will be named TUI fly, whilst keeping their separate Air Operator's Certificate, taking over three years to complete. On 19 October 2016, Jetairfly received the new brand name TUI fly Belgium with the legal name still being TUI Airlines Belgium NV as the second airline within the TUI group which underwent the name change.
