JMC Air was initially announced in 1999, with a five year, £200m rebranding plan to join three of Thomas Cook's holiday brands Sunworld, Sunset, Inspirations and Flying Colours and Caledonian airlines.

[9][10] JMC Air became closely linked to Condor as a result of the acquisition, and was estimated to control 16% of all European charter airline seats.

[14] Prior to launch in 1999, JMC Air sought to acquire Boeing's latest 757-300 aircraft which led to them becoming the first UK operator of the -300 in 2001.

[19] JMC Air also closed three bases in the UK, as a result of lower passenger numbers in the wake of the September 11 attacks.

[22][23][24][25] In early 2002, a JMC Air passenger successfully won damages for suspected deep vein thrombosis as a result of a long-haul flight from Calgary to Manchester.

[33][34][35] In 2001, JMC engaged in an advertising campaign for better air health with popular television fitness expert Mr Motivator.
