NextJet was a partner of the Swedish cross country skiing team and introduced this flag-themed logojet in time for Winter 2009/2010. Note on the picture, the small team decals had already been removed.
Promoting one of the airline's destinations: Kramfors and Sollefteå in north-central Sweden were both served by the Höga Kusten Airport (Kramfors-Sollefteå). Kramfors decals on the port side & Sollefteå titles on the starboard side.
These titles celebrated Kevin Borg's win of the Swedish singing competition Idol in December 2008. Borg moved to Arvidsjaur (a town served by NextJet) when arriving from Malta where he was born, hence the titles.
