Early years Air Botnia was established in 1987 and started operations in June 1988, flying
Embraer EMB-110 Bandeirantes on night cargo flights and on passenger services from
Helsinki to
Kauhajoki and
Seinäjoki. It started to supplement its unpressurised Bandeirantes with leased
British Aerospace Jetstream 31s in 1993, but cash flow problems in the summer of 1995 caused British Aerospace to repossess the Jetstreams and brought Air Botnia to the eve of bankruptcy, but it continued operations in a reduced scale. The airline was purchased by SAS Group in January 1998, who replaced its Jetstreams with
Saab 340s later that year. Air Botnia received its first jets,
Fokker F28 Fellowships, in 1999. Because their high noise levels restricted operations, in 2001 the elderly F28s were replaced by
Avro RJ85s. At the same time the Saab 340s were replaced by larger
Saab 2000s.
Development since 2004 Air Botnia was renamed
Blue 1 O/Y in January 2004, and joined
Star Alliance as its first regional member on 3 November of that same year. The air carrier became a full member of
Star Alliance on 1 January 2009 but left it in November 2012 and became an affiliate of
Scandinavian Airlines. In 2005 Blue1 became the second-largest Finnish airline with more than 100 daily flights and the biggest operator between Finland and the Nordic nations Sweden, Denmark and Norway. In 2006 Blue1 started 10 new non-stop routes to Europe increasing its total capacity by more than 50%. In 2008 Blue1 moved its London operations from Stansted to
Heathrow Airport, and expanded its domestic business routes. In 2009 new routes to
Lapland, including Paris-Kittilä were opened for the winter season and routes to Biarritz, Dubrovnik and Split for summer travel. Blue1 was the first network airline in Northern Europe to be granted ISO 14001 environmental certificate. On 1 November 2012, Blue1 became a service producer for SAS. This means that marketing and sales were then handled by SAS and its flights carried the SAS flight prefix "SK". In March 2015, it was announced that Blue1 was to sell their entire fleet of
Boeing 717-200s to
Volotea and
Delta Air Lines and was to replace them with
Boeing 737-600s from its parent,
Scandinavian Airlines, however Scandinavian Airlines later cancelled the plan and evaluated the transfer some
Bombardier CRJ900 from
Cimber. In October 2015,
Scandinavian Airlines (SAS) announced the sale of Blue1 to
CityJet from Ireland, which was to operate the company on behalf of SAS as part of a larger relationship. Flight operations were halted on 31 October. By December, Blue1 had no more aircraft and its own website was redirected to
SAS's website. In 2016, Blue1 was dissolved and assets merged into its new parent CityJet. ==Onboard services==
