Bombardier Commercial Aircraft announced that CityJet has signed a conditional purchase agreement for six CRJ900 aircraft and has also taken options on an additional four aircraft. This purchase agreement is expected to go firm on January 31, 2017. Upon delivery, the aircraft will operate wet lease services on behalf of Scandinavian Airlines (SAS). Based on the list price of the CRJ900 aircraft, the conditional order is valued at approximately USD 280 million and could increase to USD 467 million, should CityJet exercise all its options. CityJet currently owns a fleet of eight CRJ900 aircraft which are on wet lease service with SAS. The airline will also take delivery of four new CRJ900 aircraft in early 2017 as per Bombardier's order announcement on April 25, 2016, bringing CityJet's owned fleet of CRJ900 aircraft to 12. As part of its acquisition of Cimber A/S, a regional airline in Denmark and a former wholly owned subsidiary of SAS, CityJet will operate Cimber's fleet of 11 CRJ900 aircraft also on wet lease service with SAS. These aircraft will be replaced by up to 10 additional CRJ900 aircraft.
