A fifth aircraft is being leased to Flybe to operate for SAS under a white label deal.
Aircraft leasing company Avation is to supply the ATR72 turboprop to the UK regional carrier.
All five aircraft will be operated by Flybe from Stockholm on behalf of SAS for at least six years.
Avation executive chairman, Jeff Chatfield, said: “We are pleased to announce this contract for the lease of a fifth aircraft to Flybe, which further strengthens our partnership.
“We look forward to initiating the delivery stream to Flybe, which is scheduled to commence in September 2015.
“The company is also evaluating the potential acquisition of a number of existing aircraft, which are currently on lease to a variety of other airlines.”
Flybe chief executive, Saad Hammad, said: “Flybe has established a strong relationship with Avation. This helped to secure the new contract for a fifth ATR 72-600 aircraft for expanding our white label relationship with SAS.
“We are focused on delivering a first class implementation at SAS when we launch operations in Stockholm for them later this year.”
