A friend at SAIL showed me an email sent to their crews. The "Future enhanced operating model" for SAS shows a new operation with a "single type fleet of mid-sized aircraft" which will focus on "Right sizing and fuel efficiency of thinner flows from Scandinavian bases" (direct quotes from the email). SK will continue to be the "backbone" of the operation, with a combination of SH and LH routes. SAIL will be the A320NEO, focusing on "highly competitive routes and new leisure markets". Wetlease operations are expected to continue with ATR and CRJ aircraft. The letter was dated 20 January 2020.
