SAS Scandinavian Airlines (SK, Copenhagen Kastrup) retired its last B737-600 - and also the last active unit of the type in Europe - on November 30, 2019.

LN-RPG (msn 28310), a 20.7-year-old jet owned by AELF - Aircraft Engine Lease Finance and operated thus far by SAS, undertook its last scheduled revenue flight from Malmö to Stockholm Arlanda as SK108, Flightradar24 ADS-B data shows. It subsequently operated a one-off goodbye flight from Stockholm to Oslo Gardermoen with a low-pass over Copenhagen Kastrup. It has remained in the Norwegian capital since then.

The Scandinavian carrier is currently in the process of renewing its narrowbody fleet and replacing all of its Boeing aircraft with Airbus. The airline's present narrowbody fleet includes four A319-100s, eleven A320-200s, twenty-one A320-200neo, eight A321-200s, twenty-four B737-700s, and twenty-nine B737-800s. It has a further thirty-eight A320neo on firm order from Airbus and also intends to take three A321-200neo(LR) next year, although the latter type will be used for medium- and long-haul flights.

B737-600s are still operated by WestJet (13), Tunisair (seven), AECOM Federal Services (six), and Air Algérie (five).
