WestJet (WS, Calgary) has sold seven of its retired B737-600s to Aventure Aviation for immediate part-out at Marana.

C-GPWS (msn 34284), C-GWSB (msn 34285), C-GWSI (msn 34286), C-GWSK (msn 34287), C-GBWS (msn 34288), C-GWCQ (msn 35111), and C-GWCT (msn 35112) were all deregistered from Canada on February 15, 2023. Having been scrapped, they were not inducted onto any other register.

The aircraft were retired from active service between March 2020 and February 2021 and ferried to Marana for storage in 2021. They were delivered to WestJet direct from Boeing in 2005 and 2006. The Canadian airline was their only operator.

The ch-aviation fleets ownership module shows that WestJet continues to own five more B737-600s. Three of these are in storage at Marana, while the other two have been leased out to KF Cargo for its passenger charter brand Aeroflyer. The niche variant of the B737NG remains in service with just two more operators in the world; AECOM Federal Services has six units in its fleet and Air Algérie five.
