Air Inuit (3H, Kuujjuaq) took delivery of the first two B737-800s due to be converted into combi freighters under KF Aerospace's new Supplemental Type Certificate (STC).

C-FTUY (msn 40853) and C-FTUW (msn 40852) are 2010 model sisterships formerly operated by Comair (South Africa) (CAW, Johannesburg O.R. Tambo) and sold as a part of the defunct carrier's ongoing liquidation. Both underwent pre-delivery maintenance at Johannesburg O.R. Tambo and were ferried out of South Africa via São Tome and Santa Maria, PT to Montréal Trudeau over the course of August 21-23, 2023.

The carrier plans to add three B737-800 Combis to replace its four gravel-kit-equipped B737-200Cs. The aircraft will be outfitted with main deck cargo doors but will also carry passengers. They will not, however, be equipped to operate from gravel runways, which will necessitate infrastructural upgrades in the Nunavut territory.

KF Aerospace's B737-800 conversion will be the world's first combi STC for the type. While the B737-200, the B737-300, and the B737-400 were available in a combi layout, none of the B737NG variants ever were.
