Northern Air Cargo's N401YK (c/n 25860, l/n 2545), a 737-436F, is flying to HNL from ANC (via OAK) as NAC401. It's being temporarily assigned to Aloha Air Cargo.
25860 was originally delivered to British Airways in December 1993 as G-BHVB. In April 1994, it was leased to EuroBelgian Airlines [BQ/EBA] as OO-LTS. From February to October 1996, it was sub-leased to Air Provence Charter [LPU] (France) as OO-LTS. It was returned to British Airways in October 1996, but was re-registered as G-GBTB, and flew with the airline until May 2015, when it was retired to VCV a few weeks later. Six months later, it was acquired by Automatic LLC, and stored at TPA. In May 2017, it was converted to a freighter, then leased to Northern Air Cargo a month later.
