Another early 737, this one delivered on lease from owner GATX to Aloha Airlines February 11, 1969. Frontier leased it from January 1970 and it combined into Continental Airlines' fleet when the two merged in November 1986. Leased to Southwest Airlines in August 1987, the 737 was returned to Continental January 1, 1989 and re-registered N10242 the following July. Eventually utilized for parts, the registration was cancelled in June 1998.

Delivered to Capital Airlines in 1957 who merged with United in 1961.

Acquired in the merger with Air Oregon in 1982 (N5478M) and upgraded it to a Metro III for fleet standardization. Returned to the lessor December 1996 as Horizon replaced the Metro fleet with Dornier 328s (and shortly after, the Dorniers with Dash 8s). It became N227FA and was parted out after 2003.
