Frontier Airlines   Boeing 737-247     N7363F      (c/n   20133)

                              

                                  Frontier first put their 737s into service in the sping of 1969, following which the uneconomic 727s
                                  were gradually sold off..   After an initial order for a dozen of the short/medium haul airliners, the
                                  airline went on to operate some 60 of them at one time or another.  More new ones were purchased,
                                  but they also operated a fair number of "previously owned" machines such as this ex Western Air Lines
                                  example above, seen here in this shot by Frank C. Duarte Jr. taken at Denver's Stapleton International
                                  Airport in September of 1982.  Although by that time the airline had arrived at the rather striking new
                                  livery seen in this image, the first 737s were, in fact, delivered in the old scheme as evidenced by the
                                 shot of N7377F seen below seen below.  This photograph is from the Clinton Lincoln collection and
                                 was taken at Lambert Field, St. Louis in June of 1973 (no jetways in those days!).
