N686SW / N770SA (cn 23175) A pair of Southwest 737's sit in the sun getting serviced for their next trip. The aircraft in the foreground, N686SW, has certainly been around. Delivered in 1986 to Canadian operator CP Air (as C-FCPK), it then went on to fly with VASP (as PP-SNT), GPA (as PT-WBF and EI-CHD), and Morris Air (EI-CHD) before going to WN in 1995.
