Southwest Airlines made this short statement on social media:
Tonight (September 29, 2017), we sent our last The Boeing Company 737-300 aircraft out in style. Flight WN68 flew from HOU-DAL in its farewell appearance in our fleet. We say thank you for 32 years and good night to the Boeing 737-300.
The last 737-300 revenue flight was operated with the pictured Boeing 737-3H4 N632SW (msn 27707).
As a result of the 737-300, today, October 1, 2017, Southwest also introduces the Boeing 737 MAX 8 on revenue flights.
