Southwest Boeing 737-200 - 2005
Southwest, along with America West, retired their 737-200s in January 2005. Delta is now the last mainline carriers in the U.S. to operate the classics, and those will be gone by the end of 2005. Southwest operated the largest 737-200 fleet in the world. Southwest's last 737s were retired to Goodyear, Arizona and Mojave, CA.
