China Western Airlines Boeing 737-800 (Classic Livery)
When Boeing started working on a new generation of 737s in 1993, China Western Airlines showed interest in ordering it. Despite not having the performance that the TU-154 was known for, China Western believed that there were a significant amount routes within Western China where the 737NGs could fly. They ordered a few 737-700s and 737-800s and started receiving them in 1999. Despite the 737-800 being shown above, China Western actually preferred the 737-700 because it worked better with the low demand and short runways in Western China. By the time successors for these planes started showing up around 2017, China Western had a huge fleet of both 737-700s and 737-800s, but the successors is a whole other (and very spicy) story.
