We recently flew from Aruba (AUA) to Orlando (MCO) on a Southwest 737-700 that had clearly seen some miles—and years. Looking up the tail number (N480WN), we found out this aircraft first flew in 2005. That makes it 20 years old… and it felt like it. An Aging Cabin That Shows Its Age Southwest still operates a large fleet of 737-700s, but they’re usually assigned to shorter hops within the U.S. This particular plane isn’t often used for longer flights, such as our 3-hour trek from the Caribbean. And while the flight was smooth and the crew was great (as usual), the aircraft itself left a lot to be desired.
