Southwest Airlines recently completed a fleet-wide project to add extra legroom seating. This project, completed in January 2026, involved repitching the all-economy cabins that Southwest operates, with the 737-700s losing a few seats in the process, and on its own, it gives customers more seating choices. However, it was controversial as the extra legroom seats were added in conjunction with Southwest’s rollout of assigned seating, which introduced assignment fees as well as an added surcharge for the new extra legroom seats.
