Southwest Airlines has canceled three international routes this year, as the airline readjusts its international focus to more lucrative routes. The airline terminated two nonstop services to Cancun International Airport (CUN), while a nonstop service to Los Cabos was also withdrawn. Southwest is the world's largest low-cost carrier with a fleet of more than 800 Boeing 737 jets; however, many critics would now argue the airline is a hybrid carrier, as the airline moves away from the low-cost model and positions itself with a mix of included perks. Southwest Airlines Exits Chicago O'Hare, Terminating Its Route To Cancun Credit: Joseph Creamer | Shutterstock All three of Southwest's international route cuts took place in April, with the service from Chicago O'Hare International Airport (ORD) to the sun-soaked Mexican tourist hotspot of Cancun (CUN). Southwest withdrew from O'Hare completely in the first half of the year, with the Cancun service ending in the Spring. Southwest decided to move away from O'Hare as part of a strategic focus and further development of its extensive operations at the second Chicago airport, Midway International Airport (MDW). Southwest continues to operate nonstop flights to Midway and competes head-to-head on the airport pair with Frontier.

The route to Cancun was cut as part of the airline's broader network strategy reset, which saw the termination of underperforming routes and low-demand international services. Colorado to Cancun services had experienced low load factors and, as suggested by MigFlug, had one of the lowest passenger load factors across the airline's operations. This resulted in the airline removing underperforming routes and deploying its aircraft on more profitable and high-demand services.

Cancun's exit leaves the airport with no international services from the airport, with Denver, Dallas/Fort Worth International Airport (DFW) and Phoenix Sky Harbor International Airport (PHX), the most popular domestic routes.

The route was another culprit under the airline's broader strategy to eliminate underperforming routes.
