List of Southwest Airlines destinations

Southwest B737 on final approach to San Jose International Airport.

Southwest does not use the "hub and spoke" system of other major airlines, preferring instead the "point-to-point" system with focus cities.[3] It has large operations in certain airports. An average of 80 percent of Southwest passengers are local passengers—only 20 percent are connecting passengers, a lower percentage than on most major airlines, where many passengers connect in hub cities. However, at Southwest's focus cities, the percentage of connecting passengers can reach 30 percent.[4] As part of its effort to control costs, Southwest historically used secondary airports in cities where the primary airports have high costs, such as Chicago, Dallas/Fort Worth, Houston and Miami. In recent years however, the airline has been expanding into primary airports as well.[5] In most cities where Southwest uses both a primary and secondary airport, the secondary airport is used more than the primary for flights (such as Oakland instead of San Francisco), with some exceptions such as the Los Angeles metro area, where Los Angeles International is a Southwest base and secondary airports (such as Burbank, Long Beach, Santa Ana and Ontario) have limited Southwest operations despite having a higher market share at the smaller airports.

Unlike most other U.S. airlines, it does not fly outside the continent of North America (except to Hawaii), and it does not fly to Canada due to its payment system not being set up for Canadian dollars (however, Southwest does market Bellingham to cater to Canadian passengers in the Vancouver and Southern BC area as a low cost alternative to Vancouver International Airport).[6]
