Alliance & partners
Southwest Airlines is not a member of any alliance. Miles earned fly only within Southwest Airlines's own loyalty program. There are no codeshare or interline agreements with other carriers.
Worth knowing: Southwest uses a point-to-point routing model rather than hub-and-spoke — every route is direct, meaning no connecting hubs, which also means no codeshares or interline agreements with any other carrier.
