Earlier this summer Southwest Airlines announced that from 11 November it would begin serving Cancún from Nashville, with the announcement being celebrated by both airport and airline staff members at the Tennessee airport. The carrier will offer a weekly (Saturdays) service on the 1,675-kilometre sector, flown by 737-700s.
- Southwest Airlines began two new routes to Cancún (CUN) on 11 November, with the carrier now linking the Mexican resort with Nashville (BNA) and St. Louis (STL) on weekly (Saturdays) flights. The 1,675-kilometre link from the Tennessee airport will face direct competition from American Airlines (weekly), while the 1,994-kilometre sector from Missouri will go head-to-head with Frontier Airlines (daily). When referring to OAG schedules, both routes will be operated by Southwest on its fleet of 737-700s. As a result of launching flights from Nashville and St. Louis, Southwest now connects Cancún to 11 destinations at the start of W17/18, while for both US airports, Cancún becomes the carrier’s only international gateway from either hub.
