The significance of Las Vegas' Harry Reid International Airport (LAS) is for multiple reasons. Obviously, they include being a major city and a world-renowned tourist destination and conference location. But it is also influenced by the significance of connecting traffic, with 35% of its passengers transiting on another flight there. These things, and much more, contribute to LAS welcoming 11 new routes: eight domestic and three international. Southwest's Eight New Domestic Routes From Las Vegas Credit: Southwest The carrier's schedule from LAS was explored using Cirium Diio data. This looked at everywhere served in 2025, and then compared the network to what is operating in 2026 or which is scheduled to commence in the remainder of the year through June 2027. Things will inevitably change, so treat it for what it is: a snapshot as of October 26. Launch Month (2026/2027 Only) Southwest From LAS To... Operations Previously Served By Southwest? Head-To-Head Competition (2026/2027)? April 2026 Santa Rosa Daily No: Santa Rosa is a brand-new destination in Southwest's overall network in 2026 Yes: Alaska Airlines May 2026 Anchorage Daily (seasonal) No: Santa Rosa is a brand-new destination in Southwest's overall network in 2026 Yes: Alaska Airlines August 2026 Hilo Three to four weekly No No March 2027 Boston Up to daily No Yes: Delta Air Lines and JetBlue March 2027 Knoxville Two to three weekly No Yes: Allegiant Air March 2027 Miami Five weekly No Yes: American Airlines and Frontier (only scheduled until November 2026) March 2027 Philadelphia Four weekly Yes: until 2019 Yes: American and Frontier June 2027 Harlingen Weekly No No The most notable addition was Anchorage International Airport (ANC), with Alaska welcoming the self-described hybrid carrier for the first time in 2026. It operates from both LAS and Denver. DOT data for May to July 2026 shows that 18,426 passengers were transported to/from LAS, but the load factor was just 67.9%. Even July was only marginally better (71.9%), although fare data is unavailable. This initial performance explains why the route will commence nearly three weeks later in 2027. Then There Are These Three International Routes Credit: Ryken Papy | Shutterstock 2026 was historical for various reasons, including being the first time that Southwest flew internationally from LAS. Interestingly, not even the ever-popular Cancun, served through Cancun International Airport (CUN), was served by another carrier when Southwest launched flights in June. However, it has had various operators over the years. For example, Volaris operated in 2014/2015, Frontier did so in 2018/2019, and JetBlue attempted to make the market work in 2021/2022. Launch Month (2026/2027 Only) Southwest From LAS To... Operations Previously Served By Southwest? Head-To-Head Competition (2026/2027)? June 2026 CUN Up to daily No No June 2026 Los Cabos Up to daily No Yes: Alaska Airlines operated until April 2026. It was unserved thereafter November 2026 Puerto Vallarta Up to five weekly No Yes: Alaska Airlines operated until February 2026. It was unserved thereafter None of the carriers which flew between LAS and CUN lasted for long. Things might be a little easier for Southwest. It'll benefit from its huge brand name in Sin City and its considerable network from LAS. It'll easily be able to supplement the local LAS-CUN traffic with transfer passengers. However, this approach did not work overly well for the first season of LAS-ANC. Will CUN be different?

Of course, things could change. In early 2026, the carrier revealed service from Sin City to San Jose, Costa Rica. It was set to be Southwest's longest international operation and the airline's first overnight international route. However, the link was pulled in July before the first flight took off. Then there LAS to Chicago O'Hare International Airport (ORD). This airport pair was served between May 2021 and June 2026, with the exit entirely because Southwest has pulled out of ORD. Of course, the airline's very long-standing service between LAS and Chicago Midway continues, with up to eight daily departures this year.
