Denver International Airport (DEN)
Southwest runs around 10 to 12 daily nonstop flights between Denver and Las Vegas, making it one of the most frequently served routes in the airline's network. Flight time is about 2 hours 20 minutes. DEN is a major connection hub for Southwest, so you can link up from smaller cities across the Midwest and Mountain West.
Dallas Love Field (DAL)
Nonstop flights from Dallas Love Field to Las Vegas run about 3 hours. Southwest operates multiple daily departures from its headquarters airport, and you can usually find fares starting around $79 one-way during off-peak periods.
Chicago Midway International Airport (MDW)
Midway to Las Vegas is roughly 3 hours 40 minutes nonstop. Southwest offers several daily flights, and MDW's smaller size means shorter security lines compared to O'Hare. Parking at Midway is also cheaper.
Los Angeles International Airport (LAX)
One of the shortest Southwest routes to Vegas, clocking in at about 1 hour 10 minutes. Multiple daily nonstop flights keep fares competitive, with one-way tickets sometimes dropping to $49 during fare sales.
Phoenix Sky Harbor International Airport (PHX)
Another quick hop, Phoenix to Las Vegas takes about 1 hour 10 minutes nonstop. Southwest operates several flights daily, and the short distance means this route rarely exceeds $100 one-way even during busy periods.
Baltimore/Washington International Airport (BWI)
East Coast travelers can reach Las Vegas nonstop from BWI in around 4 hours 45 minutes. Southwest typically offers 3 to 4 daily nonstop flights. BWI's lower airport fees tend to keep ticket prices below what you'd find at DCA or IAD.
Cheapest Months to Travel
January, February, September tend to have the lowest fares for Southwest flights to Las Vegas. Demand drops off and you'll find better seat availability during these months.
Peak Travel Seasons to Avoid
March (March Madness/spring break), major holiday weekends like New Year's Eve and Thanksgiving, and big convention weeks (CES in January can spike prices too)
Best Time to Book
Booking 3 to 6 weeks ahead usually gets the best fares. For holiday weekends or convention dates, 2 to 3 months out is safer.
Midweek Advantage
Tuesday and Wednesday departures tend to run $20 to $40 cheaper than Friday or Sunday flights on most routes.
