One-Way Flights to Las Vegas

Las Vegas is one of the cheapest domestic destinations to fly to one-way, thanks to intense airline competition. Budget carriers like Frontier and Spirit frequently run sub-$50 one-way fares from major hubs like Chicago, Los Angeles, and Denver. The best time to book is 3-6 weeks in advance for domestic one-way flights. Tuesday and Wednesday departures are consistently the cheapest. If you're flexible on dates, use Google Flights' price calendar to spot the lowest fares. Southwest Airlines is worth checking separately — they don't appear on Google Flights but often have competitive one-way prices with free checked bags. For the absolute cheapest fares, fly midweek and avoid holiday weekends, CES week (early January), and major fight nights.
