Cheap Flights to Las Vegas: Days, Months, and Airlines That Price Lowest
How Las Vegas fares move with conventions and weekends, the months that price lowest, and the carriers that compete on the busiest routes.

Why Las Vegas fares swing
Harry Reid International (LAS) is one of the most competitive airports in the country, with Southwest, Spirit, Frontier, Allegiant, Delta, American, United, and Alaska all flying large schedules. Fares are low on ordinary weekdays and jump for big conventions, fight weekends, and holiday weekends, when the whole city sells out.
Cheapest days and months
Tuesday and Wednesday departures with a Thursday or Sunday-night return usually price lowest; Friday-out, Sunday-back is the most expensive pattern. By month, mid-January to early February, late summer, and early December price lowest, while March, October, and New Year's are the peaks. Check the convention calendar before choosing dates: CES in January and the big trade shows in March and November move fares by $100 or more.
From the West
Los Angeles, the Bay Area, Phoenix, Salt Lake City, Denver, and Seattle all have many daily nonstops and one-way fares that regularly fall under $60. The route pages show the recorded lows and the days that carry them.
From the East and Midwest
Chicago, Dallas, Houston, Atlanta, New York, and Boston have nonstops on several carriers; fares under $150 one-way are common outside peak weekends. Red-eyes back east are the cheapest returns.
The headline fare is not the Vegas total
Las Vegas is the sharpest example of the low-cost-carrier trap, because Spirit, Frontier, and Allegiant fly it hard and price to the eye-catching base fare. That fare often carries no checked bag and sometimes no free carry-on, so a $39 one-way can land closer to a mainline fare once you add a bag each way — and on a short trip you may not need to check anything, which is when the low-cost fare genuinely wins. Compare the all-in price with the bags you will actually carry against the majors' fares that include a carry-on, both directions, before you book the cheapest-looking seat.
Let a red-eye home buy back a night
The cheapest return east is usually the late-night departure, and on a Vegas trip it does double duty: a red-eye lets you keep the last evening and skip paying for a final hotel night, since you fly while you would have been asleep. It only pays off if you can function the next day and have somewhere to land — a shower and a bed on arrival, not a full workday straight off the plane. Weigh the fare saving and the hotel night against the lost sleep; on a short weekend it often tips toward the overnight return.
