Las Vegas flight ticket prices depend on your departure airport, travel dates, airline, and how far in advance you book. Travelers can sometimes find domestic round-trip tickets under $150 during quieter periods, while popular weekends and major events may cost considerably more. January, February, and late August are worth checking for cheaper flights, although prices are not consistently low throughout those months.
Flying during the middle of the week and comparing several departure dates can help reduce costs. Here’s what to know about Las Vegas airfare, including seasonal prices, booking windows, airline fees, and ways to find better deals.
How Much Are Flights to Las Vegas?
Domestic flight prices vary considerably depending on distance, demand, and departure city.
The following table provides illustrative round-trip economy price ranges rather than current airfare quotes.
| Flight Type | Illustrative Round-Trip Price |
|---|---|
| Short Domestic Routes | 80–200 |
| Medium-Distance Routes | 150–350 |
| Long-Distance Domestic Routes | 200–500+ |
| Holiday or Major Event Flights | Can Exceed Normal Fares |
These are budgeting examples, not verified live fares or national averages. Actual prices may fall outside these ranges.
Travelers flying from nearby cities such as Los Angeles or Phoenix may find lower fares than those departing from the East Coast.
Direct flights, checked luggage, and premium seating can increase the final cost.
Cheapest Months to Fly to Las Vegas
January, February, and late August are useful periods to compare when looking for lower airfare.
January and February
The cooler winter weather reduces demand for outdoor pool parties and summer-style activities.
However, January includes major conventions such as CES, which can increase airfare and hotel prices considerably.
February also has busy weekends around major sporting events and Valentine’s Day.
Late August
Late August may offer cheaper flights as summer vacations end and temperatures remain high.
Las Vegas daytime temperatures frequently exceed 100°F during this period.
Travelers comfortable with extreme heat may find worthwhile airfare and hotel combinations.
Most Expensive Months
March, April, October, and November can have stronger travel demand due to pleasant weather, conventions, and major events.
However, no single month is guaranteed to be the most expensive.
Cheapest Days to Fly to Las Vegas
Flying during the middle of the week can be less expensive than traveling on busy weekends.
Google Flights’ 2026 research found that departing Monday and returning Tuesday or Wednesday offered savings compared with weekend itineraries.
| Travel Days | Typical Pricing Pattern |
|---|---|
| Monday–Wednesday | Often Lower |
| Thursday | Depends on Demand |
| Friday | Popular Arrival Day |
| Saturday | Varies by Route |
| Sunday | Popular Departure Day |
Las Vegas attracts weekend visitors, making Friday arrivals and Sunday departures worth comparing against alternative dates.
Important: There is no guaranteed cheapest weekday for every flight.
Best Time to Book Las Vegas Flights
Google Flights’ 2026 analysis found that domestic airfare reached its lowest average price approximately 39 days before departure, with a historical low-price range of 22–57 days.
For international flights, the average low point was approximately 89 days before departure.
These are historical averages, not fixed booking rules.
| Flight Type | Booking Approach |
|---|---|
| Domestic | Compare prices 1–2 months ahead |
| International | Begin searching several months ahead |
| Major Holidays | Book earlier when dates are fixed |
| Major Conventions | Monitor fares well in advance |
| Last-Minute Travel | Expect fewer low-priced options |
For popular events such as Formula 1 or CES, booking earlier may be worthwhile even if historical averages suggest waiting.
Budget Airlines vs. Major Airlines

Budget carriers may advertise lower base fares, but optional services can add significant costs.
