Methodology: learn how we calculate these charts
The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from St. Louis to Las Vegas cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.
Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.
Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.
The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.
Frequently Asked Questions
Everything you need to know about flying from St. Louis to Las Vegas.
What is the typical flight duration from St. Louis to Las Vegas?
Flights from St. Louis to Las Vegas cover about 1,370 miles and typically take about 3 hours and 30 minutes nonstop. The return leg from Las Vegas to St. Louis usually runs about 3 hours and 15 minutes, so the eastbound flight is slightly shorter by roughly a quarter of an hour.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.
Are there any direct flights from St. Louis to Las Vegas?
Yes, there are direct non‑stop flights from St. Louis to Las Vegas. Southwest Airlines is the main carrier, running up to 37 flights a week with departures spread daily from early morning through late evening, while Frontier Airlines also flies the route once daily at 19:10. Both airlines operate non‑stop every day of the week.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours.
What are the ground transportation options in Las Vegas?
Taxis, Uber/Lyft rideshare, shared shuttles, private SUVs, and RTC public buses all connect Harry Reid International to the Strip and downtown, with taxis and rideshares being the fastest at roughly 10-15 minutes for $15-40. Rideshare is the most-used option thanks to its well-marked pickup areas in both terminals, while the RTC 109 bus is the budget choice at $1-2 but takes 30-60 minutes with stops. Car rentals are available at the off-site Rent-A-Car Center with free shuttles, and there is no rail link from the airport to the Strip. The Las Vegas Monorail serves Strip hotels but does not extend to LAS.

When is the cheapest time to fly from St. Louis to Las Vegas?
Fares from St. Louis to Las Vegas are lowest in early February, around $295. February is the cheapest month overall, averaging $302, followed by January ($305) and August ($319). March is the most expensive month at about $366, and fares peak in late December at about $385. The yearly average is $338. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.
How far in advance should I book tickets from St. Louis to Las Vegas?
Book about 5 weeks before departure for the best fares from St. Louis to Las Vegas, around $239. Booking in the final days before the flight costs about $358, $119 more. Booking six months ahead runs about $392. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.
Are overnight (red‑eye) flights available from St. Louis to Las Vegas?
There are no nonstop red-eye flights from St. Louis to Las Vegas. Connecting itineraries do exist whose overnight leg is a red-eye, such as a Southwest flight departing Baltimore (BWI) at 9:55 PM and arriving in Las Vegas at 12:10 AM — landing just after midnight in the early hours — or a Southwest flight out of Orlando (MCO) at 10:35 PM arriving at 12:40 AM.
Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.
Which airlines usually operate this route from St. Louis to Las Vegas?
Southwest Airlines and Frontier Airlines fly nonstop from St. Louis to Las Vegas. Southwest operates up to 37 weekly flights with departures throughout the day, while Frontier flies once daily in the evening. Both carriers serve the route every day of the week.
Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.
How reliable are on‑time arrivals on this route from St. Louis to Las Vegas?
Frontier Airlines is the most reliable carrier on this route, with 80.5% of arrivals landing within 15 minutes of schedule and a 2.4% cancellation rate. Southwest Airlines follows with an 80.3% on-time arrival rate and a notably lower 0.6% cancellation rate.
Methodology
On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

What aircraft are typically used on flights from St. Louis to Las Vegas?
Southwest Airlines operates most flights from St. Louis to Las Vegas using Boeing 737-700 aircraft, while Frontier Airlines flies the route with Airbus A320 family jets. Southwest also lists Boeing 737 family equipment on this route.
Methodology
Aircraft types come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
