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 Milwaukee 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 Milwaukee to Las Vegas.

What is the typical flight duration from Milwaukee to Las Vegas?

The flight from Milwaukee to Las Vegas is about 1,520 miles. The typical nonstop flight time is 3 hours and 50 minutes. The return flight to Milwaukee is shorter, at 3 hours and 30 minutes.
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 Milwaukee to Las Vegas?

Yes, Southwest Airlines flies non-stop from Milwaukee to Las Vegas, with 19 flights a week and daily service. Multiple departures run each day, spread across morning, midday, and evening times.
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?

From Harry Reid International, taxis and rideshares like Uber and Lyft are the fastest and most-used ways to reach the Strip, taking about 15 minutes and costing $15–40. Public RTC buses (Routes 108, 109, and the Centennial Express) are the budget option at $1–3, though they take 30–60 minutes. Shared shuttles run $12–25 per person, private SUVs cost $45–90, and rental cars are staged three miles away at the consolidated Rent-A-Car Center with free shuttle access. There is no passenger rail or monorail link from the airport itself.

When is the cheapest time to fly from Milwaukee to Las Vegas?

Fares from Milwaukee to Las Vegas are lowest in early January, around $309. January is the cheapest month overall, averaging $313, followed by February ($342) and August ($349). December is the most expensive month at about $394, and fares peak in late December at about $415. The yearly average is $359. 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 Milwaukee to Las Vegas?

Book about 7 weeks before departure for the best fares from Milwaukee to Las Vegas, around $343. Booking in the final days before the flight costs about $540, $197 more. Booking six months ahead runs about $568. 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 Milwaukee to Las Vegas?

There are no nonstop red-eyes from Milwaukee to Las Vegas, but connecting itineraries with an overnight long leg do operate. Southwest offers an overnight leg from Chicago Midway to Las Vegas departing 22:55 and arriving 00:55 in the early hours, and American offers an overnight leg from Charlotte to Las Vegas departing 22:35 and arriving 00:31 just after midnight.
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 Milwaukee to Las Vegas?

Southwest Airlines is the only carrier currently scheduled non-stop from Milwaukee to Las Vegas, operating 19 flights per week with daily service. Flights depart throughout the day from early morning through late evening, with several departure options each day. No per-carrier fare information is provided for this route.
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 Milwaukee to Las Vegas?

Southwest Airlines operates this route, landing within 15 minutes of schedule 83.5% of the time, with a cancellation rate of just 0.1%. That makes it the most reliable carrier on Milwaukee to Las Vegas.
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).

Southwest Airlines currently operates the nonstop flights from Milwaukee to Las Vegas, flying Boeing 737s on the route. Their schedule includes Boeing 737-700 and Boeing 737 MAX 8 aircraft, both from the Boeing 737 family.
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.
