Southwest, Frontier, and United all offer daily service on this route, with median fares ranging from $80 on Frontier to $164 on United.", "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates 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; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": ["flight_schedule"]}, "q1": {"question": "Are there any direct flights from Denver to Las Vegas?", "answer": "Yes, there are direct flights from Denver to Las Vegas.

Public buses operated by RTC Southern Nevada provide a cheaper alternative, and the Vegas Loop offers a quick tunnel-based ride to the convention center. Rental cars are available at the consolidated Rent-A-Car Center via free shuttle, and limousines or shared shuttles are also on offer. Taxis and rideshares are the most commonly used due to their convenience and short 10–15 minute trip to the Strip.", "toolsUsed": [], "references": [{"url": "http://www.harryreidairport.com/all-options-to-and-from", "title": "All options to & from Harry Reid | Harry Reid International Airport", "time_published": "2026-01-01T00:00:00Z"}, {"url": "http://www.harryreidairport.com/cookies", "title": "Flights | Harry Reid International Airport", "time_published": "2026-01-01T00:00:00Z"}, {"url": "https://en.wikipedia.org/wiki/Transportation_in_Las_Vegas", "title": "Transportation in Las Vegas", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-07-03T22:51:37Z"}, {"url": "https://en.wikipedia.org/wiki/Harry%20Reid%20International%20Airport", "title": "Harry Reid International Airport", "time_published": "2026-04-30T22:39:45Z"}, {"url": "https://www.fly.faa.gov/fly/flyfaa/flyfaaindex?ARPT=LAS&p=1", "title": "Harry Reid International Airport"}]}, "q4": {"question": "When is the cheapest time to fly from Denver to Las Vegas?", "answer": "From Denver to Las Vegas, the cheapest months to fly are August, April, and October, with average fares as low as $195 in August. The most expensive times are December, June, and November, with December averaging $300.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Denver to Las Vegas?", "answer": "For flights from Denver to Las Vegas, the best fares are typically found when booking 3 to 6 weeks ahead, with an average price around $100 in that window. Around holidays and peak summer times, prices can rise and the ideal booking window may shift a few weeks earlier, so it's wise to monitor fares and book a bit further out for those periods.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Denver to Las Vegas?", "answer": "Yes, overnight red-eye flights are available from Denver to Las Vegas.

On this short route these late departures arrive the same night, typically before midnight.", "methodology": "Red-eye flights are identified from scheduled local departure and arrival 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 — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.", "toolsUsed": ["redeye_flights"]}, "q7": {"question": "Which airlines usually operate this route from Denver to Las Vegas?", "answer": "Southwest, United, and Frontier all fly nonstop from Denver to Las Vegas.

Frontier shows 73% on-time with a -5 minute median delay and 0% cancellations, while Southwest operates with 69% on-time performance, a 0-minute median delay, and no cancellations.", "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Public bus routes, such as the RTD SkyRide, offer a cheaper alternative but take longer.
