The return leg is around 2 hours and 10 minutes, so the outbound flight is slightly longer. Southwest, United, and Frontier all operate daily nonstop service on this route.", "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"]}, "q3": {"question": "What are the ground transportation options in Denver?", "answer": "Denver International Airport (DEN) is about 25 miles from downtown, and the most-used option is the RTD A-Line train, which runs from the airport transit center to Denver Union Station in about 37 minutes. Ride share services like Uber and Lyft are readily available and offer direct door-to-door convenience, while taxis provide a flat-rate metered alternative. On-site rental car agencies are accessible via a free shuttle, and regional buses, shared vans, and hotel shuttles also serve the airport. The A-Line train is generally the fastest and most popular choice for reaching the city center.", "toolsUsed": ["article_lookup"], "references": [{"url": "https://www.flydenver.com/parking-and-transportation/to-and-from/airport-transit-center/", "title": "Airport Transit Center | Denver International Airport", "time_published": "2026-02-24T17:09:34Z"}, {"url": "https://flydenver.com/connections/", "title": "Connections | Denver International Airport", "favicon": "https://flydenver.com/apple-touch-icon.png", "time_published": "2023-09-14T15:33:21Z"}, {"url": "https://en.wikipedia.org/wiki/Automated_Guideway_Transit_System_(Denver_International_Airport)", "title": "Automated Guideway Transit System (Denver International Airport)", "time_published": "2026-06-01T08:54:40Z"}, {"url": "https://en.wikipedia.org/wiki/Denver%20International%20Airport", "title": "Denver International Airport", "time_published": "2026-04-30T15:08:23Z"}, {"url": "https://www.faa.gov/?action=searchForAirport&airportcode=PSR", "title": "Federal Aviation Administration", "favicon": "https://www.faa.gov/themes/custom/faa/favicon.png", "time_published": "2026-07-17T12:00:00Z"}]}, "q4": {"question": "When is the cheapest time to fly from Austin to Denver?", "answer": "The cheapest months to fly from Austin to Denver are August, September, and October, with average fares around $201–$214. The most expensive months are November and December, where prices climb to $328–$342, while late spring and early summer see moderate fares.", "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 Austin to Denver?", "answer": "For flights from Austin to Denver, the best fares are typically found when booking 5 to 8 weeks ahead, with an average price around $143. The absolute cheapest fares appear about 50 days out, while last-minute bookings can spike to over $300. During summer and holiday periods, demand pushes prices higher, so aiming for the earlier end of that window or even slightly further out is wise.", "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 Austin to Denver?", "answer": "Yes, overnight red-eye flights are available nonstop from Austin to Denver. Southwest operates red-eyes on Monday, Thursday, Friday, and Sunday with departures around 9:50 PM to 10:50 PM, and Frontier flies red-eyes on Monday, Friday, and Sunday departing around 9:23 PM. These flights are short enough that they land 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 Austin to Denver?", "answer": "Southwest, United, and Frontier all fly nonstop from Austin to Denver. Southwest operates the most flights, with about 201 departures per week, while United offers around 122 weekly flights, and Frontier runs approximately 21. The schedule data does not include per-carrier median fares for this domestic route.", "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).

It is located about 25 miles northeast of downtown and serves as a hub for United and Southwest, handling all domestic and international flights to the city."}, "q13": {"question": "How do I get to Bergstrom Intl Airport from the city center?", "answer": "From downtown Austin, the most popular option is a ride-share or taxi, which takes about 15–20 minutes and is generally the fastest door-to-door choice, though more expensive than public transit. Capital Metro’s high-frequency Route 20 bus provides a direct, budget-friendly link from central Austin to the airport, with a travel time of roughly 30–40 minutes. Driving and parking at the airport is convenient, with two on-site garages and an economy lot offering shuttle service to the terminal, while a cell phone waiting lot is available for pick-ups.
