Nonstop service takes around 10 hours 10 minutes heading west, while the return leg is about 9 hours 10 minutes — the outbound is roughly an hour longer due to prevailing winds.", "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 Dallas?", "answer": "At Dallas/Fort Worth International Airport, you have access to ride-share services, taxis, rental cars, and public transit directly from the terminals. The DART Orange Line provides rail service from Terminal A to downtown Dallas, while TEXRail from Terminal B connects to Fort Worth, and the TRE Link shuttle connects to the Trinity Railway Express for travel between the two cities. Ride-share and taxi are the fastest door-to-door options, but DART rail is the most-used and cost-effective way to reach downtown Dallas without traffic.", "toolsUsed": [], "references": [ { "url": "http://dfwairport.com/dfwnewsroom/dfw-is-ready-to-welcome-fifa-fans/", "title": "DFW International Airport | Official Website", "time_published": "2026-04-02T00:00:00Z" }, { "url": "https://www.dfwairport.com/explore/transportation/publictransit/?utm_source=google&utm_medium=organic", "title": "DFW International Airport | Public Transit", "time_published": "2022-05-25T00:00:00Z" }, { "url": "https://en.wikipedia.org/wiki/CentrePort%2FDFW%20Airport%20station", "title": "CentrePort/DFW Airport station", "time_published": "2025-12-07T14:04:09Z" }, { "url": "https://en.wikipedia.org/wiki/CentrePort/DFW_Airport_station", "title": "CentrePort/DFW Airport station", "time_published": "2026-05-10T08:51:35Z" }, { "url": "https://faa.gov/air_traffic/publications/atpubs/ntap_jan_31/SC17000.html", "title": "Texas.

The most expensive months are December, June, and July, where average fares climb to roughly $452–$464.", "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.

Booking much further ahead—like 5-6 months—tends to be pricier, averaging over $550, and the same pattern holds for summer and holiday periods, where waiting too long or booking too early both push fares up.", "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline.

A cheaper and popular alternative is the Elizabeth line or Piccadilly line on the Underground, which take longer but offer more stops and lower fares.
