        "question": "What is the typical flight duration from Dallas to San Jose?",
        "answer": "The flight from Dallas to San Jose is about 1,440 miles and typically takes 3 hours 40 minutes nonstop. The return leg is about the same duration, within a few 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.",

        "question": "Are there any direct flights from Dallas to San Jose?",
        "answer": "American Airlines flies nonstop from Dallas/Fort Worth to San Jose, with 85 weekly departures operating daily. The flight takes about 3 hours and 40 minutes, with departures spread throughout the day from mid-morning through late evening. No other carrier offers nonstop service on this 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). 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. 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.",

        "answer": "At San Jose Mineta International Airport, ground transportation includes taxis, ride‑share services (Uber, Lyft), and car rentals, all available at the terminal curbs. The VTA Airport Flyer (Route 60) bus provides direct mass transit to downtown San Jose and connections to the VTA light rail and Caltrain, making it the most used public transit option. Ride‑share is the most popular overall mode, offering the fastest and most convenient access to the city center, with trips typically taking under 15 minutes. Taxis are readily available but are generally more expensive than ride‑share for the short 3‑mile trip.",

        "answer": "Average fares from Dallas to San Jose bottom out around $249 in late January. The cheapest months overall are February (averaging $255), January ($260), and October ($272), while the most expensive stretch is late December at $339. December is the priciest month on average at $322, with April ($294) and March ($292) not far behind.",
        "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.",

        "answer": "For Dallas to San Jose, the optimal booking window is roughly 3 to 6 weeks before departure, with average fares around $195 and the single cheapest day about 25 days out at $188. Booking much earlier or later gets more expensive — prices rise steadily after 6 weeks, hitting $328 if you book 175 days ahead, and they also climb sharply inside 3 weeks, reaching $312 on the day of travel.",
        "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.",

        "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.",

DART's Orange Line light rail runs directly to Terminal A, offering a reliable and affordable option, though the trip can take up to an hour. The Trinity Railway Express (TRE) connects to the airport via a shuttle from CentrePort/DFW station, but it's less direct from downtown. Driving and parking are also available, with multiple on-site garages and economy lots, but this tends to be the priciest choice.",
