        "question": "What is the typical flight duration from Washington to Los Angeles?",
        "answer": "The flight from Washington Dulles to Los Angeles is about 2,280 miles and typically takes 5 hours 31 minutes westbound, while the return is about 28 minutes shorter at 5 hours 3 minutes eastbound.",
        "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.",

Rideshare and taxis are the most-used options, offering door-to-door convenience in roughly 30–60 minutes depending on traffic. The FlyAway bus provides a direct, fixed‑price connection to Union Station ($12.75) and Van Nuys, while Metro rail is accessible via a free shuttle to the LAX/Metro Transit Center. Rental cars are widely available but often slower due to freeway congestion. For the fastest trip, rideshare or taxi is typically best outside peak hours.",

        "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.",

        "answer": "For Washington (IAD) to Los Angeles (LAX), the best fares come when booking about 5–8 weeks before departure, averaging $278, with the single cheapest day around 55 days out at $277. Booking last-minute drives prices up to around $360, while booking more than 4 months ahead also costs more. This pattern holds for most of the year, though summer and major holidays tend to push the optimal window slightly earlier and raise fares across the board.",
        "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. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window.

Hollywood Burbank Airport is smaller, closer to Hollywood and the San Fernando Valley, and convenient for domestic flights on airlines like Southwest. Long Beach Airport offers a relaxed experience with limited service, mainly on Southwest, and is closest to coastal attractions. Ontario International is farther east, good for the Inland Empire, with domestic flights on several carriers."

Taxis (Washington Flyer) and ride‑share services like Uber and Lyft are available 24/7 and are the most popular and fastest options, though they are more expensive. Shared van services like SuperShuttle offer door‑to‑door service for a mid‑range cost. Driving and parking is also an option, with economy lots at $15 per day and a free shuttle to the terminal.",
