        "question": "What is the typical flight duration from Houston to Seattle?",
        "answer": "The flight from Houston (IAH) to Seattle (SEA) is about 1,870 miles and typically takes 4 hours 47 minutes. On the return, the flight is shorter at 4 hours 21 minutes because of prevailing tailwinds.",
        "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 Houston to Seattle?",
        "answer": "Yes, United and Alaska Airlines fly nonstop from Houston (IAH) to Seattle. United runs up to 13 daily departures and Alaska up to 6, both operating daily year-round. The flight takes about 4 hours 47 minutes westbound, with typical round-trip fares around $234–$278.",
        "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. Aircraft types are taken from the equipment each operating carrier schedules on this route, drawn from published airline timetables and airline equipment schedules in our flight-schedule database. They describe typical scheduled aircraft and can vary with seasonal or day-of-week assignments and last-minute equipment swaps.",

        "question": "What are the ground transportation options in Seattle?",
        "answer": "Seattle–Tacoma International Airport sits about 14 miles south of downtown Seattle. The Link light rail is the most-used option for reaching the city center — the station is connected to the terminal via a walkway on the fourth floor of the parking garage, and the ride to downtown takes roughly 40 minutes with a stop at Westlake Station. Taxis (metered) and rideshare services like Uber and Lyft pick up on the third floor of the parking garage and offer a faster but pricier trip, typically 30–45 minutes depending on traffic. Rental cars are available from an off-site facility served by free 24/7 shuttle buses, while King County Metro buses stop on International Boulevard near the light rail station. For most travelers going downtown, Link light rail is both the fastest and most heavily used option.",

        "answer": "Average fares from Houston to Seattle bottom out around $325 in late January, making that the single cheapest stretch to fly. The cheapest months overall are October at $337, January at $338, and February at $351, while the most expensive period is late June, when average fares climb to $456. July and June are the priciest months at $442 and $441 respectively.",
        "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.",

        "question": "How far in advance should I book tickets from Houston to Seattle?",
        "answer": "For flights from Houston to Seattle, book roughly 4 to 6 weeks ahead of departure to get the best fare, with average prices around $296 in that window. The absolute cheapest day to book is about 30 days out, at roughly $292, while booking very far in advance such as 180 days ahead can cost closer to $432. Summer and holiday periods tend to push optimal booking earlier, so aim for the upper end of that window, around 6 weeks out, during those times.",
        "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.",

        "question": "Which airport should I use in Seattle?",
        "answer": "Seattle has two airports. Seattle‑Tacoma International is the primary airport, 14 miles south of downtown, serving most domestic and international airlines and alliances.

The 500 IAH Downtown Direct bus offers a cheaper public transit alternative, while driving and parking yourself is convenient with on‑site garages and economy lots.
