        "question": "What is the typical flight duration from London to Seattle?",
        "answer": "The flight from London to Seattle covers about 4,790 miles. Nonstop flights typically take 10 hours 16 minutes outbound, with the return leg to London being about 8 hours 25 minutes — the westbound journey is notably longer due to prevailing winds.",
        "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.",

An ESTA electronic travel authorization is required before travel.\n\nThis is general guidance to help you plan, not official immigration advice — entry rules can change and can depend on your nationality and circumstances, so please confirm the current requirements with the relevant embassy or official government source before you travel.",

The Link light rail is the most-used and often fastest option, providing frequent service to downtown Seattle. Rideshare and taxis are also popular for door-to-door convenience, while rental cars offer flexibility for exploring the region. A shared door-to-door shuttle service is available for those preferring a more economical ride.",

The Elizabeth line offers another rail alternative in under 45 minutes, and coaches run to Victoria and other UK destinations. Black cabs or pre-booked minicabs are available curbside, though travel by car takes at least an hour and driving yourself means paying congestion and ULEZ charges.",
