        "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. Carrier service and weekly frequencies are summarized 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). Where available, on-time and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, and typical fares from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "question": "What are the ground transportation options in Sendai?",
        "answer": "Sendai Airport is connected to the city center primarily by the Sendai Airport Access Line train, which reaches Sendai Station in as little as seventeen minutes on rapid services and about twenty-five minutes on local trains. This train is the most used and recommended option due to its speed, frequency, and reliability. Buses also operate to Sendai Station and other key areas, taking around forty minutes, though they are less frequent. Taxis are available outside the terminal and take roughly forty minutes to the city center, offering convenience but at a higher cost. Ride-share services are not widely used in Japan, and traditional taxis are the main on-demand option. Car rentals are available at the airport for travelers planning to explore the Tohoku region, but they are less practical for city-center trips due to limited parking and traffic. Overall, the train is the best balance of efficiency and affordability."

        "question": "Are overnight (red‑eye) flights available from Ryukyu Islands to Sendai?",
