        "question": "From which cities in United States can I fly to Chicago?",
        "answer": "You can fly nonstop to Chicago from 160 US cities, with the busiest being New York (over 1,170 weekly flights), Denver, Kansas City, Boston, and Detroit. Major airlines like United, American, Southwest, and Delta operate these routes, with flight times ranging from about one hour from nearby cities like Grand Rapids to over four hours from the West Coast. Because service is so widespread, most travelers simply fly nonstop from their nearest airport; one-stop connections via hubs like Atlanta or Dallas are only needed from smaller cities without direct options. Red-eye flights are available from most major gateways for late-night arrivals.",
        "methodology": "The U.S. departure cities with nonstop service to this destination and their weekly frequencies 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). We identify every U.S. airport with scheduled nonstop service, group airports into their metropolitan areas, and rank cities by scheduled weekly departures.",
