        "question": "From which cities in United States can I fly to Chicago?",
        "answer": "You can fly to Chicago from 160 U.S. cities, with the busiest nonstop gateways including New York (LGA), Denver, Kansas City, Boston, Detroit, Las Vegas, Phoenix, and Minneapolis.

        "methodology": "The US departure cities with nonstop service to this destination, their weekly flight frequencies, typical flight times, airlines, and red-eye availability 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 identify every US airport with scheduled nonstop service to the destination, group them into their metropolitan areas, and rank the cities by scheduled weekly departures; the typical flight time is the median scheduled duration, and red-eye availability is flagged from scheduled local departure and arrival times.",
