        "question": "From which cities in United States can I fly to San Francisco?",
        "answer": "San Francisco is served by nonstop flights from 80 US cities, with the busiest departures from Los Angeles (LAX), San Diego (SAN), Seattle (SEA), New York (JFK), and Chicago (ORD). These nonstop routes are operated by a mix of carriers including United, American, Delta, Southwest, Alaska, and JetBlue, with flight times ranging from under 100 minutes for nearby West Coast cities to over six hours from the East Coast. For travelers not near a nonstop gateway, one-stop connections are widely available through major hubs like Denver, Dallas, or Atlanta. Choosing a departure city usually comes down to proximity—travelers in Southern California often pick LAX or SAN for the shortest flights, while those in the Northeast or Midwest rely on their nearest large airport with frequent service, balancing convenience against the total travel time.",
        "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.",
