        "question": "From which cities in United States can I fly to London?",
        "answer": "You can fly nonstop to London from 30 US cities, with the busiest being New York (JFK), Chicago (ORD), Los Angeles (LAX), Boston (BOS), Dallas (DFW), Atlanta (ATL), San Francisco (SFO), and Miami (MIA). Major carriers on these routes include United, British Airways, Virgin Atlantic, JetBlue, American Airlines, and Delta, with red-eye flights available from most eastern and central hubs. Travelers typically choose their departure city based on proximity and the number of nonstop flights, with New York offering the most at over 700 weekly departures. For those not near a nonstop gateway, one-stop connections are widely available through major US hubs like Chicago, Atlanta, or Dallas, or via European hubs like Dublin or Reykjavik. The best option often balances driving distance to the airport with flight frequency and fare, as larger gateways tend to have more competitive pricing.",
        "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.",
