        "question": "From which cities in United States can I fly to Philadelphia?",
        "answer": "Philadelphia is served by nonstop flights from 88 cities across the United States, with the most frequent departures from Atlanta, Harrisburg, Boston, Chicago, and Albany. Major hubs like Atlanta, Chicago O'Hare, Denver, Dallas/Fort Worth, and Detroit offer multiple daily flights on carriers such as American, Delta, United, and Southwest, while smaller regional airports like Harrisburg, Albany, and State College provide quick connections primarily on American. Travelers typically choose their departure city based on proximity and flight availability—those near a major hub enjoy more frequency and airline choice, whereas those in smaller markets may rely on a single carrier with convenient schedules. For most origins, the flight is under three hours, with the shortest hops from Harrisburg and State College taking about an hour.",
        "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.",
