        "question": "From which U.S. cities can I fly to Porto?",
        "answer": "Two US cities offer nonstop flights to Porto: New York (EWR) and Boston (BOS). New York has the most service with 64 weekly flights on TAP Air Portugal and United, taking about 6 hours 45 minutes, while Boston has 11 weekly flights on TAP Air Portugal at about 6 hours 40 minutes. Red-eye departures are available from both cities. Travelers elsewhere in the US typically connect through these gateways or European hubs such as Lisbon, London, or Frankfurt. Choose your departure city based on proximity and flight frequency — New York offers far more options each week than Boston.",
        "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.",

From New York, the flight takes about 6 hours 45 minutes, while from Boston it's about 6 hours 40 minutes. Travelers from other US cities can connect through these hubs for one-stop service to Porto.",

        "answer": "The cheapest months to fly from the United States to Porto are typically November and January through March, excluding holiday peaks.

        "question": "How far in advance should I book flights to Porto?",
        "answer": "There is no reliable booking window for flights from the United States to Porto, Portugal, so it's best to book as early as possible, especially for holidays and peak summer periods when fares and availability tighten. As a general rule for international trips, booking two to three months ahead often balances price and choice, though flexibility with dates can help find better deals.",
