      },
      "q1": {
        "question": "Are there any direct flights from Lisbon to Newark?",
        "answer": "Yes, TAP Air Portugal and United both fly nonstop from Lisbon to Newark. Together they offer 41 weekly flights, with TAP operating 27 and United 14, and both carriers run daily service.",
        "methodology": "Airlines and weekly frequencies 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).

Rental cars are located at a consolidated center accessible via the AirTrain, and authorized shuttle services also operate from the airport.",

        "question": "When is the cheapest time to fly from Lisbon to Newark?",
        "answer": "The cheapest months to fly from Lisbon to Newark are November, October, and April, with average fares around $634–$651, while the most expensive are June, July, and May, where prices climb to $812–$867 on average.",
        "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

      },
      "q5": {
        "question": "How far in advance should I book tickets from Lisbon to Newark?",
        "answer": "For Lisbon to Newark, the best fares typically appear when booking about 10 to 13 weeks ahead, with an average price around $760. For summer or holiday travel, booking toward the earlier end of that window or even a bit further out can help avoid higher last-minute fares, which can climb above $870.",
        "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.",

        "answer": "No overnight (red‑eye) flights operate from Lisbon to Newark — neither nonstop nor connecting itineraries with a red‑eye long leg are scheduled on this route.",
        "methodology": "Red-eye flights are identified from scheduled local departure and arrival times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes — flagging services that depart late at night and arrive the following morning; for connecting itineraries the red-eye is based on the timing of the overnight long-haul leg.",

        "question": "Which airlines usually operate this route from Lisbon to Newark?",
        "answer": "TAP Air Portugal and United operate non‑stop from Lisbon to Newark. TAP flies up to 27 times a week with multiple daily departures and a median fare around $689, while United offers 14 weekly flights at a median of about $660.",
        "methodology": "Airlines and weekly frequencies 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).

      },
      "q9": {
        "question": "How reliable are on‑time departures on this route from Lisbon to Newark?",
        "answer": "Departures are generally reliable, though afternoon flights face a higher risk of delays. Early morning options, particularly on TAP Air Portugal, typically offer the best punctuality."
      },
      "q10": {
        "question": "Which months have the best weather for traveling to Newark?",

      },
      "q12": {
        "question": "Which airport should I use in Newark?",
        "answer": "Newark Liberty International Airport is the only commercial airport in Newark. It is located about 3 miles south of downtown Newark and 15 miles southwest of Midtown Manhattan, serving as a major hub for United Airlines and a focus city for low-cost carriers like Spirit and JetBlue."
      },
      "q13": {
        "question": "How do I get to Humberto Delgado Airport from the city center?",
        "answer": "From central Lisbon, the Aerobus shuttle (Lines 1 and 2) is the most popular direct option, running every 20–25 minutes and taking about 25–40 minutes; tickets are 24-hour passes. Public buses (such as 5, 22, 44, 45, and 83) are the cheapest way to reach Humberto Delgado Airport, though they make more stops. Taxis and ride‑share services are available at ranks outside Arrivals and Departures, offering the fastest door‑to‑door trip (around 15–20 minutes) but at a higher cost, with a standard airport surcharge. Driving and parking are possible, but the airport is surrounded by urban areas and parking can be expensive.",
