        "question": "What is the typical flight duration from Newark to Lisbon?",
        "answer": "The nonstop flight from Newark to Lisbon takes about 7 hours, covering approximately 3,380 miles. The return leg is longer, typically around 8 hours and 35 minutes, due to prevailing winds.",
        "methodology": "Flight times and distances 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). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.",

        "question": "Are there any direct flights from Newark to Lisbon?",
        "answer": "Yes, TAP Air Portugal and United both fly nonstop from Newark to Lisbon. TAP runs up to 41 flights a week with departures spread throughout the day (including a late-night 23:00), while United offers 21 weekly flights with evening departures around 20:25–21:30. Both carriers operate daily, so you can fly any day of the week; the flight takes about 7 hours eastbound.",
        "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). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.",

        "answer": "Lisbon Airport offers several solid ground transportation options into the city center. The fastest and most-used choice is the metro, which connects directly from the Aeroporto station on the red line and reaches downtown in about 20 minutes. Taxis are available 24/7 outside arrivals and take roughly 15 minutes, while Carris city buses and shuttles serve the center and nearby areas. Car rental and valet services are also available at the airport for those who prefer to drive.",

        "question": "When is the cheapest time to fly from Newark to Lisbon?",
        "answer": "Average fares from Newark to Lisbon bottom out around $331 in late September, with September and October the cheapest months overall at roughly $342–346. February is also relatively affordable at about $365, while the most expensive stretch is late December, when average prices climb to $463. December as a whole is the priciest month at $436, followed by July at $426.",
        "methodology": "Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.",

        "question": "How far in advance should I book tickets from Newark to Lisbon?",
        "answer": "For Newark to Lisbon, book roughly 4 to 7 weeks before departure for the lowest fares, which average around $315. Prices stay fairly flat from about 25 to 55 days out, then climb noticeably for bookings made more than 3 months ahead or within a couple of weeks of travel. For summer or holiday periods, aim toward the earlier end of that window, since demand pushes fares higher close to departure.",
        "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.",

        "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.",

      "q13": {
        "question": "How do I get to Liberty Intl Airport from the city center?",
        "answer": "From downtown Newark or New York City, the fastest and most popular option is the NJ Transit train from New York Penn Station or Newark Penn Station to the Newark Airport Rail Station, then the AirTrain monorail to your terminal, taking about 30 minutes from Midtown Manhattan. A cheaper but slower option is the CoachUSA Newark Airport Express bus from Port Authority Bus Terminal or other stops, which takes about 50 minutes and serves every terminal. Ride-sharing apps like Uber and Lyft offer convenient door-to-door service, while licensed taxis are available at each terminal; driving yourself is possible with on-airport parking or the free cell phone lot for pickups and drop-offs. Public transit is generally the most cost-effective, while taxis and ride-shares are pricier but more direct.",
