The return leg is longer at 8 hours 30 minutes, a difference of 90 minutes due to prevailing winds.", "methodology": "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.", "toolsUsed": ["flight_schedule"]}, "q1": {"question": "Are there any direct flights from New York City to Lisbon?", "answer": "Yes, Delta and TAP Air Portugal both fly non‑stop from JFK to Lisbon. Each operates daily, with Delta offering roughly 7–8 departures a day (mostly between 19:50 and 22:25) and TAP Air Portugal offering 3 daily departures (between 22:00 and 23:00). 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).

The most‑used public transport is the Aerobus shuttle, with two lines running every 20‑25 minutes to the city centre (about 20‑40 minutes) and a 24‑hour ticket costing €4. Public city buses (routes 5, 22, 44, 45, 83) are cheaper but slower. There is no direct train from the airport, but you can take a short taxi ride to Gare do Oriente or Parque das Nações to connect to the Lisbon Metro.

The most expensive months are June, July, and May, where average fares reach $867, $829, and $812.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from New York City to Lisbon?", "answer": "For flights from New York JFK to Lisbon, the best time to book is about 11 to 14 weeks before departure, when average fares are around $760. Booking around 80 days out can yield the absolute lowest fares, around $759, while last-minute tickets typically cost $877 or more. During peak summer and holidays, prices tend to be higher overall, so booking a few weeks earlier than the typical window can help secure a better deal.", "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.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from New York City to Lisbon?", "answer": "Yes, overnight red-eye flights are available nonstop from JFK to Lisbon.

The AirTrain connects all terminals to Jamaica Station for the LIRR and Howard Beach for the A subway line, providing a reliable, traffic-free ride.  Taxis offer a flat fare to Manhattan and are convenient for door-to-door service, though subject to traffic.  Ride-share apps like Uber and Lyft pick up at designated areas outside terminals, with variable pricing.
