One-stop connections via European hubs open up the entire U.S., including Los Angeles, San Francisco, and Houston. New York and Boston are popular for culture and history, Miami for beaches and Latin American connections, and Chicago for central U.S. access."}, "q1": {"question": "How long is the flight from Lisbon to United States?", "answer": "From Lisbon, non-stop flights to New York take roughly 7½ to 8 hours westbound and about 6½ to 7 hours eastbound. One-stop journeys to Los Angeles or Chicago typically range from 13 to 16 hours total depending on the connection."}, "q2": {"question": "Are there direct flights from Lisbon to United States?", "answer": "Yes, there are non-stop flights from Lisbon to several U.S. cities, mostly operated by TAP Air Portugal and U.S. carriers. Key routes include Lisbon to New York (JFK and EWR), Boston, Miami, Washington D.C. (IAD), San Francisco, and Chicago. Flight times eastbound are typically 7.5 to 9 hours, while westbound flights are longer due to headwinds, often 8.5 to 10.5 hours.

Booking 9–11 weeks ahead typically yields the lowest fares, and midweek departures generally offer better value than weekends, with early-morning or late-evening flights often priced lower than midday departures.", "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. 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."}, "q5": {"question": "How far in advance should I book flights from Lisbon to United States?", "answer": "For flights from Lisbon to the United States, the best time to book is about 9 to 11 weeks before departure, when average fares drop to around $869, though you can often wait a bit closer for shoulder-season travel in April or October when prices are naturally lower.", "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.
