With one stop, total travel time often ranges from 10 to 13 hours depending on the connection." }, "q1": { "question": "Are there any direct flights from Lisbon to Boston?", "answer": "Yes, two airlines fly nonstop from Lisbon to Boston: TAP Air Portugal and Delta, both operating daily. TAP runs the most frequencies with up to 26 flights per week (morning and late-afternoon departures), while Delta offers two daily departures. Typical fares on the route run around $909.", "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).

Carrier service and weekly frequencies are summarized 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).

For U.S. citizens, no visa is needed for entry into the U.S. For Portuguese citizens, under the Visa Waiver Program, you can travel to the U.S. for tourism or business for up to 90 days without a visa, but you must obtain an approved ESTA authorization before travel. Travelers of other nationalities should check if they need a visa or qualify for ESTA. For the return from Boston to Lisbon, U.S. citizens can enter Portugal and the Schengen Area visa-free for up to 90 days within any 180-day period.

Taxis and ride shares like Uber and Lyft are readily available at designated pickup areas, offering door-to-door convenience. The Logan Express bus serves Back Bay and several suburbs, and water taxis provide a scenic alternative. Car rentals are on-site at the Rental Car Center.

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.", "toolsUsed": [ "seasonal_prices" ] }, "q5": { "question": "How far in advance should I book tickets from Lisbon to Boston?", "answer": "For the Lisbon to Boston route, the best fares are typically found when booking 6 to 9 weeks before departure, with an average price around $825. During peak summer and holiday periods, demand can push prices higher, so aiming for the earlier end of that window or even a bit sooner may 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.
