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.", "toolsUsed": [ "flight_schedule" ] }, "q1": { "question": "Are there any direct flights from Houston to Lisbon?", "answer": "There are no nonstop flights from Houston Hobby (HOU) to Lisbon.

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.", "toolsUsed": [ "route_airlines", "flight_schedule" ] }, "q3": { "question": "What are the ground transportation options in Lisbon?", "answer": "From Lisbon Airport, the Aerobus shuttle (lines 1 and 2) is the most popular and efficient option, reaching the city center in 20–40 minutes with 24-hour passes costing €4 for adults. Public city buses (numbers 5, 22, 44, 45, 83) are the cheapest way to reach various neighborhoods, while taxis are available at ranks outside Arrivals but come with a standard airport surcharge and luggage fees.

Booking too far ahead can actually cost more, with prices climbing above $450 if you book 95 or more days in advance. For summer and holiday travel, demand tends to push the ideal window a bit earlier, so aim for 6 to 10 weeks ahead during those peak periods.", "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive.
