        "question": "What is the typical flight duration from Boston to Portland?",
        "answer": "The flight from Boston to Portland covers about 2,530 miles and typically takes 6 hours and 13 minutes. On the return, the trip is shorter at 5 hours and 23 minutes, with the westbound leg being longer 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.",

        "question": "Are there any direct flights from Boston to Portland?",
        "answer": "Alaska Airlines and JetBlue both fly nonstop from Boston to Portland daily, with a combined 67 weekly flights. Alaska operates up to seven departures a day — a mix of early-morning and late-afternoon/evening — while JetBlue offers three daily departures in the morning and evening. The nonstop flight takes about 6 hours 13 minutes westbound and roughly 5 hours 23 minutes on the return.",

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.

The most-used and fastest option is the MAX Red Line light rail, which connects directly to the city center in roughly 40 minutes. Taxis, ride shares like Uber and Lyft, and rental cars are also available, but the light rail is generally preferred for its reliability and low cost.",

        "methodology": "This seasonal price baseline is a 365-day daily curve of typical round-trip fares for the route, precomputed monthly in-house from Priceline's own air booking-summary archive (the same data that backs the site), not a third party. For each calendar day we take a representative round-trip fare — a blend of the 25th-percentile and average ticket price over the route's bookings — and Gaussian-smooth the series so it reads as a clean seasonal trend rather than day-to-day noise. Thin and international routes are neighbor-filled: the seasonal shape is borrowed from the nearest dense routes (by origin-and-destination great-circle distance) with the price level anchored to the route's own bookings, so a sparse route still shows a plausible curve. It reflects current fares and is refreshed monthly.",

      "q5": {
        "question": "How far in advance should I book tickets from Boston to Portland?",
        "answer": "For Boston to Portland, the best fares come when booking roughly 4-6 weeks before departure, with average prices around $291; the single cheapest day to book is about 30 days out at $289. Booking more than 16 weeks ahead tends to cost more (over $400), and prices also rise steeply within the final two weeks before travel. For summer and holiday periods, demand pushes the ideal window earlier—likely 8-12 weeks ahead—since peak dates sell out sooner and fares climb faster.",
        "methodology": "This booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. It expresses the typical round-trip fare as a function of how many days before departure a trip is booked — from about 180 days out down to the day of departure — aggregating the route's bookings by advance-purchase days and Gaussian-smoothing the curve the same way as the seasonal baseline. From that curve we highlight the stretch of lead times with the lowest average fare as the suggested booking window. Thin and international routes are neighbor-filled from the nearest dense routes, with the price level anchored to the route's own bookings. 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.",

        "question": "How do I get to Logan Intl Airport from the city center?",
        "answer": "From downtown Boston, the fastest and most popular way to reach Logan Airport is the MBTA Silver Line SL1 bus, which runs frequently from South Station and is free from the airport to downtown. The Blue Line subway is another economical option, connecting to a free shuttle bus at Airport Station. Ride-share services like Uber and Lyft, as well as taxis, provide door-to-terminal convenience at a higher cost. Logan Express buses from Back Bay offer a comfortable ride, while driving and parking at the airport is possible but expensive and often congested.",
