        "question": "What is the typical flight duration from Chicago to Montréal?",
        "answer": "The flight from Chicago to Montréal is about 750 miles and typically takes 2 hours 15 minutes nonstop. The return leg is longer at about 2 hours 40 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.",

        "answer": "From Montréal-Trudeau Airport (YUL), the 747 Express bus is the most-used option, running 24/7 to downtown for a flat $11 fare in about 45–70 minutes. Taxis offer a faster, door-to-door ride with a fixed fare of $49.45 to downtown (5 a.m.–11 p.m.) or $56.70 overnight. Ride-share services like Uber and Lyft are also available, with designated pickup zones. Car rentals are on-site, and a light-rail link (REM) is under construction for future service. The 747 bus is generally the best value, while taxis are quickest.",

        "question": "When is the cheapest time to fly from Chicago to Montréal?",
        "answer": "The cheapest time to fly from Chicago to Montréal is late summer to early fall, with September averaging $281 and October $282, while the most expensive months are December ($338), June ($329), and July ($328).",
        "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 Chicago to Montréal?",
        "answer": "For flights from Chicago to Montréal, booking roughly 4-6 weeks before departure yields the best fares, averaging about $234, with the single cheapest day being 30 days out at $233. Booking much earlier (e.g., 180 days ahead, around $350) or last-minute (0-5 days, around $277) costs noticeably more. For summer and holiday periods, demand spikes push prices up, so aiming for the earlier end of that window — closer to 6 weeks out — is advisable.",
        "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.",

        "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). 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.

        "question": "How do I get to Dupage County from the city center?",

Shuttle buses and regional buses also serve the airport, while taxis, limos, and ride‑share services offer door‑to‑door convenience. Driving and parking are available with hourly, daily, and economy lots, though traffic can be heavy.",
