        "question": "What is the typical flight duration from Washington D.C. to Montreal?",
        "answer": "A nonstop flight from Washington, D.C. (IAD) to Montreal (YUL) typically takes about 1 hour 45 minutes. There is usually no significant difference in duration on the return flight. With one stop, common layovers include New York or Toronto, bringing total travel time to around 4 to 5 hours. Airlines such as Air Canada and United offer nonstop service with similar flight times."

      "q2": {
        "question": "Are there visa requirements to travel from Washington D.C. to Montreal?",
        "answer": "Yes, visa requirements apply for travel from Washington D.C. to Montreal. U.S. citizens do not need a visa for tourist visits up to 180 days but must carry a valid passport. U.S. lawful permanent residents need an Electronic Travel Authorization (eTA) when flying to Canada, unless they hold a valid U.S. Green Card, in which case they are exempt. Other nationals should check Canada's visa requirements based on their citizenship. Travelers returning to the U.S. from Canada must meet U.S. re-entry requirements, which may include a visa for non-U.S. citizens."

      "q3": {
        "question": "What are the ground transportation options in Montreal?",
        "answer": "Montréal-Pierre Elliott Trudeau International Airport (YUL) connects to downtown Montreal via multiple ground transport options. The 747 Express Bus operated by the STM is the most used, running 24/7 to central stops like Lionel-Groulx and Berri-UQAM metro stations in about 45–60 minutes. Taxis and ride-share services like Uber are available at fixed rates, taking around 20–30 minutes to downtown without heavy traffic. Car rentals are accessible on-site but are more practical for exploring beyond the city. The upcoming REM light rail will eventually offer a direct train link, but for now the 747 bus remains the best balance of cost and convenience for most travelers."

      "q4": {
        "question": "When is the cheapest time to fly from Washington D.C. to Montreal?",
        "answer": "Based on seasonal price data for flights from Washington D.C. (IAD) to Montreal (YMQ), the cheapest months to fly are August (average $425), July ($430), and September ($470), while the most expensive months are November (average $565), December ($521), and January ($508).",
        "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.",

        "question": "How far in advance should I book tickets from Washington D.C. to Montreal?",
        "answer": "For flights from Washington D.C. to Montreal, the optimal booking window is about 10 to 13 weeks before departure, with average fares around $389. The absolute lowest price appears around 90 days out, while last-minute bookings can cost nearly double. During peak summer or holiday periods, booking even earlier—up to 3-4 months ahead—is advisable to secure the best rates.",
        "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.",

        "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. 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.",

Montréal Saint‑Hubert is farther from the city centre, mainly handling regional and charter flights, so Trudeau is the convenient choice for most travellers."

Connecting itineraries most often use the same regional jets on the Montreal-bound leg, with common connections through Toronto (YYZ) where the longer segment may be flown by Airbus A320-family, A220, or occasionally Boeing 787 aircraft. Specific aircraft can vary by day and airline, and while many modern planes offer Wi-Fi and seatback entertainment, availability is not guaranteed on every flight.",
