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.", "toolsUsed": ["flight_schedule"]}, "q3": {"question": "What are the ground transportation options in Montréal?", "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.", "toolsUsed": [], "references": [{"url": "https://yulsatisfaction.admtl.com/hc/en-ca/articles/29089144643357-How-much-does-a-taxi-ride-cost", "title": "How much does a taxi ride cost? – Montreal-Trudeau International Airport", "time_published": "2025-09-12T15:26:23Z"}, {"url": "http://yulsatisfaction.admtl.com/hc/en-ca/categories/360000103337-Ground-Transportation", "title": "Ground Transportation – Montreal-Trudeau International Airport", "time_published": "2019-01-01T00:00:00Z"}, {"url": "https://en.wikipedia.org/wiki/Montréal–Trudeau_International_Airport", "title": "Montréal–Trudeau International Airport", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-07-17T16:57:08Z"}, {"url": "https://en.wikipedia.org/wiki/Transportation%20in%20Montreal", "title": "Transportation in Montreal", "time_published": "2026-03-15T16:43:15Z"}, {"url": "https://yulsatisfaction.admtl.com/hc/en-ca/articles/30293241484829-Do-you-offer-an-assistance-between-the-drop-off-zone-and-the-terminal-at-YUL", "title": "Do you offer an assistance between the drop-off zone and the terminal at YUL? – Montreal-Trudeau International Airport", "time_published": "2025-09-12T17:53:20Z"}]}, "q4": {"question": "When is the cheapest time to fly from Chicago to Montréal?", "answer": "The cheapest months to fly from Chicago to Montréal are April, September, and August, with average fares around $366, $387, and $389. The most expensive months are June, July, and December, when average prices climb to $504, $473, and $446.", "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.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Chicago to Montréal?", "answer": "For flights from Chicago to Montréal, the best fares are typically found when booking 7 to 10 weeks ahead, with the absolute lowest price around $388 about 55 days before departure. During peak summer and holiday periods, demand pushes prices higher, so you should book closer to the early end of that window — roughly 8 to 10 weeks out — to secure a reasonable fare.", "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.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Chicago to Montréal?", "answer": "No overnight (red-eye) flights are scheduled from Chicago to Montréal — neither nonstop red-eyes nor connecting itineraries with a red-eye long leg operate on this route.", "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.", "toolsUsed": ["redeye_flights"]}, "q7": {"question": "Which airlines usually operate this route from Chicago to Montréal?", "answer": "United, Air Canada, and American all fly nonstop from Chicago O'Hare to Montréal, with United operating up to 77 weekly flights, while Air Canada and American each offer 63.
