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. 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": [ "route_airlines", "flight_schedule", "redeye_flights" ] }, "q3": { "question": "What are the ground transportation options in Montréal?", "answer": "From Montréal-Trudeau International Airport (YUL), the main options to downtown are taxi, ride share (Uber, Lyft), public transit via the STM 747 bus line, hotel/regional shuttles, limousines, and the Air Canada City Shuttle. Taxis charge a fixed fare of $49.45 during the day and $56.70 overnight, making them a predictable and popular choice. The 747 express bus is the most-used public transit option, connecting the airport to downtown and key transit hubs. Ride share services like Uber and Lyft are readily available and generally considered convenient, with pickup zones at the terminal.

The absolute sweet spot is about 30 days out at $233, while booking far in advance — say 5 to 6 months ahead — can push prices up to $350. For summer and holiday travel, you'd want to book on the earlier side of that window, since demand tends to raise fares sooner.", "methodology": "Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive.
