Montreal's Connectivity at a Glance

Montreal-Trudeau (YUL) tracks 25 destinations, and 15 of them — 60% — carry a verified historical direct-service record in the OpenFlights dataset, a higher share than several larger Canadian airports covered here. All 4 domestic connections are verified, and so are 9 of Montreal's 10 U.S. routes and 2 of its 6 UK pairs.

The pattern tracks distance and region more cleanly than most of the cities in this batch: verification is close to universal within Canada and the northeastern U.S., stays reasonably strong out to the West Coast and to London, then drops to zero for all 5 Australian pairs, the most distant destinations tracked from Montreal. Read Montreal's network almost like a gradient: the closer and more established the market, the more likely this dataset has a documented direct flight behind it, and the one break in that pattern, Seattle, is worth flagging on its own rather than assuming it follows the rest of the U.S. list.

Domestic Connections from Montreal

Montreal's 4 domestic connections — Ottawa, Toronto, Calgary and Vancouver — are all verified, ranging from a 12-minute hop to Ottawa up to a 4.3-hour transcontinental run to Vancouver.

International Connections from Montreal

Montreal's 21 international pairs split unevenly by region: 9 of 10 U.S. routes are verified, with Seattle the lone exception, and London Heathrow and Gatwick both carry a verified record while the other 4 UK cities and all 5 Australian pairs don't. Treat the Australia entries here as distance and time-zone references only; none show documented nonstop service, and any real itinerary would route through the U.S., Asia or the Gulf.

Notable Verified Routes

15 of Montreal's 25 tracked routes carry a verified historical operating record, led by dense domestic and U.S. corridors like Toronto and New York where 6 or more carriers show up. The 5 Australian pairs are the one block with zero verified routes.

Looking Up Montreal Routes Across GDS Systems

YUL works as the origin code in an Amadeus, Sabre, Galileo or Apollo availability search the same way regardless of destination. For the unverified entries, particularly the Australia and secondary UK pairs, run a live check before assuming a routing, since this dataset is a historical snapshot rather than today's schedule.

Amadeus:  AN15JULYULxxx
Sabre:    A15JUNYULxxx
Galileo:  A/15JUNYULxxx

Replace xxx with the destination's own 3-letter IATA code from the tables above — the availability-check syntax itself doesn't change by destination, only the city pair does.
