Tips for this route

- January 2027 is the cheapest month to fly over the next six months, with round trips from $127; September 2026 is the most expensive at $183 and up, a difference of $56 per traveler.
- Departing on a Tuesday averages 21% less than a Sunday on this route. If your dates are flexible, shift the outbound by a day or two and check the calendar view before you book.
- Book 6 to 12 weeks ahead; fares climb in the last three weeks and around holidays.
- Montreal is 2 hours ahead of Denver. Expect to lose 2 hours on the clock heading east, so an overnight or late-afternoon departure tends to arrive at a more usable hour.
Destination guide
Montreal: French North America, 90 minutes from New York
Montreal gives you Europe without the ocean: a walkable French-speaking city of stone streets, terrasses and festivals, reachable in an hour and a half from the Northeast. Air Canada, Porter and the US legacy carriers all compete on the route, so fares stay low.
Best time to visit: June to September is festival season and the terrasses are open — Jazz Fest in late June, Osheaga in August. May and October are cheaper and still pleasant. Winter is genuinely cold but hotel rates fall sharply and the Underground City makes it livable.
