Air Canada launches Columbus-Montreal nonstop, cutting connection times and costs

Air Canada launched daily nonstop service between John Glenn Columbus International Airport (CMH) and Montreal-Pierre Elliott Trudeau International Airport (YUL) on May 1, 2026 — the first-ever direct link between the two airports. The seasonal route runs through October, operated by an Embraer E175, and gives Columbus travelers a direct connection to one of Canada’s largest cities without the layovers that previously added hours and cost to every itinerary.

Columbus is only the third international route from CMH, making this launch unusually significant for Central Ohio. Introductory economy roundtrip fares from $229 are currently available for May and June travel.

Columbus has been waiting for this one. Air Canada activated daily nonstop flights between CMH and YUL on May 1, 2026, ending a situation where every Montreal trip from Ohio’s capital required a connection through Toronto or Chicago — adding up to two and a half hours and, routinely, an extra $100 to $200 in fares.

The route is seasonal, running May through October, and it’s only the third international service operating out of John Glenn Columbus International. That context matters: CMH currently serves Toronto on Air Canada and Cancun seasonally on Southwest. Montreal is a genuine expansion of the airport’s international footprint, not a reshuffling of existing capacity.

For Central Ohio business travelers, the timing aligns with a regional economy that has been pulling in Canada-facing industries — tech, biotech, and manufacturing — at a pace that connection-dependent itineraries were struggling to serve. The route also carries a practical bonus: YUL offers US preclearance, meaning passengers clear US customs and immigration in Montreal before departure, arriving back in Columbus as a domestic arrival.

Introductory economy roundtrip fares are available from $229 as of early May, with Aeroplan award availability at 10,000 points roundtrip still showing for select dates. Neither will last through summer.

What the CMH-YUL launch actually changes for Columbus travelers

Before May 1, reaching Montreal from Columbus meant choosing between Air Canada connections through Toronto Pearson (YYZ) — 14 times weekly on A220-300s — or United connections through Chicago O’Hare (ORD), operating 21 times weekly on Boeing 737-900s with layovers averaging two and a half hours. United offered the lowest fares on that corridor; Air Canada offered the smoother Star Alliance award redemption. Neither offered a nonstop.

The new service cuts connection time out of the equation entirely. Air Canada‘s on-time performance on comparable short-haul routes runs at 82%, versus 78% for United’s ORD connections — a gap that feels small until a tight connection turns a day trip into an overnight.

Official schedule data confirms daily frequency for the May–October 2026 season. The Air Canada schedule page shows CMH-YUL operating seven days a week through the seasonal window. Columbus travelers connecting onward from Montreal gain access to Air Canada’s transatlantic network — a meaningful upgrade for anyone routing to Europe who previously had to build their itinerary around Toronto or Chicago.

A $2 billion replacement airport is under construction in Columbus, with an anticipated opening in 2029. The CMH-YUL launch is the kind of route that tends to accelerate that pipeline: demonstrated international demand gives airport planners and airlines a data point to justify further expansion. For those curious about securing launch fares for new routes before introductory pricing disappears, the window here is measured in weeks, not months.

Why Air Canada keeps picking Midwest cities — and what it signals

This is not the first time Air Canada has opened a Midwest US city with a single daily A220 and watched it perform. The airline launched CMH-YYZ on May 15, 2024, using the same playbook: daily service, A220 equipment, a Midwest market with suppressed direct demand. That route hit an 85% average load factor in its first year and lifted CMH international passenger numbers by 12%, according to Columbus Airport Authority’s 2025 report. The economic impact was assessed at $50 million. Air Canada has repeated this pattern across three Midwest launches since 2022.

The CMH-YUL launch fits the same template. Industry reports indicate that pre-launch origin-and-destination traffic between Columbus and Montreal — passengers making the trip via connections — pointed to meaningful suppressed demand that a nonstop would unlock. Historical data suggests comparable corridors see a 20–30% traffic uplift when connections are replaced by direct service.

Montreal itself adds a dimension Toronto doesn’t: it’s a distinct cultural and linguistic market, draws different business travel (aerospace, pharma, gaming), and sits at the center of Air Canada’s transatlantic hub network. Columbus travelers who previously routed through Chicago to reach Europe now have a cleaner option.

Air Canada also recently launched Montreal–Santo Domingo nonstop service, reinforcing YUL’s role as a hub for new international connections — which expands the onward network available to CMH passengers connecting through Montreal.

How to book CMH-YUL before summer pricing takes over

Introductory fares are available now, but the CMH-YUL corridor will price up as summer demand builds — the window for sub-$250 economy roundtrips is likely measured in days, not weeks.

• Book economy RT fares now for May 15–June 15: Introductory pricing from $229 roundtrip is verified as of May 2, 2026, on aircanada.com. Search directly — third-party OTAs are slower to reflect launch fares on new routes.
• Check Aeroplan award availability immediately: 10,000 points roundtrip CMH-YUL award seats are available for select dates. Log into aircanada.com/awards and search May–June before summer sellout. Aeroplan sweet spots on short-haul US-Canada routes disappear fast once a route gains visibility.
• Use YUL preclearance on the return: Clear US customs and immigration in Montreal before boarding. You arrive in Columbus as a domestic passenger — no federal inspection queue, no baggage claim delay. Factor this into tight same-day itineraries.
• Consider September–October for value travel: Fares historically dip to around $220 roundtrip in the shoulder season. Montreal in fall is a different city — quieter, cheaper, and still fully operational before the seasonal route closes.
• Set a Superdeal alert on the CMH-Canada corridor: Air Traveler Club’s tracking has flagged sub-$200 roundtrip promos on this corridor before. Alerts fire when anomalies appear — typically lasting three to seven days.

Watch: Air Canada’s Q2 2027 load factor report will be the first real signal of whether CMH-YUL becomes a year-round permanent route or stays seasonal. An average above 80% almost certainly triggers a winter extension and additional capacity.
