Louisville is getting its first international passenger flights. Mayor Craig Greenberg announced that Air Canada will begin nonstop service between Louisville and Toronto starting in spring, with the route eventually running daily once fully ramped up.
Starting this spring with Air Canada, Louisville will have daily nonstop international flights to Toronto, Greenberg said in a post on X
. Air Canada's own announcement, detailed in a release via

, confirms the carrier will launch new service between Toronto and Louisville in summer 2027, with flights beginning in late April before increasing to daily service in May.
Not every account of the launch lines up perfectly. A separate report from simpleflying.com pegs the first departure for Wednesday, April 28, 2027, but describes the route as a four-weekly operation using Jazz Aviation's 76-seat CRJ900 aircraft rather than daily service from day one. That outlet also notes this will be Louisville's first Air Canada service since flights were last available in 2002, and that the Toronto-Louisville route covers 431 nautical miles, or 798 kilometers, each way.
No International Terminal, But Plenty of Demand
There's a catch: Louisville Muhammad Ali International Airport currently only has international service for cargo, according to Engineering News-Record. The airport has never offered international passenger service before, which is part of why the Air Canada announcement is such a milestone for the city.
To catch up, the airport is planning a new 60,000-square-foot international concourse as part of the multiyear, $1 billion SDF Next capital improvement program, the trade publication reports. The new concourse will include four dual-use jet bridges, designed to handle both domestic and international flights. Bidding on the project is scheduled for November, with construction expected to begin in January and take about three years, per the same account — though WDRB has described the construction start as merely possible in January, also estimating roughly three years to complete.
Airport CEO Dan Mann has said demand is strong enough that service should arrive right as the facility is ready. The day it opens we will have international service, that's how much demand there is, Mann told WDRB. WDRB also reports that air service out of Louisville has increased 40% since 2018.
The Numbers Behind the Route
Simpleflying.com's booking data indicates that 16,300 round-trip passengers already traveled indirectly between Toronto and Louisville in 2025, suggesting built-in appetite for a direct option. The new nonstop route is also part of a larger structure: Air Canada's Transborder Joint Business Agreement with United Airlines supports more than 1,200 connecting itineraries, according to the globenewswire.com release.
Louisville Muhammad Ali International Airport has continued to serve passengers even without international passenger flights. The airport handled 4.59 million total passengers in 2025, its third-busiest year ever, according to the airport's own account, which also notes eight airlines served more than 40 nonstop destinations from Louisville in 2025, with 19 of those routes increasing capacity and eight growing by double digits.
Cargo and Jobs Still Drive the Airport's Economic Weight
Cargo remains a major piece of the airport's identity even as passenger service expands. SDF handled nearly 7.5 billion pounds of cargo in 2025, more than 13% above the previous year, the airport reported. A separate assessment found the airport and related activities handled more than 6.9 billion pounds of cargo and ranked as the third-busiest cargo airport in North America and fifth in the world.
The broader economic footprint is substantial. Airport and airport-related activities generate $12.8 billion in annual economic impact and $550 million in state and local tax revenue, and nearly 90,000 Louisville Metro jobs — roughly 1 in 8 jobs in the metro area — can be attributed to airport operations, per the airport's own figures. A prior assessment covering the two Louisville airports in 2024 found $12.8 billion in economic output, 89,357 direct and indirect jobs, and $551.1 million in state and local tax revenues, up 23% in output and more than 21% in tax revenue compared with the previous report covering 2018. More than $1 billion is planned for the SDF Next program overall, with more than $565 million in additional investment expected through 2028.
For now, Louisville's international ambitions ride on a single new route and a concourse whose project document was expected to be bid out in November. Whether the Air Canada flights launch daily or four times weekly, and whether the new terminal infrastructure is ready in time, remain unsettled.
