Air Transat has begun its summer 2026 route roll-out with the announcement of new international routes and annualization of several southern services from Montreal, Quebec City and Toronto – with “further developments” to follow in the coming weeks.
For now, the airline has revealed that next summer it will introduce new flights between Quebec City and Marseille and Ottawa-London Gatwick, both of which are now open for booking.
“Our summer 2026 is already shaping up to be exceptional,” said Sebastian Ponce, Chief Revenue Officer at Transat. “We’re accelerating our growth in Quebec City, launching our first transatlantic route from Ottawa, and expanding our international connections. This is just the beginning of a season full of exciting new developments.”
They include:
New routes from Quebec City
From May 21 to Oct. 8, 2026, Air Transat will operate a weekly non-stop service between Quebec City and Marseille on Thursdays. The new, exclusive route to the south of France compliments the existing Quebec City-Paris route.
Additionally, the new Quebec City-Fort-de-France service, which is set to launch on Dec. 14, will be extended over the summer to include a weekly Monday flight, providing year-round access to Martinique.
New routes from Ottawa
For the first time, Air Transat will offer non-stop transatlantic flights from Ottawa to London-Gatwick, starting on May 15, 2026. This service will operate three times a week on Fridays, Sundays and Tuesdays. In addition, a new Ottawa-Montreal route will be available from May 5 to Oct. 23, 2026, fed by the growing network of Air Transat’s partner, Porter Airlines, which is consolidating Ottawa as a major hub in eastern Canada.
Year-round South routes from Montreal and Toronto
Beginning summer 2026, Air Transat will convert several popular seasonal routes to year-round:
- Montreal-Cartegena-Medellin, weekly on Thursdays
- Montreal-Guadeloupe (PTP), twice weekly, Tuesdays and Saturdays
- Montreal-San José, Costa Rica, twice weekly, Mondays and Thursdays
- Toronto-Cartagena-Medellin, weekly on Wednesdays
Notably, the Montreal-Cartagena (YUL-CTG) route will now operate year-round and be extended to Medellín (MDE). This service is based on the model of the future Toronto-Cartagena-Medellín route, which is set to launch on Nov. 2 and will also operate year-round. Together, the routes offer travellers the chance to enjoy both the beaches of the Caribbean coast as well cultural, urban Medellín.
Transat says the expansions are part of its strategy to develop its presence in Europe, Latin America, and the Caribbean, while providing travellers with greater flexibility and an even wider range of options.
