Air Transat is expanding its winter 2025-2026 network with the addition of Montreal and Guadalajara (GDL) in Mexico and extending service between Montreal and Madrid (MAD) in Spain to cover part of the winter season. Flights will be available for booking this week.
"The launch of these new routes reflects our commitment to offering a diversified network and effectively meeting currently underserved demand," says Sebastian Ponce, Chief Revenue Officer at Transat. "By targeting high-potential markets like Guadalajara and gradually making our European service available year-round, we are strengthening our position from Eastern Canada to the South and Europe, while maximizing our fleet’s operational efficiency. These are carefully curated routes that align with Air Transat's DNA."
Montreal – Guadalajara: Discover Mexico Differently
Starting December 13, 2025, travellers can fly non-stop from Montreal to Guadalajara twice weekly on Thursdays and Saturdays. In addition to serving the needs of Quebec's Mexican community, this service invites travellers to discover another side of Mexico.
Montreal – Madrid: Spain in Winter
Starting February 18, 2026, Air Transat will offer two flights per week between Montreal and Madrid on Wednesdays and Fridays, extending its summer route for the first time into the winter season. This expansion is part of Air Transat's strategy to reduce the seasonality of its transatlantic network by adding Madrid to its winter offerings for Spain, which already includes Malaga. Additionally, connections to several other key destinations in Spain are available through its interline partnership with Air Europa.
In addition, Transat’s joint venture with Porter Airlines allows Porter passengers from across Canada to connect with Air Transat’s network.
Details of Air Transat’s full winter 2025-2026 program will be announced soon.
