Air Transat's Montreal–Reykjavik (YUL–KEF) service launched on June 16, 2026, marking the carrier's first-ever entry into Iceland. The seasonal route runs through September 27, 2026 on the Airbus A321LR. Scheduling data indicates weekly operations, though Simple Flying reported the service as three times weekly; readers should verify current schedules directly.
Keflavik International Airport (KEF) already has Montreal service via Air Canada, making Air Transat's entry a direct competitive addition rather than an entirely new market. Air Service One confirmed Air Transat as one of two new carriers at KEF this summer alongside Alaska Airlines (Seattle). The Guide to Iceland also updated its airport guide to note Air Transat from Montreal as a new 2026 arrival.
Aviation Week's June 2026 new-route preview noted that the KEF route "restores competition on a market currently served only by Air Canada." Iceland remains one of the North Atlantic's fastest-growing tourism destinations, with visitor demand driven by northern lights tourism, geothermal experiences, and a growing summer festival scene. The A321LR's range makes the roughly 4,400 km Montreal–Reykjavik sector feasible without a technical stop.
