Air Transat has kicked off nonstop service to Rio de Janeiro out of both Toronto and Montreal, now standing as the sole carrier with a direct Montreal-Rio option. The airline schedules two weekly flights from Toronto and one from Montreal, with service running through early June. There's nothing accidental about the timing. Airlines in February are rolling out new point-to-point routes, aiming to capture winter travelers and skip connections that often tack on hours and hassle for leisure fliers.
