MONTREAL — Air Canada is undertaking a major expansion of international services to Europe from Toronto, Montreal, Vancouver and Calgary.

The airline announced highlights of its Summer 2014 Europe schedule, which includes the introduction of year-round nonstop service from Toronto to Milan with up to five weekly flights, offering the only nonstop service between Canada and Milan.

Flights to this key Italian business destination will feature Air Canada’s award-winning Executive First cabin of service.

In addition, Air Canada will increase its year-round Toronto-Istanbul nonstop service to daily flights from three times weekly. The airline will expand the availability of its new international Premium Economy cabin with its introduction on Vancouver-London Heathrow flights year-round, as well as Montreal-London Heathrow flights during the peak summer travel season.

Air Canada will also deploy larger aircraft from its international widebody fleet on flights from Calgary to London Heathrow and Frankfurt, as well as from Montreal to Brussels and Geneva in order to meet travel and cargo demand during the peak summer season.

As part of the Summer 2014 schedule, Air Canada’s leisure carrier subsidiary, Air Canada rouge, will launch seasonal nonstop flights between Toronto-Lisbon, Toronto-Manchester, Montreal-Barcelona and Montreal-Nice. The new routes supplement the leisure carrier’s other popular vacation destinations, including previously announced Toronto-Dublin year-round service, as well as holiday and cruise package options offered in conjunction with Air Canada Vacations.

Seats on these new Air Canada and Air Canada rouge flights are now available for purchase through travel agents.
