Air Canada claims to be the first North American airline to configure aircraft with lie-flat seats for premium cabin passengers on selected long-haul flights within the US and Canada.

Signature Service will be available on international flights and on selected transcontinental services within North America from June 1.

These include overnight daily flights from Vancouver, Los Angeles and San Francisco to Toronto.

The upgraded service will be available on selected trans-border and domestic Canadian transcontinental flights operated by Boeing 787 Dreamliner, Boeing 777, Boeing 767 and Airbus A330 aircraft.

These cover routes between Toronto and the cities of Los Angeles, San Francisco, Vancouver, and between Vancouver and New York-Newark and Montreal.

Passengers will also receive access to airport concierge services, speedy check-in and security clearance, priority baggage handling and preferential boarding.

The airline did not disclose the cost of the service but described it as reflecting ongoing refinements to its premium travel service on longer flights.

Air Canada passenger airlines president Benjamin Smith said: “Customers travelling Air Canada Signature Class on international itineraries and, beginning in June, on select transcontinental flights within North America, will receive seamless Air Canada Signature Service.

“They will enjoy added amenities throughout their journey, from curbside-to-curbside and at all points in between.”
