The new aircraft touched down in Toronto on Tuesday (1 October) following “extensive trials”.

It comes after BA tested the A350 in Dubai last month.

After Toronto, BA will debut the A350 on flights to Tel Aviv and Bangalore later this year.

BA took delivery of the A350 earlier this year, and has carried out more than 15,000-miles testing between Heathrow and Madrid, including 40 take-offs and landings, to allow crew to acclimatise.

It has also simulated long-haul flights on the ground.

The A350 features Club Suite, BA’s latest business class seat, with direct aisle access and flat-bed seats in a 1-2-1 configuration.

Features include 40% additional storage, 18.5-inch screens and gate-to-gate HD programming, and PC/USB power.

Gerard McEvoy, BA vice-president sales, North America, said: “We’re thrilled to be launching our new A350 from Toronto, a city we’ve flown to and from for nearly 60 years.

"The A350 and our new Club Suite business class seat deliver new levels of sophistication, comfort and privacy, and we’re proud to share this with our Canadian customers.”
