British Airways will start flying two new routes in spring next year, to Toronto and Las Vegas.
Direct flights from Gatwick to Las Vegas will begin on 27 March and Toronto from 1 May. Both flights will run three times a week.
The new flight to Toronto will be British Airways’ first flight to Canada from Gatwick.
The Las Vegas route, which already operates from Heathrow, is in such high demand that the airline will now offer a service from the two biggest London airports to give customers access to a greater number of seats and a choice of departure airports.
Sean Doyle, British Airways’ director of networks and alliances, said: "Gatwick has always offered a great range of long-haul destinations, but adding Toronto and Las Vegas to the summer schedule will take the number of transatlantic routes to 21, making Canada, the US and the Caribbean more accessible than ever before."
