Served by the latest addition to its feet, the B737-8 MAX, the daily, non-stop service operates until October 26, 2018.
"WestJet's addition of this direct route represents another link to the UK and connections throughout Europe, important markets for Nova Scotia," said Geoff MacLellan, Minister of Business and Tourism for Nova Scotia.
"This route will help further connect our people, cultures and businesses, making it even easier for UK tourists to visit our province. On behalf of the provincial government, I want to thank WestJet for its confidence in our region and ongoing investments that are helping to build our Atlantic Gateway."
While Halifax International Airport Authority's president and CEO, Joyce Carter (pictured above, second from the left), remarked: "WestJet continues to demonstrate their commitment to Halifax Stanfield, our community and our future as we expand into an airport where travellers can conveniently connect to and from Europe and beyond.
"We thank WestJet for their leadership in developing new links to European markets from our gateway, and the travelling public for supporting new services."
Talking about the Boeing MAX, WestJet's interim executive vice-president, commercial, Tom Coyle, noted: "WestJet continues to demonstrate its commitment to innovation using its fleet of fuel-efficient, guest-friendly Boeing MAX aircraft for transatlantic service.
"This service also demonstrates our commitment to support efforts on the part of Nova Scotia and Atlantic Canada to enhance trade and tourism, and grow the economies of both Canada and the United Kingdom."
On May 31, WestJet will launch its inaugural flight between Halifax and Paris on its Boeing 737-8 MAX aircraft.
The flight will mark the first time WestJet will land on the European mainland.
