WestJet will be offering direct flights between London and Montreal starting on June 24 of this year.

The airline will provide the seasonal service through its regional carrier, Encore until Oct. 15.

"We continue to see robust use of our service between Montreal and Toronto and are aware that many of these guests travel to and from London," said Brian Znotins, WestJet's vice-president network planning and alliances in a media release Tuesday.

WestJet will compete with Air Canada for the route. Air Canada began daily year-round flights between the two cities last summer.

"Montreal is one of our largest markets, and with the addition of this non-stop flight our passengers can be in Montreal in a little over an hour," said says Michael Seabrook, President and CEO of the London International Airport in a media release Tuesday.

It's the third announcement of expanded service at the London International Airport since the beginning of the year.

Air Canada's Rouge and Swoop, the ultra low-cost carrier operated by WestJet, will also beginning operating flights to and from the airport.
