WestJet has announced today that they'll be commencing seasonal FLIGHTS TO DUBLIN in June 2014, in order to "test the market" for expanding service to Europe. The flights will depart St. Johns (Newfoundland), using their Next-Generation Boeing 737-700 aircraft (136 seats). Flight time will be 4H:15M and initial price will be Cdn$199 one-way. They will also be offering direct service (ie: one stop in St. John's but no change of planes) from Toronto, and connecting flights from other destinations in Canada.
I assume this will complement their existing code share arrangement with KLM for connections to Europe. According to some of the financial analysts I saw discussing this story, WestJet is still 3-5 years away from expanding service to Europe, as they'll have to purchase some long-haul aircraft first. In any case, it's an interesting development.
This new service will primarily benefit those in Toronto and the Maritimes, but it could also be a reasonable option for those in New York and the eastern U.S.
Cheers!
