The St. John 's International Airport Authority said the launch in 2013 was the "most successful launch of a new route in WestJet's history."
"We are very disappointed with this decision, but with continue to work with WestJet to grow their services from our airport," a spokesperson said in the airport's release.
The route to Ireland has not been performing to the airline's expectations since its launch in 2013, the spokesperson said, and will therefore be discontinued.
WestJet is in the process of contacting anyone who booked a flight on the St. John's-Dublin route to inform them of the itinerary change through the Halifax route.
This year, the Calgary-based airline has announced a number of route changes, axing a twice-daily flight from Deer Lake to Halifax, for example.

The St. John’s International Airport Authority says it is disappointed that WestJet has decided to eliminate its seasonal daily non-stop direct service between St. John’s and Dublin, Ireland.
The service was launched in 2013 – the most successful launch of a new route in WestJet’s history according to the airport.
The airport authority says it is disappointed with the new and will continue to work with the airline to expand their services from the airport.
WestJet says it did not take the decision lightly, but says the route was not “performing to expectation” and as a result they decided to discontinue the service.
The airline says it remains committed to growing aviation in the province and has recently added non-stop service between St. John’s and Fort Launderdale in the spring of 2019.
WestJet is currently contacting all those who have booked flights on the St. John’s-Dublin route to let them know of the itinerary change.
