WestJet and its unionized flight attendants have reached a deal to end their strike.

Flights were grounded over the weekend after roughly 4,400 flight attendants walked off the job on Sunday.

In a release early this morning, WestJet CEO Alexis von Hoensbroech said, “our teams are working hard to restore service and get our guests on their way to their destinations as quickly as possible.”

Further details on exactly when flights will resume have not yet been announced.
