WJ announced an updated impact of the MAX grounding through to July 3rd:https://blog.westjet.com/guest-advis...ax-groundings/

The slightly eye popping bit is:

Flights between Halifax and Paris have been suspended from June 3 through August 2, 2019. We are in the process of contacting affected guests who will be rebooked through either Calgary, non-stop on our Dreamliner to Paris, or with one of our partner airlines through Toronto, Montreal or New York.

Can't imagine anyone in YHZ wanting to fly 8 hrs in the wrong direction just to get the Dreamliner to CDG!
