Further to West Jet (WJ) and cancellations, another good point would be to check the mobile app often. WJ seems to like to send notifications of an itinerary change when one flight lands 6 minutes later than on the itinerary but when it comes to cancelled flights they don't put that on the web, or even notify you via email. March the 21st when the world changed forever, we never got an email saying our flight out of MoBay was cancelled and in fact WJ was still selling fares back to Canada for March and April. Wife and I changed out April departure to March 22nd just because our esteemed leader JT told us to come home. The 22nd flight was listed and they took our money but March 21st our neighbour downstairs said all flights after midnight on the 21st were cancelled. I went back on the website and WJ was still selling tickets for March/April but when we checked the mobile app it said all flights were cancelled. This left us scrambling to get off the island. At 9AM we got a flight to Toronto for 1 PM same day.
