We feel your pain. In December 2016 we were informed they had cancelled our flight to Costa Rica in January and were left in the lurch because we had already paid for our Villa. Air Canada had a flight but it left at night so we technically lost an entire day of our precious vacation and ended up with an additional cost for a hotel room in San Jose because it was too late and dark to drive the 3 plus hours to the ocean to our Villa that was sitting empty for the night because we couldn't get to it safely. They also gave us a travel credit but it really didn't add up to what we had lost.

We are flying WestJet to St. Maarten in March on a TUESDAY but so far they haven't cancelled it. Thank you so much for the heads up - I'll be checking closely in the weeks to come.
