I just booked our flights from Ottawa to Orlando this morning. I've been monitoring the fees for the past 6 months and when I noticed $149 each way this morning I opted to book! Our connection is via Montreal...
I know you can easily reduce this price with another non-canadian carrier or flying out of another airport however for the convenience of having 2 small children and minimizing the travel time to and from an alternate airport this is by far a great deal.
Hopefully this helps someone else have a magical day!
