Hi there,
We flew Kelowna last January to Orlando. We ended up getting $99 round trip (plus taxes of course) from YYZ to MCO. However, that was about 2 weeks before departure. I had been looking a couple of months before and had found $139 round trip which was very cheap but hadn't booked. THe plane was fine. THey had a movie (or sitcom or some kind of tv thing)- and a meal. I booked our family's flight thru itravel2000.com. It reminded me of Air Transat- really cramped not much leg room. But for a 2 1/2 hour flight- the price can't be beat. I would pay the extra few dollars and call ahead and reserve seats near the front of the plane. On the way down we were in the back of the plane and it took at least 30 minutes (perhaps closeer to 45) to even get off the plane. Everything was moving so slow. But we were closer to the front on the way back and we were off much quicker.
Good luck and hope this helps. Just out of curiosity what are the flight prices now?
