We are going at the end of August from Regina and I've been watching them as well. Delta seems to have the cheapest flights so far but they never seem to give your much more then an hour to get to you next flight and of course you are going through customs. What kind of time did you get between your flights? I'll keep watching for a bit more but I think I might end up paying more to fly United so I have a few hours between flights and enough time to get through customs.
