And actually, for those who have experience in this area, what would your thoughts be on 2240 AM for a round trip ticket (Ottawa to Orlando), low season (Nov 24-29), direct one way (no direct flights offered by AC or WJ on my preferred dates), plus $150 for taxes and fees? I am trying to do the math and right now I can get the 2 tickets for $800, so am torn on if 4480 AM plus $300 is really that good a savings...
If you're saving $500 for 4480 AM, that puts the "value" of your miles at just over 11 cents/mile. Cash miles are worth about 10.5 cents/mile, so you're a little ahead of that mark. You could probably do better (eg. Universal tickets are listed on Undercover Tourist at US $263, and available for 2425AM - a value of just under 11 cents US, or around 13.5 Canadian cents/mile at current exchange), but you could certainly do worse too. So I think it just depends on whether you'd rather spend the cash now and keep the miles for a better "deal", or save your money now. IMO neither would be a "bad" choice.
