I do agree that this is a good price for a direct flight from YOW but just to mention alternatives for the same dates (May 12-19):
FrontierAir : SYR-MCO : $142.99USD = $188CAD with Frontier Discount Den ($49.99USD per year but allows you to buy mulitple tickets (i.e. family of 4 only needs one membership)
AllegiantAir : SYR-SFB : $187.50USD = $247CAD.
This is just the basic fare, no seat selection (which I never get), no check-in or carry-on luggage (which I believe all 3 charge for so might not be a significant difference). You also have to consider parking (e.g. I can Uber from my house to YOW for about $50-60 return. Obviously, that's not an option for SYR), snack on the road, etc and you have to consider the gas to get to / from SYR (I'm sure it's at least $75 of gas for us). Also, obviously SYR is considerably farther than YOW for probably anyone reading this thread so that's a consideration but depending on the number of travellers, the savings are considerable. (e.g. we're a family of 4 so we'd basically save $1000 - personally, I'll drive and fly out of Syracuse to save $1000. For anyone considering it, I believe you can get a "Stay, park and flly" hotel in Syracuse for about $100-$125USD so that's something to consider since you'd save the airport parking fee). You also have to consider the value of your time - the drive to SYR does take a good 3 hours so that's 6 hours total to consider.
