How far can a loonie take you on Sundays? Perhaps all the way across the country. That's insanely good mileage for the buck.
Every Sunday on jetsgo.net, after midnight, hundreds of seats for $1 are up for booking. You might want to set your alarm clock, because they take off like crazy. Then again, if the idea of waking up in the middle of the night drives you mad, no need to go nuts… until later in the day, when you'll still find thousands more seats at frantically frenzied fares.</font>
Now, I know
some of the taxes are a percentage calculated on the fare, but other charges, like the NAV/INS fee (whatever THAT is) is $37 per leg! So your $1 fare will end up setting you back probably substantially more than $100 (maybe even $150).
Frankly (and I DO hate to say this since I really do love Canada/Toronto), South Beach is a better deal.
