If you want to travel to Toronto or Montreal, porter is DEFINIETLY the way to go! Just make sure to sign up for their newsletters, and you will get e-nmails about when they have sales. Don't feel rushed to grab onto their sales, since every time it's their "biggest sale of the year", which happens every few weeks. You get free wine and a snack, and the porter lounge in Toronto is really nice. Only annoying thing is that all flights have a layover in Toronto, but it's usually a quick layover, and you get free nuts, cookies, soda and espresso!
