Over the past few years, one strategy that's gained traction is choosing to fly out of an alternative airport (namely John C. Munro Hamilton International Airport) over Toronto Pearson Airport. For example, Hamilton to Winnipeg during the Aug. 10-17 window is $445 round-trip, while flying direct from Toronto will cost you $410. For the same dates, Hamilton to Montreal is $317, compared to $268 from Toronto. A round-trip flight with Porter during the same August window is $365 from Hamilton versus $402 from Toronto. The same story applies to Paris ($707 from Toronto, $1,200 from Hamilton), Dublin ($514 from Toronto, $793 from Hamilton), and Rome ($780 from Toronto, $948 from Hamilton).
