Porter airline has it’s own airport which happens to be very conveniently located in Downtown Toronto unlike the main airport in Toronto (as it usually is, in most cities). But this airport is quite funny in that you need to take a 2 minute ferry ride across the river to get to the airport. You will spend more time waiting in the line then you will actually going across on the ferry.
The best part is the lounge in Toronto, which everyone has access to, has free WiFi and free drinks – soft drinks, tea, coffee and snacks. Definitely made getting abandoned at the airport a little more bearable. They offer fairly cheap flights from Toronto. Not many destinations, but since they fly to New York it’s still pretty convenient.
