Ever since Toronto introduced the "Toronto Island Airport" I've been a fan. A city airport? What a great idea! First it was the convenience of it being in the heart of the city and the incredible Porter lounge, outfitted with MACs and a kitchen with Starbucks beverages, and all the snacks you could want.
Soon, the service and reliability of flying Porter became apparent and now, it's expanding! Billy Bishop Toronto City Airport will soon have a pedestrian tunnel between the mainland and the island. As it stands now, the ferry ride between the two may not make much logistic sense although it serves as a nice break for passengers to take in the gorgeous Toronto skyline.
