I travel often 8 month of the year I fly some where, and my port of exit and entry is of course my world class airport right here in my hometown.
I enjoy this airport more than any other, not just because I live here and I am at the airport quite frequently. But also because the services and shops at fantastic! Terminal 1 is my favorite of the 2 terminals, The Maple Leaf lounge is here and I always go and relax there - better than the American carrier's lounges or the privately owned ones. The food court is great, and there are lots of open spaces.
From Pearson you can take a direct flight to so many other major cities around the globe! That sound so exiting to me! 90% of my travels are for work but I can always take a direct flight to anywhere I am going. This is why Pearson is the hub that it is!
