I have been here so many times in my life, I was pretty mellow. Little did I realize the greatness of this airport... there are only two feelings you should have.
1. You have been away from home and flying back into Canada (im home feeling). You are greeted by the huge Canada sign before heading into customs... gives you this great im am home rush. Followed up by anxiety picking up baggage if you need to then the international exit gate which splits left and right. You can see all the Canadian families waiting anticipating someone while you look for yours (the second im home rush to the i dont care i wish i was still travelling).
2. You are the anticipating family or friend member (anxious when are you going to come out feeling).
Now the best part, Pearson Airport now has FREE WIFI. What every airport in the world should offer!
