This airport makes flying out of Pearson seem exhausting.
The airport is great for many reasons:
1) It's right downtown! Take the FREE shuttle from union, take the bathurst streetcar or even take a cab (it will be under 20 bucks if you are near the dt core - under 10 if you are actually dt).
2) You don't have to get there 2 hours early - 30 mins is plenty of time. No running down mile long corridors trying to get to your gate either..
3) IF your flight isn't delayed, you will get out on time. No crazy tarmac line ups.
