As bus routes go, this has ease of use written all over it. For one thing it is pretty much door to door service taking you from the Kipling station non-stop to the airport and vice versa. The lack of stops between means that the time flies, and before you know it you are airport bound.
As a bonus people are used to travellers on this route so bring the huge bags and cop a seat.
Bottom line...it's the little TTC bus that could and did!
