The airport has a very nice feature - express moving lanes that have creative use of expansions and more. I like this for the superlong walks shortened by a significant amount (roughly 2x the speed of walking on the regular moving walkways).
Overall, the airport is relatively clean and staff friendly, though I would appreciate better and more dining options in the international departure area. And more power outlets. Large duty-free shop in the Terminal 1 departure area. Signs are mostly clear, and bathrooms are clean (as of a morning flight, though).
Internet is free, if slow, though, courtesy of Rogers. One bright side of having to wait here.
