Not exactly the nicest airport in North America or even Canada, but looks like the improvements are coming along. They're currently building a new wing and hopefully that'll make the Calgary airport seem a bit more international.
Right now the domestic terminal is decent with a few different dining options. The positive is definitely access to the Maple Leaf Lounge. The international departure side still needs a bit of work. All in all, an ok airport but definitely not one I'd like to stay at for more than an hour. Luckily we don't layover here.
