Not being familiar with Porter I assumed that the reasons its prices were lower than other airlines was because it operated on the same principles as Frontier and Spirit: "Oh I'm sorry, you require oxygen? That will be $50 please."
After reading glowing review after glowing review I was assuaged and am very glad I decided to fly with Porter.
I expected the free snack but the complimentary wine/beer was a total surprise. My flight connected in Toronto and the lounge was great: plenty of space, free coffee/tea/water/sodas, free cookies, free wifi. The staff was very professional and friendly enough.
Not to say that everything is perfect. They do fly on turboprops and the Bombardier Q400 I flew in, while comfortable, could have used a little more elbow room. But that's quibbling, and would not prevent me from flying with my new favorite airline again.
