I flew YQB>YTZ>EWR on Porter last summer. I enjoyed my flights on them, especially into and out of YTZ, but they aren't for everybody. They would not accept my TB number on the website or at check in. IIRC the only sort of agreement that they had with B6 was on BOS Flights.

EWR to YOW nonstop is on a Dash 8. It's a Turboprop with 2 x 2 seating. Legroom is decent but seats do not recline. I also wouldn't want to sit on those seats for more that 2 1/2 hours. Porter Reserve passengers get premium liquor and food. One note on Porter Classic, especially in the lower Classic tiers is that you are more likely to moved around for weight and balance purposes, even if you paid for seat selection.

On a trivia note, the Dash 8's don't have oxygen masks and as such, can't fly above 25k feet.
