I am also writing this review from the Porter lounge and am liking my experience so far. For convenience and amenities, you really can't beat it.
My 330pm flight to Newark is delayed, but they bumped me up to the 130pm flight that is supposed to depart at 335pm. Overall, not so bad, but I suspect more delays. It's the nature of the game for NYC area airports. I don't think delays can really be blamed on the airline, since I assume it is mostly weather or traffic issues.
The only part of the experience I didn't like was the bumpy ass ferry ride. Worst 60 seconds of my life. However, I am a two minute walk (literally) to the airport, so I can't really complain. It beats driving my fat ass to Buffalo and catching a flight there.
As they add more destinations, this airline is going to blow up! Let's hope they don't lose the amenities going forward. [rating subject to change as I experience Porter more often].
