It was my first time flying with Porter and I went in with no expectations. Had a flight to Chicago on a Friday night at 8pm on a long weekend. I got to the airport around 6:30pm with little to no line for security (checked in prior with no checked bags).
The lounge was under construction during this time and for a Friday evening before the long weekend, it was packed. There weren't many seats available and many of the flights were delayed by an hour or more even though the weather was fine. Porter staff were diligent on announcing the status of each flight though so miscommunication was never an issue. The complimentary snack bar did run out of cups at times due to the amount of people waiting around but there were always staff around cleaning and refilling to the best of their abilities.
The flight itself wasn't too bad. For a short flight to Chicago from Toronto (around 1.5 hours), they served snacks and drinks. There was turbulence and because it was a small plane, the landing was bumpy but that was to be expected of a smaller plane. People who are not comfortable with plane rides would most likely not enjoy this experience.
Overall, though my flight was delayed and with the airport being busy, my first Porter experience wasn't entirely horrible. They made the best out of unfortunate circumstances. I would take their flights again due to the convenience of their services (complimentary snacks, in flight snacks, free shuttle, location).
