The Flight took off 2hrs late because there was no pilot showing up when the flight was ready to board.. Though the cabin crew was present and had prepared the plane, the FO turned around after 15 min and went away. A crew to fly the plane finally arrived over an hour later and we were able to board 1h30 min later than planned time... until everything was loaded, we left 2h late from the gate. This was a small plane, so don't expect any Entertainment... Wi-Fi access on board would work, but took an awful amount of time to figure out and get it work (I'm an IT person). Flying as VIPorter customer, I was expecting at least some warm meal, but everything served was just cold.. except the coffee maybe. Even in so-called VIPorter seats, space is cramped and trays are so tiny, you can barely setup your food. Flight caught up during the coast-to-coast crossing and was able to recoup about 45 min from the delay.. still arrived very late in Vancouver and had to wait a long time to get our registered bags. Let's see how the return flight will be in a few days..

It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.

Due to a known technical error that Porter has not fixed in over a year, I was unable to check in the children on my reservation online and had to do it at the airport. Upon check in, there were no seats together, which was an issue as we had young children. The gate agent did manage to seat us together by moving other passengers, which was appreciated, but the other passengers were never informed, leading to confusion and delay upon boarding. The flight was over an hour late; no explanation or apology was ever issued. The bags on Porter take a long time to arrive--over half an hour at Hamilton on my inbound flight, and not much better on my return to Edmonton.

Much roomer than air Canada! Great flight for the price. No complaints

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

3.5 hr delay for a 1 hr work flight. No information as to why the delay until 20 mins before boarding.

Organization and the adjusted times but the snacks could be of a bigger portion

Smaller plane. Food and bar service for free is amazing. Drinks were in glass not plastic cups.

Poor landing as we overshot the runway and had to re land the plane. Lost both of my luggage not found as of yet. Had to pay extra money for my luggage in USD, now great my luggage is gone. Will not fly with Porter again.

This flight to St. Johns was really good. Boarding was a breeze. We left spot on time. Seats were actually pretty good. Recliner further than I expected. Three more flights to go we will see if this is the status quo for Porter.👍

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

l really enjoy very much the flight was very pleasant

I like flying first class, and United has a nice one

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

It was all good flight was on time, service was good I enjoyed a few movies and everything was smooth

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My seat was covered in vomit and I will be reaching out to Air Canada

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

3 hr delay at the gate while they were doing maintenance. Next time, do not board passengers while maintenance is being performed

Digital check in is very poor with air canada compaired to other airlines

Baggage delayed we had to catch our cruise without any clothes 😒

Air Canada Rouge is great. Toronto Airport is the usual nightmare

Good but need to be better with the flight times.

The staff was great and made the long trip easy peasy!

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.
