Boarding pass counter did not open until 2 hrs before flight. We were there 3 hrs before as we like to be early ( eat, relax etc). Due to this the line up was large , thus never got through security till 15 min before boarding. Other than that, everything was great

Boarding pass counter did not open until 2 hrs before flight. We were there 3 hrs before as we like to be early ( eat, relax etc). Due to this the line up was large , thus never got through security till 15 min before boarding. Other than that, everything was great

We were very offended Reserva check in agent in Calgary. Erroneously profiled and reprimanded for using Reserve line . Hadn't even looked at tickets. We were in fact Reserve passengers

Even tho the flight was a bit delayed the team was apologetic. Everyone was friendly and efficient.

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

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.

I was not happy with AirfareAssist, the agency that kayak advised me would be handling my booking. I was advised by porter airlines that I had been overcharged for the Basic express , a option that I had asked airfare assist to help arrange after I realized that the basic fare I had chosen with porter did not include a carryon. At each checkin porter advised I had been overcharged for this . They advised that money would be refunded to my credit card, however, this is not likely to happen as it is not my name and credit card that appeared on the porter invoice, but that of another individual/agent. When airfare assist was arranging the basic express with porter on my behalf, they asked me to confirm that I agreed to pay $263 USD for this. I did agree, as I was advised this was needed to proceed. When I checked the invoice on the porter website and saw that it was not my name and credit card on the invoice, I was advised that this was how airfareassist processed the payment. The Porter invoice indicated a billed amount of $126USD I will not use Kayak or their designated AirfareAssist again

Everything was good except the fact you charge more for a carry on bag vs a check in bag and to top it off in US$ that was not impressive

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

Seemed like an old plane. Very noisy. The seat cushions were so old that the metal bracing of the seats were poking through. There was plenty of leg room though.

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

The WiFi was down the whole flight, a flight that had no on board of any kind

Crew were friendly and efficient. Love the hot towel service!

3 delays on my flight. The cabin was cold and noisy.

The Airbus ride was noticeably different in a positive sense. Beats the 737 in leg room, which is important for my height.

I supposed to have a wheel chair waiting to take me to the luggage carousel. Didn’t happen so I had to walk up the walkway with my cane. I lost my balance and broke my little toe on my right foot, which means that I’m hobbling around with a very painful left leg and a very painful toe on my right foot. It was a nightmare.

It was a very pleasant trip from A to Z.

Every leg of my trip with Air Canada was delayed Never offered as much as a small bag of pretzels on. 3 hour trip Printing boarding passes at the airport when told to bring printed boarding passes with you Unable to load passes into my apple wallet- so very easy with other airlines

on a 5 hour flight from toronto to san fran, no crackers or cookies, nothing. i was surprised. I liked the wider seats coming home. I hated being put in section 5 and don't know how you figure that stuff out. I bought tickets mid summer. was it because I was economy? I am 75 and had to turn over my carry on both times. It is hard for people of all sizes and disabilities to fit into spaces. I liked the staff, and that we got through the fog. You are stuck with planes and economics in order to function, so whoever is reading this, it's nothing much you can do, except, perhaps, offer a tiny snack free on 4 + hour trips.

Everything went smoothly and according to the itinerary. No delays.
