Airline reviews

A few improvements: 1. No signages at the airport that the porter airline was a codeshare and i could check-in at American counter. 2. Crew at the gate said they couldn't change my reward to Alaska - despite that being done previously 3. Despite there being many open seats, i was assigned a seat at the very back near lavatory, last row. Fortunately, the pilot wanted more people moved up so the flight attendants moved me up. It seemed very odd to have been stuck in last row with very few people nearby..

The flight booking code given by Kayak was not the correct one used by the airline. I had to call to get the correct one. It was never sent to me. Totally unacceptable!

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

As a first time flyer with Porter I was happy with the service and comfort of the airline.

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

The flight was fine see earlier note for the problem

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

Chaotic boarding, but mostly my issues are with Toronto airport

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

Porter is what Westjet used to be. Staff were great

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Liked nothing. As per previous segment it was delay delay delay.

Extremely uncomfortable sitting in a small space for 2 hours, especially for older people. Understood it was circumstantial.

Shout out to the check in counter staff in Richmond. So pleasant and helpful with ticketing and seat selection.

The ride was good but no food ot entertainment hence, it was just over an hour flight.

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

The flight ran out of hot meals for the back half of the plane and gave us tuna sandwiches. Not okay, these flights cost too much to short us the experience!

Our plane was so cramped that I couldn’t fit my bag below my feet and my knees were pressed against the seat in front of me. For a 45 minute flight, We sat on the runway for over an hour before returning to the gate to wait for another 2 hours. We arrived over 4 hours late, uncomfortable and tired.

The seats were not very comfortable. Looks like between saving money and reducing aircraft weight, the comfort factor was forgotten!!

I didn’t like anything. It was just okay. There weren’t any snacks and the seats were small. It was pretty uncomfortable. I think the flight attendants tried their best with what they had though.

The male crew member at the check-in counter was really really helpful, and we appreciate him a lot (I’m sorry we couldn't remember his name. He is an Asian Guy). Unfortunately, this trip is very disappointing. We did not know that we had to apply for ETA before boarding. I could catch the flight, but my friend could not, as the ETA was not approved until a few hours after the flight departure. We were deeply disappointed with the unclear instructions to prepare the document before boarding. This was a horrible experience for us, unable to get on the flight. We hope your company can do better in this issue.

Flight to Montreal departed on time. Flight was routine except for an unexplained delay in deboarding. Connecting flight to Halifax went well with good cabin crew service.

I left my Anker battery pack on my flight from IAD to YUL. I didn't notice until I had gotten to the international gate for my connecting flight. Not only did the gate representative go out of his way to contact United to find it, he also helped me get back throught security, so I could get to the United counter and pick it up. Stellar service from Air Canada!
