There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

The flight was fine see earlier note for the problem

Three hours on the tarmac with almost zero communication from the cockpit. Not when offered a water in the interim. In my 67 years of flying all over the world the worst experience ever. The plane was half empty, however had to pay for seats to sit next to my girlfriend. Extra to take a carry on. I would never fly Porter again even for free.

All good the seats a little tight and no I pad screen

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.

The whole experience from check in to deboarding was fantastic.

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

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

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

Airbus plane, nice and polite staff, entertainment even as it was a short flight.

Very nice and clean plane. Transit time between flights was tight though

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

So far so good but food and entertainment are not available for this flight

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

We tried to upgrade to economy premium but were told this was not possible as we had booked through United Airlines (and Air Canada was operating the flight). This seemed silly given there was ample space in economy premium. Additionally, we had to wait almost 1.5 hours upon arrival to taxi to the gate. Otherwise, the crew were very pleasant and passengers were friendly.

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

In spite of purchasing premium, I felt it was perhaps the most uncomfortable seat I have flown in. The base was either broken or poorly made and had no support. Even placing pillows and blankets on the seat (1D aisle) didn’t help. It made for a long and mostly sleepless six hour flight. Crew also were very loudly talking to each other through the night making it very hard to sleep. It was purchased for the price, so I get the risk, but was not impressed.

Worst check in and bag drop off experience. Staff were incredibly rude given that it’s the WestJet system that is faulty.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

We were happy with our experience. The price for tickets was much less than Delta and we actually took off and landed a little ahead of scheduled times.

Seat back entertainment monitors would be nice. We did enjoy the In-Flight WiFi.

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Absolutely terrible, from the customer service to boarding the plane. On the phone, there was some mishaps with getting in my correct date and they did not help me retrieve a refund or any assistance. I’m gonna be reporting to all my followers and family around the region of Los Angeles to New York.

Arrival at Comox from, London,ON 6 hours later... No bueano

Generally good. However. The flight left 30 mins behind schedule with no reason given.

Biggest problem for me is that I am Star Alliance Gold and they were not able to give me access to to Maple Lounge because of some computer glitch . It was management by information system. She could clearly see my status and still would not give me access because the computer woudl not let her. She should have override that be attentive to a customer and figure rhat out later

Great breakfast and coffee …..fastest bag service I have ever had in NOLA

Late departing. Late arriving. More worried about limiting bags on board. Free beer and wine a nice surprise.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

Orlando to Canada, despite being close and an international flight, the plane was not at all comfortable. It felt like the chair was being pushed forward, in addition to not having a TV and having to choose from a tiny glass of drink, for example, water or soda. I couldn't have both. When I asked the flight attendant for an extra glass of water, she looked at me with an ugly face. This is ridiculous. They don't want to give water to passengers. I will never fly with this airline again in my life.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

Great flights. 90 minute departure delay for maintenance issues, not a great start but, afer that very good. Didn't pay extra for seats and lucked into a window and an aisle seat. Price was excellent at the super low economy level.
