We were lucky enough to arrive at the right time. The staff at YYZ did our complete check in and luggage tags for us. Even made sure we knew where we were to head next and how to get there. It truly was one of the best and easiest check inside. Thanks team.

Compagnie efficace et bons prix. Les sièges en classe club pourraient être plus confortables.

Lisbon, make sure to get food , coffee prior to going to boarding gates as there is no food being served after. Only vending machines. A lot of check points to get to the boarding gates. Not enough seating for passengers waiting to board. Crew was very courteous and kind.

Once we got through the long line at security, everything was very good from boarding to exiting the place. The flight crew was very friendly. What Air Transat could do much better is to put us through to TSA Pre-Check since my wife and I are Nexus members. We have never enjoyed this privilege with Air Transat, but, we always get this with Air Canada at the FLL airport. So, this is possible to do.

I think as another discount flyer they stepped up the bar. I think they should stay around for awhile

I really liked the club service, the temperature was ideal, the flight attendants were so warm and friendly and accommodating the bathroom was easy. Great flight.

The Air Transat representatives in Punta Cana need serious retraining on Customer Services. Lost luggage claims that goes helplessly unansweree, reps yelling at clients to go behind the red line as the check in line ballooned....

Would be nice if they could have a wifi service onboard and also if they had a food menu other then the one you have to pay !

Cons: "Baggage included ..the return to be certain, not be on standby when it was initially booked as a two way flight."
Pros: "Nothing"
Cons: "The city I went to was locked down due to covid. Neither the airline nor budget air helped me get a refund before the flight took off.. Still waiting to hear back..."

Check in was slow because of passenger ahead in Reserve line. Seats were somewhat uncomfortable.

First time with Porter. Amazing experience overall, will be my airline of choice in North America whenever possible. Liked the quality of food and how it was served but one suggestion- a hot meal on the longer flights, perhaps?

Delayed by 2.5 hours. This happened previously on my flight from YOW to YVR on Dec. 26.2023. This is a terrible airline. The reason was there was lack of ground crew. This is a known event. AVOID PORTER AIRLINES IF YOU CAN. There is a reason half the plane was empty.

The airline arrival at the downtown airport is a big plus.. Food and beverage was excellent. Their non weather related cancellation is horrible. Overall I gave the airline 7 over 10 Tips for people flying porter from Boston. The airline doesn’t have inflight entertainment No TV No WIFI. Bring your entertainment with you.

Wasn’t on the flight- again. Bad weather in Halifax and I was in an accident. What a poor experience to have to pay for all this flight and not be on it

I didn’t make my flight due to poor weather and I had an accident driving there. I tried to get my money back or even credit and nothing. I have an entire flight both to Florida and back that I paid for and no one will give me any money back. I know this isn’t just Porter and it’s 3rd party- however airlines should allow these companies to take money for things they don’t get. I’m so upset. Who can afford a full flight they never take?

Flight Ottawa to Toronto canceled and no crew was available to direct me on what to do. I opened a file and I wait to be compensated.

New jet. Lots of leg room. On time departure. Early arrival. Reasonable airfare. Excellent online experience.

I had checked in online the day before but was instructed to collect our boarding passes when we arrived. I am not completely comfortable using the automated Kiosks and always enjoy the nostalgia of speaking with someone when checking in for a flight. Upon doing so however, we were immediately asked,"did you check in online already?" To which I replied, "yes, but we were asked to retrieve our boarding passes upon arrival." She then said, "that's what those machines over there are for. We really encourage people to use those." That unfortunately sparked a series of shortness and overall poor behavior in my opinion from the woman who checked us in. I understand it was early in the morning but I am always excited to experience flying and that interaction has unfortunately left a bitter taste in my mouth to the point I will forever now hesitate to book with Porter again. Thank you for taking the time to read this. Cheers, JD

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

They lost my baggage on my connecting flight and we’re an hour late so I nearly missed it

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Staff are so nice and friendly, plane was very clean and plenty of leg room

Customs is always a challenge. The customs officials were real humans, which was nice-not robots programmed on angry 😊. If you’re in a hurry to get through you’ll be stressed out. Allow yourselves plenty of time and it will be a stress free experience.

As four hour wait with no explanation as to why the delay Very unacceptable

Excellent long haul experience really enjoyed using Dublin pre-immigration

Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.

The only issue I had on this long flight was that when the stewardess would come over the speaker, which was several times due to turbulence, it came into our earphones so loud as opposed to just being in a normal volume it made me jump and wake up. Others around me were also commenting on this issue.

We did not have a flight when we arrived at Dublin Airport. It took an hour of time for Aer Lingus to fix it. We booked our groups seats together but did not get to sit together after the mix up. The airline did nothing to apologize for the mistake. Wouldn't fly that airline again.

I'm Canadian. I have the unfortunate experience of pretty not having the choice to fly with them. THEY ARE TERRIBLE.

The process overall was pretty seamless, and the crew were very friendly (especially Michael). Considering we booked expecting Lufthansa and the flight was operated by United, it was still a very good service and journey overall. The in-flight entertainment was great, with lots of quality options. One slight negative was that I had selected a vegetarian meal prior to flying, but received a vegan one. I think there should be more dietary options as it meant I missed out on some food that I would have preferred (and it seemed like the standard meals and snacks had a vegetarian option anyway). There was also a group of people who were moving around a lot and being generally disruptive at the quietest part of the flight, when the lights were off and most people were sleeping. I would have appreciated staff stepping in to encourage them to be mindful of others). Towards the end of the flight (which was very early in the morning in both time zones), the lights suddenly came on and breakfast was served. In my opinion, this was too early, and everyone was rudely awoken from sleep. After breakfast was cleared away, the lights went off again for about 45 minutes, allowing people to sleep some more. Then the lights came on again for landing. It seems like if they had served breakfast later, the lights on-lights off-lights on shenanigans could have been avoided, and people could have slept longer (and staff could have rested longer too).

You only get a chocolate square and small bottle of water.!

to be bussed around the airport, then have to sit on the plane for an hour whilst the plane was deiced not once, but twice, then to have to wait for a tug driver is unacceptable. The Captain was very good at communicating.

Le personnel attentionné et trilingue, la tranquillité du vol. Aucun aspect négatif

Terrible. This airline will cancel flights at very short notice.

Overall good experience, just the delay of 2.5 hrs was a bummer.

Everything was fine except that the ground personnel in Toronto wasn't able to operate the jet bridge, so that everybody was stuck in the plane after landing for 40 min, so I missed my connection.

They have more than 4 hours delay, and broken all my bags

Very short flight so the limited space and lack of entertainment were no issue. Crew was friendly and the flight was very punctual. Baggage claim in Prague was lightning quick.

Terrible experience. Air canada is the worst and Kayak website is also not transparent.

My flight was great but my inbound flight from Toronto to Sault st Marir delayed more than 2 hours and we had to change the airoplan.

This was a fraudulent transaction. Kayak was at fault for accepting a stolen credit card. Kayak needs to change their verification process.

As is pretty much the norm with Air Canada now, we left late from the gate (45 minutes late). This is my 12th flight with AC in the last 12 months and 10 of those flights were either late or cancelled. AC essentially has a monopoly in Canada so they have carte blanche to charge exorbitant rates now and give poor service, with no repercussions.

I did not like the fact that our bags went missing

Airport staff super friendly. Even put us on an earlier flight because we arrived early.

A 2 hour delay because they couldn’t fit some oversized cargo in the small hold doors of an Embraer! Surely they know the sizes before attempting to load it?

It went well until they lost my baggage in Toronto. Bagging tracking stopped after my bag was unloaded in Toronto. My bag tag has been inactive since. I had over a 2 hour layover and there is no excuse for lost baggage with that time frame and only after one flight

-kayak did not give me advanced notice to my e-mail for my flight and I had major trouble finding the code to access Air Canada’s site because you did not provide it to me and incompetent Air Canada did not have any access based on my name alone. WTF -The flight was delayed twice. -They moved the boarding area -They said I would give free checked baggage because the plane was full and they charged me over $30 -They didn’t get my luggage on to the plane and left without it and I’m heading to a cruise ship. -I have lost one FULL day of my limited holiday and had to cancel scheduled events because my luggage did not get on the plane (even though the plane was delayed). -The “wheresmyluggage.com site is a total incompetent disaster that caused additional stress. -I will be sharing this experience

Plane was a Rouge vacation flyer for some reason. No legroom and entertainment. People were desperately looking for USB ports and such. And then there is this notorious and unsolved space problem where not all carry-on fits in the cabin….
