The agent at check in was very cordial and gave me seat 4a with nobody beside me as I asked if possible

Seats not as comfortable but understand as it was a smaller plane/ short flight. All in all, I’ve never had any issues with Porter. Great company to fly with

Look, I understand that Kayak doesn't know I cancelled my flight on Porter. So I didn't actually fly yesterday. My main disappointment is with Porter ticket fare policies, and maybe you can pass this on to them: At my employer's request, I had booked a full fare ticket with no change fees since my trip to Toronto would likely be extended. Indeed, when I went to change my flight home to a later date, I was told the Fare Difference would cost an additional $550. So much for no change fees lol! While I had the agent on the line, I hopped over to Kayak, searched for new flights on the date in question, and saw a one-way ticket that got me home for only $355. So I got reimbursed about $450for the unused half of my roundtrip and bought a new ticket for $355. What good is a full fare / no change fee ticket if they screw you with "fare difference" BS. I'm still flying home on Porter Airlines but they just lost a hundred bucks with their stupid shenanigans.

I flew with Porter yesterday and overall had a positive experience. The flight was delayed, but the airline did a good job keeping passengers informed with frequent updates throughout the process. My biggest challenge was actually in Terminal 3, where the speaker system wasn’t very clear. It was often difficult to hear the announcements, which made it harder to follow updates at the gate. On board, the experience improved significantly. The aircraft felt very new and well maintained, and the seats were surprisingly comfortable for a short-haul flight. One of the flight attendants seemed a little disengaged, but the other was excellent—friendly, professional, and a pleasure to interact with. Despite the delay, the comfortable aircraft, clear communication from Porter, and positive onboard service made for a good overall experience.

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

The staff was amazing. Best service I’ve had on an aircraft in a long time. Was not particularly happy with the food. Flight was at 10:50 and left home too early for breakfast and wasn’t able to purchase food at airport and felt for sure I could get some breakfast to buy on airplane. Nope as food was served around 11:30 and only one choice left (I was at 22C) so ordered the chicken dish thinking I’m getting a hot meal but cold chicken with rice and carrots etc. I was looking forward to a croissant sandwich and a hot cup of tea. The FA was kind to explain they were serving dinner at that time. She was lovely Other than the disappointment with the food the staff was amazing. On my return flight I will make sure to eat and take some food with me so I’m not hungry or disappointed. This was my second time ever flying Porter and will consider checking them when I next come to visit my daughter. Have to say it again best crew I’ve ever experienced on a flight and I travel quite a bit. Thanks.

I didn’t receive any help when they messed up and wasn’t honest and the supervisor did absolutely nothing to help me so I had to buy another ticket at $537

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

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..

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.

The pricing was split into an ultra basic fare with a comfort seat upgrade. This is misleading. Never were we shown an ultra basic fare. What this did because the fare category was ultra basic we could not bid on an upgrade first class seat. All e mails from WestJet were for ultra basic category with my wife and I upset as we could not confirm this with anyone from your firm.The check in counter were not going to allow our carry on but after some checking saw we had ultra basic and a comfort seat upgrade. They could not figure out how this was done. Now we have to go through this again at the gate in Mexico. Unless I missed it - please let customers know the billing in future. Respectfully. Gary & Nancy Moughtin

As someone who never flies WestJet unless there is no other viable option I have to give this crew credit where credit is due. Extremely well done everyone.

Everything was great until we had to get our bags. The bags came out in several different batches over 90 minutes after we landed maybe more we got our bags. So much for the old West Jet where they promised bags in 20 minutes. I Next time I will pack lighter and go with a carry-on.

Great seats, super comfortable, but no in flight entertainment which was a let down

Food good . No entertainment. Need to use wifi to access your own apps. Eg Amazon Prime, YouTube. They don't tell you unless you ask.

The flight attendants were great, but not much room while sitting and it would be nice to get free movies.

I like the leg room in the exit isle..easier to get past people and I did t have to pay extra! Westjet changed my return flight time to a night flight 2 weeks before I left and left me hanging with NO HELP to resolve all the frustration they caused since I booked thru BudgetAir. They receive the lowest of star ratings I can give (if there was negative stars I’d be using those) for customer support and an overall bad score for the rest of the experience! So sad cause they used to good :)

Better boarding process, but not the fault of the airline… people are dumb.

It was a swoop flight at a west jetfare… the plane was literally a swoop branded plane.. I pay extra to NOT fly the budget carriers like swoop and flair so needless to say I was annoyed when both my outgoing and return flight were on swoop planes.

Both flights we boarded and had to wait 1 hr/45 m respectively before leaving the gate. This was over and above normal times. Seats and space not comfortable.

Mutiple delays and changes of gate resulting in arrival 5 hours after intended.

It was great other than the plane was really small

The crew members were great. The flight was awesome. But I had trouble getting to any of the movies. I tried over and over. The free wifi though is a bonus which I appreciated. Re comfort I am not telling you anything you don’t know. There is nothing comfortable about air travel any longer. As someone with a back issue I am usually squirming about two hours into any flight. But safety matters most of all to me and I do feel safe with air Canada.

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!

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

No possibility to get a refund or rebooking because of illness.

My flight cancelled 3 time and rebooked. It was unexpected for me. Otherwise everything is perfect.

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
