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.

Other than wifi no on board entertainment. Will use them again, roomier seats than other airlines and snacks and beverages, better than average

I like it, but the food isn't good. They need to offer more simple things. This bowls that have so many things your don't know what your are eating. The milenials like it, no the rest. And last but not least, they allowed somebody have a huge dog, vey agressive and fidgety in the flight. That's horrible. No animals should be allowed inside the airplane, what about allergies, etc

Smaller plane. Food and bar service for free is amazing. Drinks were in glass not plastic cups.

The flight was half empty yet they charged me $50 for a basic carry on! I saw how passengers of different colors were treated differently.

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.

This flight to St. Johns was really good. Boarding was a breeze. We left spot on time. Seats were actually pretty good. Recliner further than I expected. Three more flights to go we will see if this is the status quo for Porter.👍

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

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

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Getting to the flight was arduous and lengthy. The flight itself was good but the food option wasn’t a good selection. I need to do a Kosher option on my return. Flight crew were nice

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

Very nice flight love the small aircraft. We had a wonderful flight attendant. Nice to see someone that really enjoys her job. Don't have her name but had a southern accent.

Seats in waiting area and on plane hard as rock. Fast internet on the flight was great! Crew was kind.

Not the fault of United—weather, reroute around weather, time sitting on tarmac, arrived couple hours late, too late for train into city necessitating a much pricier cab but weather…can’t be helped.

Flight was good but there are way to many announcements for credit cards etc.

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.

From the first moment you interact with United Airlines, you can expect nothing less but extreme frustration. The baggage handler at the bag drop seems completely unbothered by the presence of customers waiting in line. No help was extended to load the baggage whatsoever. And if any of your bags is overweight by 0.01 pound they will make you re-distribute everything in your suitcase just to play power trip. When it was time to board no help was extended to customers to locate their seats. Moreover. It was a chaotic mess at the gate when it was unclear who should board first and everyone just bunched up, trying to get on the plane. I am sure the crew was doing their best to perform their jobs while being paid their wages however it shouldn’t be that hard to smile once or twice when you’re in the business if serving customers. It is a shame for the United States of America to have a flagship carrier of such low caliber. Our flight was also delayed by about an hour and a half due to further delays prior to our inbound flight. Being someone who has travelled for both business and leisure in Asia, Europe, and South America I have never experienced such poor quality of service.

Flight delayed missed connecting flight crew not very helpful very frustrating customer service

The personal item sizer cannot take a standard backpack, and the cabin luggage sizer cannot take a standard carry-on. Designed for people from the island of Lilliput!!. and also compels people to pay additional fees to check their bags. Making money by ticking off the passengers is a very short-sighted business strategy, especially since they have a choice of carriers

The plug in to charge our phones are all loose my block would not stay in!!

My flight was cancelled due to weather but Westjet got me on a new flight in a timely and efficient manor.

The only thing I can't give good or really good is the fact that we didn't have food ,just a packet of pretzels or cookies which is normal,and ofcourse there isn't any entertainment. I've always flowen WestJet ..I really like the airlines..this plane was smaller one ,pretty tight seating.

Again, flight was late. It’s expected of this airline now i guess.

I rated westjet poor on food for not accepting debit to make in flight purchases. This is dumb.

Our flight was delayed almost 3.5 hours (some of the issue seemed to be weather-related, yes) but NOTHING was offered as an conciliatory gesture for this delay. No food offering or any additional drink offering. There is no entertainment is available on any screen behind the seats. The airlines are so quick to penalize customers for slightest requests for comfort- seat changes, complicated baggage allowances, seating zones which are utterly dehumanizing (ZONE 9? after Zone 4- why? This is so clearly meant to be a message to those that do not have 'loyalty' to this airline to make a distinguishing line in the sand. There is such a lack of humanity in the way people are corralled in and spoken to. So, I don't think airlines should be all that surprised when those some dehumanizing corporate treatment is returned to them when asked. The flight on the way into Calgary was scheduled to arrived at 9:25 and we arrived at 12:45 AM. It is not okay. I would think TWICE and possibly once more before booking with them again. Their overhead bins are small and limited so they bully you into either paying for a $90 checked bag or gate check a lot of people's bags. Often on their website there is no carry-on bag allowance. Beware!

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

They were on time and everything went as expected. The only thing that could be better was they didn't wait for us to get through customs to pick up our luggage off the carousel. An employee picked it up and was shoving it together with others onto a cart. Later we found one of our luggage was slightly bent.

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

Very nice staff members are very nice and friendly helpful

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

Just the stress of possible cancellations on flights from Air Canada, but all went as planned and everything was perfect! Thank you

It was good to receive a card for my birthday

It got cancelled and they haven't given me a flight back yet!!

It would have been better if it wasn’t cancelled

Awful. As we were boarding we were told the flight was cancelled. Then had to stand in a queue for 3 hours to talk to someone at the kiosk of Air Canada. They were not helpful at all. No empathy. My issue is not with them striking but the total disregard for the chaos and distress late notice caused. No thought on the impact this has caused.

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.

I had a good experience. I liked being informed about the status of my luggage
