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..

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!

It was okay. Had a thing with the front desk, she had me repack my suitcases to have them be under the weight restrictions, but then the other one was overweight, she argued with me about it when there were tons of people in line. Wasn’t great.

Due to a known technical error that Porter has not fixed in over a year, I was unable to check in the children on my reservation online and had to do it at the airport. Upon check in, there were no seats together, which was an issue as we had young children. The gate agent did manage to seat us together by moving other passengers, which was appreciated, but the other passengers were never informed, leading to confusion and delay upon boarding. The flight was over an hour late; no explanation or apology was ever issued. The bags on Porter take a long time to arrive--over half an hour at Hamilton on my inbound flight, and not much better on my return to Edmonton.

On my e-boarding pass it shows free wifi, yet the plane I was on didn’t have wifi. Please remove false advertising from your website and boarding passes

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

Organization and the adjusted times but the snacks could be of a bigger portion

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

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.👍

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Improve boarding- the zone assignment and boarding is always a mess- there is not clear instructions of what is going on at the gate. As a meme bet there is no more selection of a good seats when booking. Only offers middle seats to choose or pay extra. There is not more benefit with Amex no benefits at all.

alike schedule and times it’s very good for me, I will stay wad delta for ever

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

2+hrs delay without any reason provided and a cramped flight

We waited an hour on the runway to get a gate in Orlando

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight attendants had a little attitude. Food tastes no good.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

Very poor. The flight was delayed from Toronto because some forget to do there job . I got to my connecting gate in San Francisco 10 minutes before the departure.but this didn’t let me board even though the flight was still there for an other 30 minutes. The the gentleman at the unite airline desk told me that they usually wait for passengers but air Canada called and told them not to we I been rerouted to Manila instead of Hong Kong . In San Francisco they mad me check in my carryon bag . I was told the it will directly go yo ho chi minn cuyt but I was told that by the Vietnams airline desk that’s not there I’m 10 hours behind my scheduled flight and looks like I I’m going without baggage. I don’t have a chance of catching ..

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

l really enjoy very much the flight was very pleasant

I like flying first class, and United has a nice one

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

Experience was good, the wifi hook up is somewhat tough

Great flight, great landing, nice staff. Our seats were a little cramped.

I will not be flying with westjet again. I was uncomfortable in my seat. The position made my back hurt so bad. My wife was able to fit the seatbelt around her with out an extension but was unable to put the tray table down or fit in the seat for that matter. Our bag was smashed and I spent two hours trying to fill out the application for a damaged bag before I gave up. The 80 photos I took would not work and nothing telling me the format to upload them as.. I made the mistake of unpacking the bag before taking photos so no claim for me. Next trip to Canada I will have to use air Canada.

Overall good experience. The wait for baggage at our destination was quite long, but other than that everything was good as expected

Airplane is too small. Crew, especially the flight attendant who looked after our area, was not at all friendly and a touch authoratative. She may have been the most gruff flight attendant i've come across in 40 years of business travel

I selected "carry-on" for a round trip on Kayak, but my return flight on WestJet did not include a carry-on and they would not allow me to add one. My only option was to add a "checked bag" which I had to wait for on the luggage carousel after landing. Not a good experience.

I was seated near a "stinky" person. That's not the fault of Westjet🙁😶‍🌫️

Do not fly on WestJet if you have a connection. It failed to integrate with my connecting Delta flight and I almost missed it.

There was a man who was very rude at boarding. On the other hand personal bag measuring box is too small compared to USA airlines,

My experience was good with United too But only not so good thing was that at Calgary airport I was not given lounge access despite of flying business. Aspire lounge denied it to me, which was unfair I feel

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

they were super helpful. Agents at the desk got me on an earlier flight and I was able to get home several hours earlier.

This is a great non-stop YVR-MIA. Very comfortable plane, and no transfer through a city that gets major winter weather!

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Air Canada’s problems are not staff related by and large, no. The problem is tiny jets between the U.S. and Canada - yes, believe it or not they are still “international” (just ask our own Mango Maniac in power in the U.S.). The little aisle is compounded by a design flaw of a “dog leg” starting at seat 12. Woe be unto you if you sit here as passengers and attendants do not have sufficient room to not hit you in the face with backpacks. One thing I will say very positively about Air Canada is you still provide pillows and blankets on transcontinental flights to all, not just the elites. Your tiny improperly designed jets are also a problem flying city to city within Canada also. One can only say you remind us of a “Jet Blue” or “Spirit” experience. Also your luggage space is downright Byzantine! We will endeavor to avoid you and use other U.S. carriers, albeit charging more.

Terrible canceled flight and lost my luggage. Flew me to Halifax. Tgat flight was delayed, had to spend night in airport chair.

Better entertainment & food options more may be adding chicken option or on vegetarian side good quality pasta

My seat was not comfortable. Flight was smooth. Regretfully we had two delays before takeoff

Amazing service, with enthusiastic crew members, and some breathtaking views of Vancouver. No IFE though, as it is only a 1 hour flight on a regional Turboprop jet.
