Be prepared for a labyrinthine experience traversing the various levels and passages of the Toronto airport. Bring quality walking shoes, as it is likely well over a km in total walking time.

Carry-on baggage sizing for United US bound flights appears to be much smaller than for Canadian flights, which forced me to check my bag at the last minute. So check online ahead of time

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

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

Our flight was delayed by a bit. I appreciated that we were kept informed on why periodically. Boarding was fine. I overheard one flight attendant sounding very rude to a passenger who was not paying attention to the safety demonstration. The snacks were minimal as it was a short flight. There was no entertainment. Overall the flight was good back to LGA.

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

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

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

Excellent experience. Starting with the agent at the Premier bag drop who noticed I was very early for my scheduled flight and offered to rebook me on an earlier flight with my seat preference. She would not let me leave the counter until she knew that all of the changes and new boarding pass showed up on my United app. At the gate, the flight boarded quickly such that we departed early and the flight was smooth. We arrived 20 minutes early at ORD and I was able to be home in time for dinner. One of the best flights I've had.

Salina to travers city was great! But the sept 24 Tranverse city was not! Traverse city to chichago was cancelled, i went to Denver & got to Salina 6 hours later!

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Could have said yes to a glass of wine 🍷 instead of saying we'll come around in a couple of hours

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

Inoperable monitor left no entert for 9 hours. Crew was not helpful Food was awful.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

Flight, food and crew were all good, friendly and very satisfactory.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

Premium economy seat was decent. As always poor headphones, poor food and beverage, crew is not overly friendly

Excellent - explanations were clear staff was nice and flight was comfortable

Lost bag and 2 days no word leaving for cruise no clothes or stuff

The flight was on time and crew were nice, seats were tight and there was entertainment available

Good service, friendly staff. Food was average for airlines and the seats were small.

There is no snack and nit much that would be considered gluten free in yiur food selections. One of your snacks should be a gluten free cookie or small bar etc. maybe it was me but I didn’t see any free movies just internet connection and YouTube .

I like how spacious the plane was but I did not like the fact that there was no entertainment

No dogs! Can we have no dogs in the cabin? Why was there a yappy little dog behind me? Lucky I had ear plugs. Sorry for others without

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.

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.

Flight delayed, missed my pick-up had to Uber, plus missed dinner and medication, so sad!

Nothing to like because my inbound flight was cancelled without notification by West Jet or third party, JustFly. I couldn’t take the inbound flight due to cancellation; therefore could not take the outbound flight back.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

First message when all on board was that we didnt have a pilot, then they found one, then it was something about the bridge something not working, they will either fix or do manually. Flight of course was leaving late with all the cruise guests worrying about making it to their ship in time. Then only some luggage made it off the ship. Around 15 to 20 people waiting. 45 min later arrived except mine. I asked the rep at the luggage conveyor, he asked me my name. Then said it was not picked up with the first batch so they put it in a room. I was going to take public transport but now worried about time so took a taxi that cost me $65 USD

The flight was very smooth and good. Boarding was fast, but the staff was just decently friendly.

Air Canada flight staff are in contact negotiations and they are less than happy and it show. The process of self checking baggage is less than desirable with lack of support staff to help

A sandwich and a drink would have been better thank a snack bar...

I liked the behaviour of the crew members.The flight was good.

I swear airplane seats keep getting smaller and smaller but everything else was great. Smooth sailing and we got in early.

No food to provide, they forgot that, in some cases, people stay at the airport for hours without food. Now, to provide them with food, they have to ask them to pay, because some don't have money. That way, they can't eat.

After a long flight from Tokyo, our connecting flight home was canceled due to “maintenance” while we were on our layover in Toronto. Very frustrating to close out our honeymoon, although I’m sure others had it even worse during last week’s strike. Air Canada staff at Pearson Airport are the one thing that kept me remotely at peace during this — they were very helpful and deserve a lot of props. But I would not fly Air Canada again.

Horrible flight cancelled had to buy another very expensive ticket
