I wish I had anticipated the delay at the airport and scheduled my ride pickup for 1.5 hours after the estimated arrival time. I was unaware that passengers from Air Canada flights had to board a shuttle bus to access the aircraft.

Make sure you know which terminal to head to upon landing if transferring at Los Angeles as the information board at LAX will show only flight info for the terminal you are at (1 of 8). Transfer information is not transparent from the airline or the airport. Subscribe to airline apps help but can be cumbersome and difficult to manage in a time crunch.

Maybe get the choice above the cheapest option because you don't get a checked bag or carry on so in the end you end up paying about the same, if not more.
Verified travelerFlew with Air CanadaYYZ-LAXAug 2024
It is great to have a nonstop flight. Might be worth paying a bit extra for it.
Verified travelerFlew with Air CanadaYYZ-LAXAug 2024
Treat this like you’re flying on a greyhound bus. Bring food. Bring a pillow. Bring entertainment. Know that you will be uncomfortable and the airline won’t care.
Verified travelerFlew with United AirlinesYYZ-LAXFeb 2024
Do your check in online because it is much more convenient.

Get instructions on how to find your connecting flight terminal and gate in LAX. There are no information boards or information desks. We asked a lady in a gift shop, then it was a series of tunnels and stairs that were not well sign posted at all.

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.👍

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.

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

Our flight was cancelled at the last minute for maintenance reasons and we were rebooked on a late flight when we purposefully booked our flight to be home early due to work.

I did not like I have been charged for my carry on

Very good. A lot better experience then I expected for an economy flight.

It was very good but no tv but the experience was great

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Nice complete meal included and great services. Plus the plane was very clean.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

Quick and seamless boarding. No entertainment but fast Starlink wifi for this short trip and the staff was really friendly.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

7 hours delayed due to operational issues on United’s end. Basically laziness.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

The food quality sucks. One must starve if they do not eat flesh Or wheat based products Some variety would be expected. The trivial amount of snacks and or food is inhumane

Efficient all round, very good crew. Short flight so the food, of course, was just snacks

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

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 when to Jamaica for my dad funeral and I did not get my luggage from westjet . I add to buy clothes putting me financial debt i did no want to be in Westjet did not call me to apologize are to inquire about my luggage I am still angry about it

Ground staff was not helpful, but staff at the business counter were excellent.

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.

We landed 26 min early. It was awesome! Smooth ride too.

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.

The staff at the airport and on the plane were wonderful I especially wanna acknowledge the staff who boarded us at the Calgary airport. The women who helped us board at the airport were incredible… they were so kind and sweet…I very happy with WestJet and I am hoping I can fly more often to Canada.

The staff was great and made the long trip easy peasy!

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

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

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

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.

Flight was cancelled last minute. Had to scramble and purchase a $2000 flight through a separate airlines. Stuck in Toronto two extra days. Missed my first two days on a new job. Had to rent a car for an additional two days. Scrambled to fins a place to live those extra two days. Spent a ton of extra money and lost a lot of money, as well as made a poor impression at work. Difficult difficult difficult

Terrible, return flight was cancelled a night before the flight was scheduled to depart and I was notified by an email and an automated message on their phone line. I’ll never book Air Canada again

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

Ensure prepaid food arrangements are appropriately understood by flight crew of who purchased and who did not

Terrible all around. Flight was late and airplane was very uncomfortable. The crew were unhelpful and hid in the back. Did zero work. No entertainment.
