Airline reviews

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.

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.

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

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.

All good the seats a little tight and no I pad screen

Just an evening before they canceled my ticket and offered me ticket costing 3 x times more than. I will not fall prey to these scams,Will never book through kayak now. Such a bad experience.

was okay except.. 1)the porter check in webpage doesn't let you print your boarding pass from home 2)that there was a 90 min cut off for checking in on the kiosk in general, and to print a boarding pass, even tho i checked in online already....

It was amazing although they did bump us up to the front which gave us more leg room and a meal. The service was great! The staff were friendly. :)

The flight was delayed by more than one hour. The terminal was consequently overcrowded and hot. We lost our car reservation and hit rush hour traffic in Boston, which added two hours stuck in traffic to our trip.

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

Friendly crew, but we were delayed for more than an hour and had to change planes due to maintenance issues.

Prefer not to have an almost 3 hour delay with useless communication that wasn't accurate.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Crew were welcoming, accommodating and they worked hard to find places for all carry on.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

They were fast and I like how they used to entertainment system to play video about the safety.

Delay, after delay, after delay. It was hard as an adult travelling alone. I felt bad for the families with young children to entertain for several hours. Agents and crew performed to their usual good standard. Air Canada, never again.

Lovely flight.....only cold drinks and no more complimentary cookies!

It was good. Short flight and the crew were well organized. I find the seats a little close together. I am tall so more leg room would always be welcome.

Would like whole can of pop for 2. Treats were not great . The garlic pretzels were terrible for someone who can't eat garlic. Passenger was 84.

Everything was great, clean plane and washrooms. Flight was on time, excellent boarding process

Seats were comfortable, flights boarded easily, arrived early in Toronto and on time in Nassau

My flight was delayed for more than 18 hours no accommodations was provided spent the night at the airport

I flew twice this vacation with air canada and I don't know if I would ever book again with them, the flight attendants were very nice and apologetic but the delays were horrible first flight was 7hrs late and the second was 1hr late

My flight from toronto to tampa is delayed for more than 3 hours.

Unfortunately all flights were delayed. Flight to Moncton was delayed 3 hours and my family who was picking me up from 1 hour and half outside the city had to get a hotel room for the night.
