If you’re flying through New York, LaGuardia Airport is night and day compared to many older airports. It’s clean, spacious, and has plenty of food and beverage options. I also found both drop-off and pick-up to be very easy and efficient, making the overall travel experience much smoother.

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.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

The plane was old and thus the seats were not good. No cushion left whatsoever, and it all was a bit worn out.

The flight was late which i understand happens. But we flew Delta one and the Crew was stiff and not that friendly. They didnt offer beverages after they served the lunch. I dont usually do reviews but i felt i must tell you about this crew. They were american not european. We are platinum members and we are usually treated much better

After I checked in, I realized we had no seat assignment. It said they would be assigned at the gate. This was really frustrating because I usually use a lounge before flights, but I couldn't because I had to be at the gate to ensure we got our seat assignments. The gate agent arrived an hour before the flight left. I was the first one up to ask about seat assignments. She told us to wait for names to be called. Dozens of other passengers were paged, but we were not. Finally, I asked my husband to ask. He went up and was also told to wait. About 10 minutes later, they called for boarding. We still had not been told our seats. We went back to the desk and they were in a panic, saying we actually weren't on that flight. Then they made an announcement telling the stand by passengers to not board (in case we needed their seats). It was so stressful and unprofessional. Finally they gave us our seats. I have no idea what happened and why the two desk agents seemed to have conflicting ideas about our seats, whether we were on that flight etc.

Very dissatisfied with the fact that I had upgraded to first class for the second part of my trip only to find out that the lounge was still not available to me, as well as not having any food or drink service on the flight due to weather, so I lost out more than what I paid for.

Overall it was not that bad! The delay on the second leg to Indianapolis , was really unexpected!!

It was very good. Our flight was delayed and we as a result missed our connecting flight but rescheduled to the next day. The Need Help staff was so great and offered us compensation that was beyond satisfactory.

Excellent. No issue and it was on time and arrived early, the best!

The flight was oversold and they kept on announcing they were looking for a volunteer to give away their seat, but the announcement has to be louder and clear @ gate 88 and also must precise. Additionally, the departure time kept on changing. But overall it was fine since it was a short flight.

I received the two differed meals: chicken and pasta. I asked and I received. I am anti-wasting food!

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

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

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

There was no room in overhead bin to place our luggage despite we had tree seats. It means a lot of people had more than 1 carry on bags. When I asked a crew member to help she said that it was not her responsibility.

Very bumpy flight & the crew was not happy to be there

Air conditioning was out for about 15 minutes that made it uncomfortable. WiFi went out halfway into the flight. Flight was about 45 minutes late.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

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

A cookie and a soda, packed like sardines, will never be a positive experience. Also, boarded a 5:30 flight at 7:45pm

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

Due to the long delays and rescheduling boarding was horrible. However, the gate staff and the flight attendants went above and beyond to remedy our frustrations. They were able to handle every potential harsh situation with Grace, compassion and coolness of head. Kudos to the MIA Gate A12 and night crew of flight 1572 YYZ to MIA.

I liked nothing about this particular flight. Not only it was initially delayed for two hours due to late arrival of the plane, but the flight attendants were also very late to show up coming from a hotel (based on the announcement made by the gate agent). They did not arrive on another late flight, so why couldn't they be on time? Total disrespect of the passengers!! The plane itself was cramped and the seats super uncomfortable. To top off the poor experience, my video screen did not work. To summarize: flight delayed for 3 hours, cramped and no entertainment (for me).

They kept posting delaying flight due to maintenance issues from incoming arrival flight since 10am, the flight is supposed to depart at 3:45pm, after kept delay until 12am, they finally said it’s canceled. What were they doing for the last 13 hours? After 2am, they still don’t find hotel where we can stay. terrible experience!

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

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

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

All was fine. Weather was a bit stormy, but nothing kayak can do about that! 😊

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

Announcement of flight cancellation when we were at the gate for boarding. Yelling that the only thing they would do is hand out taxi or hotel voucher. Group of us were travelling to the same location and we were not accommodated to travel together. I was sent to Montreal with barely enough time to make connecting flight and when I got to La Guardia my luggage was sent to Newark. I got a damaged suitcase next night (after 11 pm).

5 day of cancellations and errors. Several days due to weather and several due to broken planes. Nightmare

Terrible. Flight in the morning was circling in air for 45 min due to weather then rerouted to a location further than the final destination to refuel. Sat on tarmac for almost 2 hrs to refuel. Flight was originally to land at 9:30am, we arrived at 2pm and then waited another 30 “for an agent”. Then afternoon return flight was delayed again 3 times for weather then cancelled. Auto rebooked was for the next evening! Just miserable.

It was great. They always say active military, may board early. What happened to the career military that retired with decades of service. Besides that always great experience.
