There was No Flight. Both Kayak and Porter refused to honor my booking. I was asked for an additional 1,300 $ CAD to keep the flight. After several emails to both Kayak and Porter I was ignored. I had to cancel my March spring break plans, dog kennel and hotel. I had to re-book another vacation to Nassau in January w Expedia. I had to re-book a new vacation for spring break. Porter and Kayak both blamed each other and would not work together to fix this. Not cool.

Even tho the flight was a bit delayed the team was apologetic. Everyone was friendly and efficient.

The flight was a little delayed but check in was easy and boarding was quick. Luggage was quickly available and everything worked great.

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!

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.

Much roomer than air Canada! Great flight for the price. No complaints

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

As a first time flyer with Porter I was happy with the service and comfort of the airline.

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

I am writing to express my dissatisfaction with the poor service and unprofessional staff we encountered when traveling with an infant. Our flight was delayed, and the gate staff failed to manage the boarding process appropriately. Due to incorrect, unavailable, or missing 'pink tag' stroller and car seat check-in procedures at the gate, we were forced to board last. Furthermore, the gate staff was rude and dismissive, causing significant distress to our infant. To make matters worse, one of our checked items—an infant sleeper/lounger—was returned to us broken. Given the unsafe handling of essential equipment and unprofessional treatment, I expect a prompt resolution regarding compensation for the damaged items.

We departed and landed early which was a nice surprise. The boarding process was slow.

N Everything was perfect from boarding to assistance to baggage in Tampa

Subpar. The seating on the plane is almost unbearable. We are literally touching and/or sitting on each other which is totally unacceptable and shameful. Pilots and crew was very accommodating and friendly.

The boarding was organized and informative but the plane was tight meaning that you were sitting on one another and extremely uncomfortable. It’s disappointing that can’t have common seating comfort on the plane.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

I was told that they needed to check my bag at the gate and to pick it up at the gate in Richmond. No big deal. I know they can't control the weather, but we flew around RIC for 45 minutes to avoid the storm and were 25 minutes late leaving as well. Once we landed, we were told to go to baggage claim to pick up our luggage. I went to bathroom, paid for parking, and went to the assigned baggage claim location. United flight people came down with us as well. They got their luggage immediately. Next, South West people came down about 10 minutes later. They got their luggage next. We finally got our luggage around 30 minutes in waiting. Was not a wonderful experience. No reflection on Delta, but the ground crew was lousy at best.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

Flight delayed. Air broken. Cabin was hot enough to pass out. Delta shuttle’s becoming worse and worse.

my mom urmila patel needed a wheelchair which was not available on the curbside. she needed to walk almost 50 meters inside (at the risk of falling) and then had to wait in line to get a wheelchair (this is not ok). Once obtained she had to seat in it for 30-45 minutes for someone to take her in thru the checkin process (which was fairly smooth and easy). the lady who helped her with her checkin process was very courteous and helpful

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Ineffective communication with United resulted in lost baggage. Their Baggage Tracing counter at MUC was shut down from 11:00-14:15 on my arrival. Undertrained, underinformed staff had me Running all over MUC to find someone to help me to no avail. Staff was rude, unhelpful, and unable to effectively use the systems they did have operational. They refused to contact United in any way or provide any accommodation or other resources while I waited for my luggage. This has destroyed my downstream itinerary. If they had even the slightest visibility I may have been able to reschedule/plan, but again, their staff provided nothing, and did nothing more than their website, which doesn’t even work on a standard phone browser. Miserable failure at all levels that weren’t associated with the operation of the aircraft.

Sat next to a one year old. She crawled all over the place and made me laugh.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.

Flight boarded, departed and landed on time. Excellent service from flight attendant in FIRST

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.

delayed due to weather. Could not communicate with family since the wifi was broken

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Good boarding but extremely cold temperature in both flights (60 F!).

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

I checked a bag and there was only one agent to assist all customers with any issues.

I want to thank Carlos at the Miami AC desk - he was amazing and went over and above to help us out. Thank you Carlos and all the best to you!!! You made our faith in AC feel great! Sincerely, David Cubitt

Flight was canceled due to mechanical issues. After a considerable wait in the queue, Air Canada customer service was very helpful to get us on another flight. I am disappointed to report our rescheduled flight is for three days from now. Three days of extra expenses and inconvenience is unacceptable.

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.
