I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

Check in was chaotic with only one counter for business class and first class. The luggage conveyor belt at JFK airport was broken so the flight departure was delayed which made the flight stressful as I had a tight connection. Although the captain said they could make up the delay, they didn’t do so.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

Lost of requested seat assignments. Lost my husband's meal choice

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

Very good trip. Nice clean aircraft. Helpful and friendly crew.

Crew members Grainne and Karen were extremely rude and unprofessional

I am very disappointed in that KAYAK sold me this flight as a business class it was not a business class. It was a regular economy class ticket. This was not Art Linus mistake. It was kayaks.

Crew was friendly and seats were comfortable. The connection however there were no free snacks or drinks.

Our flight from Dublin to Coruna did not exist any more. Apparently it was cancelled in February and I was not advised, nor was I offered any flights for rebooking. Happily Aer Lingus found another flight to another city in Spain that was 500 miles from Coruna; I had to pay for a hotel overnight and a revise my rental car that incurred additional costs, and I did not get to Coruna for another 24 hours. I was not at all impressed with Kayak or Chatdeal or Hertz.

OK overall. Flight was delayed Crew on flight was good

Late late late. Delayed and arrived an hour late for a 1 hour 45 minute connection. Every time. Poor record for this company. I try to fly any other carrier first.

This was the smoothest flight I've ever taken with any airline, including Aer Lingus. Typically, there are moments when I feel afraid, but from take off (miraculously seamless!) to cruise, to landing this was a perfect flight. Thank you!

Poor. Plane left EWR late hence missed connecting flight in Dublin. No pro active info from flight staff on connection, only when probed a couple of lies on where we would dock, and on lilelyhood catching connecting flight. Lies as they will have known our EWR-DUB would be parked furthest away from the transit spit - lying it would be next to the AMS flight.

Fine. Nothing to write home about. The plane left on time, and arrived on time.

Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

I appreciate that I finally got the seat I paid extra for this time. Thank you

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

It would have been nice if American tried to care.

Delayed initially because they couldn’t print the flight details. Poor instruction on delay. When I got on the plane the flight attendant argued with me about whether my carry on would fit (it did, although she didn’t acknowledge that). No greeting (other than arguing with me) getting on or off the plane.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Loved and was pleasantly surprised by the food!! Request Lufthansa to help transiting passengers at Munich (confusion whether to go thru passport control or not).

The flight was comfortable and the staff were helpful and friendly. However, we did not know we were flying PAL until we arrived in Canada, so it was a bit disconcerting. In addition, which port we were leaving from was confusing.

As mentioned before the fact that my paid-for aisle seats had been changed to non-aisle seats is unacceptable. Happily one staff member at the boarding counter did correct it before the flights, otherwise I would have been forced to submit a formal complaint. If it happens again on return flights, I will put in a formal complaint.

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

It was good that our flight left early. It was a nice smooth flight and landing.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

The flight was ok. The seats are so small. The free wifi for members was not an option on this flight. The one flight attendant, older woman with straight white/grey hair, was very rude. The gentleman next to me asked about the wifi since he was a member as well. He stated, accurately, that the option to enter the idea number was not available. Her response was, "I don't know what to tell you" and walked away from him. The rest of the staff was wonderful. I asked another flight attendant about the wifi, she said the free wifi was not enabled on that flight (true or not- at least she was friendly). It was also pretty dirty. When I opened the tray table it had mushed crumbs and there was a dirty used pair of ear buds in my seat pocket. Lastly the air vent above my head was working but stuck so I was unable to move it to face me when it got warm. I fly American often but this really was not a great flight.

My luggage was lost at the airport but American Airlines contacted me and got it to me the next day.

24 hour delays aren’t even heard in 3rd world countries with archaic transportation systems. I’m never flying American Airlines again.

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.

Canceled flight late London to Florence. Help at airport very poor. Treated poorly. Had to sleep in the airport. Lost bags- still do not have them. Horrible. I should be reimbursed!

The seats are extra cramped if you are taller than 5’8! Spring for the extra legroom seats for sure if you have a long flight!

Very disappointed with British Airways. It has been over 24 hours and I still have not received my checked baggage or any proper update. Customer support has been unresponsive, making the situation even more frustrating. Poor baggage handling and lack of communication seriously impacted my travel experience.

All the above categories was great. Seats entirely too cramped.

Flight was good but temp in the cabin was cold.

Departure was delayed leading to late arrival, 25 min wait for a gate. Basically, missed all our connections & had to be rebooted, which was a very long process.
