It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

Delay and keep changing gates. I have to run around from B to C then to E.

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

Flight was great. Efficient boarding. Short flight. Early arrival. Friendly flight crew. The entertainment system did not work well. Could not access it until the aircraft reached 10K feet or more. Lots of glitches.

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

Everything was very good, except that the plane was an hour and a half late

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

Light and recline did not work on my seat. Very uncomfortable and could not read in the dark

Bad experience; they are not good anymore. They charge too much for luggage seat are so uncomfortable, Flight delays which may miss your next flight, they don’t care if you miss the flight or not. Zero customer services for front desk representatives Istanbul's airport I’m not using this airline any more.

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

I paid for the seat with more leg room but on the day of my departure my seat was changed. I brought it to the airline costumer service and he was able to change it back. The person sitting next to me had the same exact issue.

Great experience. Typically do klm to Amsterdam but may start taking this flight in future - greatxexperience.

The food was wonderful! The blankets and pillows were a nice touch and the staff were very accommodating, making frequent rounds to offer food, drink, etc. We were also told in advance when to expect meals to arrive, which is thoughtful. I liked the early notification about the lack of headphones as well, although unfortunately I'm not sure we received on for the first leg of the trip, which would have been nice to prepare for. The seats are a bit tight, and the bright monitors on the wall were on during an overnight trip, making it difficult to sleep for those close to them. .

The check in not ok! Demanding that we check our carry ons on check in! When there was plenty of available space inside the plane! And the staff at check- in was rude and not helpful and I was traveling with my autistic son and his service dog! Boarding was easy since we were priority boarding! The crew was ok expect from one guy flight attendant that was actually great!

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Standard short hop flight. No food, no entertainment. Just get in, get something to drink, and try to be as comfortable as you can for an hour.

Cancelled my flight. Only option had a layover in Italy. No compensation for the 4 extra hours of travel time. The travel agency, cheapflightfares, blamed Scandinavian airlines and said there was nothing they could do. Scandinavian airlines said since it was booked through a travel agency there was nothing they could do. The entire thing was incredibly frustrating. Never booking through kayak or with Scandinavian again.

Very unfriendly approach to me when you rescheduled my return flight due to your delay. No help to address my health concerns because I am diabetics and had orthopedic problems. No clear explanation where to clear customs. I had poor customer service

The seats were really cramped. The high backs on the chairs made you feel claustrophobic.

Maybe more diverse entertainment. Although the inflight cameras were amazing 10/10

It was excellent! The plane left Chicago early. Arrived in Dublin early. The crew was excellent! It was a great experience.

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

The Nice airport was a horrible boarding experience. I have never experienced the kind of compressed mob (in the B12-B17 gate area) of people all unclear what was happening and no airport staff to assist. There was no signage and 1000’s of people waiting for any info for 2 hours.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.

Flight was on time. Boarding was quick and efficient. Seats were comfortable. Food was fine.

Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?

The ease of boarding was good. I wish they had something to eat on the plane.

The check in process at CDG was absolutely unacceptable. We arrived to the airport 3 hours and 20 minutes before our departure time, waited in line for 1 hour and 30 minutes to check in (despite having checked in online and only needing to check a bag), then were forced to check all of our rolling luggage despite the fact that all were compliant with carry-on requirements. The staff at the desk were rude and there were only two desks open, while eight people were working. The check in desk wasn’t even opened on time (3 hours prior to departure) and there was no communication about when it would open or why there was a delay. We feared missing our flight because the departure board was not updated, so rushed to our gate to board once we were through security because it was 20 minutes prior to departure, only to wait another 30 minutes before boarding even started. Communication was lacking throughout the process. What a horrible end to our trip.

Still one of my favorite airlines, but the entertainment options were a bit lacking. It didn't help that my screen didn't work on one of the legs of the trip.

The plane was very small and the aisle was so narrow that every time someone walked by they rubbed against me, so it was very uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.

Paid for a Premium seat...minimal recline, no footrest. Maybe slightly wider than a cheap economy seat. Zero chance of getting any rest on this plane

Seats in premier saga class were narrow and hard. Very uncomfortable for a 5-hour flight.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

I had an exit row and so was Comfortable on the long flight.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.
