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. .

Boarding required going up and down the stairs with your carryon bags which wasn’t an issue for us but would be quite challenging for elderly people, or anyone with mobility issues.

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 helpful in getting us off the plane first to make a tight connection.

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

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

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?

Excellent service, full flight but all went well ; slightly delayed start at Faro but arrived in Cork on time.

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.

Seats were less comfortable and tight from Newark to Dublin, than my second flight ( small segment from Dublin to Lyon). Movie audio was with frying sound overall. Yet the worst was as follows: one male, (dark hair , glasses on) from the crew member was so cold and rough, while I remained with constancy polite and kind. Per exple with the noise level I could not hear him at first for beverages, he rolled his eyes at the third times I finally heard him. From the start, loading my small hand bags , he directly spoke to me and said “ I had to keep my shopping bad by my seat, under , while there was sufficient room and I was among the last to sit. I show him the space , his face was always dull, stoic, not welcoming as the usual crew members from any airline companies are. When I think of my experience I liard w Aer Lingus, this is the image that gets back to me. Needless to say that as a passenger and client, I felt belittled since all this happened in front of the surrendering passengers. It s an affront and not a pleasant feeling especially when being traveling which oftentimes involves stress with carrying, and making it on time. I m not happy with the experience I had to be honest and I fly four times a year. Thank you for allowing me to share this statement with your company.

The flight was delayed by about an hour, but the staff and signs at the airport never actually said it was delayed. At the expected boarding time, we were told we would be boarding in about 10 minutes, then 20 minutes passed, and were told again that we would board in about 10 minutes. That happened multiple times, such that "10 minutes" turned into an hour.

The seat spacing was good. The food, not so good... typical airline food. 😕

It was fine. We were delayed leaving but a situation of too many planes, not the airlines fault.

One cold drinks service. No snacks with drinks. No tomato juice or apple juice, coke - only fanta or sprite then ran out of that. Went to gally after meal service no one there / no self service for water at least. Waited 25 min for cabin crew to assist. No recycling of cardboard/ plastic - all put to garbage. Breakfast was a nutrigrain bar and an orange juice. Also I'm sure I booked a flight with checked luggage allowance but had to buy extra when I had my booking confirmation. Movies were good. Chairs comfy. Pillow and blanket and ac vents.

There was no room in the seats, smallest room we've ever had and the food was awful.

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.

For a four hour flight, I was disappointed that everything was for purchase except for coffee, tea, or water. The disembarking in Iceland was so inefficient and time-consuming. We landed and stopped in the middle of the tarmac, had to disembark in the rain, and then squeeze into a bus which took us to the airport. Crazy! How does that work in winter?

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

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

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.

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.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

The flights were in time and the bags arrived. well done

The airline was efficient and accommodating to work with though there was a delay. Appreciate the service and smooth experience!

Flight was good but seat in 12D was not comfortable, better on the Airbus 321 from Tampa to Charlotte. No breakfast was served before landing in zLonfon only a coffee and orange juice.

I was transferred to an American Airlines flight. The boarding was late and unorganized. The seating was extremely tight and uncomfortable. Will not use AA again.

The entertainment selection was ok, but overall not bad! The crew was great.

Good crew and boarding process. Horrible food and one of the most uncomfortable aircraft seats I have ever sat in. The cabin temperature was warm which made it hard for my family to sleep.

bad, made it to connecting flight and they didnt let me board

We were never able to take this flight because our first flight from Austin to Dallas was cancelled.

Our flight was cancelled on Sunday morning. We were supposed to take a short flight to Dallas from Austin, then a nonstop to Barcelona. We were rerouted from Austin to Miami on American Airlines due to storms we sat at the gate for 2 1/2 hours, pilot announced we needed fuel. In air pilot said we were rerouted to Fort Myers 30 minutes from Zmiami. Sat on tarmac waiting for a gate. Deplaned at 10:09. Pilot gave conflicting info about what to do. Missed Miami flight to Barcelona. Pilot announced crew was timed out and we would have to wait for a new crew. Waited a couple of hours. Got to Miami at 2:30 am. Gate agents at Fort Myers told us to go to D30 for hotel vouchers. No one was there. So we slept a little on the floor. Husband is 80 and I am 74. Rerouted to JFK at 9:54 am on Monday, then flight to Barcelona at 5 pm. We arrived in Barcelona a day late and missed the first night of our Oceania Marina cruise. We feel that we are due a lot of compensation for this trip from hell.

The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?

More Indian vegetarian food options would have been better Availability of seat selection free of charge 72 hours before departure would be great

Seats were not comfortable, and the problems started when we landed at Frankfurt airport. We waited more than 3 hours to collect our luggage, as a result we missed the connected train to Brussels. Our plans for the trip were ruined that day.

I missed my connection in Frankfurt and was booked to another flight to New York. Different destination and got downgraded from Business Class to economy. No Support from Condor at all. Very Bad experience

Flight 1.5 hours late; missed connection. Ground support for rebooking inadequate to the point of ridiculousness.

Flights delayed, and not communicated to the level I accustomed to by other airlines. The crew seems to be hating their job and it shows. It costs you nothing to smile and be a bit more friendlier. Also, no jet bridge, passengers have to use stairs, which is hard for my elderly parents. What's the point of ordering wheelchairs?

One of the stewardess was really rude to a customer right near me. I ordered water and was given sparkling water which kind of surprised me as I've always been given still water but I didn't say anything. The lady after me ordered water as well and when she saw it was sparking water, she stopped the stewardess who then said very curtly "You could have told me sooner." Whoa...that was rude! Later this same customer had some liquid spilled on her as the same stewardess handed a drink to the person sitting next to her. I know it wasn't intentional, but it was rather strange. It was very hard to navigate how to get through the Frankfurt airport to our connecting flight. No one told us you'd have to go through security again so it was rather confusing as we didn't have a boarding pass. Luckily we were able to get necessary papers and get to our flight. Sadly, my luggage did not make it out of Frankfurt though.

Quick easy flight, checked my bag and was told to pick it up in LAX but my bag stayed in Frankfurt. I am tracking it with an air tag. I filed a complaint with Alaska Airlines at my last stop in SJC.

The crew was friendly, but the comfort of the plane and the food definitely had room for improvement.

The cabin staff was very friendly and attentive. The plane was modern and fairly quiet in flight. The video screens are large and of high quality, and I liked that the documentary movie "Anselm" was available for watching.

The flight from Saskatoon to Calgary was canceled by WestJet due to the airline strike. Condor, as the main operator, did not inform us. We found out that information just when we arrived at Saskatoon airport. Fortunately, we had enough time to drive to Calgary airport and catch the flight to Frankfurt. We couldn’t claim compensation for the missing flight because nobody takes responsibility for this situation. When we tried to contact BudgetAir, they redirected us to Condor, and Condor redirected us to WestJet. WestJet keeps saying that they are not responsible for the ticket that was bought from a third-party company.

Because of luggage I had to upgrade to premium economy , which was worth it!
