Didn't care for the crowding at the gate area at SEA TAC. Not a fault of the airline.

Didn't care for the crowding at the gate area at SEA TAC. Not a fault of the airline.

Loved the staff ease of flying snacks and free movies and WiFi

you could have gotten me there on the day I was supposed to be there, not a day later. Paid for 3 nights at a VRBO and got to spend only 2 nights there.

Flight crew and gate staff were very polite and professional. They were very helpful and made my trip smooth and trouble free

Our flight was delayed BY 6 hours and the reason it was delayed because they needed a part which made me be worried about the plane. They did not have any TVS. Add the seeds and this was a very long flight. But they also only offered snacks, and even after we waited the 6 hours of being delayed with that, we still have to pay for drinks. If we we wanted one

all crew, pilots and attendants were fantastic. Both to and from flight to SEA, attendants went above and beyond.

Late boarding, but the flight was smooth and the crew was accommodating.

I requested wheelchair assistance in Seattle transferring gates and in Anchorage to get to baggage claim. No assistance was provided at all.

I was totally disgusted at the stewardesses supplying the three passengers in front of us in the exit row with multiple rounds of booze. They were loud and inappropriate using profanity to share stories. Our 3 and 7 year old he’s d it as well. Just flat out inappropriate and amazed AA wasn’t implementing a drink limit policy.

Arrived in Seattle to find our non stop flight was canceled and that we were rebooked to depart 16 hrs later. We stood in customer relation line for well over an hour and a half to find out what to do with our frozen fish that was checked bags and to get to our destination in a more timely fashion. There were only 2 Alaska reps working trying to help at least 2 cancelled flights that we know about. At one point a 3 rd rep showed up and shortly after one rep left stating she was going on break. There were atleast 50 people still in line. Finally We were rerouted through a different airport adding another stop the next day and given flight confirmation but no seat assignment stating ticket vouchers needed to be attached. We were then told to go to Alaska air luggage to request our fish be put in the freezer. The supervisor at baggage told us the freezer was full and that there was nothing he could do about it. Luckily he walked off and the ladies at the counter made sure our fish was put in the freezer. The following morning we had to be back to baggage to make sure our fish was tagged appropriately to get to our destination on a separate flight. . Both of our return flights we had to take we had to stand in line for the ticket people to try to find our ticket vouchers to attach to the boarding passes we were given. Al together our return took 31 hrs instead of the 12 hrs scheduled.

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Flight was delayed and missed my connection Lufthansa didn’t respond.

A little bit more leg room in premium economy. I am 6’4”.

online check in was not available so i had to get to airport extra early. The flight was delayed and my luggage was lost. I had an argument with the person behind me who wanted to keep her bag on the floor and not allow my seat to recline on a 9hr plus flight. So overall, lots and lots of areas for improvement.

The flight was operated by Lufthansa. You can't expect much from them anymore. They have a talent in getting something wrong.

The food was the worst I’ve had on any flight I’ve ever been on.

The seat and leg room was not good. The food and beverage service was good.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

Food is terrible. Flight is outdated and seats are not comfy.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Great experience on Icelandair flight from Newark to Amsterdam by way of Reykjavík. Courteous and professional staff. Food was solid. Service - outstanding. Cabin was a little warm.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

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.

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

We were upgraded to economy plus and everything was awesome!

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

Hate their old flights, boatding, food and services. Very poor quality

The food could be better, more snacks. And have some plugs to chargue the phone.

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

Everything was really great just The aircraft was too old and sounded it will break during takeoff

Flight was a little late. The crew was courteous, food ok

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

Helpful crew in a comfortable and well designed aircraft. My kids also loved the striped design of the airplane.

The return flight, the food was better. Didn't like that even at checkin we still had to pay when only 5 seats were available. Had to pay or would be stuck in the very middle between two others. I had to pay for an aisle and a middle seat. Both were considered prime seats but the two other middle ones were not.

There was one flight attendant who was exceptionally rude about the fact that they didn’t have any meatless options left when I told her I was a vegetarian. The boarding process was a bit disorganized and unclear but everything else was very good.

Seats are not comfortable. Some of the food was good and some not so good.

Really, nothing. I flew economy, and received a very good economy experience.

Flight attendants were polite but not attentive. They did not clean cabin throughout trip, and the airplane upon disembarking looked disastrous! Garbage everywhere ! The state of the cabin did NOT leave passenger with a ‘cared-for’ feeling. It looked a total mess. They also closed themselves off in the back of the plane and passengers felt like they needed to knock to get a glass of water. Very dissppointing.

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?
