Only one choice for meal seats had no leg room

6.0 GoodMarek, Aug 2025PRG - CPH

Only one choice for meal seats had no leg room

Will not recommend SAS for business travel. Food was so-so. Service was very good. First leg was very good. Second leg from Copenhagen to Barcelona was terrible. We paid a LOT for business class and to have seats worse than most coach seats with no entertainment and no charging available for 1/3rd of the whole trip was not acceptable. Very disappointing. I thought they were coming back in the U.S. with style, NOT YET.

I do not have a problem with the airline but both my two suitcases that were supposed to go from Hawaii to Copenhagen didn’t get on the plane in Seattle. I arrive on Monday the 21st at 10:30 in the morning. I did not get my two suitcases before Friday late afternoon that is unacceptable.

No choice of food. Needed to pay more even for a can of coke!!!

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.

When my flight was changed from delays they were quick to rebook me.

I really enjoyed how clean and big the aircraft was, as well as how friendly the crew was.

The Recaro seats are stiff and have minimal padding. Quite uncomfortable for a 5.5 hour flight. The upfront seats and space are identical to the ones in the back. The upgrade was not worth it.

Airline left me stranded in the U.S. gave me an unrequested refund of 40% of booking and canceled my trip back! When I asked why, the said “we don’t have to tell you why”. “But you can rebook”. Never again! Paid 2x and rebooked on Austrian. What a joke!

Painful seats for a 10 hour flight. There’s a very hard flat board in the seat that goes up to half the back and after 7 hours it gets impossible to find the right position to avoid the pain.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

It was delayed instead of departing at 9:20pm, we departed at 11pm… putting us in Columbus after 2am! It was awful. Had I known about the delay, I could have spent some time in the United Lounge… I was starving because I started my journey in Budapest… so I was exhausted and hungry. Plus I had to make new arrangements to be picked up at the airport in Columbus, instead of midnight it was 2:30 am after getting luggage and out of airport. Not feasible. I would have just stayed in Chicago for the night and gotten a morning flight.

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!

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Terrible leg room - I’m 5’3” and my knees were touching the seat in front of me. When the person sitting in front of me leaned back, there was about 15 inches of space between my head and the TV screen which made it awkward to view movies. Last year they had decent food, but this year the only tasty item on the trip was dessert.

The flight was delayed leaving Philadelphia due to “catering” and consequently arrived in Dublin some 75 minutes later than scheduled. Consequently this caused me to miss my connecting flight to Glasgow and I had to spend the night in Dublin.

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

Horrible. I had to wait in Dublin for 4 hours for the next connecting flight which took my to London and than i had to wait 3 hours for the flight to Dusseldorf

It was truly a horrible flight. We were delayed almost 2 hours. The seats were so tiny, my legs were hurting the entire flight. When i finally made it to Ireland i missed my connecting flight because we left Newark late. I will most likely never fly Aer Lingus again

Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

Terrible. The test of an airline is how they deal with problems. There is very little to differentiate between airlines. Aer Lingus failed absolutely. They lost one of my bags even though we had more than a 2 hour connection in Dublin. Trying to get it back has been awful. In checking on line I can see that the bag is in Edinburgh and it was supposed to be delivered today. It wasn't. The number we have in the UK doesn't answer. I had to pay for an international call to speak to somebody. All the woman at the call centre could say was be patient wait. I can tell you when it will be delivered nor can I tell you who the courier is.

A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

Seat was hard and uncomfortable and the temperature too warm and uncomfortable.

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

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.

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

The plane was delayed by two hours in Chicago which led to us missing the next flight. Lufthansa rebooked the flight and booked us a hotel for the night in Frankfurt. The level of customer service and getting us taken care of was superb. The flight crew and the service on the ground was superb.

good entertainment package but rather small seats for business class

Booked Economy but it translated to economy light for Lufthansa so now we are stuck paying an extra $75 per person both ways for our checked bags. If I had known that, I would have never booked these tickets because it came out to be more than other options. The booking in the kayak side clearly says Economy and has a link to the inormation for Lufthansa which states Economy included a checked bag. Super annoyed about that.

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

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 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
