Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

My American Airlines flight was deleted and you guys never let me know

The entertainment system did not work. And we waited 45 minutes in our seats after we landed before we got to the gate

It was a pleasure definitely going with Iberia on my future travels

Our connecting flight was cancelled and it took us 15 hours to reach our destination.

This has been the worst experiencia I have had traveling overall. More than 3 delays, no one answering questions, no one at the AA counter. No one at customer service and after having to change transportation to airport and spend the night at a hotel paid by me, we were delayed inside of aircraft for more than 2 hours!!! Bad experience!!!

LAX to Copenhagen was very nice…business class…great service and comfortable seats…great value…Copehagen to Barcelona…business class was normal coach seating…a little cramped…box meal….good service

Had recurring problems with the touch-screen entertainment system repeatedly making up inputs, resulting in the movies randomly jumping forward and backward. With the lack of proper controls, it was also difficult to get back to where the movie was up to. These phantom inputs were so comprehensive that the system even changed the language setting. Despite a schedule 6.25pm boarding time, it was announced in the Delta lounge at 6.15pm that boarding for the flight had started, so of course everything started to head down. While the gate continued to show a scheduled boarding of 6.25pm, it was 6.32pm before boarding actually started. No, not significantly different, and we ultimately ended up landing well before time (and landing time is arguably more important than exactly when boarding starts). Seat comfort was fine, although only a small nook for personal items, food was satisfying for me, and crew was pleasant.

Staff was fine. But plane offers very few free services.

Entertainment system caused delay. But order was restored within one-hour into the flight. Service was good.

I did not go. I rebooked my ticket. Despite that you keep sending me emails and now this survey about a trip that you should know by now did not happen. Very bad, impersonal customer service. Shows you have no idea what's going on with your customers and that you're just spamming with automated, careless communications

It was my wife and me traveling together. We purchased more expensive Economy Plus tickets, but the seat selection was not available, although this was the main reason for buying the more expensive tickets. When I called SAS, I was told that the seats could be selected once check-in is open, i.e., 30 hrs. before departure. On the inbound flight, I could check in only the first leg (Boston-Copenhagen) but the system would not allow me to check in for the connecting Copenhagen-Split flight. On the return flight, I was not able to check in and, therefore, select two seats together at all. I even received an email from the SAS stating that the check-in was open but when I attempted to do it, the system would not allow it. Trying to get help by calling SAS customer service was no help at all. Although there are signs at Boston Logan Airport implying that there is a Scandinavian Airlines lounge, there is not one. We were sent to Delta Priority Lounge where we were told that it is for business class passengers only, although the terms of Economy Plus state that the fare includes access to a lounge. The seats and the legroom were no different than standard economy cabin seats. On the flight to Copenhagen, my table was broken (not unfolding completely), so I had to hold the food tray with all the food in one hand while trying to eat with another. Overall, it was definitely not worth it paying for the Economy Plus tickets. Based on my overall experience, it is very unlikely that I will consider flying SAS in the future.

Flight delayed 3 hours 45 minutes. Connecting flight changed. Would have missed cruise ship. Had to cancel return flight, because we couldn't just cancel flight to Nice.

The flights from EWR to Stockholm and from Copenhagen to JFK were great. Love everything from SAS

First off, numerous things were misrepresented. When we purchased the Economy Plus tickets the fare allegedly includes access to lounge. At Logan Airport where the signs points to, there is no longer SAS lounge. We were directed to Delta lounge, which is located at the other end of the terminal. When we got there, Delta reps told us that it is for SAS business class passengers only. The advertised seat selection 30 hrs prior to departure did not work online. When I called SAS, they told me that it was more than 30 hrs before our connecting flight in Copenhagen, although it was less than 30 hrs before the departure for Copenhagen. Customer service representatives would not provide any assistance. The tray table in my seat was not fully unfolding to be able to place the food tray on it. Therefore, I had to keep it on my laps.

When we arrived in Bergen and opened our suitcases, we were shocked! We checked 2 of 3 suitcases and the contents of these 2 suitcases was completely wet!!! It was raining in Oslo and Bergen, but not a hard rain. It seems that someone had gone through our suitcases. There was even sand in the suitcase such that everything had to be laundered when we got to Bergen! We had plastic bags in our suitcases and they had been opened and the interiors of the bags were wet!!! Our valuables were all in our carry-on so nothing was actually stolen. What happened here was unacceptable! There is someone working for Scandinavian Airlines who is not honest and really messed things up for us. Not so sure I would fly SAS again… Marna Skaar

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Golf Bags never made it on the flight. Very expensive golf bag and. Clubs,shoes, clothing. Will file a claim against Aer Lingus

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

Delayed take off but I think they waited for passengers.

I had to fly United where the flight crew was atrocious

Flight was delayed for no reason and I missed my connection. This added another day of travel and I missed an event I was traveling home for.

I traveled with my sister, however ,we booked a flight separately, and we don't sitting next to each other. The staff on the board where on the top of this unit they find us sitting together. Ty lufthansa team. U are the best

Courtesy of waitress. Could improve on time management and check-in

Other than the delay of flight, this crew tried to make the best of bad situation.

Terrible. Super uncomfortable/less room than a domestic flight and flight was 9.5 hours. Food was terrible. Flight attendants slammed the cart into 2 people in our party numerous times as they were both over 6' tall and sitting in the aisle.

The wi-fi wasn’t working on the flight from Munich to Chicago and I’d already paid for two devices before they notified us not to purchase it. I think that should have been mentioned as we checked in or boarded not once we were already on board during the safety brief. The flight attendant stated that we’d get a voucher, but we didn’t receive anything while on the flight, so I don’t know who’s responsible for issuing a voucher or refund.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

The airplane did not offer standard outlets so I was unable to work on my laptop. This is totally unacceptable for an international flight.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced

Horrible food and uncomfortable plane. One toilet was out of service.

Business class is fantastic! Lie flat seats, great meals, privacy, and lots of nice amenities!

Flight to Seattle was fine. We were delayed getting into our gate. The connection time was short and they make you go through security again which was slow.

The crew was great, the food was great, the seats were torture. I just could not get comfortable. Too narrow, too close to the seat in front. I felt guilty about reclining my seat and resisted but the people in front of me did not feel the same way. I thought both coming and going that the discomfort would conceivably be enough to prevent me from going abroad in the future. Will it? I'm not sure - but it will definitely be a factor in my choice of travel.

Food was pretty good and crew did ok. Boarding was a disaster. Seats and leg room were not conducive to a comfortable flight, especially if you are 6’3” and have the person in front of you leaning their chair all the way back for 9 hours and your are told they are allowed to do that.
