Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

Cramped seats. Audio jack for the in -flight entertainment was broken.

Flight was great albeit the long line before the int’l immigration given the timing of the year.

They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

The food service was absolutely rubbish. Very arrogant crew. Does Scandinavian airlines think everyone eats meat??? I paid for my flight but could not eat anything because I am vegetarian!!! I was hungry for 7 hours . I demand for refund! This is absolutely unacceptable!!!! If you want more customers keep an open mind!!! Cater to all meal needs. I have flown many airlines and I never make a special request online never! They always have vegetarian options. SAS has no idea of customer service. Shitty service

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.

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

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

Passengers need to be consistently told by the stewardesses to position their seats up from recline when eating. This is not something passengers should have to request. Common courtesy...

No land services during boarding, specially while moving from terminal to another

Even the carry-ons were not allowed and upon getting down, we had the wait for the longest time for the baggage to put on the jet aisle. We had a short connection which British Airways kept changing and made out entire experience poor. I would never fly BA again.

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

The seats are incredibly uncomfortable. My luggage didn't make it on the flight from London to Nashville.

The plane itself is old and way overcrowded. The crew do a great job of trying to mitigate. It is just uncomfortable for over 8 hours, bearable, but barely. Boarding, and the baggage game, is ludicrous. Why charge extra to check bags when there is not enough room for everyone to "carry-on" and checking is needed? I do not think these issues would be different with other airlines, I believe it is the attitude that squeezes every penny out of each traveler.

Expected a lot better service paying for a business class seat. Seemed to be short on staff and did not get the service I expected.

I flew Club World and was SHOCKED at how totally absent the crew were for the duration of the flight. So much so that we received no drink service other than the post-departure cocktail and that was it. Wasn't even offered tea/coffee and the in-flight attention was so bad that literally minutes before landing the one crew member for our row was scrambling to pick up left-behind water bottles, glassware, trash. And the rest of the crew had already stowed all carts, he was cramming the trash into the lavatory trash can and was stashing the glassware frantically in the galley as we were on final approach. He was so scrambled he left two overhead lockers wide open (that he'd opened) for landing. Unbelievable!

The flight was several times changed. That was inconvenient, to sah the least.

They lost my special meal request and tried to tell me I didn't request it. I had the proof. Then they tried to get me to eat food I can't eat. No apologies

British airways keeps canceling our flights. I won’t be booking any future flights with them
