Cons: "CONSTANT ANXIETY!! Our flight to Chicago was delayed. By 2 hours. This normally is not a big deal but it caused us to miss our connecting flight from Munich to Bremen. Then our new flight with a later time to Bremen was cancelled 20 minutes prior to boarding with no more flights to this area. The service center helped us redirect another flight to Hamburg, Germany. We had to fly to Vienna and then to Hamburg. We made it to Vienna after a 40 minute delay however, this delay caused us to miss our connecting flight once again. We were placed on an early flight the next morning to Hamburg which was an easy flight. When we got to luggage in Hamburg we noticed our luggage was missing. Supposably still in Munich. We then missed this flight and missed out on valuable time with friends who live in Germany."

Pros: "The crew was very nice. The hot towelettes before eating was very nice."
Cons: "Squished in the middle of a row. Unable to get up and get things out of my bag. Video screen not working. I had been looking forward to catching up on some movies ( rarely have time for to or movies usually) was disappointed to have no working screen on such a long flight. Did appreciate the effort to supply a gluten free meal, unfortunately someone added whole wheat crackers ( luckily still in wrapper ). The boarding area was mixed with people trying to get to New Jersey at the next gate making it very crowded and confusing, people found themselves in the wrong line."

Pros: "The attendant who did help was fantastic! The ride was smooth."
Cons: "My 12 year-old had a screen that was not working and finally we got an attendant to help us out. But until then, I had attendants who were telling us to try things and then they'd leave and not come back to check up and follow through, which left us constantly trying to find someone...one time our call light was on for 20 minutes before anyone attended to us. In addition, the bathrooms were very dirty. The breakfast was a really bad muffin that I couldn't eat."
Pros: "Overall, United in US gets a two rating. International flights get a four rating."
Pros: "Lots of movies."
Cons: "The back of the plane was significantly warmer than the rest of the plane. Very little leg room."
Cons: "More room. Not losing our luggage at the end."
Cons: "On the Copenhagen-Milan leg, since I was in the cheap seats, even water cost; $3 for a bottle of water. They couldn't even offer a cup of water for free? False economy. And I was told that I had to pay for my luggage at the airport, then it was $120 for 1 bag. Ridiculous!"
Pros: "Excellent and professional crew members"
Cons: "Nothing, the flight was smooth, most enjoyable"
Pros: "Clean and very good stewardesses"
Pros: "On time travel. Check In Staff were kind and engaging."
Cons: "On flight staff were minimally attentive. Food was mediocre."
Cons: "The food offering"
Cons: "Flight to Stockholm was cancelled. SAS Provided no informaton on the steps for re-scheduling my flight. I had to call the SAS headquarters in Stockholm before receiving any guidance on what to do next. All service attendants ditched the ticketing desk leaving one poor employee to answer questions for over 70 disgruntled passengers. Very very very poor communication. Luckily I was finally able to book a flight using another airline after waiting on hold for 20 minutes with the regional customer service provider."
Pros: "The staff and other guests are always so polite! Getting the SAS Lounge Pass is always smart."
Pros: "People were very kind. The food was terrific!"
Cons: "The entertainment system was slow."
Pros: "Aisle seat"
Cons: "Nothing was complimentary"
Pros: "Very comfortable and smooth flight, on board entertainment on first leg of trip was great. Food was fresh and good. Nice coffee & Tea service,"
Cons: "Boarding was a little scattered, but ok"
Pros: "Easy boarding. Friendly staff"
Pros: "One crew member was particularly nice and personable."
Cons: "We waited an hour in the plane before take-off and after boarding, during which time the crew deliberately filled the cabin icecold air thick with the highly toxic fumes from the deicing. I got a headache from it. Throughout the process the entertainment units were disabled, when they could have helped distract passengers from this ordeal. The food was disgusting. When the Danish government has repatedly bailed out SAS, it would make a lot more sense for everyone involved to have higher quality Danish products on board for the meals, especially for such things as dairy products."
Pros: "On time, easy boarding"
Cons: "The flight was nearly full and everyone seemed to have at least two cases. This caused lots of jostling for space in the lockers"
Pros: "Pleasant crew"
Cons: "Boarding was shambolic and the 737 is not as nice as the new A320 in terms of comfort or amenity. Boarding was all over the place - and the gate agents clearly need extra people around for a full flight. One person for 170 ppl didn't feel right."
Pros: "All went well !! On time friendly staff ."
Cons: "They only offered tea and coffee for free as a drink and nothing anything more, and were not kind at explaining this."
Pros: "Crew were excellent, had a row to myself, luggage turned up quickly"
Cons: "No landing cards given!"
Cons: "Food was really, really bad. Only one very bad choice ignoring health conditions of different passengers."
Pros: "The flight attendants were very nice and on the cross continent part of our flight we had dinner and breakfast served. Lots of leg room."
Pros: "They gave us blankets and pillows. Each seat had its own entertainment system but it only worked with the earbuds given out by the crew and the controls were cumbersome to use."
Cons: "The plane was hot and stuffy the entire trip. There are no longer individual controls for air. It was so uncomfortable and we were hot a sweaty the whole flight. The crew said that there was nothing they could do about it."
Cons: "Water and beer paying"
Pros: "boarding is different and they were talking over pa announcements at heathrow so you could not hear what to do. you go through one ticket agent to the down stairs to another ticket agent. everyone knowing what to expect crowded around the second ticket agent and there because of that forget about boarding by row or zone you couldn't get throught the crowd. plus the second ticket agent was right next to the downstairs escalator so people coming late got on before us."
Pros: "The food was very good surprisingly"
Cons: "Again the seats are too tight and they should not be allowed to recline"
Pros: "Upgraded 2 biz 4 reasonable $, everything great"
Pros: "Everything was great"
Cons: "Nothing to mention"
Pros: "Comfortable flight, friendly crew. Would fly again!"
Cons: "Food could have been better"
Cons: "I did not like my flight because ... I could not take it! I needed to change only one date (return) and was quoted $1300 for that one change. Getting a completely new ticket was cheaper, but not cheap. With such cost of even minor changes, next time I will look into booking directly with airlines, instead of Kayak; sorry to say that, as I really liked using your service."
Pros: "Nothing at all"
Cons: "Fight was canceled and no email or communication was possible with this company. Called SAS office - CLOSED. Stood in line for 2 hours and no one came or announced anything. Checkin agents were on dope-no help and checking machines not working!"
Cons: "Out of all the staff on board they did not give me and a few others those blue customs form, so we made a huge line and when we got to the agent he told us we had to go all the way around fill one out and then come back. The attendants new that those were necessary why so many yet not one made sure we got them lousy service. I wish we got a crew that wasnt so insecure and cared more about providing a good service instead of caring so much over their appearance. I rather have good efficient staff what they look like doesnt matter to me."
Pros: "Excellent meal and very friendly staff."
Cons: "The cabin temperature seemed pretty warm."
Pros: "Comfy and good movies!"
Cons: "Not even one bag was included!! And to add a bag is extremely expensive!!! Paid five hundred dkk for one bag!!! Terrible service as well!!!"
Cons: "Not enough room to work on laptop."
Pros: "12 people got bumped!"
Pros: "Easy embarkation, helpful staff."
Cons: "Shock to discover that suitcases were not included in price of tickets purchased online. We had to pay the equivalent of $100 (australian) per case. My seat was extremely u comfortable as the cusihion was misshapen. The male passengers seated behind us were drinking alcohol and became loud and garrulous, making the trip most uncomfortable and unpleasant."
Pros: "Flight was Ok"
Cons: "Left till last to board flight. Case taken from me. Asked continually when I wld be taken as I am 83 and recovering from major operation. Told 45 minutes before flight but was taken 10 minutes ahead. Rush has left me very upset."
Pros: "Wonderful service! Flight attendants kind and thoughtful. Once in terminal 5 (from terminal 1) a Sas gate agent escorted us to flight since our previous United flight was so late"
Pros: "The flight crew (flight attendants are the best I've encountered in terms of tone and hospitality) cleanliness, the food, frequent offers of water, your own TV and numerous options for entertainment and ability to track flight"
Cons: "Like the sleek style but still wish there was a little more leg room"
Cons: "Miserable cramped seating ."
Cons: "1st class could not board because that area was not cleaned"
Cons: "I asked for water and was given half a cup, when I requested they fill the cup they said if I wanted more I had to buy it. In addition, when we left the plane everyone pushed their way off instead of following the order of the rows."
Cons: "Disorganization and unpreparedness."
Pros: "Flight was fine, cr"
Pros: "Same as above"
Cons: "Same as above"
Cons: "Charging for second beverage. Losing our bag and not getting it to us for the duration of our travels, despite repeated promises to do so."
Pros: "Free upgrade to SAS Plus, what's not to like!"
Pros: "The Plus Seating was really good"
Pros: "Lucky is the passenger to get onboard a new SAS plane! Cleanliness aside. The built in phone chargers to the tele is genius. Nice to land fully charged!"
Cons: "I didn't like that they interrupted programming to announce they were walking on board shopping through the cabins. They did this twice! Really unnecessary!"
