flight attendant spilled juice on me entertainment was limited i wanted to upgrade but $$$ was exorbitant i purchased $69 seat, only to find out day of flight/purchase never went through & I was "assigned" a terrible seat! ( btw another passenger complained of the same thing happening to her)

3 Flights were late, 1 on time. When you have connections you have to run thru the airport because there is not much time. When asked the flight attendant if they could let us out first because we were 30 minutes late she said it's a small airport, don't worry. That seemed to be the standard line. Other airlines are much more helpful. Our special meals were on our flight going from Boston to Copenhagen, They did not have them for the return even though we had put in for it.

SAS is the representation of the Scandinavian minimalism, which I like. I wished they had a more relaxed policy on free water distribution beyond one bottle (500 ml) per person and two drinks, including water, per overseas flight.

Bathrooms weren’t too clean. Onboard entertainment was light. Other than that everything was great. Food, service, comfort and crew. Although it was hard to understand the crew announcements.

My return flight has been changed to JFK from EWR without any notice or reason

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

They lost my luggage. Tromso in winter without warm clothes is not fun.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

I couldn’t make it to the airport for my original flight due to bad weather; roads were shut down, buses and trains were closed. Since the plane wasn’t cancelled, I still had to pay $720 to change my ticket.

They have trouble to keep their flights in schedule. Seems not having enough staff to provide appropriate customer service. Lacking real agents on site to help customers. Have to use QR code/web site/call to be able to talk to real person can help you - and you may have to punch though series of options first, then hold until someone assist you. Similar for baggage claim, no real agent onsite helping if you missing luggage, not like other airline next to UA desk having staff there even after midnight to assist customers.

Everything was great except for one thing. I was sitting in seat 1L with plenty of windows. Because we couldn’t sit next to each other, my husband was in 2L with only one window that he had to almost turnhis neck around to look out. Therefore, the window position with 1/2 of the “window” seats in business class is not optimal

I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

I really do not like the basic in basic economy.

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

It was cold the whole flight. Luckily had Ski-Jacket with hoodie. The food was just boiled macaroni in 'ketchup'. Better bring your own BigMac. Assisted Boarding was SUPERB!

Great hospitality and service! Seats are better cushioned then some

United delayed the flight to assist customers to make the connection. The Ohara customs area was overwhelm which created an issue for customers trying to make the Little Rock connection. The delayed allow several customers to make the final flight into Little Rock.

The trip was good except for the delay that caused a connection issue in Chicago.

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

The flight was wondering, especially the special assistance from airplane to airplane!

They canceled our flight last minute and we had to get another flight with twice the cost

Captain waited 45 minutes for late passengers boarding from Washington DC to Munich which was nice for them but caused our luggage to miss boarding our connection on to Bucharest. We then did not receive our luggage for about 48 hours after landing which was very inconvenient for our travel.

The worst experience of my life and I have been flying for 33 years

We were very upset when we checked in for our flight to be charged 208,00 euro for luggage fees when the site clearly states we are authorized one checked bag each and one carry-on. We have never experienced anything like this with Lufthansa and are very disappointed. We should be reimbursed this erroneous charge. I can forward all receipts once I am able to scan the them.

Poor, we had 1 hour to grab our checked luggage, go through customs, recheck bags and run across terminals to make our United flight. Poorly planned connections.

Check in in Albuquerque was awful. The people were great but they were over loaded. The procedures were terrible. We got through fine but it took 90+ minutes.

Every host and pilot were very professional. My next flight would be upgraded from economy to the next group.

I asked for a window seat and when I got on the plane 24A did not have a window so was very not happy, but good and entertainment was good and the staff was very good, so the only complaint was the seating.

Flights were actually with Aer Lingus outward and American Airlines & Aer Lingus on the return journey. Outward flight with Aer Lingus was good but the return flight with them was not so good as our seats were in a poor condition (15A & 15C) and looked like they needed replacing! The American Airlines flight from Miami to JFK New York was good and the seats were very comfortable and spacious (32D & 32E)

Awful. Flight delayed and we missed our long flight to Rome. It has been a nightmare and we have still not arrived. It was NOT a weather delay, just poor planning by AA

My seat was in a good row. In our section it was the first row. But it was difficult tooperate seat entertainment features > table, screen, even though I often fly.

Boarding was as fast and efficient as possible. The flight crew were amazing and extremely friendly. We enjoyed our flight.

There was nothing to like besides the crew. The comfort of the airplane was poor (seat did not work properly and it was not comfortable). The “entertainment” system did not work! On a flight that last nearly eight hours, (which is advertised as having excellent entertainment options), that is unacceptable! Passengers should have been given free WiFi for the flight. The food served on the flight was below school lunch grade food. (With one exception, the ice cream snack). The chicken entree was tough and nearly impossible to cut and eat. The “pizza” served later in the flight was worse. The chicken pizza had a dry crust and the “toppings” were equally not enjoyable. The amount of chicken and cheese were almost non existent. Overall not a flight we would want to repeat!!

There was a problem in the luggage because there were not porters

2-1/2 hours on tarmac after arrival to DFW, lost connection to London, 3 hours wait for customer assistance, stayed on our own account in DFW, no replacement flight for 5 days, had to cancel the entire travel and return to Monterrey today.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.
