Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

Much better, not their fault but my plane was so delayed causing me to have to take this airline rather than my earlier connecting flight

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.

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.

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

Good friendly service and food - The seats in business class are old, too hard and not very comfortable.

Boarding the plane outside in the rain was a pain. Very safe flight

A Lufthansa flight operated by SAS with a jettime plane. Fight was nice, no food but free tea and coffee.

I child in Buisness cried almost the entire flight. And I had a conference to attend but couldn’t sleep because of that, which was the main reason for getting a Buisness ticket. Also the food is not as good as before. The sheets underneath is also not there anymore. The staff was nice.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

We were delayed an hour leaving Munich (No fault of the crew). They kept us posted on the status so we knew what was going on, but as a result we missed our connection in Chicago and the communication on connecting flights was pretty poor as we disembarked. It was already stressful and some of that could have been reduced by better communications about where to find transfers, etc.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

The plane was old and in new of a cleaning up and renovating on the interior. Seats and carpets were very worn and dirty looking. Cushioning on the seats was broken down and not as comfortable as newer jet seats. Food was a little below average but okay. Staff were friendly and hard working but did not pick up debris or food they spilled when collecting from the customers. But they were very helpful and professional.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Our flight to Chicago O'Hare was delayed an hour, causing us to miss our connection to MSP and spend an extra 3 hours at O'Hare so we could board a plane with a damaged door and wait another 45 minutes or so. The crew was great, the food decent, The drinks were great: 2 glasses of a nice South African Shiraz, an ice cold can of Beck's Beer, and Dewar's White Label on the rocks.

A350 has great entertainment. Make sure to watch the plane's external tail and nose camera's on landing and take off. Seats were a little hard for a 10 hour flight. I am gluten intolerant, they had good alternative meals for me on the flight.

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

Need more time for connecting flights in Munich Food seems worse now on Lufthansa Very uncomfortable seats

Better flight than mum to Frankfurt. But food was very mediocre.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
