The required privilege for business class while boarding is not given. Food is average. The seats in business class are bad, worn out and dirty

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

My flight was delayed by 6 hours then I missed BOTH of my connecting flights, I then had to stay in the AIRPORT at JFK because soooooo many people also suffered from missing flights and there was no hotels available. I would like to be compensated for this experience! I had to stay in the airport for over 16 hours!

Klm start boarding while somw air issue in the plan

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

The flight was great, the only reason for middle scores on entertainment and food is that it was a short flight so not included (but snacks were served including alcoholic beverages free of charge). I would definitely recommend KLM.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

The Crew have no idea about the food they're serving the passengers. The Crew MUST be instructed before each flight about the menu that will be served to the passengers, whether the food is vegetarian or non-vegetarian, whether it is Halal, Kosher or not.

Flight attendants were attentive and friendly. Enjoyed the peppered shrimp snack. Check in was easy. Only negative was the time it took to get checked luggage, but that was the slowness of CPH staff.

Better food; taste, portion. Bottle of water per seat was great.

Excellent business class seats, service and food. No airline does it better.

Great logistics and timeliness as we arrived quite early. Flight smooth and fast. Excellent entertainment. Plane itself was a bit tired and the crew mostly indifferent. Baggage took forever but that’s on CPH. Would use SAS again for sure.

SAS has too many other airliners. They don't need to exist.

OK experience except for the fact that I had to pay $100 for one checked in bag in Amsterdam, while it was supposed to be free like it was on the flight from LAX to AMS. I want SAS to reimburse me for this!

You changed our seats without letting us know. We booked two seats on the side of the plane including an aisle, but you ended up putting us in between two other people in the middle of the plane. My husband is 6' 6" and I'm 5' 11", so we need an aisle seat. We were able to move thankfully because the flight wasn't full, but I had to ask the stewardess. You also didn't give us a meal for several hours on the return flight, and it wasn't great (toast with olive/cheese). Finally, you lost our checked bags in Copenhagen so we had to wait an hour after we arrived before we realized they weren't coming. We put in a claim so hopefully we'll still get them.

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.

On this shorter leg and with an older plane, just mediocre. On the connecting long haul (Chicago to Copenhagen) everything was great.

Boarding and crew were excellent. Seat could have been more comfortable (hard on lower back).

Business class ticket should include lounge access and seat selection. The food quality and varieties should be more. It was surpirise that no dessert was offered.

Good one but just notice that you have to ask several time to get water or coffee .

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

One of your male flight attendant was pushy and a bit of a martinette. Completely unnecessary.

Likes: on time departure, new plane Didn’t like:very poor quality food, very limited entertainment.no amenity kit etc.

My wife and I were upgraded to Business Class on our Dublin-Abu-Dhabi flight on the 22nd of January. Being served by "Mariyan" (not too sure about her name, she's from Tunisia) was the real highlight of our flight, she deserves to be working with etihad. We are looking forward to the next upgrade as we are flying back to Dublin on February 01, 2024. If I am not mistaken we have just reached GOLD status as Etihad Guests.

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

The service and courtesy of the flight attendants was good. The check in staff were ok. Seat on the flight uncomfortable.

Transit time could be 15 min longer atleast. It was right on the dot to boarding time. Giving minimal time to do shopping

This was my first time ever flying China Eatern and it will not be my last. I was very satisfied with my whole experience and trip. Thank you very much and until soon.

While boarding at PVG, there was a ticket checking at the gate, then there was another ticket checking at the bottom of the escalator, which created quite a dangerous congestion. Not sure which idiot made this absolutely unnecessary arrangement.

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

China Eastern as a member of Sky Alliance airlines should have the same standards overall of their partners, Besides the seats comforts everything else is bellow the standard for a business class travelers.

Flight was on time. My group paid for seat’s so that us four can be seated next to each other. We all got separated. We all got middle seats, which made it more difficult to be able to get up and stretch or use the restroom. We tried talking to the employees at China Eastern and they were of no help. We will not be taking this flight or recommend this route to others in the future. Also I will be contacting customer service on how I can get our money back for paying for assigned seats.

Excellent experience however older aeroplanes used by China Eastern Airlines.

For the price we paid, I couldn’t complain. Was good value for money. Service was excellent but food was mediocre. Crew were excellent and spoke English. You will never go hungry. The food was ample but was mediocre. Entertainment limited and wifi doesn’t all allow you to access some social media. The best part was comfortable seats and bed (business class) with a screen to close out the rest of the cabin.

Cheapest option from Gatwick £400 cheaper than Emirates and Qatar. Entertainment no where near as good as Emirates and Qatar, but saved £400 so all good.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.

How do you run out of beer after one hour of a twelve hour flight?!

We flew first class - the screens are outdated and very small. Even on highest brightness level is was hard to recognize anything. Food was on average, nothing special. Champagne served was the same other airlines serving in Business Class.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

The aircraft was old, there was no charging sockets, and the seats were narrow and uncomfortable even though I had exit row premium seats.

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.

Great seats assigned and comfortable, movies are good, food is delicious, great experience. No delays and they prioritize boarding children with parents which is plus.

Narrow, uncomfortable seats with metal structures under the seats that made it impossible to sit normally. You had to put your legs in oblique positions, causing pain in your spine and legs. This type of seats should only be allowed on short local flights of up to 2 hours, not on 10-hour intercontinental flights where you can hardly walk and go to the toilet due to lack of space. There is no question of short "walks" enabling circulation, due to lack of space. The plane's staff did not respond to calls and were engaged in long and loud conversations among themselves. They served only at assigned times to deliver meals. The entertainment system was not working properly and was hanging. The headphones didn't work properly either.

Baggie arrived in Athens with l’hiver in Munich on time. They are pros, do it right and on time

The crew was very friendly and attentive. Business class seats were comfortable and the food was good. Positive experience
