Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

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

The service was great. However the lounge only gets passing grade

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Cabin crew were excellent, very proffesional, polite and friendly, in flight snack was underwhelming, a packet of cheese biscuits, im sure KLM could run to a sandwich!

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.

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

The food could be better. Toilets were smelly all along

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Took a long time for boarding. The flight was comfortable.

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

The seat was like there is no leg space....there were no proper option for food in the airline. It seemed like the airline was at brink of bankruptcy. The crew was helpful except for a few.

Needs better seat for business class. My seat was falling apart. Also no WiFi on that flight

The flight was delayed which cause me to miss my connecting flight in AbuDhsbi airport.

I paid extra for our seats on the way coming back from Stockholm to New York the seats were changed and it was totally waved. This happened to three more passengers.

Online check in of SAS is very poor. Even the kiosks at London had system problems. Either it would print boarding tickets or luggage tags. Many other customers had problems . SAS staff was good and helped.

The seats were really close together and hard to get comfortable. The food was okay. The cheese was amazing! I loved the cold towels they gave us.

The Recaro seats are stiff and have minimal padding. Quite uncomfortable for a 5.5 hour flight. The upfront seats and space are identical to the ones in the back. The upgrade was not worth it.

The seats have no legroom. I was bruised on my knees for having them pressed up against the seat in front of me. Then I got food poisoning from the special meal I ordered. Pretty horrible all around.

Airline left me stranded in the U.S. gave me an unrequested refund of 40% of booking and canceled my trip back! When I asked why, the said “we don’t have to tell you why”. “But you can rebook”. Never again! Paid 2x and rebooked on Austrian. What a joke!

Painful seats for a 10 hour flight. There’s a very hard flat board in the seat that goes up to half the back and after 7 hours it gets impossible to find the right position to avoid the pain.

I loved it the staff across the terminal process from entry to airport and boarding of flight excellent. Onboard aircraft the flight attendants crew were fabooois lovely and always assisting

Food could have been better. My pasta was microwaved into a solid block. Inedible.

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!

Food no variations only beef of chicken no veggie meals

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Pillow and blanket are dirty. My son got multiple bites during the flight

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.

China eastern was fantastic. I had read so many bad reviews that had made me nervous. However, I found that the flight attendant’s, and customer service check in etc. etc. was excellent. I had no problems. I would fly with them again!

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

The crew were excellent, service amazing, blankets and pillow good, cabin temperature perfect, the flight on time, food was unusual selection however plentiful, price for tickets unbeatable through Kayak. Older aeroplanes used by China Eastern was the only down side.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

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.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

We had almost a 6 hr delay, primarily due to weather, the e problem was that they communicated this delay and its length very poorly. The boarding was chaotic - even though they had hours to figure it out! The plane was an old 747 whose touch screens barely worked and there was a faulty USB port under my seat rest (something that wasn't labeled as being there) They organized my delayed luggage well. And I could get updates on the Lufthansa website. My shirt connecting flight charged for everything except water. Coffee was over 3€

Flight was great only departure was delayed to saome ground crew issues

Great experience. Flight was on time and reached destination on time

Nice people, efficient and professional, high quality, and well-run. Everything you want in a flight!

Food is delicious I’ve tried Thai green chicken curry and it was perfect!

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.
