Klm start boarding while somw air issue in the plan

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

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!

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

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.

You should not have to pay for WiFi in business class

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

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Etihad seems to have a very strict luggage enforcement. I am a very light passenger compared to other passengers which are mainly heavier. I do not understood why airlines enforce the weight restriction so strictly. I was overweight luggage of 1.5kg, but am probably 10+kg lighter than the average passenger. Other airlines are far more accommodating. Poor customer service as far as I am concerned. If weight is such an important issue to an airline they should charge passengers by total amount of body weight plus luggage. To me just ridiculous.

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.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

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

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 flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

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

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

The crew was fantastic. They were always there when we needed them. No wifi on an 11 hour flight was a bummer. The entertainment onboard was boring.

The plane delay due to a poor judgement of the pilot. It was the only flight that got delay due to fog.

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

Excellent once on board. Security staff at Johannesburg rude and aggressive.

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

I’m glad the bus waited for me to connect me to my next flight since we were delayed. Flight was good.

It would have been nice if my luggage had made it onto my connecting flight as well. Now I have to wait for my luggage to be delivered and that might take a while, which certainly put a damper on the entire experience.

The service was really good. The breakfast food could’ve been better as I don’t eat sweets for breakfast and the only choice was a muffin. Overall, good experience though. Thank you.

Seat cushioning, and having at least 1 checked bag free, I dont understand why international flight would not include a checked bag.

Pretty poor across the board - flight details wrong/delayed into Lufthansa app. Seat changes made without notification. Boarding delayed (ok, that happens) but all comms in German (for flight to UK, where 85% of passengers were English). Outright fraud attempted at gate, denying 1 piece carry-on of smaller than correct size and 1 piece personal item, again, smaller than correct size. Rude gate staff. Security checks perfunctory - unattended bag not acknowledged by staff..then put on aircraft unclaimed by staff.
