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.

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

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

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

My American Airlines flight was deleted and you guys never let me know

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.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through 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

The staff were wonderful but the seats weren't very comfortable for a bigger guy like me.

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!

This flight was a dreamliner so I think the space was ok for the legs, but the option for food was again limited and the crew was same.

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.

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

The seat 7A had no padding. I needed to sit on the provided pillow.

Unbelievable food and service! Chefs are amazing onboard. WiFi spotty

It was my first time flying with Turkish Airlines, but I found the staff—from the airport to the cabin crew—to be somewhat dismissive and overly direct. This experience left me feeling discouraged about even considering a visit to Turkey in the future.

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Vegan food tasted good. Restroom could be kept cleaner. Seat tray table was a bit tilted so food tray kept sliding down a bit. Flight crew can be a little more friendly, caring and approachable. Their faces lacked smiles and tone was stern.

The flight was delayed so connection was missed. In Istanbul we were taken to a hotel and no one in the hotel knew so we had to wait hours in the lobby of the hotel while the airline and hotel coordinated. The airline staff is rude at times

The seats have to be one of the worst when it comes to comfort and you have to scramble around to out your handbag in the overhead. The food is still awful. Definitely will not travel on Turkish again and wouldn’t recommend it to anyone for sure.

Business class: Like: food selection presentation Staff on the airline Love: lounge in Istanbul Needs major improvement: attitude of reception at Istanbul lounge: 4 of them sitting there: inattentive and then rude. They do not fit with rest of Turkish hospitality!

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

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

Flight ride was good, crew members were great however they need to hire some better food caterer.

Very good. I thought the choice of Mediterranean food such as falafel for lunch was very thoughtful considering we were flying to Cairo.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?

Everything was fine except the landing. We were off loaded on the tarmac. Squished on busses then driven around for 20 minutes. Dropped at terminal B and needed to be at A so had to wait 20 min in another line to catch a bus then another 20 min wait in customs! How on earth were we to get to our connecting flights!? Not a great first trip with your airline or start of my vacation. The woman on the tarmac was rude too

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Upgraded to business class and it was worth every dollar! The connection in Denver was way too tight time wise and going through customs there plus re-visiting security screen again caused me to miss my connecting flight. KAYAK should not allow that tight of connection on international flights.

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

No assistance as requested. Very late take off. Very hard landing And again , no assistance after landing
