The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

The flight was again delayed for more then 2 hours with some lousy explanation regarding the reason of the delay. Although the flight was delayed for more than 2 hours, no refreshments were offered (according to EU regulations). Last 4 flights on KLM - always at least 2 hrs late. So be prepared that you cannot plan anything with KLM.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

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.

no issues at all... Kudos to the food. This time was really really good

The food was ok. The crew seemed like they were cranky. I had one guy get mad at me for passing in between the storage area to get to the other toilet. I can understand if it's not allowed but reprimanding me like I'm a student saying "This is the last time!" was not appropriate. During my meal time, there was a French family around me. No problems there but when we usually have meals, they are supposed to put their chair in the upright position. These people did not do it and the steward did not tell them to raise their seat in the upright position. However, I was told to do so! So, me and another person next to me had to eat with the monitor almost touching our faces. Furthermore, a lady in front of me was putting her feet up and preventing another elder passenger from putting her seat back. To make it worse, she was continuously hitting her back into her seat, shaking my monitor while I was watching a movie. A crew member did speak to her about it but then she accused me of pushing her seat forward! The crew member gave me a death stare and told me to stop pushing the seat forward. I did not even touch her seat at all, if I did, she would know it. Her boyfriend also stood up and tried to push her seat even further past the maximum decline to no avail. None of these people were reprimanded but the steward, some bald guy, was extremely friendly with them and did not even try to instruct them to do anything until it was time to land. I resisted the urge to really argue with them because I would have obviously been seen as the aggressor (I have no idea why). I hardly said anything on this flight except "more wine please" and "sorry" if I bumped into someone accidentally. Overall, it was an annoying flight and I had to resist the urge to yell at the steward and the people he was overly friendly with. The happiest moment of this flight was leaving it.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

Mostly fine. Minor delays departing and arriving. Quite a cramped plane, not so much as regards legroom but very narrow seats. Quiet nice food. Non-working USB charger. Flight attendants were helpful but not particularly proactive — one had to work to get their attention (but all was fine once they notice you), very Dutch style:)

I travel frequently. The flight was late again... KLM should really try and be on time

All and all pretty good. It’s crowded but that is what flying is all about. But no complaints otherwise.

Well, in my case; the flight was delayed 1 hour, we have to wait in the plane to get green light. And the plane (probably because was a short trip) did not have entertainment or WiFi. No a good experience.

Not impressed. Only allowed one carry on on such a long flight.

Wore experience due to delay and took me 3 days to reach my destination.

They have misplaced my one checked bag which I have not received in Philadelphia and have lodged complaint with American Airlines, the staff of Indigo was rude with us, at the checking counter, I think she purposely withheld my one of the checked bag, because the American Airlines staff told me that bag was not received at Doha airport. Kindly help me with one of my checked bag to get it. My flight was from Mumbai to Doha and then Doha to Philadelphia.

I liked the overall service and comfort. The only annoying thing was paying for excess baggage at the airport. They have limited options and they don't take all cards.

Other than low space, which is the problem with all airlines for economy class, the flight was excellent.

Okay not so good or great. The flight operated by Indigo is worst from boarding to luggage handling and food. Damaged one luggage and delayed another luggage. Still did not get it, since 2 days.

I would advice everybody not to fly by Indigo, no entertainment in flight, rude behavior of staff, worst experience of my life

The staffs were very good and helpful especially since we were traveling with a toddler

In spite of placing requests for vegetarian food, I didn’t get it because they ran out of stock. According to crew, only fixed number of vegetarian orders will be carried. Typically, they should have checked and served those who had specifically requested. I was one of those to get the food last.

Ordinary Indian food... Not great. Limited movie and TV selection

Old cabine without flat bed in business for a 12 hour flight is not acceptable

Generally good. The crew is excellent. The food could be better.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

Lost luggage, 2 bags were badly damaged and one of the bags came open.

The line at boarding was not well organized and managed

Je n'ai pas pû incliner mon siège et une des hôtesses ne comprenait pas ce que je disais. Je devais parler fort

their gluten free lactose meal is the best, I have never been satisfied with my flight meals. I definitely enjoyed my flight and the chair is very spacious for economy. I'm so glad Delta is my flight way back to NY.

The crew was great and handled our unexpected detour with proactive communication.

Flight was more then 3 hour late and I did not get my luggages

The hard product, food, and service are far superior to their North American counterparts

1st of all on February 27th Abu Dhabi to Delhi flight the seat wasn't comfortable at all, coming back the Lounge at Abu Dhabi didn't have anything. Than the Food in the flight

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

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.

One thing is very important is you people not giving seat arrangement together to couple, senior citizen. You have to take care of senior citizen. Do not look about money. Money is not important everywhere. Make relationship strong is very very important. I like Etiyad air line out of all air line. Food was hot and delicious. Air hostess gave very good service, nice attitude, very good behaviour. I gave 10 out of 10 marks. Thanks Jivraj

1.Aircraft Comfort: The aircraft type was quite small with non-reclining, cramped seats that significantly lacked comfort. 2.In-flight Entertainment: There was no provision of in-flight entertainment screens or Wi-Fi for the majority of the flight. 3.Boarding Process at New Abu Dhabi Airport: Despite the move to a new airport, which promised enhanced experiences, the use of buses instead of jet bridges did not meet expectations, causing inconvenience. 4.Gate Change Communication: A last-minute gate change was poorly communicated, resulting in a long and difficult walk.

Food was very good. Again tray could use a non-skid mat. I had a regular seat - comfortable - able to sleep undisturbed. Boarding was uneventful.

Sits are very uncomfortable Don’t feel like to travel in Etihad. It was 1st time we traveled in Etihad now we decided we don’t want to travel in Etihad.

Very very bad service very tight seats never ever flying with Etihad again

The flight was small and was not cool very bad

Short travel duration. However, I had placed meal preference while booking my air ticket but was given vegetarian meal on board. Food was okay. Not so great. Didn't like Spanish eggplant, cold chickpeas salad. No hot soup was available. Everything cold cold only.

We were helped whenever needed and had a pleasant flight.

Checking in for ongoing flight from Singapore could not be done in the UK. This meant we were not sure whether we had seats together or in the right place. This needs sorting!!

Horrible crowding on the seats, headphones provided did not fit or work in the entertainment center, seriously the most uncomfortable flight I have taken in a LONG time. The people in front of me were literally 5 inches from my face the entire flight. Did they change their seats recently? I remember it being tight but wow this was a whole new level. Also I am a 5'3" small woman so I can't even imagine a larger person dealing with that for 11 hrs.

Just lucky: After realizing I was on "standby" b/c of a technical seat problem, someone volunteered to go Premium Economy, & I got to keep my Business seat. Found broken headphones, and they replaced them immediately! Excellent food and beverage service. Although we went to ALM first on our way to NQZ, it meant Business class was almost empty for the last 1.5 hours of flight- heavenly!

It never happened. The flight was canceled because of ground crew strikes in Germany.

Boarding is as always an issue. Slow and long boarding time.

Great except my luggage was. Lost my entire. Trip and I had. To go buy things and waste. Time trying to find. My luggage

I always like to travel with Discover Airlines because of their extraordinary services, comfort, and feel safe.

Lufthansa lost our luggage. After a lot of chasing on our part we got it back. The main problem is that there was no office in Bogota to help us outside of flighttimes. The customer service phone lines had no data on our luggage. I think Lufthansa need to invest in managing communications over lost luggage or this will end with everyone taking more luggage out of hold.

Flight was delayed and caused us to miss connection in IAD. Then bags didn’t arrive at bag claim until 1.25 hours after flight landed.
