It will get you where you want to go. Power did not work on ether of the 2 planes but staff was lovely. Wood like to see a improvement to the food as the amount was small but the main issue is the food isn't tyed to the location your going to the airlines own culture. So that would have been nice. Staff was crazy nice and even helped me with a very tight connection

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

I did not use entertainment on board, so, cannot really evaluate. the flight was fine.

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

Delay, luggage didn’t arrive. Had to go the next day to collect it

Pretty bad. Food was awful. drinks were scarce, as if drinking an extra drink would ruin the airline. attendants were not very helpful. likely Dutch "directedness" (I cannot be bothered). Crammed flight. Entertainment in very minimal dosage. Almost all old movies and series with 1-3 episodes only. Very limited number of options available. Jesus!! it seems you need to bring your own entertainment these days even of flights that are 13 hrs long!! I would and I will avoid in the future!

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.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

The flight itself it was great nice food the crew were very nice and helpful, Checking in from Birmingham wasn't great long queues for bag dropped, And I had my hand luggage case taken away from me even though I requested to have it with me as I had breakables items. I was told I can not because of the length of the flight with no explanation at all no options was given for me to take my fragile items out of my case it was taken away with hold buggage I find the staff member who was checking me in very unpleasant !! Can we please be advise if the rules have changed about the the carry on hand luggage it will be easier to be advise on booking your tickect if we not allowed to take the hand luggage with me. Overall I had a good flight .

Amazing KLM service and brilliant economy comfort seats. Well worth the extra.

We traveled with my 90 year old mother and she was well cared for by everyone from the wheelchair attendant to crew. Greatly appreciated!

Very comfortable flight. Great service, food options, and entertainment options. With Wi-Fi!

On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

Most narrow seat of my life. Easyjet has larger seats. And as I just wrote in the last comment section - Seat 1A promises luxury after a great businessflight. Instead, it's narrow, the seatbelt is 20cm shorter than the one in 1B, it's just a joke.

No snacks, drinks or coffee. No entertainment, not comfortable seats

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

From boarding to disembarking, the whole operation was very efficient.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Flight got delayed and they didn’t keep us informed all the time.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

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.

Lufthansa staff was fantastic, but the airport was a mess. I was at this airport in the past and I have never experienced any problem, but this time it was nutty because of soccer tournament: UEFA 2024 championship

What food? What entertainment? The questionnaire does not make sense.

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.

Staff and crew were very helpful. I wish there was less delays on the flights that made it stressful for the connecting flights.

The transatlantic leg was on Discover Airlines. I’m 6’2” and the extra leg room seat was acceptable, the seat it self was moderately comfortable (slightly softer than a church pew). The food was a standard economy fare. Frankfurt to Prague leg was on Lufthansa the business class was as advertised 10 across the board.

It was only an hour flight, but at that, it was still late
