The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The food from Lagos to Amsterdam was was very poor compared to AMS-YYZ

The flight was delayed for 2 hrs. Because they didn’t have a crew to fly. And it is not a first time for klm to do that. Last time they cancelled my filght and rebooked me 3 days later. Not reliable airline

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

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

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 .

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

I requested wheel chair assistance , it was confirmed via email that inwoood get it but I didn’t get it . The last leg of my trip to Nigeria was the worst.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

I got denied boarding bevause they said they "ran out of seats on a plane"

Due to long security check and no last call announcements from Gate staff, my family and 12 other passengers missed the flight.

very delayed boarding; the crew started the service extremely late and everything felt like they didn't want to be there and do their jobs; the pilot changed her mind about landing :))))))))) and we spent 10 more minutes circling around the airport before landing, eventually!!! lack of communication = lack of professionalism. she could have said 'ladies and gentlemen, due to us having taken off very late, we have lost our landing permissions and we'll have to wait some more', but she chose to shut up. big mistake that reflects poorly on the airline and herself.

Θα ήταν καλύτερα να προσφέρουν ένα μπουκάλι νερό δωρεάν και καφέ .

Ryanair is the worst airline in Europe and easily one of the worst in the planet

O voo atrasou um bom bocado A tripulação não era comunicativa,não fez vendas... Não abordava os passageiros... A 1°vez que me acontece tal coisa 🤷‍♀️

While this flight from Dublin to Venice boarded on time, its departure was delayed by about an hour because, apparently, there were no demonstration kits on board, and we couldn't depart until the safety demonstration was completed. We were informed that we were in danger of losing our delayed slot if Ryanair engineering didn't provide the kits 'soon', which would have resulted in an additional two-hour delay. Thankfully, we didn't incur that additional delay. It's not clear where the source of this problem lies but it needs to be addressed to ensure it does not recur for other flights in the future.

Usual RyanAir flight but disembarking was poor, no rear steps. The Faro Airport required lots of up step and down steps, no elevator Getting through passport control took 50 minutes in the EU line

Flight was delayed due to weather so not much Ryanair could do about that - otherwise it was very efficient and smooth

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

All was good. The headphones they supply are of poor quality. The food is good but too much dairy.

Everything was great except for online checkin. That was through BA- glitchy and needed help on seat choice in person at the airport (and the staff were fantastic). Unclear if the problem is due to booking lower fare thru kayak vs directly with Finnair or BA but seems to be the norm.

Staff , Comfort and Food were excellent. My individual lamp did not work so I could not read, neither my novel nor the menu.

No food as per my diet restrictions even after advance request and delayed baggage without any notifications

Positive boarding experience, easy access to seat with plenty of luggage space

This flight had seats that were more comfortable than the trans-Atlantic flight I had come on. Boarding, however, was atrocious. There was no point in boarding groups since everyone ended up on the same bus to get on the plane. And the bus ride took forever to get to the plane. The snacks can barely even qualify as snacks. Make sure you bring your own or eat before getting on,

Taking off and landing was so smooth. I like the food too. Served 3 meals on both flights. I have been telling my friends to take British airways

It was good but it got bad when they cancelled my flight to rochester and couldn’t get me in any flight even for the next day they said i will be a standby.

My flight got cancelled and it was a very bad experience

The crew is excellent. However there are a few things that are not satisfactory: seats are smaller than many other airlines in economy, food was sad and I had bad diarrhea after I drank a cup of tea, They also forgot mine and many other people’s luggages somewhere this time. The luggage was delivered two days later, which caused a big inconvenience because 1. Most of my son’s clothing are there and he had to go back to College before the luggage was delivered. Now I will have to mail his stuff to him; 2. Two pairs of shoes are missing from the luggage.
