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

8.0 ExcellentJacob Oluleke, Apr 2024LOS - AMS

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

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.

Seats are fair enough for medium tall people. Good food all the trip. Fight attendances are warm

One of the vstewardeses wanted to bump me of the plane for absolutely nothing. There is CCTV in the plane ans everything can be verified. Very disappointing , you all will see, o other 5 years and the passangers who does not smile to flight attendent will be bumped off...

The worst airline. Cancelled flight 30 min before boarding and rebooked on flight after 3 days.

It was nice to be on a legacy airline, people try at least.

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 .

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

We missed the flight due to very slow security control and lack of last call announcement. We only found out at the gate that the gate is closed. Altogether 14 or 15 people missed the flight FR4500 from Cologne to Dublin.

Everything went according to plan. Check in, boarding etc all were very efficient.

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

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

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

The flight boarded and departed Venice on time (more or less), the cabin crew were super friendly and efficient, the flight crew kept us informed of progress, and the flight arrived early in Dublin. All in all, this flight was as close to perfect as is possible to achieve. Well done, Ryanair. The fact that Ryanair aircraft arrive and depart from gates that are in the back of beyond in Dublin's Terminal 1 is a bummer - in terms of the length of the walk need on both ends of a return flight. But I suspect that this is not Ryanair's fault

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

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.
