I was not admitted to the flight!!! i need a refund for this.

It’s my new favourite airline! Everything was smooth and relaxed!

One of the best flights I've been on in a while. Very genuinely friendly staff. Courteous, kind, respectful. On a past flight (not Aer Lingus) I remember being woken up rudely to put my seat forward. Like a child being berated for something. Oddly jarring experience when someone could just tap you gently on the shoulder and gesture kindly. But I noticed the Aer Lingus staff were incredibly patient with everyone on the plane. It's the holiday season and I noticed a lot more elderly customers on the plane than I typically see flying, and the staff went above and beyond with helping accommodate people. Service throughout the flight was flawless. They came through offering water, and picking up garbage at perfect intervals. Seemed like this flight, everyone was on point. And the flight landed early on top of that

Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.

Experience was great overall. However, the connection time between my flights (1hr 15 mins) was too short. We had to get through security check and US immigration in that time, and I made it to the gate just as they were announcing it was about to close. Flights with such a short connection time should maybe not be offered for purchase, or an advance alert would be helpful. Other than that the in-flight experience was excellent, especially the food. Many thanks!

The seats needs to be comfortables, at least please add more padding to the seats.

Incredible service. Incredible entertainment. I felt like they just kept serving us something new avery hour. My wife and I both had a joyous flight.

They out me in the baby row so I was surrounded by toddlers, they also did not send my luggage and was not able to book my connecting flight

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Slow and delayed boarding, including standing outside 15m in -3 temperatures, Late take-off approx 45 mins Very slow bag delivery approx 45 min - no explanation

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

Flying from Newquay was an absolute dream! Would 100% recommend flights from there!

It would have been better if I was not ill so I didn't go and I didn't come back and I could not transfer my tickets to a later date as Ryanair stop flying from Manchester at the end of October till next year

Passengers next to me insisted I change seats so they could sit together. I had to frequently move so that when the sear belt sign was on I was in my proper seat! I was returning from helping my mum with my dad's things after his sudden death and didn't feel like arguing with the other passengers.

Flying from Hamburg to Stansted was a nightmare if I have to be honest, the flight was due to leave at 15:50 and we ended up not taking off properly till 16:56. They really don’t have enough people doing the sorting of baggage where you get the sticker for your case before the security check, going through security was 10x more faster then the whole baggage situation.

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.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

The flight went well. However the leg room in coach class is very very tight. We arrived early but could not get to the gate early….sadly. Also something about off loading cargo- we had to wait to deplane. There was not clear explanation for that.

Awful. Flight was late. Follow flights cancelled. No person at the British airways counter for hotel voucher. Awful service.

Need thicker and wider blankets. Food was below standard especially in the fist leg.

I travelled in business class and was disappointed by lack of service, curt and borderline rude time of the crew and to top it off, all of my luggage was delayed. It was like pulling teeth to even report the missing luggage and recover it the next day from the airport.

Boarding was poor. All groups called immediately one after the other resulting in a long queue in the jetty/jet bridge. Seats were very hard and and did not recline on a 4.5 hour flight. No food was available. Plane was cold. There was no entertainment.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

The update about flights and the terminal changes information was great.

I love FRA - LCY route. So much better compared to the FRA - LHR route and the price differential is ZERO

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

Very late to leave, poor communication on expected departure time and when boarding actually started.

Everything was perfectly fine, it’s exactly what you would hope for from a budget airline. You get what it says on the tin, what more could you ask for?

Cheap flight but I didn't like the almost one hour delay because of paperwork!!!!

Gate is far at Leeds Bradford Airport. However, as the flight was less than half full, it was calm and not stressful. Great take off and landing. Friendly staff

Boarding was started early and we were lined up in. A glass tunnel on the tarmac we were left standing there for an hour with no information the flight left and arrived 30 mins late

It was great. We arrived a few minutes late but the crew were concert and kind about it. It was a nice smooth fly thanks be to Jesus. I prayed for smooth flight and Yahuwah answered my prayer.

Need more check in desks at Marrakech. Even if you are travelling with hand luggage only, you still need to 'check in' to get the old style boarding pass. Unfortunately they haven't thought to separate out the people checking in luggage to a separate desk. Flight was delayed leaving but arrived on time. Limited food options on board and very overpriced.

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Stanton airport is outdated, pure equiped, airport. Fire alarms, power outages is a common routine, wich result ir flights delay , additional money spending and huge gathering of people in airport wich is unsafe.
