Excellent outbound flight to Arrecife on a new very clean Airbus with great flight crew. Flight was only delayed around 10-15 mins and boarding was very good. Comms from pilots and crew was very welcoming and excellent throughout flight.

Flight was ok with a great landing. What could have been better would have been sitting away from the lady behind me who was coughing and sneezing all through the flight. I have been ill with a very bad cold ever since and can only put it down to being sat in front of that lady!

I liked boarding the crew were excellent but the seats are too close together for such a long flight.

The seats could be better as they’re not very comfortable and the arms would be better padded. Only place we found to fill our water bottles was at the Castle Rock bar who had one small sticker on one pillar saying they would refill your bottles with tap water for free! Need some/more refill stations around the departure area.

Boarding went well, seats could have been a little more comfortable

Great flight from malta airport, all on time & no delays, Birmingham Airport a little confusing with the ongoing upgrades!

The plane was late in so we were late leaving. The plane had been cleaned and was tidy, the staff were welcoming. Our standard seat had good legroom but after an hour or so of sitting, the Seat started to feel uncomfortable. We didn’t have any food so can’t comment on that and there was no entertainment available. We did buy some duty-free goods and the prices are good. We made up the lost time and landed slightly early.

Nice seats with matching colour coded seat belts to make it easy to identify the correct two parts.

We waited about an hour outside the aerport building after boarding by the gate waiting to board the plane. the plane wasnt there yet.... It was freezing, 8 degree Celsius, barely chairs to sit, no staff to ask question, no screen with information.... The plane arrived, after about forty fives minutes wait there, and until it was emptied, passengers, suitcases.... only then we allowed on board. there was there babies, and older people, besides of the rest of the passengers. it took me over an hour to recover from the freeze. It was a disaster. I don't understand how the airport crew decided to do boarding by the gate forty five minutes before the plane landed. would love to hear a reply from you. i will send this message to PAPHOS INTL AIRPORT as well.

Boarding lanes should have been better organised..as it always becomes a free for all..

Very pleasant crew, working hard on a full plane. Delay by a broken seat. However crew made back 60% of the delay.

Delayed and then further delayed with no announcement made so that all the passengers (who were standing in the jetty) could hear. We stood there for well over 20 minutes. We were further delayed through weather but no one explained that to us until the pilot made an announcement when finally on board

easyJet need to ensure that whether pre-booking seats or not children aren’t split from their parents the crew spent the majority of boarding asking passengers to move to accommodate two families. Surely the system identifies minors on a booking !!!!! It was all very frustrating to watch and caused delays which I’m sure cost easyJet more in the long run rather that automatically allocating families with minors seats together automatically.

As you would expect from a budget airline Left and arrived on time, no frills, not even a glass of water offered But you get what you pay for

I had an emergency escape seat. The attendant gave the extrA briefing to my side of the aisle but didnt direct it at all to the other where my wife was sitting

Boarding great. Didn’t eat or drink so can not comment.

3 hours delayed Don’t understand why when you have paid for ‘speedy boarding’ they call you forward to then make you stand fir another 20 minutes in a confined space before boarding the plane.

The pilot did everything possible to make up the 35 minute delay. His communications were honest, prompt and positive throughout.

Delayed and ketone runway. Was told some nonsense about thunderstorms slowing down flights. Why not just come out and tell customers NATO and BRITISH FORCES were doing defence exercises and were in control of AIR SPACE.

Would have liked the plane to leave on time so I didn’t miss connection upon arrival. Some pathetic excuse as to late departure bought about by easyJet incompetence

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.

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.

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

Booked through you used Kiwi who did not complete checking in until 24 hrs before departure when the check in was available 48 hrs before hence we sat separately. I will not be using you again.

Pros: "Quick boarding and arrived early."
Cons: "The seat was very very small for an average size human and the seat belt was on max.. No social distancing between seats"
Pros: "Rate. Didn’t like the charge of 55 pounds when I couldn’t check in on my phone. But the person at the desk was pleasant."
Pros: "Bought a seat 3 hours before check in and had a row to myself"
Cons: "Excellent Ryanair flight. 75% full. Very friendly crew."

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

This was a late night flight but the lights was on all the time and kids were screaming and many people were so loud. I was expecting to have a little rest on the plane considering it is late night but this way I couldn't. I think if at least the light would've been off / lower then people could feel they should be quieter.

Everything was great - but then had to wait one hour for my luggage in Verona…

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

I didn’t get to London or Amsterdam. They lost my connection flight . I was stuck in Madrid and they rerouted my flight to Austria where my son had to come and pick me up. To get to my destination and they lost my luggage and they’ve told me they can not find it very poor service so have no word for what happened

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

Overall good, but the fact that there was no WiFi was a big deal for me. I am not used to having no WiFi during long flights. I always fly Delta-KLM and they never have had an issue with WiFi.

I asked for a wheelchair. I have a back health condition. I had to walk a lot

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Boarding = No one respected the boarding groups. The ground crew did nothing to enforce the boarding system. What is the point of being a Gold member when there are no benefits to that? Tired old plane

The flight was delayed over 2 hours, we should off left the plane2 late passengers as it’s not fair on everyone who’s followed the rules.

Dreamliner. Yes great if maintained. I didn't see anyones screen work consistently during either of our flights. Worse was their ability to not only dump you out of premium but separate couples and seat someone's carer at the opposite end of the aircraft. This poor gentleman had no hand so his partner who assists him, being seated at the other end of the aircraft, well that really showed us all what Tui think :( It was fairly dire all in all, they advertise all the perks of the dreamliner only in reality you don't have the features and they change the windows and colours to suit their constant sales pitches. Ironically they were so low on stock for the return flight that all their sales pitches were a waste of time! Their contract only favours them and 'operational changes' well they cover every excuse and Tui use it. Surprisingly we haven't reinstalled the Tui app or booked with them since. It's a shame as I rated them highly during the pandemic.

One flight attendant not wearing a mask over nose, 50% of passengers not either, and no effort to correct. Boarding was very late with no information - lots of standing around waiting.
