No hot drinks but otherwise a good flight with decent leg room

No hot drinks but otherwise a good flight with decent leg room

The boarding at both ends good, the seats were a tad hard for any long flight, but okay for short haul, 2A and 2B had good leg room. On the return flight we landed at terminal 2 as opposed to where we should have land at terminal 1, so we had a bit of a wait for a bus, which delayed the onward journey. But all in all a good flight.

The flight was okay, seats slightly more comfortable than Easy jet, but wouldn’t want to fly much more than 3.5 hours in those seats, hard and uncomfortable for further journeys. Boarding was okay, never eat or drink on Eco airlines, food not good and expensive for what you get. But it is what it is, and for the price one can not really complain.

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.

The trip itself was good. I have given only good as rating, because my first flight has been cancelled by a different airline and that caused disruption in my trip. I spent over ten hours in Luton airport and that caused me high tiredness, sickness, because of the very early initial trip. easyJet staff has been professional and friendly.

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.

Total jobs worths over carry on bags, charged £96 extra for bags that were clearly hand luggage

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.

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

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.

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

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

The Ryanair staff was not polite. We all travelled with the same suitcases as we departed from Thessaloniki, however they decided that for some passengers the suitcase was not the rigth one as far as the dimensions are concerned. Furthermore, one air stewardess asked passengers to close themselves the luggage cabinet in order to prove that the lugagge was not properly fitted, which i think is very unkind and unprofessional. We also had to wait outside , some metres away from the plane until last passengers came off....It was generally a dissapointing experience.

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.

Great flight and reminded that the logistics completely Astoria. No real story about victors, m

it s a budget flight, crew was doing their job well, it was on time.

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.

We paid to have overhead carry-on baggage. When we got to the gate we were told that our carry on bags would need to be checked and go below because the flight was full. Notably we were nowhere near the last people to board and about 30 other passengers also had to check their carry-on bags. Other than that the flight was fine.

Very bad plain although I paid A business class ticket I was stuck in a stiff fixed seat without any entertainment or Wi Fi for 5 hours I will never ever book a flight on British airline.

Self check in Kiosk did not recognize that I had prepaid for my luggage. This caused a 40 minute delay even though I had my British Airways email receipt for the prepaid luggage.

Crew were very friendly and helpful. They explained to us in detail the delay in our takeoff due to the storm that rolled in from Belfast and did their best to make up the time. Always great to fly BA!

Staff were very helpful. The free WiFi for messages was also very useful to keep in touch

Crew was more interested on looking at their phones than welcoming passengers during boarding.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

Offered vegetable curry when it was actually tofu which I don’t care for.

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.
