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.

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.

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

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.

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.

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

Loupé l'avion pas pu embarquer mon bagage en soute. Pas compris l'heure de fermeture.

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

I hate Ryanair and have decided never to fly with them again, they treat you like animals on the way to slaughter and they never take responsibility for their errors and lousy service.

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

A normal Ryanair flight = too many announcements to sale something, hard landing. Otherwise, good value for money

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 5 hours and I'm and invalid,I wan a refund for this

The cabin crew on that flight were super fantastic and super helpful. They were so polite and considerate that i felt i travelled with a 5star airline.

Delayed delayed delayed - always with Wizzair. Staff were friendly and well mannered but clearly the company is unorganized and the aircrafts are outdated.

It's a budget airline. Great for short flight. Smooth landing.

4 hr delay and only told less than 2hrs before. Only given water and nuts on the flight as complimentary service. Left to wait in rain before boarding.

To be honest I did not like anything. Communication to why my flight was cancelled mid air 2 and half hours into my flight. Customer service desk were not helpful with providing information or a solution on what can be done.

I have been treated unacceptably by WizzAir aircraft crew in a previous flight, they threatened me and abused me, and I received an OFFICIAL written apology, but only two (2) months later. This flight had no such unacceptable behaviour, but it's not nice to be left waiting in the walkway (from gate to aircraft) for a long time, just so that the 'boarding' appears to be early, even if actual departure is not.

What I liked new airplane Sitting was extremely uncomfortable! Crew not smiley at all Always chewing gum

The flight was cancelled just 4 hours before the take off...

No food on board. Not comfortable. Had to move seats was delayed more than 3 hours.
