Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

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

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

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.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Boarding and disembarking were smooth. Not offering free water was cheap ... I've never encountered that before on a flight.

Boarding could be better. To get through your gate but to be stood in a corridor for 20 minutes is not great.

The plane was postponed for over 2.5 hours, which meant that all four of us missed the check in time for our ongoing trip to Melbourne. We had to buy new tickets for 4 people as we had to forfeit the ones we had. The cost was really unfair. i understand that it was snowing during the first leg of the plane for that morning. Surely the cost could have been shared by the airline and not all by us. I could have bought insurance - but you can see how much I travel. I will need to chose more trustworthy airlines.

The true is that travel from London to Faro on 11/12/2025 by BA was cancelled, so I did not go to Faro, so i did not board easy flight. The mediocre qualification to you was because even when i bought an insurance, i could not change date neither obtain reimbursement. It could be ideal if you do something in order for me not to lose the purchase Thank you

Queuing for quite a while despite using the "speedy boarding".

Would not advise EasyJet for a 5 hour flight…small plane and hence a lot of turbulence. No inflight entertainment so struggle to pass time in cramped seats. We also fell victim to extra charge for our cabin bags, although bag dimensions were ok, but the handle was rigid and slightly fell outside their testing cage!!….never again will we fly with this airline and be party to their scams for making money!

The food and so are to expensive and old . Crew whas not very friendly . Apparently some other passenger can just Push through the waiting people to board while almost punching me and a father with a child down the stairs. Its always something with easy jet . The seats of row 26 where lose . And for a guy of my size there is absolutely no leg room at all .

Liked. The check-in was pretty quick as they had 5 desks working.

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

Economy seats were good and spacious. Much better than virgin by a mile.

It’s the old style plane with the old Ying Yang seats doesn’t compare to other airlines with newer planes.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

My touch screen at my seat wasn't working, the films BA advertised on the website for this flight were not available, and the plane was a little dated, food was good and the staff were good, just let down by the aircraft facilities.

Did not like the seating configuration at all with 2+3+2 in business class. Lacking total privacy and comfort

Check-in experience, for business call please provide a premium experience

Lost my luggage, ran out of food choices in business class, ground crew was completely unapologetic.

Excellent. The crew and flight were great. Checking in was easy and everyone was very helpful.

Late. And service was very slow - passengers sat for well over an hour with dirty trays etc surrounding them

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.
