Pros: "Overall very nice flight, even comes with free drink and snack"

Pros: "The price was nice."
Cons: "Plane looked unkept on exterior. Crew was nice but lazy."

Pros: "Ryanair works very well if you follow the instructions. Check in day before departure - Don’t bring too big or too many bags onboard. Pretty perfect flight for us."
Cons: "Fellow passengers not preparing for check in and bringing too much luggage then complaining for 10 minutes while everyone else has to wait. Ryanair only had one check in / bag drop. Should be automated or more staff. Took forever. (Ok 30min and only 3 ppl ahead of me in queue)"

Pros: "The crew was helpful and friendly, priority boarding was super speedy and the food was served promptly (to my neighbouring passenger not me)."
Cons: "The seats were dirty and the plane could've done with a clean, plus I ended up with stiff knees because of how squished I was."

Cons: "Take off and arrive on time not an hour late. No trumpet this time."

Cons: "The staff are snappy with the passengers - she tried to take my coffee away from me - this was my 4th flight in 36 hours so I needed to finish it so took it back quickly !!"

Pros: "The crew and the timeliness of the flight."
Cons: "The level of comfort. Pretty terrible airplane seats, but are tolerable if you’re doing a short flight."

Cons: "Daylight robbery. I got charged 55pound for not checking in online 2 hrs before. I felt disgusted by this ridiculous amount as I had no idea. Really frustrated with your search engine and Ryan air for not making this very clear"

Pros: "Nothing"
Cons: "Kayak and RyanAir incompetence to cancel a ticked for 20 freaking days leading up too the flight. Man hours wasted 48 hours of emails and social media without resolving the issue = CANCEL THE TICKET"

Pros: "There was nothing great about Ryan air. We flew with Flybe on the way back and it was a much better experience"
Cons: "Very disappointed with Ryanair and lack of communication from kayak regarding the checking in process. This was our first time to Europe and we booked a last minute trip to Dublin. We arrived at the airport 3 hours in advance to check in and allow time for navigation. We waited in line for an hour only to know that we were either supposed to check in online or upstairs at the airport. We had 4 minutes to check in when we got to the front desk. Staff was incredibly useless and did not assist whatsoever. We had to logon the airport WiFi and watch the video then missed the checkin by 1 minute. This is absolutely unacceptable. We were then directed to another service department for a 55 pound charge each! Which was the same as our original flight. I did not receive any notification email to check in ahead of time. This was a very stressful time for my traveling partner and I and do not feel obliged to be paying the consequences given the circumstances. I am hoping kayak will honor us as loyal customers and reimburse us for these unforseeabke fees. This would be greatly appreciated. I can provide receipt and documentation if needed. Thanks"

Pros: "Efficiency"
Cons: "They made is walk around barriers carrying our bags slowly shuffling forward to get into the seated area in front of the gate. It took 15 mins . They could set up the ticket check inside the seated area so we could relax."

Cons: "Not good communication regarding delays-except from the pilot after we were waiting too long."

Pros: "Price; travel light, and take own food and it’s fine."
Cons: "Wait for the drinks/food service, and we would be on the way into land before they reach the middle of the plane on London -Dublin flight"

Cons: "The heat in the cabin was way too high"

Cons: "No pockets"

Pros: "The boarding system"
Cons: "The delay"

Pros: "Polite cabin staff."
Cons: "Delays, no information given until After entering the gate area, and even then not until after we should have been boarded. Not enough information and not clear when eventually given. Tray table and back of the seat in front were both dirty, dried on spillage from a previous flight."

Cons: "A little late setting off"

Cons: "Screwed up airport - if you're just flying through, Dublin is a MAJOR hassle. Had to leave the airport and go through security once again to connect."

Pros: "There is a large lounge at the gate at Gatwick that the passengers could have been checked into prior to boarding commencing, but this was not used. Instead, A large queue was in place for over 40 minutes and once boarding commenced, as many were checking cabin bags into the hold, boarding took about 30 minutes, delaying the flight by 30 minutes"

Pros: "But quick boarding glad I had priority"

Cons: "I don't like the fact that you have to pay to sit with your companions. As a protest for this I refuse to buy any food or drink on the flight."

Pros: "Good coffee (for £3)"
Cons: "Flight was delayed for an hour. Looked like the crew were a bit overworked."

Cons: "I had to miss one of the legs of my trip to Dublin due to connection problems and struggled to find out if I could reschedule the flight. In the end I resorted to simply missing it and booked elsewhere as there were no tickets available on either Ryanair or your site.Ryanair need to be more accommodating of people who need emergency contact."

Pros: "The price"
Cons: "It appears that all the flights are late. We ended up over 2 hours late. This has been occurring more frequently."

Cons: "Having to pay extra on top of fare to sit beside my own wife!!"

Pros: "crew very professional and friendly and boarding was quick and efficient.."
Cons: "flight price extortionate......flight delayed by over an hour resulting in me missing my bus connection and having to wait 2 hrs at airport"

Pros: "Nothing"
Cons: "The lady at check in was rude. Also how she wanted to charge us 140 pounds because our luggage was over in kilos. So we removed everything to lower the amount only to bring the items onto the plane anyway. Then there was hardly any room in the over head compartments for everyone to put their things. very counter intuitive."

Cons: "2hr 30 minute delay with no information or vouchers"

Cons: "self service kiosks were not working in airport and we were told it would cost 50 pounds each to print boarding pass. We followed directions to try to print on our own by paying for expensive internet service at the airport but still were unable to view & print boarding passes. After talking to several rather unhelpful reps, someone at the Sky Desk made an exception to allow us "free" boarding passes. This was just after 2 people were charge full price (50L each for passes & full price to check luggage, after they didn't get promised email to check bags online) Cheap fares doesn't make up for frustration"

Pros: "They got me where I wanted to go."
Cons: "I felt threatened by the generally rude staff for arriving approriatly early for my flight and packing the right sized luggage. This airline is not worth the small amount of money you pay. The next time we fly we will chose anyone but Ryanair. Overall a pretty poor experience."

Pros: "Loved the new plane and good crew, though we could not understand the announcer's English! Wild! They were nice enough, but the announcements were unintelligible. Not good in an emergency situation."
Cons: "As above the poor English from main flight attendant (purser?)"

Pros: "Clean Aircraft"
Cons: "Boarding on the flight out did the Irish Rugby Scrum proud and on this Trip it was a STAMPEDE. Please readdress the boarding arrangements, Ever the Priority Boarders were overrun !!"

Cons: "£50 x2 charge for not being checked in We checked in 24hrs before hand but they said it wasn't on the system When we checked in we checked our bags in and choose our seats. Absolutely disgusting a £17 flight ended up over £200"

Pros: "I liked getting off the plane."
Cons: "Hidden fees after hidden fees... The lady at the check in counter said my bag was fine... At the gate they said it was to big and weighed too much. £50 Extra. I bought an exit row seat because I'm big guy. The seat belt didn't fit so I asked for an extension and the flight attendant got very snippy with me and said she would not give me an extension because ​of "safety reasons". (This has never been the case on any other airline I have flown.) She then very rudely said because of your rather large size we are going to have to move you to another seat where we can give you an extension. Like I said I know I'm a big guy but you don't have to so loud and rude about it. At least say it with a smile and some kindness... Wow. It was just uncomfortable and not a good feeling. Later when I got to sitting in my new seat, they came through with the convince cart (no free snacks or drinks, you pay for everything.) She nor the other attendent with her asked if we wanted and thing, if we were doing alright, nothing. Thank God it was only a 1.5 hour flight. So glad that experience is over."

Pros: "The price..."
Cons: "The flight was delayed for over 2 hours with little information to passengers about why/with new expected times. Boarding was a mess with people all of a sudden rushing towards the door. On board, the crew seemed very flustered and was constantly rushing around, unsure who ordered what, etc. At a minimum, I would expect free coffee and water and was surprised to find out that was not the case on this flight. Not a positive experience and will try not to fly Ryanair in the future, will also not recommend to friends."

Cons: "Landing in London and then again in Dublin was very harsh. :/ Also, be prepared to pay extra for every little thing, including having them print your boarding pass."

Pros: "Missed as flight from.larnaca was cancelled"

Pros: "the flight crew was nice and friendly when they werent trying to sell you something."
Cons: "Ryanair is a bunch of criminals that prey on the Americans traveling abroad. Yes its a discount airline but my $18 flight turned into $150 after all the hidden fees were paid for. To charge a passenger 15 pounds each to print a boarding pass is absolutely ridiculous. Everyone else around us could use their phones as a boarding pass except for the traveling Americans who did not have access to a printer while on vacation is criminal. Lesson learned, I will never fly Ryanair again and will tell every American I know not to be blinded by their discount fare."

Pros: "The flight itself was fine. No issues whilst on the plane."
Cons: "The website gives option for e-bording passes but the front desk wouldn't allow them. We had to use a printer/pay for internet to get our boarding passes printed. Then they didn't even use the ones we printed off. They printed off their own."

Pros: "it was a short flight"
Cons: "Seats were uncomfortable, seats did not recline. No entertainments or snacks. The check in online is horrible, kiosk people made me queue the line 3 times to be told the same thing, they wouldn't print out boarding pass even though I checked in online, they needed a printed boarding pass. I had to pay extra for that, even though I already checked in."

Pros: "On arriving at London, Gatwick, for our trip to Dublin, discovered that Ryanair wanted 105 pounds sterling for our luggage for the 3 of us. That was a surprise I did not appreciate as was not highlighted on their website when I made the reservations. Also, the lift to allow our daughter, in a wheelchair, access to the plane was broken and her Mom and I had to help her carefully and with a lot of effort up the plane 20 step ramp from the tarmac to the plane's rear door. Not fun at all. Rick Sickles"

Pros: "Cost of the ticket but then...,"
Cons: "We could not print the tickets. Called Ryan they said just print at the airport. We arrived 2 hours before our flight and were told go back to the machine, and print tickets. We were charged 15 euros x 6 tickets. The agent said, "you should have been here 3 hours early to avoid the charge." Probably will not fly with them again. Why wouldn't they mention this when we sat on hold to tell them we could not get the tickets to print??"

Pros: "The flight itself was fine and the members on board were great"
Cons: "Terrible experience getting help, unable to print boarding pass and the lady at the front refused to help us. We got there 2 1/2 hours early and she sent us in circles trying to get our passes that we almost missed our flight because of her refusals to help us print the boarding pass."

Pros: "Quickness"
Cons: "Crying baby"

Pros: "Quick trip from London to Dublin. Clean, new aircraft. Safe flight from start to finish."
Cons: "No complimentary water!"

Pros: "Cheap"
Cons: "Flight was delayed and no on was told"

Pros: "It was efficient, quick, and an overall good flight."
Cons: "the flight was very noisy, but, fortunately, it was only an hour or so long, so it did not affect us that much."

Pros: "We arrived on time."
Cons: "The very very long wait and queue checking in at Gate 11"

Pros: "Only thing I liked was the food, and service wasn't too bad"
Cons: "Boarding was a nightmare. They warn you that you need to check yourself in online at least 2 hours before or they will charge you. We got there three hours in advance, tried to check in online but the the page always redirected you to their wifi which they want you to pay for. The only other way around this was to use the other wifi but that means we would have to do download their app. In the end, we nearly missed my flight because of all this and so we ended up checking in there and being charged £90 or $135. What a ripoff."
