Airline reviews

Pros: "Best flight in a long time - comfortable seats, good food and service, good entertainment."
Cons: "Can’t think of anything"

Pros: "Seating and leg room much better than Ryan Air!"

Pros: "Everything except the food"
Cons: "The food."

Pros: "Crew was very friendly and boarding went smoothly and ontime."
Cons: "Seats are very close together. Young child behind me kicked the seat most of the way. Bags took a very long time to come out."

Cons: "Late - again!"

Pros: "Comfortable seats"
Cons: "Slow boarding"

Pros: "Check in was a breeze with all so helpful. Cabin crew very pleasant. Very comfortable on time flight."

Cons: "2 hour delay on an hour flight"

Pros: "From check in to security to boarding everything was smooth with no waiting. Thanks for a great flight."

Pros: "When I finally settled into my seat on the British Airline and that Hostess came around and offered me a couple of free drinks that was the best thing that happened to me all day."
Cons: "For an older couple like us did not like having to climb the steps up into the Plane and being out in the rain did not help. However that was not the worst part of the arrangement between getting off the Aer Lingus plane and with so little time to reach the gate for our BA flight to Denver it was a total disaster. Due to a minor problem my wife had with her foot I had asked for a wheel-chair to be available when we got off the plane at Heatrow. Good job that I did because with out their help we would never have made it in time for your flight to Denver. Between up and down in elevators, running along the corridors, in and out of a bus and I myself trying to catch up with those poor attendants. I was sorry that I did not get a second wheel chair for my self. Only for the flight was delayed by about 20 minutes we would have missed the flight. Who ever was responsible for making the arrangements of just allowing a time of 1 hour and 10 minutes between flights needs to figure out a better time schedule before people of our age ends up getting stressed out and end up with a heart attack. Very stressful indeed, believe I will never let this happen to me again. Fly/Us you need to fix this."

Pros: "I love Aer Lingus, they appear to be always on time and nice comfy seats. No problem boarding, was nice and quick."
Cons: "Nothing to not like at mo."

Cons: "NO complimentary drinks or snacks. Seats are bolt upright. Not comfortable."

Cons: "I was unable to get my seats assigned from America. I had to go to the Aer Lingus desk when I arrived to get seat assignment."

Pros: "took off early once they had accounted for everyone, and arrived a little early too."
Cons: "While I didn't have to check my bag on the first longer flight, I did have to check it on the connecting flight which delayed me somewhat in getting into the city of London. Not awful, but strange... Free-for-all when boarding, not nearly as organized as it was at JFK."

Pros: "The efficient flight but no drinks or snacks w/o purchase"

Pros: "That it only lasted 50 mins"
Cons: "Packed with low class beer drinking plebes."

Cons: "Extremely uncomfortable. The seats were too close together and not enough room, but overall the airline is great. Will travel with them again, but will travel business class next time."

Cons: "Staff didn't engage much"

Pros: "Nice seats food was decent crew excellent"
Cons: "Not enough room"

Cons: "Nothing, excellent trip"

Pros: "Swift boarding process, mannerly stewards"

Pros: "The flight was quick and smooth. We didn’t have any trouble getting onto the flight and finding our seats."
Cons: "I didn’t like that there was no complimentary drink service . When they came around with tea or coffee is was 3€, I wasn’t informed that until after I asked for a tea. I would never have got it otherwise. That may have been my misunderstanding since on our other Aer Lingus flights we had been given complimentary tea."

Pros: "Flight attendants were nice looking, very friendly, smelled nice they could not have been warmer people!!"

Pros: "everything was good as usual"
Cons: "check-in desk couldn't check me through to my connecting flight with Virgin Atlantic so I had 15mins once landed in Heathrow to get through passport security and checkin at Virgin Atlantic desk.... I'm young and fit so was able for the dash but elderly or familys would not have made the connecting flight in that time"

Cons: "Paying for beverages seemed a bit much."

Pros: "Crew, speed, ease of security at Cork"
Cons: "The lady in 1C who turned her phone on as soon as we hit the British coast"

Pros: "Crew polite. Seats comfy."
Cons: "One person checking boarding cards at gate led to a ridiculously long queue for a nearly full flight and made it late getting us all on the plane and passengers were getting annoyed. Then whatever machinery Aer Lingus use to push the plane back from the gate actually got stuck on the plane cone leading to another delay. Knock on was we were made to wait for a take off slot and made to wait for a landing slot at Heathrow so late arriving."

Pros: "Reilly dolly"
Cons: "The other trolley dolly"

Pros: "Punctual and on time"
Cons: "Nothing really"

Pros: "The British Airways portion was exceptional! The Aer Lingus portion was not!"
Cons: "On Departure for Dublin, waited in long line to check in at Aer Lingus only to learn it was co chaired by British Airways, so Aer Lingus would not service us at all. We had no way of knowing since it was sold by Aer Lingus and had an Aer Lingus flight number. Tried to check in on line, but was unable. Waited for Aer Lingus customer service on telephone customer service for more than one hour and finally just gave up. Aer Lingus has no Customer Service at all. Do not deal with Aer Lingus under any circumstances. British Airways met our needs!!"

Pros: "We left on time and landed a bit early. Only 1 1/2 hour flight, so no food, drink or service, but it got us there."

Pros: "Efficient staff and timely I would book again for sure"

Cons: "The problem I had is that this was not a British Airways flight, nor were my flights to Dublin. I was not aware of this. When I checked in online I was allowed to check in with British Airways, so I had no idea that this was an Aer Lingus flight, which is in a different terminal with a different flight number. My phone didn't work in Ireland so it was extremely difficult figuring out where I should have been. If I was on a different airline that is affiliated with British Airways, and I booked through British Airways, there should be some way of looking up where I should be going. Also, any emails about my trip should have told me which airline I was on. I fly often, and often to other countries. This was the most confusing and difficult flying experience (the entire trip -- getting to and from Dublin) I have ever had."

Pros: "We landed safely."
Cons: "Mobile check-in not an option. Seats not available until check-in without paying. Nothing is complimentary on a rather expensive flight."

Cons: "I requested an aisle or window seat and was not able to get one."

Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"

Pros: "The fact that I could charge my i phone..."
Cons: "The lax attitude to service and customer satisfaction there was a problem with the entertainment system, took over an hour to get attention... But no positive resolution..."

Pros: "Very polite and helpful."
Cons: "Unknown"

Pros: "We were late for our connecting flight because of a plane issue and no one from the Air Lingus did anything to help us get to our next flight out of London to Munich. We asked several times and they said follow the signs ."

Cons: "We were delayed by 2 hours and we missed our connecting to Bangkok from London. Which resulted in queuing with two small children for 4.5hours then we luckily were given a hotel, but we missed a day of our Thailand holiday."

Pros: "Nice crew"
Cons: "I booked my flight in March (for travel this June) to make sure I got a window or aisle seat. When I checked in (on this flight and on my flights to Dublin) my seat had been changed to a middle seat, and there was no way I could change it back. Also, I was not able to check-in online the night before, like I have been able to do on some other flights in the past."

Pros: "Absolutely nothing. Dread the return flight"
Cons: "Plane was to take off at 0740 and finally took off apx at 0850 we missed our train had a hassle changing our tickets. Staff on this plane was exceptionally rude. Couldn't even get a free glass of water. You would think because of the long delay a complimentary beverage would be offered. Would like an upgrade at no cost for the return flight for us"

Pros: "Friendly ground staff at Alicante airport."
Cons: "Airplane was dirty, floor covered in food from previous flight."

Pros: "Lovely crew, comfortable seats and bang on time."

Pros: "Nothing about this flight/airline was good."
Cons: "A different airline."

Cons: "Ryanair website did not work properly for check in and I was charge 110euro extra upon arrival at Athens airport - myself and my fiancé are very disappointed. We arrived at the airport 2 hours before our flight and we were told we could not complete our check in process as it was only available online. The flight had delayed 1 hour and we still payed 110 euro. The crew had very rude attitude. This was the first time flying with Ryanair and it was a complete disaster. I believe it is unacceptable to pay for something that it was not my mistake and I except to receive a response from you soon."

Cons: "No issues"

Pros: "Most uncomfortable seats I have ever been. The Thames train link seats I took to St Pancras was 10 times better. 49 minutes late departure from Athens and not a single word of apology. The crew onboard was friendly."
Cons: "You figure..maybe say we get some compensation for the delay?"

Cons: "AC needs to be on as the cabin was extremely warm on entering"

Cons: "I don't mined the flights it is the long walk to the plane."

Pros: "We arrived at our destination as did our bags"
Cons: "Boarding experience, timely departure, menus available to peruse, staff attitude poor, variety of options limited for an 1145 flight.......I could go on but they don’t care anyway!"

Pros: "Quick flight, low cost."
Cons: "Didn’t follow the rules with the checked bag as was unclear. No problem, but staff member aggressively explaining over and over when understood the first time. Would rather have just been charged than getting and ear bashing. Staff were main problem, not particularly friendly. Fault with plane?"

Pros: "It was on time"
Cons: "No back steps when landed To long to disembark"

Pros: "Busy but efficient"
Cons: "Waiting too long for baggage"

Pros: "I got an email from Kayak letting me know that my flight was delayed from Shannon to Stansted I received the email at approx 23:00 the night before the 07:00 morning flight The email told me the flight was 3&1/2 hrs late Ryanair let me know at 0750 on the day 10 mins before take off A joke So thank god for kayak what an app Brilliant keep up the good work 3rd Jan 2019 flight FR102"

Cons: "One hour late."

Pros: "Good flight and cabin service - on time."
Cons: "Long walk to gate. Boarding was like herding cattle. Far too few seats in departure lounge."

Pros: "Nothing"
Cons: "Should be more information instead of waiting around airport They must know when a planes going to be late"

Pros: "The flight crew were friendly when we finally got on the plane 3 hours late"

Cons: "Departure was nearly 30 minutes late!"

Pros: "The most relaxed Ryanair flight I have ever been on"

Cons: "Noisy passengers (stag party and 40birthday)"

Pros: "Flight was smooth nice and on time"

Pros: "The crew were very friendly and very helpful with my sister struggling with her baggage due to her breaking her arm a few weeks ago. The crew on the ground at Shannon and on-board the flight could not do any more for us."
Cons: "The seating arrangements whereby we had to pay extra to sit together despite us booking the three tickets all at the same time. Ryanair are over-charging their customers with these hidden charges which are only declared at the check-in stage"

Pros: "No quest when we boarded. Hand luggage was allowed inside the cabin and not placed in the hold as has been on the last few trips."
Cons: "the quality of the announcements is poor. The staffs accents are so heavy that the announcements cannot be heard and or understood."

Pros: "Great staff and flight on time"

Pros: "Very cheap flight, attentive and polite cabin crew"
Cons: "Delayed flight but left standing at the departure gate in Dublin waiting 30 mins for no reason"

Pros: "Got an extra leg room seat when asked for it"
Cons: "Late arriving got of plane was left waiting when asked when the bus to terminal we were told it's wierd it's Stansted airport"

Pros: "Crew attentive and helpful"
Cons: "Having to pay for drinks. Even water. Other carriers you get food and drinks free. Ryanair might say it's cost saving but readjust can do it. And £3 for a bottle of water is ridiculous."

Pros: "Great Flight. Great Staff"

Pros: "Not alot,crew was pleasent and staff in London were lovely"
Cons: "Small seats, uncomfortable,over priced drinks and food terrible landing.delayed"

Pros: "Always travel Ryan air when possible just returned from Italy having flown with them so was disappointed when we were just left hanging around with this flight"
Cons: "Not being told what was happening having people waiting at stanstead paying for parking"

Pros: "Cheap as chips and only took an hour instead of 90 mins; happy out!"

Pros: "I randomly was allocated the emergency exit aisle so not all bad, however my bag was placed in the hold therefore delaying the experience home."
Cons: "Blunt staff, poor check in process, sold too for the whole fights. Sat away from my misses although there was a spare seat next to me."

Pros: "Staff is ok"
Cons: "Flight delayed more than 1.5 hours. We were seated apart."

Pros: "We paid for our seats but the staff decided to move people that were separated due to Ryanairs booking system to move with us who had paid for seats. No good"

Pros: "Left on time arrived 20 min early"
Cons: "Poor airport facilities then poor seating on aircraft. Lots of fractious children on board more time spent in aisle than seating. I was constantly bumped throughout flight"

Pros: "The flight took off to time"
Cons: "Making us to wait in line for over 30 minutes to board the plane that came in with passengers right in front of us. No entertainment on board at all. No wifi"

Pros: "We didn't crash"
Cons: "Our flight was late to take off, and had to queue for 30 minutes at Shannon - before the plane had even landed. At stansted then had to get a long bus to the terminal and wait on the bus for 10 minutes because they couldn't open the doors. Luckily after a sprint to the station we made the last stansted express of the evening (£28 return each - 'London' airports for you)"

Pros: "Not much."
Cons: "It was a total faf in the airport in Marrakech. Things work differently which is fine but the airline should really inform you that in order to progress through to passport control you need to go to the check in desk (even though you checked in online ages ago) to get a stamp. It took ages and ages and the lack of communication was annoying. Ryanair sent out an email warning about longer security waits but didn't specify. The problem is most people who travel Ryanair don't have bags to check in so naturally like every other place you would go straight through. And if that's not the case then tell people!!! Very frustrating."

Cons: "Uncomfortable seats"

Cons: "that we need the Ryan Air app and can't print our boarding passes at the airport."

Pros: "Staff were very good, although tierd"
Cons: "Being delayed by a technical glitch"

Pros: "Price was right, staff were pleasant and helpful. OK for short haul flight."
Cons: "Reservation couldn't be found at check in, check in clerk had to manually force a boarding pass thru system."

Pros: "I like the price!"

Pros: "We were " made" to put our bags in the hold. We accept that after 90 passengers this is usual, however on this occasion we were tight for time and the other queue boarding the same flight, that came to the gate late were not "asked" to put their carry on bags in the hold. Poor service Ryanair, what would happen if we refused? It was done in an unfair manner and when questioned we were brushed off with a mumbled response. We will look at other low-cost airlines in future."

Pros: "Very cheap prices. Everything is extra. Seating is cramped, but for a short flight it's doable. Lots of destinations and at various times."

Pros: "Staff were friendly, no delays and we arrived on time! No complaints"

Pros: "The price was fantastic! the best around :)"
Cons: "There was no notification from cabin crew to advise us to ensure we collect our luggage BEFORE we go through the glass doors at Gatwick. We were expecting to show our passport and collect our luggage from the carrousel but didn't realise until after we went through the glass doors and had to wait over 40 mins for it to be brought to us. What was so astonishing- we were told we weren't the only ones this happened to. It would be very useful if cabin crew made the passengers aware of this to avoid it happening time after time with others/flights"
