Airline reviews

Pros: "quick entry - but it was not a full flight!"

Pros: "The pilots gave details of flying conditions and landing conditions. Flight was smooth and on time"

Pros: "Crew was great and movie selection was good. And the food was also good"
Cons: "It was all good!"

Pros: "Friendly"
Cons: "Lost my luggage"

Pros: "Crew was very nice and no surprises while boarding at the gate"
Cons: "You had to pay for snacks or water"

Pros: "Efficient crew on board"
Cons: "Long lines, late plane, could have started with two ticket people instead of one since plane was already late. Friendly crew though"

Cons: "Could have been on time - 40 minutes late"

Pros: "Very good crew. Friendly. Smiling. Helpful. Short flight. 50 min."

Pros: "Crew very friendly. Decent leg room in economy"

Pros: "nothing"
Cons: "no communication and a few apologies6"

Cons: "Tough time. British airways wasn’t very helpful. Once our gate was changed no one told us or gave new boarding pass. We did have 7 hours to figure it out. But a clue where to go would have been nice. Missed my connection. Shuttle and hotel was a mess. Got a few hours of sleep outside the airport. Maybe I’ll get to Los Angeles soon."

Cons: "Could you refund me 50.00 as your price included bag price but when directed to book I had to add on bags for a further 50.00 and because of this they wouldn’t let me get on an earlier flight on my return sueevans999@hotmail.com or 07799411994 for response"

Pros: "Fruebdjf, courteous and good food."
Cons: "Nothing!"

Pros: "Overall it was fine. Friendly staff, everything pretty efficient."
Cons: "Truly disappointed to find that BA has decided to charge for ANY beverage whatsoever, even tea. I have such fond memories of flying BA years ago. My husband and I so enjoyed the disposable plastic blue teacups that we brought them home with us and still use them as kitchen scoops all these years later. I know that may seem silly, but even without that nostalgic memory, it just feels SUPER unpleasant to have to pay for the basic (non-alcoholic) beverage service. Honestly, just charge a few bucks extra on the ticket in the first place."

Pros: "Polite crew"
Cons: "Waiting for an hour to disembark"

Pros: "The staff was nice"
Cons: "You've got to pay for a can of ginger ale now? When did British Airways become a budget airline? What a joke. The plain is an old outfitting with flip down screens and whatnot. It's not like we need these things for shorter fights, but why would anyone pay more to fly a nicer airline if you're treated like you're on Ryan Air?"

Pros: "Great flight"

Pros: "Gate agents good. Same with cabin crew"
Cons: "No AC charging. Legroom in business was tight"

Pros: "I appreciated the brand new seats on the aircraft which were quite comfortable, and the friendly crew who actually were nice enough to have a conversation with. Enjoyed the Marks and Spencer’s food too."
Cons: "The boarding at Dublin airport was not great, masses of crowds from every displaced flight due to snow (not all British Airways, many other airlines adding to the crowd). Was not awful but not fun."

Pros: "Great service as always"

Cons: "The only complaint I have is our bags getting lost twice. I’m very understanding that these things happen. But for it to happen twice seems like people might be careless to the problem."

Pros: "The flight attendants were great, helpful and polite. The food was delicious and there was planty leg room. A great airline to fly with and I'd highly recommend them."
Cons: "Nothing, all was great."

Pros: "Great staff, ultra professional"

Pros: "Finally getting to my destination 3 hours late."
Cons: "Issues with check-in, flight delayed multiple times, gate changes multiple times, non communication from attendants."

Cons: "Small plane"

Cons: "The change of seats with the motove of keeping balance on the plane"

Cons: "I am 6'3" and I cannot find sufficient leg room. The answer is paying additional for seats with extra leg room, is no answer at all. The answer is quit jamming more seats in to a ever shrinking cabin."

Pros: "This was a BA codeshare but operated by AerLingus,supposedly a 4* airline."
Cons: "So called 4*"

Pros: "Quick flight"
Cons: "No complementary drink or snack on flight and no entertainment system available...they said it was because of a short flight. You could buy drinks though of course....."

Pros: "On-time arrival"
Cons: "Seating was very packed"

Pros: "All staff were very helpful and polite"
Cons: "This flight was delayed. When it came to boarding my husband who needs special assistance was first taken to board first but then had to be brought back as refuelling was not done and was then last on board. When we arrived at Heathrow his special assistance was not there and we had to wait for about 10/15 minutes. It is stressful traveling with someone who needs help and even worse when there are delays. We were advised that we could leave the aircraft which we did but we were left waiting in an area without any toilets which is a problem for him"

Cons: "No wifi. No tvs. 1985 just called and they want their no entertainment airplane back. This is 2017.... get with the program!"

Cons: "Both legs were late. Outgoing was significantly late. Surprise charge of 75 euros to check a bag. Almost as much as a seat."

Pros: "Attendance were friendly and helpful and courteous. The plane was clean and we arrived ahead of schedule."

Cons: "No food, and no entertainment. An older airplane"

Pros: "Comfortable seating"
Cons: "No beverage service."

Pros: "Clean."
Cons: "No complimentary drink or snack, how come?"

Cons: "We are really upset that Aer Lingus and/or Bitish Airways lost our baggeage! All our clothes, toiletries, medicine, and other personal belongings are MIA and we want these two airlines to work together and expedite finding and tertuning our luggage."

Pros: "British Airways offered me a direct flight from Dublin to Philadelphia on their sister carrier American Airlines."

Pros: "Short flight but thought there would be beverage service????"

Cons: "Rude at check in. Late taking off."

Pros: "Great meals, entertainment options, and service. Perfect landing of the 747 as well."
Cons: "Not the fault of British Airways, but Denver International Airport has a cumbersome and lengthy process for the re-entry of U.S. Citizens. We stood in two different lines for over an hour to be screened for customs."

Pros: "swift boarding allowed for an earlier departure and arrival 30min ahead of scheduled time"
Cons: "I waited 30min at the priority check in queue while being first in line this whole time. There was only one counter open for normal check in and one for priority when I arrived and after 20min waiting, the priority counter closed completely and there was just one counter open remaining, with just 10-15min before the check in closed. We had to wait another 10min to be able to check in our luggage! On arrival, luggage took 45min to just start delivering, completely wiping out the 30min arrival ahead of schedule."

Cons: "The sign said it would board by rows but they did general call and it was ridiculous on a flight this large. Nothing"

Pros: "Staff was cheerful"

Pros: "Everything was fine."
Cons: "Small seats."

Pros: "nothing"
Cons: "they lost all our luggage"

Cons: "We were late taking off due to the airport and plane not sharing passenger data, and then forced to delay exiting the plane and then forced to sit on a bus rather than enter the terminal."

Pros: "Boarding was fast and efficient, friendly crew, on time!"

Pros: "Cheap, saved me when I was in a pinch, and easy check in. I loved being able to check in on the app and check my own bag!"
Cons: "It was difficult to understand what the flight attendants were saying over the intercom. Between the masks and the intercom, nothing came across well. Please continue to wear masks, but perhaps find a clearer way to communicate for those of us that are hard of hearing. I was too embarrassed to say “what!?” 84 times. It’s not their fault."

Pros: "I went airport for boxing pass they changed 165 £ if some one dnt no"

Cons: "Less time at the AirPort after landing"

Pros: "never ever use this Momondo again"
Cons: "no customer service"

Pros: "Politeness of the staff"

Pros: "Online booking was nice and easy."
Cons: "Plane was small ,seats were not comfortable and plane was not connected with eye so passengees were waiting outside of plane in cold weather."

Pros: "Very quick. Great service"

Cons: "App was down couldn’t check in had to pay cash(euros for trip). 250 euros for 180 pound as Ryanair only accepted pound (had to change at airport hence the rates) absolutely disgusting"

Pros: "Cheap(ish)"
Cons: "Worst plane seat of all carriers. No leg room, to close to seat in front no where to put anything , no usb charger. My local bus is more comfortable & better equipped. Same as 90% of people only fly Ryanair as a last resorts. Friend tried to down load boarding pass in the morning of flight was not able as need to be done 24hrs before. 50 euro to get printed at airport outrageous. Perhaps you could Justify £10 but 50 euro!! Why do they try so hard to rip there customers off at every turn"

Pros: "Staff on Ryanair always pleasant and good good, flight smooth and always on time"
Cons: "Nothing about this Flught I didn’t like"

Pros: "The prices were ok. I’m short (5,4) so I can’t complain about the leg space. The cabin crew were pleasant, I can’t say the same about al the workers in the airport, ruining your mood before a holiday is slack - especially after"
Cons: "Not all of your staff are polite, I’m not sure if it is because we were in a country that does not accept or respect people of “colour” but I could see that there was definitely a heavy line of different treatment to other races - sadly from a very well known brand. I did feel the luggage prices were slightly tacky, and extra for on cabin prices. Also, cleanliness is clearly not a priority for all either."

Pros: "Very chip flight but expensive tricks about luggage paid my cabin bag but not allowed to check them I will never flight with Ryanair air."

Pros: "It was affordable"
Cons: "Customer service"

Cons: "Very bad service. Everything is bad"

Pros: "Trip went well easy check in Know problems"
Cons: "The stay was too short would like to have had more time in Copenhagen"

Pros: "Took off on time"
Cons: "Random seat allocation due to not paying the extra fee?"

Pros: "I slept as soon as I found my seat - as did Mr. (very) Longleg next to me. Could not lean back, but never mind, it was a short flight."
Cons: "taking a cheap flight - take it or leave it. I'll do it again."

Pros: "boarded the plane to find it looking like there had been a kids party. food all over the seats and floors, rubbish under the seats. pilot was barely competent making a harsh fumbling landing"
Cons: "disgusting plane"

Pros: "Decent enough flight, seats comfortable enough for short haul wouldn’t want to go long haul on the same seats, good selection of onboard snacks"
Cons: "Flight was half hour late, priority seats should be reserved for the first seats on the plane rather than scattered all over the plane, suitcases shouldnt be allowed on board they take up too much space for anyone else and slow down the boarding of the plane as people attempt to haul them up the stairs, some staff could be more polite and less abrupt and some could attempt to speak louder and clearer"

Pros: "Service and comfort means ryanair"

Pros: "Ryanair still don’t have enough leg room for taller people. Very uncomfortable. Cheap but not that cheerful if you’re over 6 ft"
Cons: "More leg room or exit seats for taller people"

Pros: "Nothing."
Cons: "Delayed for three hours then they gave us a 5eur/£3.50 voucher which we were only allowed to use for pizza and WATER. No other soft drink. The delay was ridiculous. The allowed us to board and be seated for about 15 mins before telling us that there was a problem with the aircraft. DONT YOU CHECK THIS BEFORE PASSENGERS BOARD?! Priority was a waste of money we all got on at the same time anyway. Rubbish service, rubbish airline and my £26 flight turned in £60 easily with all the extras which were a waste of my money."

Pros: "We made the flight!!"
Cons: "Notification of which Gate!! All the steps Down to the tarmac then up the plane steps!!! Priority- didn't seem to mean anything- everybody boarded the same!! The Cabin crew- Rushed announcements!! And worked as I feel robots!! But definitely got Value for Money!!!"

Pros: "Seat was fine considering the cost."
Cons: "Ok but i accidentally started queuing in the priority queue and was told that i needed to be in the other queue, even though i was there very early on. I think i should have been allowed to join the other queue at the same spot but went to the back of the other queue. Apart from that it was fine"

Pros: "Perfect timing."
Cons: "Nothing"

Pros: "Online Check-in early"
Cons: "flight takeoff was delayed by an hour. No explanation was given at all"

Pros: "Quick boarding"
Cons: "I didn’t like the fact that there are lots of hidden fees, with the seat, luggage, etc. It is true that the ticket is cheap but paying the hidden fees adds up to the cost."

Pros: "Nothing"
Cons: "Seating uncomfortable, don’t even serve water, charge money to check in 3 days early and for some strange reason they charged 100€ for standard carry ones manufactured by Samsonite for international travel because it didn’t fit in their standard cubby ... the same carry ones they allowed from London to Stansted became a tad too big on return . They remind me of US traffic police that start giving tickets on tiny issues st the end of the month to make their quota . Also many people in the line had bags exactly our size"

Pros: "Cheap & Cheerful, as usual"
Cons: "Delayed Boarding Delayed Taxi Delayed dis-embarking (no dispatcher) just two bus drivers and no unloading of cases o those with mobility issues"

Pros: "Spacious seats with leg room"
Cons: "Too much talking over intercom"

Pros: "It was a stress free journey. Which I will be doing at least 4 more times this year"
Cons: "I cannot think of anything. Except you can't buy duty free cigarettes on the trip anymore"

Pros: "The plane was so empty, we were allowed to change seats so I sat by a window seat and had the whole row to myself! Also, the plane was warmer than usual, which was kinda nice."
Cons: "It was delayed by 40 minutes."

Pros: "I had a good flight either way. Some turbulence, what you might call 'a controlled crash landing' on the way back to Stansted."
Cons: "The price of the flight. I normally am able to secure a return flight for about 100 euros. This time I got a quote for 300 plus for a return flight. Going through an affiliated site helped me to get a slight reduction on the flight. I find it odd that on a Thursday or a Tuesday the cost can be 12.99 pound either way and yet on a weekend this goes up to a silly amount. The flight is still the same. I am still going to the same place. Having to book three months in advance to avail of a cheaper ticket is of no use to me. The girl checking us in on the outward journey had her back to us the entire time when making an announcement for boarding. She looked like she was sucking sour sweets. No friendliness about her at all. Passengers using overhead spaces different to where they are sitting. That's really irritating."

Pros: "Nothing"
Cons: "All"

Cons: "No tv or entertainment"

Cons: "They didnt took care for me reach my destination. Even After they they new that was ryanair mistake."

Pros: "Cheap"
Cons: "Delay"

Pros: "Once I was on the plane I fell asleep so it was a good ride."
Cons: "When we got to the airport no one was willing to help me which ended up costing me an extra £100. I was so upset and no one even showed the slightest care. Im never flying ryanair again."

Pros: "Nothing"
Cons: "Snobby customer service rep that charged us 15 to print boarding pass when their site was down and would let us view our boarding passes. (When we had previously checked in and seen them online)"

Cons: "Late departure"

Cons: "Gum and candy wrappers stuck in the sides of the seat. Crew spoke poor English. Co-fliers were loud, drunk and unruly."

Pros: "For the price I paid the flight was quick. On time. The staff was really polite and the plane was clean. Definitely would fly with them again on short trips and would recommend them to friends and family."

Pros: "Availability to change seat if one is open"
Cons: "No leg room"

Pros: "Cheap, efficient, works!"
Cons: "Customer service is just bad. We had to self check in and self drop bag. We intentionally went to a lady to help us she said "this is self check in and you have to do it alone", in the process we had a mistake so she asked "why did you do that, the machine told you not to" - that's exactly how you should NOT treat your customers. We thought our luggage will not arrive - and she was rude and stressing us out. 0/10 for her"

Cons: "The crew had to rush the announcements and introduction because of time restraints, this made it unintelliagable. The safety part was fine"

Pros: "We bought Ryanair because of the great price. However, they do charge extra for everything and fly from an airport that's an hour away from London. If you count all the extra cost Ryanair is far more expensive than any other airline"
Cons: "Price"

Pros: "The whole process went smoothly"
Cons: "Temperature changes very contrasting. Ok in terminal, boiling hot waiting on staiwell, cool walk to plane."

Pros: "It was short so there wasn't much to do, no screens or anything but that was fine. I thought it was great."
Cons: "I think it was a bit overcrowded. There wasn't a lot of space for people and some had to put their bags at the back of the plane."

Cons: "The cabin was a little dirty."

Pros: "Nothing"
Cons: "Ryan air's cold blooded policies"
