Cons: "When a bought my ticket, I had asked in the office about WiFi. They told me that you have WiFi on the plane. I had checked this information on KLM.com and saw the same, that you have WiFi. This was the reason, why a chose KLM! Then I tried to connected on board but I couldn’t! WiFi was not available. Crew told me that they don’t know anything about it! I was disappointed and angry."

Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."

Cons: "I paid for the preferred seat .and i found that people beside me didnt pay anything when i asked them ,"

Pros: "The crew tried to be helpful but were equally frustrated with the ground crew."

No rushing was needed though, the flight was delayed for 1:30h and after we all boarded a further delay was announced. I will never fly with KLM."

Cons: "Tiny old cramped plane."

Pros: "Good efficient flight crew friendly and helpful"

Pros: "Very little if any."
Cons: "Aircraft was not very clean,the staff seamed quite harsh at times when speaking to customers. The food was really quite poor but it was a short flight to be honest. Overall not as pleasant as the China Southern flights. I would not like to choose them again unless i had to."

Cons: "Not only was there free food but they tried to sell you a bunch of stuff. Not a moments piece."

Pros: "It was so easy to board and I had no inconvenience. It took 4 minutes from when I said goodbye to my family till when I was at the front of the gate."
Cons: "Nothing! It was all great!"

Cons: "Long stop over at Schiphol. Too Long!!!!"

Cons: "magazines very dog eared and some badly torn"

Pros: "The flight was delayed due to fog, but the staff was amazingly helpful to make sure everyone got to their destination."

Pros: "The cabin crew, the flight and communication and the cleanliness of the plane."
Cons: "It was really unclear which desk to use at Birmingham airport to check in. It was extremely stressful for a first time flier as I had no idea what to do - the desk location wasn't marked clearly and when no staff were there it wasn't clear that the desk was open."

Pros: "The flight was delayed by 40 minutes initially then a further 20 making it an hour late. Sitting at the gate there was then suddenly a last call to board the flight and a mad rush for everyone to get on. I appreciate that delays happen but the lack of communication ragardinh altered boarding times didn't make the situation any easier"
Cons: "As above"

Pros: "Staff superb. They even surprised us with an exit row and a gift for my partners birthday! Amazing. Samantha and Dennis also took time to come and personally wish him a happy birthday. A lovely touch. This airline runs like clockwork. They are just great. The sandwich and stoop waffle are nice too."
Cons: "There is a bus to the plane, so that takes a bit of extra time but they are very well organized."

Pros: "Flight was efficient enough and staff were friendly."
Cons: "It was delayed quite a bit and more on-time updates would have been appeciated."

Pros: "Short, comfortable flight. Nothing special. Got us where we needed to be without incident."
Cons: "Nothing. This is filler text to meet the min. characters."

Pros: "Same as above"

Pros: "The crew were very friendly and accomodating, plane was clean and boarding amd disembarking was efficiently handled."
Cons: "55 minute delay was not welcome."

Pros: "Flight unpleasant. Ground staff in Marseiile great but gate crew didn't control carry on baggage and many of us could not use overhead bins because of passengers who stowed more than one and often oversized suitcases above, so we and many others had to place carry on suitcases under seat. Attendant on plane totally unhelpful and could have rearranged a few bags to make room but preferred to stay in back of plane and talk. To be fair, rest of flight was pleasant although late due in part to boarding issues."
Cons: "Carry on baggage issues and storage on plane. One aloof and unhelpful member of flight crew."

Pros: "Except for my negative comment, a good flight."
Cons: "I paid extra for a window seat, but due to the poor alignment of the seats with the actual windows, I actually sat next to a wall! Nol much to see out of a wall. If KLM are going to charge extra for a window seat, then they should make sure there is a window there! If the seat had actually had a window it would have been an excellent flight."

Pros: "They were nice, rushed through beverages, but since it was a short flight that's understandable."
Cons: "The top cushion on the seats could be less bulky."

Pros: "crew was super nice"
Cons: "major delay, no info, boarding process felt like a cluster"

Pros: "Comfortable, good food and good crew"

Cons: "Flight was late due to earlier mechanical error. These things happen but still annoying when they do. Crew didn’t seem too bothered."

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

Cons: "Best flight I have ever been on"

Pros: "Nothing"
Cons: "Everything"

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."

Pros: "Hostess were helpful and friendly"
Cons: "Middle seat in first row and my bag half way down the plane so although I could’ve been first off I was in actual effect the very last."

Pros: "Yes"

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."

Pros: "Shannon is a very easy airport."
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."

Cons: "Paying for inflight drinks. All US airlines provide FREE complimentary drinks and snacks. Seemed in poor taste to charge for such things made the airlines appear cheap."

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."

Pros: "Short but great had a window seat so slept most of the time"
Cons: "Staff didn't engage much"

Pros: "Fast efficient boarding. Short flight so no issues."

Pros: "Boarding went quickly but there was no discomfort on the plane. Staff was friendly and efficient and they made an effort to take off and arrive early to our destination."
Cons: "Nothing, excellent trip"

Pros: "Swift boarding process, mannerly stewards"
Cons: "When landed, the back door of the aircraft was opened, despite passengers only disembarking form the front. It was very cold."

Cons: "Terrible"

Pros: "Was part of my international flight"
Cons: "Was part of my international flight"

Pros: "Quick Boarding"
Cons: "Flight was delayed for an hour"

Pros: "Does not apply"
Cons: "Does not apply"

Cons: "I am tall and I find the rows too close to eachother"

Pros: "Friendly staff."

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: "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: "Custom made bike box erroneously classified oversized, but they didn't charge for it so ok"

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: "Journey was good"
Cons: "Air lingus checked on my bag under someone else's name, now I am stuck in San Diego with no luggage and no answer as to where my bag is, very disappointed"

Pros: "Speed of boarding from both the gate crew and the cabin staff. At that hour of the morning the last thing you want is hassle when boarding."
Cons: "It's a very very early morning flight."

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: "Boarding was quick and efficient. I was seated quickly and the flight took off on time. No complaints."

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: "The personnel involved with wheelchair services who took us to our gate was very helpful and engaging. We thank them for this service. The gate personnel and flight attendants were helpful to get us on the flight earlier that was helpful with my husband" visual disability."

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: "Friendly crew."
Cons: "Having to use steps at Cork airport . The cost of tea served in a disposable cup is too expensive."

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: "The planes were comfortable and the online and airport check-in process goes smoothly."
Cons: "Not even water is available to passengers. And flight attendants must shill to SELL food perfumes and merchandise during the entire flight. It seemed very unseemly that professional flight attendants were forced to behave in such an unprofessional manner. Sell, sell, sell is their job on Aer Lingus."

Pros: "Crew wonderful.N"
Cons: "None for now."

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

Pros: "Business class lay flat seats allow sleep. Staff tries to pamper you with good service. Smooth long flight 10hrs40min and flight left 30 min late and still arrived early 40 min."
Cons: "Online checkin requires passport check at airport so you try but cannot print boarding pass. Online would not let me order gluten free vegetarian meal for daughter, but staff at terminal said oh it is too late now, you need 24 hrs notice... on flight though they figured it out and brought her foods she could eat so it worked out ok."

Cons: "Food needs a taster to approve it. Not in the laboratory but on the plane"

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

Pros: "Really liked the flight staff.. great service and all very humorous. More room than on most flights and everything was on time"

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"

Pros: "Service manager Alan and crew were lovely, very friendly and felt genuinely happy to help us. I have never been given so much free stuff on a plane before! The snacks and beverage offerings just kept coming. I enjoyed my warm meal. Entertainment offerings were good, and as we were on a newer plane the technology was better than other flights I’ve been on."
Cons: "Seats could have been a bit more comfortable and roomy, but they were decent and I didn’t have too much trouble sleeping."

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"

Pros: "Crew was nice"
Cons: "We were about 45 minutes late taking off so it was stressful for all of us that had a connecting flight."

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: "The customer agents were helpful and just great"
Cons: "That out of 4 agents and the manager one simple agent wasn’t as nice"

Cons: "We were told that those boarding and didn’t need carry on luggage. We went to do so and was told to get in line. When we got in line and up to go on plane, the person (a lady) told us we couldn’t."

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: "Crew was helpful and kind"
Cons: "Charge you for even instant coffee, the alla cart way of doing things is taking over the industry. all about making more money"

Cons: "Flight was delayed 30 mins to Dublin and flight was delayed 1 hour back to London. No free meals provided"

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

Pros: "Short smooth flight with unexpected food and drink service"
Cons: "Nothing"

Pros: "Great service as always"

Pros: "Nice flight personnel."
Cons: "Not even free water on the plane for an international flight! Can it get any more basic!?"

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"

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

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"

Pros: "Good to have movies to pass time on lng flight."
Cons: "2 days prior to returnflight I called stating the at was not enough time to catch a flight transfer having to go thru tsa again . B A assurred me I was o.k. ..It was not. A person should not have to physically run and have stress of wait to get thru TSA then run again back,get on train to next plane.Other passengers then said "ou are why we are starting late". It was a transfer off a plane from Ireland not a traffic issue. BA SHOULD HAVE PUT ME ON A LATER FLIGHT. TO SEATTLE."

Pros: "The snack provided onboard was tasty. The flight attendants took their job seriously."
Cons: "Southwest Airlines style seating with a foldable tray table over a middle seat. Sold as a business class cabin at a high price for an hour and a half flight but we left feeling ripped off. No boarding order and overall chaos boarding. I feel that for the price and being advertised as business class I was taken for a ride so to speak, and not in a good way. This would not qualify as business class on any other airline irregardless of how short the leg was."

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."

Pros: "Generally I like the staff at BA and they are mostly on time"

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."

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

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: "This was a connecting flight for us and was delayed causing us to miss our flight home from London to Los Angeles. There were no flights back to Los Angeles until the following morning (18 hours later). We had to stay in a hotel near the airport in the meantime. My boyfriend and I were forced to miss work an additional day causing stress and inconvenience to our lives."

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

Pros: "The boarding process was better than I expected in such a large plane. There were multiple lanes open to check in at the gate."
Cons: "The crew were not very attentive or polite when asked a question or for help. Then tended to go up and down the aisle with their carts with out stopping or offering anything and if someone asked them for a drink or something they would tell the, they would have to come back. The food on this trip was terrible and not well planned out. They ran out of the meat option for dinner before they were even halfway through the plane. At least 100 people had no food option. What was left was something with a cheese sauce cooked into it so it stunk with the foil was peeled back. I would have preferred the traditional peanut package to that."
