Pros: "Professional crew"
Cons: "I think for the price I paid for the flight there should at least be a free snack to go with the free drink."

Pros: "Professional crew"
Cons: "I think for the price I paid for the flight there should at least be a free snack to go with the free drink."
Pros: "Crew was very friendly and helpful. Entertainment had plenty of choices."
Cons: "The seats were very hard. It was very uncomfortable sitting that long I’m those seats"
Cons: "Terrible airline, they charge for everything, but don’t give the client good service. I was yelled by a worker because I was having difficulties scanning my bag at the self-scanning-and-uploading-your-luggage that you pay $100 dollars extra Per bag. I don’t like this airline."
Pros: "See previous note about lost bag."
Cons: "See previous note about lost bag."
Pros: "that there was a water and a blanket on each seat!"
Cons: "I thought there was free alcohol on international flights. that you were not allowed to use the given blanket until after take off."
Pros: "N/A"
Cons: "I was unable to make it to copenhagen due to missing my connection"
Pros: "Overall, an incredible experience!!!"
Cons: "The food was excellent"
Pros: "I have used Kayak for years without issue. This time I was flying SAS for the first time. The plane broke and so that was the first huge delay SAS had terrible customer service. They reminded me several times that I was not a preferred customer and that I had bought my ticket through kayak. This is the reason they gave for lack of help. It was frustrating to say the least. I’m not sure how they expect to gain repeat customers if they treat first time customers like that."
Cons: "I don’t like how the food on premium economy is packed in a cubic box that is really messy to eat from which the small plastic cutlery. Food quality is good, but feels like being an animal being fed from a bucket."
Pros: "Nothing."
Cons: "Everything. Our flight was delayed from our departing city because the plane was leaking water on the floor and they had to send in a special cleaning crew to try to stop it. We were not given the seats we pre picked months before when buying the ticket. The ac was broken for the first half of the flight. Then, we missed our connecting flight because of the first delay. Once we got onto a new connecting flight, it was also delayed and once again, we missed our last connecting flight and are not making it to our final destination today."
Cons: "Got asked to leave my seat in row 3 for one further back because I couldnt pull up my ticket mid flight to show it was my seat. Their system had me in another row so I missed out on the extra service offered to that row."
Pros: "Food was okay. Very smooth landing"
Cons: "Crew. One of the flight attendants was unfriendly and short when asked about food options. None of them were approachable."
Cons: "Tiny, hard, uncomfortable seats and cramped conditions, just about the worst 8 hours in my life"
Cons: "Rude crew, and apparently now you only get one free nonalcoholic drink in Economy for an 8 hour flight."
Pros: "Aisle seat"
Cons: "Nothing was complimentary"
Pros: "Easy boarding. Friendly staff"
Cons: "N/A"
Pros: "Not full. Kind crew."
Cons: "No complaints."
Cons: "This has nothing directly with SAS, but since I experienced it during my flight there, they are responsible of it. I was waiting for the flight at the OSLO airport waiting for the flight to LONDON. I had ample time to work on my computer. In the big room by the gate there was only one spot where I found three electrical sockets hanging from a pillar or post. To my dismay none worked. My plug would fall off from each. To document, I took the pictures of the useless sockets... I complained to the lady at the boarding desk (she left before the SAS staff moved in), she did not even care... This experience frustrated me and turned an otherwise pleasant trip into a bitter one. Please install some working sockets in your waiting room! Flight SK 809 Confirmation: LN9M6O Departure: Oslo & other airports (OSL) Arrival: Heathrow (LHR) Time: Sat Dec 2 2017 3:05 pm CET - Sat Dec 2 2017 4:25 pm GMT Peace, Edip Yuksel +1 520 481 1919"
Pros: "This is obviously a very well-run airline. Boarding was efficient, the crew were warm and professional, and the overall feel of the aircraft was very Scandinavian-cool. I was most impressed with the meal service. We were served twice on our 9 hour flight, and both meals were hot, healthy, and the best I’ve had during a flight. The passenger in front of us was having a hard time with her sinuses, and the flight attendant (whose name I wish we had gotten) was very attentive and concerned for the comfort and well-being of the passenger. She insisted on doing anything she could to alleviate the woman’s difficulty. It is clear that the crew care about the passengers’ experience."
Cons: "We were unable to sleep at all during our overnight flight and landed pretty exhausted. Our seats were comfortable (complete with a moldable headrest to keep your head from bobbing around) but we felt too upright to fall asleep. The passenger in front of us reclined, but we were concerned about reclining into the already tight space of the passenger behind us. So we weren’t able to sleep, despite trying to get comfortable/somewhat horizontal. It seemed to be a mixed bag of asleep and awake passengers on the flight, so some people were unaffected by this issue."
Pros: "On time, easy boarding"
Cons: "The flight was nearly full and everyone seemed to have at least two cases. This caused lots of jostling for space in the lockers"
Pros: "I was running late to my flight, and I found the SAS customer service line exceptionally helpful in helping me make the right decisions regarding how best to deal with the risk of missing my flight. In the end, I made my flight in time, but I found customer service critical in making the best decisions regarding my pre-flight transportation. Additionally, the flight was smooth and enjoyable."
Cons: "Nothing"
Pros: "Pleasant crew"
Cons: "Boarding was shambolic and the 737 is not as nice as the new A320 in terms of comfort or amenity. Boarding was all over the place - and the gate agents clearly need extra people around for a full flight. One person for 170 ppl didn't feel right."
Pros: "The crew was so amazing and friendly!!"
Cons: "Crew not very friendly."
Pros: "This wasn't a very long flight and I didn't eat or drink anything so there isn't really that much to say. But I can say that nothing was a problem at all"
Cons: "There were no problems"
Cons: "Unable to select seat/baggage until 22 hours before flight because not booked through SAS. Thought bagged was checked in online and had to pay More than the cost of the flight. Flight was delayed due to mechanical problem. Cabin very warm throughout flight."
Cons: "I was really disappointed at finding out at luggage check-in that I had to pay extra (£60.00) for my one regular-size suitcase. On the return flight I was told that this amount would be - as it turned out in my case - less than half, if I called SAS a day before departure. Why did I have to pay for the checked luggage at all?"
Pros: "Good leg room. Tasty meals. A good variety of entertainment options."
Pros: "Boarding was easy, I'm a Star Alliance Gold member so was able to get on board first. There were significant delays leaving Dulles and our connection was tight, but SAS held the flight so I give them props for that."
Cons: "The crew was grumpy and unhelpful, but I can usually overlook that. What really got me was this: YOU HAVE TO PAY FOR BEER & WINE ON THIS INTERNATIONAL FLIGHT! Never in my 25 years of international travel have I seen this from a mainstream carrier. For this fact alone, I will never fly this airline again. You also have to pay to pick your seats in advance."
Cons: "We paid over $75 for each piece of checked luggage. We could have saved 40% by pre-purchase but were not warned when purchasing our flights for almost the same price as the cost of the luggage."
Pros: "I had a window seat with a view of New York City as we flew North."
Cons: "The sound quality of the earphones was so poor that I could not understand most of the dialogue of the film that I watched."
Pros: "Good experience. Nothing extra-ordinary. Only complimentary tea, water and coffee."
Cons: "Flight arrived on time."
Pros: "The entertainment system was very good. The crew were all efficient and courteous, with the exception of one crew member who was rather curt."
Cons: "Our plane arrived at IAD late due to a minor mechanical that was repaired at its previous destination. Consequently, we departed IAD almost two hours late, causing us to miss our connection in Copenhagen. Norwegian Air had a flight leaving shortly from Copenhagen to Rome, but the transfer agent told us SAS "does not re-book with Norwegian." Instead we were assigned to two more flights, one to Brussels, and another from Brussels to Rome. We arrived in Rome around 17:00 rather than 10:35 as scheduled, losing a full day of sight-seeing."
Pros: "Friendly staff. Good food. Movie/tv options were excellent."
Cons: "Didn't like that I had to order vegetarian food option in advance. I would forget to do so before the flight. Despite that, I was still able to eat most of the meal since there was salad, bread and dessert which was filling enough."
Pros: "The food was very good surprisingly"
Cons: "Again the seats are too tight and they should not be allowed to recline"
Cons: "In-flight entertainment did not work, veggie meal I ordered was not there, and when I asked if I could have one of the extra business class meals, I was told no. I further asked if I could just have some chips from the snack basket and that was met with a death glare from the female flight attendant. All in all, the flight attendants were rude and unwilling to accept any ownership in the poor conditions of this 9 hour flight."
Pros: "Modern plane, great entertainment system"
Cons: "Paying for booze, vegetarian breakfast is awful."
Cons: "Out of all the staff on board they did not give me and a few others those blue customs form, so we made a huge line and when we got to the agent he told us we had to go all the way around fill one out and then come back. The attendants new that those were necessary why so many yet not one made sure we got them lousy service. I wish we got a crew that wasnt so insecure and cared more about providing a good service instead of caring so much over their appearance. I rather have good efficient staff what they look like doesnt matter to me."
Cons: "The plane was very old and not maintained well, dirty and not clean from the previous flights"
Pros: "Clean and good food."
Cons: "It was a fine flight. Nothing to worry about. I liked it."
Cons: "Seats are allowed to recline to far. When you are sitting behind someone who has reclined their seat you have no room"
Cons: "Unfriendly and rude desk help. Rude and insulting. United was a real disappointment. I will ask my travel agent to be in touch re screw up the economy plus seats. I had to pay extra for what our itinerant said had been booked. Mary, at the desk at C12 in Delles, she wouldn't give me her last name was unbelievably insulting and unhelpful."
Cons: "Too much meat in meals."
Pros: "Flight was fine, service good, and our seat choice excellent."
Cons: "We left an iPad on board in Copenhagen and found that there was no way to inform SAS!"
Cons: "No individual seat control of airflow. The plane was very warm and there were no vents at each seat."
Cons: "Not even one bag was included!! And to add a bag is extremely expensive!!! Paid five hundred dkk for one bag!!! Terrible service as well!!!"
Pros: "Easy embarkation, helpful staff."
Cons: "Shock to discover that suitcases were not included in price of tickets purchased online. We had to pay the equivalent of $100 (australian) per case. My seat was extremely u comfortable as the cusihion was misshapen. The male passengers seated behind us were drinking alcohol and became loud and garrulous, making the trip most uncomfortable and unpleasant."
Pros: "Flight was Ok"
Cons: "Left till last to board flight. Case taken from me. Asked continually when I wld be taken as I am 83 and recovering from major operation. Told 45 minutes before flight but was taken 10 minutes ahead. Rush has left me very upset."
Pros: "Old airplanes, no cellphone chargers, my monitor didn't work at all so they gave me an Iphad......"
Cons: "Old airplanes, you have to pay for alcohol...."
Cons: "Disorganization and unpreparedness."
Pros: "I liked the northern lights look after boarding upon introduction of the captain and crew members. Everyone was super personal and uninformed looked great. The best part was when they started boarding from the last row, which is the most logical and efficient way to do it"
Cons: "They forgot our vegetarian meal requests on both flights. Few drinks. Old movies."
Pros: "flight was fine."
Cons: "very disappointed Iceland Air is charging $95 for 1 piece of luggage. This is making me rethink the "deal" because it added $190 to the cost of the flight."
Pros: "Crew and food were amazing."
Cons: "It was perfect."
Pros: "Good crew and a smooth flight"
Cons: "Loudspeaker system lousy, could not hear any announcement from cocpit nor cabin crew about safety or flight progress"
Pros: "Cabin crew was very nice."
Cons: "No food was served for an international flight. This isn’t a budget airline."
Pros: "Seats were very uncomfortable (economy), cabin was smelling urinal, flight was full, just the thought to go to the amazing country kept us (4 of us) encouraged."
Cons: "Seat comfort for six (6) hours flight could be better"
Cons: "It was so HOT in our original row (13). The woman next to us passed out, no doubt because of how uncomfortably hot it was"
Pros: "Crew was friendly."
Cons: "During the flight many people (including myself) complained about the very cold temperature setting inside the cabin. Passengers who asked for a second blanket did not get any. Unfortunately, the crew never switched on the heating system in order to make the flight comfortable for most passengers."
Cons: "Agents went out of their way so my wife and I could sit together. Thanks so much!"
Pros: "Connection gate in Rekyaveck wa. Sry convenient"
Cons: "Seat comfort for a new plane was terrible"
Pros: "Paid extra for legroom, but sadly the seat did not recline much due to being in row at the emergency exit"
Cons: "Seats are uncomfortable and better entertainment"
Pros: "ease of boarding, the flight left Dulles at the perfect time, after all the crowds were gone"
Pros: "I like that they give a pillow and blanket on the plane. I also like that from Dulles to reyjavik they gave us a bottle of water."
Cons: "The boarding process is a bit confusing and not well organized compared to other airlines. They should give a bottle of water every flight."
Cons: "Our plane was broken. Initially they said an hour late and then the time before our flight increased. Because our flight was delayed, I missed I missed an important meeting."
Cons: "Flight labeled Economy but actually Economy Light, which meant no baggage. Just Fly didn’tt Show that."
Cons: "Every flight on Icelandair that I had, was delayed. Very slow check in assistance. Ground crew were not friendly nor helpful. They would push and shove anyone in their way, instead of saying “excuse me”. Paying for ONE check in bag should not be $95. Most airlines charge between $20-50 for the first bag. Also no snacks for a long flight."
Cons: "the delay starting in DC, followed by more delay on the tarmac in Reykjavik, and followed by long waiting for the bus to get paasengers to the airplane in Reykjavik"
Cons: "The seat I was in did not recline and the flight attendant was not able to assist me with moving to another seat. This was terrible considering it was a 7+ hour flight ..."
Pros: "It was the fastest route from Washington DC to Helsinki."
Cons: "Staff a bit cold (no pun intended). Aircraft are well maintained but old. Business class is not at all on par with the competition. It's called premium economy on every other airline. Outdoor disembarking and boarding in Iceland... Yes, it's true... Even with open gates at the airport. Contrary to the staff, passport control is in Keflavik... With the one hour layover... Expect to be stressed trying to make your connection. No partner airlines means no credit for using this airline. Overall... Unless I'm going to Iceland, I think I'll forego using this airline in the future. Rather be in another carrier's premium economy than their business class."
Cons: "Flight was more than one hour late"
Pros: "I need a cheap flight and at the time that was my best bet. Didn't have a bad time but next time I will fly direct from the US."
Cons: "Seats were so so, leg room was barely substantial. Iceland is expensive even on a layover, thankfully it wasn't very long."
Pros: "Not a single movie was offered with captioning for those of us who hate ear buds or with hearing disabilities or who prefer to watch "quietly". Many of these have already been captioned elsewhere at another time so what's with not bringing to captions along?"
Cons: "Desk agent asked if we were willing to sit in exit row. We agreed. Seat assignment turned out to be next row forward so we were unable to recline for a 5 hour red-eye."
Pros: "I was able to get a good seat just behind the first class section."
Cons: "There's no free food . They should give at least snacks like sandwiches, peanuts, etc."
Pros: "I had no idea that no meal would be served on the flight. Ended up buying a salad that was so so. Not a wide selection. Missed on breakfast altogether on my next fligh. Wasn't asked if I wanted anything. Thought it was only coffee or tea."
Cons: "Good options and uncomfortable- no pillow provided or offered. Perhaps I should have asked?"
Pros: "Great service and comfort on this flight. Reykjavik airport is not comfortable at the gates--disorganized and nowhere to sit--but that's not Norwegian's fault. Good experience with Norwegian Air!"
Pros: "Good entertainment options and device charging."
Cons: "No meal. One drink."
Pros: "The Icelandair ground staff tried their best to deal with the impossible but the end result was still totally unacceptable. See below for details."
Cons: "Incompetent ground operations. Five departure delays and gate changes. 24 hour delay. Communications and customer service disaster."
Pros: "Staff on plane."
Cons: "Hardest and narrowest seats I've ever experienced. No complementary food served on transatlantic flight and the food offered for sale was unappealing and expensive. There was a problem with staff meeting the arriving plane to open the door and allow passengers to disembark. The wait was 15 minutes for someone to show up on each leg of the trip."
Pros: "There is good legroom, and hip room. Crew is very pleasant and react promptly. You have a nice entertainment system - if you remember your headphones."
Cons: "No food on a long flight - not even a bag of pretzels. If you forget headphones you have to buy them, whereas other airlines offer them for free."
Pros: "The crew were very friendly and helpful. Also our flight from DC arrived late, the connecting flight waited."
Cons: "My suitcase did not arrive (which was to be expected as we arrived late), but it did not arrive 24 hours later either. No food was served, not even a small snack. Boarding was slow and it was hard to hear the announcements. (Maybe this is an airport issue)."
Pros: "Boarding was organized and efficient. Made sense to do it from the rear of the plane forward, by rows. Flight attnendants courteous and very helpful. Pillow/blanket/multiple non-alcoholic beverage services. Limited but adequate movie/tv selection. I watched all the Icelandair Iceland travel specials instead--highly recommend. We were delayed 20 mins leaving as the incoming flight was late but we made up the time in the air. Minimal/unobtrusive cockpit announcements. Very nice red eye flight."
Pros: "I was the first one off the plane"
Cons: "The emergency door was in front of my seat. I couldn't sit without my knees hitting it or at an angle which is uncomfortable. I asked the flight attendants if I could I've and they said "no it's a different class". I paid for a seat on your airline and all I wanted was that seat but was given something Waltham was not what I paid for. Also, I had to hold my water bottle and book bc there was no seat back pocket. It was a miserable flight. Especially since the gentleman on the other side of the plane in front of the emerge door was able to move to one of the seats that, "was a different class". I guess just a different class for me??"
Cons: "I was surprised that we did not get a meal service, not even a little snack for a long hall, from D.C. to Iceland. The only service we had was the water. I probably won't fly with this airline again....Sorry."
Cons: "Reykjavik airport was cramped, with no good food options behind security. Would not bring my stroller to me; they did have (broken) strollers for common use, but I didn't get my stroller until IAD baggage claim (and it was soaking wet). So I had to go through the haul to immigration line with no stroller."
Pros: "We really loved the price and the service was fine. Having the stopover in Iceland on our way to England was a treat and the schedule was fine."
Cons: "Bugged me that they charged for a meal on an intercontinental flight."
Pros: "Crew were polite, though they didn't hand pillows and blankets out to everyone. I declined a blanket, since I had one from the first flight, but was never offered a pillow, which I would have accepted. The style of this plane provided a ton of head space, which was really nice."
Cons: "The seats were really uncomfortable for such a long flight. Also, the entertainment system was having trouble for half the flight before they finally fixed it."
Pros: "Flight was cheapest option for a family of 6. We had mechanical issues prior to leaving DC and missed our connecting flight. Icelandair did a great job in putting us in a hotel and providing free transportation to and from the airport. Reykjavik is a beautiful city and we made the best of the layover. We plan to come back to Iceland for a longer visit to explore more."
Cons: "Next time I would plan for a stop over-- it seemed to run so smoothly that it must of happened often. We lost a day in Paris due to the delay which we were disappointed in and they did nothing for our lost hotel day that was paid for."
Cons: "Our flight from Washington DC to Iceland was so late that we lost a day of our vacation and had to spend three hours in line at the airport to get hotel vouchers."
Pros: "Comfortable, clean, and affordable! Clever descriptions about the airline and Iceland, which was a great addition to the vibe. Would definitely fly with them again, and recommend. FYI - They save money by not serving meals on the flight, but that's not a loss."
Cons: "Loved it."
Cons: "Flight was almost an hour late departing IAD, and arrived too late in Reykjavik for us to make our connecting flight to Paris, which Icelandair did not hold at all for the many passengers who were connecting. We were sent to England, then connected with another airline after a four hour layover. Our arrival in Paris was 8 hours late, and our bags did not get to us at our hotel until four days later. This was poor customer service by Icelandair all around, that could have been avoided by holding the connecting flight for 45 minutes. It affected many passengers, not just us."
Pros: "International flight no food could not believe"
Cons: "Seats were smaller than other"
Pros: "Exit row seating was comfortable with plenty of legroom."
Cons: "Delayed flight with no communication from boarding gate. Knew about delay from Kayak hours before we heard about it at the airport."
Pros: "Entertainment system"
Cons: "No food, beverage service very limited."
Cons: "Did not realize that free meals were not provided. The trip ended without eating for 9 hours, as no hot meals were offered."
Cons: "Boarding/departure was 30 min late. Sat in the back of the plane - the stench coming from the bathroom was nearly vomit-inducing."
Pros: "Crew was friendly, flight was good"
Cons: "The seats on our plane were the worst seats of my experience EVER. When you have to be seated for 5+ hours, some level of comfort is required. I could barely stand by the time we got to Iceland. NEVER again. I'm not usually picky but this was ridiculous"
Cons: "No food on either flight. First flight was 20 minutes late, which made our one-hour layover very stressful. We asked the Icelandair woman at the gate if our bags made it even though our layover was short and she seemed annoyed by the question, and said "Yes. All the time." Our bags did not make it, and it took an hour and a half after waiting for our nonexistent bags for 30 minutes to report them as missing, as there were two employees in the office for 30 people whose bags didn't make it."
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: "Comfortable, good food and good crew"
Pros: "Seating and leg room much better than Ryan Air!"
Pros: "It was short and with friendly staff."
Cons: "No complimentary refreshments."
Pros: "Everything except the food"
Cons: "The food."
Pros: "Good food"
Cons: "We arrived late to Dublin because of weather and we’re going to miss our connection to Leeds so they rerouted us via Manchester but our bags, though tagged “Rush” did not make it on the new flight and we were without them for five days! we still had to get to Leeds so we had to pay for train tickets"
Cons: "Best flight I have ever been on"
Pros: "Good seats. Friendly crew. They were late serving the breakfast snack, must have not been watching the time, but it made me chuckle."
Cons: "The check-in at Washington Dulles was understaffed. Boarding was chaotic."
Cons: "Late - again!"
Pros: "Crew was amazing, someone had found my passport and turned it in to a crew member."
Cons: "Nothing"
Pros: "Check in was a breeze with all so helpful. Cabin crew very pleasant. Very comfortable on time flight."
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: "I had a 5 hour delay. I had to cancel the trip"
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: "On time"
Cons: "We had to spend $1000 on tickets because Kayak DID NOT book us on the flight we had a confirmation for"
Pros: "Almost everything was good. Friendly crew, easy boarding, safe flight even with lots of air gusts (thanks to the pilots!)."
Cons: "Whatever fare Kayak provided was the worst seat (last row next to bathrooms). I wouldn't book through Kayak again and instead would go through the airline directly."
Pros: "Blankets and earphones provided."
Cons: "Couldn’t checkin at British Airways; there needs to be better signage at desk. Flight was delayed and we almost missed connection. Seat would not tilt back."
Pros: "The crew were very professional and courteous"
Cons: "No USB ports and no way to plug in one's personal earbuds. Sounds quality on the airline supplied earbuds was horrible. Gave up on the entertainment offerings and watched movies I had stored on my iPad. And really the worst food I've ever had on a flight."
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: "Could not check in on-line from Dublin on either Air canada or Aer Linguis websites. Time to sort out this long-standing problem"
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."
Pros: "Seats and service was excellent. Flight was on time and very organized."
Cons: "Nothing"
Pros: "Was part of my international flight"
Cons: "Was part of my international flight"
Pros: "Goo entertainment on Dulles Dublin sector."
Cons: "It would help if ba would hilight fact that this is a code share with are linguistic. Seat were unbelievably small and had to walk to ends of earth for both the gate in Dulles and Dublin. No free food or drink on Dublin madrid sector but thankfully not full so I could stretch out. New planes on both sectors."
Pros: "Ahead is schedule"
Cons: "Even had to pay for coffee"
Pros: "short and uneventful...friendly staff!"
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: "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"
Pros: "Crew on board were very nice and very helpful.Apart from that I am struggling to see how this is a 4 star airline. It's a joke"
Cons: "AerLingus use a Boeing757 on this route and the seats are old, uncomfortable and many have dips in them.The entertainment system is ancient and had limited stuff on it. The food was as bad as airplane food gets. The 'beef' Shepard pie was lumpy and over salted. Also you must pay for beer and wine on this 4 star airline. They use "smart flies aer Lingus " as their advert tag line. In my opinion smart flies someone else"
Cons: "Bags got delayed by a day."
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: "The in-flight experience and service."
Cons: "The fact that my luggage did not initially transfer from the first leg of my trip to the second leg of my trip. I received my luggage by the end of the day, but it was somewhat inconvenient to not have a lot of my personal effects for several hours."
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!!"
Cons: "Added 12 hours to my trip and had to rebook on another airline for the second leg. The crew was unapologetic after sitting on the tarmac for three hours. Terrible airline"
Cons: "You can't get a seat assignment until you check in at the airport. I ended up in the very back row, right in front of the galley for a 7 hour flight. No sleep for me."
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: "I'm soooo upset about the service after my flight canceled. 1.the staff ignored me when I asked if I could have a VIP to rebook my tickets earlier because my mom got cancel and was going to do the surge . But he went away and never came back, no any response of YES or NO. 2.I don't know why the airline company still need 11 hours to rebook the tickets with all our flight information and our passport liscen numbers already , making us waiting till 3 am at the airport. 3. I asked my boyfriend to talk to the staff on phone, and the staff told my BF that he didn't know my English was not good. I said to him loudly that I had told him , but the manager besides said "don't shout at my staff"to me, even without asking me what happened . I don't think that was a good attitude for the service department, especially to a foreigner. My email address is Chentongtong@wku.edu.cn"
Cons: "Seat 31A: Headphone socket was not working properly, table was broken (didnt keep the food tablet), entertainment system crashed after pausing the movie. check-in baggage was lost during journey and still couldnt get found. Very annoying."
Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"
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."

Overbooked flight which led to big delay.

I didn't know anything about TAP Air Portugal but the flight was awesome and far cheaper than any other airline.

Awesome crew. Zero turbulence

Great airline, took good care of us. Will use again if prices are good. Really enjoyed the 24 hr layover in Lisbon.

Pros: "Good"
Cons: "Good"
Pros: "The crew."
Cons: "Fake marketing! They said it will be some snacks for economyXtra, and then 2 hours before the flight sending an email saying that the snakes will be charged! Disappointed!"
Cons: "I paid Xtraeconomy to have some snacks during the fly, and they end up coming with a trolley to pay! Disappointed!"
Pros: "Smooth flight"
Cons: "More food, more water"
Pros: "The crew were very nice overall but one flight attendant in particular was incredible. I didn’t get a name but he was friendly, welcoming, and kind."
Cons: "I sat in an emergency row with an empty seat to my left and really did not like how the passenger in the row behind me kept getting up and walking into my row to get his stuff from the bins."
Pros: "Sleeping and being left alone"
Cons: "Food, Service by cabin crew because they never smiled"
Pros: "The flat bed"
Cons: "The Captain made loud announcements waking you up"
Pros: "Amazing punctuality, both on the way out to Lisbon and on the return to London."
Cons: "Cannot really think of anything that needed attention on these flights."
Pros: "I didn’t like a thing. The crew from the gate all the way to the end was rude and nasty. The crew scanning people to get on the plane were so rude at the beginning it was the worst and I fly for my work and I’ll never fly TAP air Portugal again."
Cons: "Train the staff to be nice and pleasant"
Pros: "Yes"
Pros: "Super friendly"
Cons: "Maybe a hot meal?"
Pros: "Quick. Smooth!"
Cons: "Probably the most uncomfortable flight I have taken in a very very long time. The ride was smooth but the seat was so terribly uncomfortable. I was in pain on arrival."
Cons: "We had to pay $120 for a checked bag because it “weighed too much”. The lady at the check in counter said they were weighing everyone’s at the gate so there was no way to get around it This however was a lie and they were not checking weight and people got on without having to pay the outrageous fee"
Cons: "So many delays, no real info provided. When we had to stay overnight they didn’t mention it would take 4 hours to get our bags which actually never came. Airline industry sucks and deltas one of the worst."
Pros: "The only salvation was the entertainment choices. ."
Cons: "The planes need to upgrade the seats. When we were served food if the person push their seat back your food tray would flip like two did on our flight. Staff was jaded and sarcastic. I'm glad I had a discounted flight. I'd be angry if I paid full price. Poor staff, seat architecture, and poor food."
Cons: "Not cancelling it"
Pros: "flight was more than 4 hours late!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Cons: "flight was more than 4 hours late!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Pros: "Very on time, smooth take off and landing and friendly staff."
Cons: "Perhaps spirits offered other than just wine. And a vegetarian food option."
Cons: "Passport control in Lisbon was awful and many people missed their flight in spite of them being made aware of the issue."
Pros: "clean and fast"
Cons: "use airport finger in Lisbon airport"
Pros: "Nothing!!!"
Cons: "Paid thousands of dollars for this trip and my luggage is missing as tap Portugal convinently lost it."
Cons: "at check-in agent said we did not have coverage on our ticket for our 2 -50lb bags dispite informing her that we were covered and had no problem on our arriving flight to Portugal - we had to pay 196 Euros or leave our bags in Portugal Additionally we had ordered a wheelchair to assist my wife to the gate - which we also had our arriving flight - agent said she had no record of it. She said we could wait which we did and waited 2 hours to obtain a wheelchair (and came close to missing our plane) not to mention the stress associated with the whole check in process"
Pros: "Nothing"
Cons: "Everything"
Pros: "Surprised and delighted to be served a tasty sandwich and fruit drink plus glass of wine on a 3 pm 2 + hr flight from Lisbon to London"
Cons: "Seats uncomfortable"
Pros: "Clean modern aircraft"
Cons: "Left 35 minutes late; had to take a bus to the plane in Lisbon (no gate)"
Pros: "The crew did a great job."
Cons: "The boarding process was nutz. We had to take a bus away from the terminal to board the plane. The flight was delayed. I was not very happy to have to spend $92 to check 2 bags."
Pros: "Flight on time and safe Crew very pleasant"
Cons: "Cramped seating Boarding dreadfully slow"
Pros: "the food , drink and the crew"
Cons: "seats not very comfortable. plane full up"
Cons: "We booked flight several months ago and it included seating assignment, so we choose our seats. Then when we check-in they had changed them to the last row of the plane. We had received a couple of emails asking for us for option to pay for advance seating. Assume they had changed their policy and now were charging. We had a close connection at LHR and being last off, we almost missed connection. Horrible"
Cons: "The delay on the take off"
Cons: "We had to postpone our first leg from London to Lisbon by a day and then they cancelled our return flight without telling us!!! So, we were trapped in Lisbon with no flight to return home. We called them and they said, "we cancelled your tickets and only have business class seats available for you and your toddler." We said no thank you. If we were going to spend 1k on a return flight, we were going to take British Airways. TAP, never again."
Cons: "The service was below average, nobody seems to be eager to assist. The food that was offered on the flight was below expectations. The company should work on improving customer care"
Cons: "No vegetarian option The last seats mean can't lean backwards when someone in front goes backwards :("
Cons: "The delay which caused us to miss our connecting flight and as a result being stranded at the Lisbon airport for 6+ hrs. This would have been avoided if there was proper communication within the airline-- an absolutely irresponsible way to handle our plight. The ground personnel themselves admitted that no one informed them of our arrival time. True or false? go figure.This all occured while they refused to allow us on board our plane that was still at the gate and nowhere near taking off. This also resulted in rescheduling our ground transfer, which resulted in additional expense. Overall, a nightmare of an airline. Avoid."
Pros: "Crew friendliness and attention"
Cons: "They ran out of diet coke and coke zero literally right after takeoff which is a joke!"
Pros: "I was very impressed with the Ground crew who met me off the plane and had already arranged for me to go on a later flight with Emirates. If it had been possible to let me know when I was on the first flight that my onward travel had been arranged then it would have been perfect."
Cons: "my TAP Portugal flight from Lisbon to Heathrow was so late I missed my connection to AbuDhabi."
Cons: "The lady changed my 11H seat for another seat (29B) when I claim that this is not fear , a man said to me that if I insist in this matter he will not let me in Or flight , for me this was an abuse"
Pros: "Everything was perfect! The staff was friendly and the food was nice. I found that there was more leg room than on other airlines."
Cons: "I used TAP to depart beautiful Portugal."
Pros: "Not enough leg room"
Pros: "Not much. Lunch"
Cons: "We paid to check the bag In and when we arrived the girl could not see this. We showed her clearly the paper then she charged ya and realised she had made a mistake but couldn't refund us. Terrible experience. Don't use the."
Pros: "Great flying as always. Best leg room anywhere."
Cons: "On flight food."
Pros: "Flights were on-time, planes were clean/newer, snacks were good."
Pros: "The flight was fine, no issues. Plane was fine, no WIFI or entertainment. Served a small meal. For the price, excellent trip."
Cons: "All was good."
Pros: "This is the third time I fly with TAP and they are always late. Plane seats have zero legroom. TAP staff are not friendly and seem uncaring for the most part. If possible, I will not fly that airline again."
Cons: "My TAP flight from Lisbon to Madeira island was 2 hours late arriving so I lost all of my flight connections back to Boston and San Francisco. I was stuck in Lisbon Portugal for one extra day - was told to get out of the airport, then asked a bunch of people what to do, finally got in a very long line of people within a very hectic and loud airport full of travelers. 60+ people in a line being helped by only 2 rude counter staff. I waited in TAP member services line for 2 hrs and 30 minutes. They gave me a voucher to a motel and a taxi cab where I would have to spend the night. On my way back, I was diverted form Boston to Miami and the whole ordeal was unpleasant. It seems like TAP staff doesn't care about inconveniencing passengers. I overhead a conversation between a young 30+ year old TAP male staff wearing a dark blue sweater and dark blue pants belittling a British woman passenger. While waiting in line I was surprised to see how rude the counter TAP staff were to passengers who were frustrated that they lost their flight connections because of the TAP plane's late arrival. IF possible, I would never fly TAP again."
Pros: "No comment on this flight"
Cons: "No comment on this flight"
