Airline reviews

Cons: "On the Copenhagen-Milan leg, since I was in the cheap seats, even water cost; $3 for a bottle of water. They couldn't even offer a cup of water for free? False economy. And I was told that I had to pay for my luggage at the airport, then it was $120 for 1 bag. Ridiculous!"

Pros: "Excellent and professional crew members"
Cons: "Nothing, the flight was smooth, most enjoyable"

Pros: "Clean and very good stewardesses"

Pros: "On time travel. Check In Staff were kind and engaging."
Cons: "On flight staff were minimally attentive. Food was mediocre."

Cons: "The food offering"

Cons: "Food was pretty atrocious. Before having this flight I tried many times to book a special meal but their website is nearly impossible to use. So on the flight I was given two options of fish or mexican beef. Mexican beef meant slow cooked beef in a salty brown sauce with 2 kidney beans. Yes 2 kidney beans. With potatoes carrots and broccoli. Entertainment was pretty lacking. Not a lot of options. Also it was freezing the entire flight."

Cons: "Flight to Stockholm was cancelled. SAS Provided no informaton on the steps for re-scheduling my flight. I had to call the SAS headquarters in Stockholm before receiving any guidance on what to do next. All service attendants ditched the ticketing desk leaving one poor employee to answer questions for over 70 disgruntled passengers. Very very very poor communication. Luckily I was finally able to book a flight using another airline after waiting on hold for 20 minutes with the regional customer service provider."

Pros: "The staff and other guests are always so polite! Getting the SAS Lounge Pass is always smart."

Pros: "People were very kind. The food was terrific!"
Cons: "The entertainment system was slow."

Pros: "Aisle seat"
Cons: "Nothing was complimentary"

Pros: "Very comfortable and smooth flight, on board entertainment on first leg of trip was great. Food was fresh and good. Nice coffee & Tea service,"
Cons: "Boarding was a little scattered, but ok"

Pros: "Easy boarding. Friendly staff"
Cons: "N/A"

Pros: "One crew member was particularly nice and personable."
Cons: "We waited an hour in the plane before take-off and after boarding, during which time the crew deliberately filled the cabin icecold air thick with the highly toxic fumes from the deicing. I got a headache from it. Throughout the process the entertainment units were disabled, when they could have helped distract passengers from this ordeal. The food was disgusting. When the Danish government has repatedly bailed out SAS, it would make a lot more sense for everyone involved to have higher quality Danish products on board for the meals, especially for such things as dairy products."

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: "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: "All went well !! On time friendly staff ."

Cons: "They only offered tea and coffee for free as a drink and nothing anything more, and were not kind at explaining this."

Pros: "Crew were excellent, had a row to myself, luggage turned up quickly"
Cons: "No landing cards given!"

Cons: "Food was really, really bad. Only one very bad choice ignoring health conditions of different passengers."

Pros: "The flight attendants were very nice and on the cross continent part of our flight we had dinner and breakfast served. Lots of leg room."

Pros: "Flight was on time and the crew was effcicient"
Cons: "My knees hit the sear in front of m before they recloined. No way to sleep."

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."

Pros: "We were eventually rebooked in the class we paid for."
Cons: "Our flight was cancelled with no notice. We were rebooked in economy class when we paid over $5,000 for business class tickets, and told we would "probably" receive a refund for the difference. after much prodding, asking and begging, we were finally rebooked in a flight on Lufthansa the same night. That airline was upset, though, because SAS did not call them or notify them that we had been switched to their airline."

Cons: "Water and beer paying"

Pros: "The food was very good surprisingly"
Cons: "Again the seats are too tight and they should not be allowed to recline"

Pros: "Upgraded 2 biz 4 reasonable $, everything great"

Pros: "Everything was great"
Cons: "Nothing to mention"

Pros: "Comfortable flight, friendly crew. Would fly again!"
Cons: "Food could have been better"

Cons: "I did not like my flight because ... I could not take it! I needed to change only one date (return) and was quoted $1300 for that one change. Getting a completely new ticket was cheaper, but not cheap. With such cost of even minor changes, next time I will look into booking directly with airlines, instead of Kayak; sorry to say that, as I really liked using your service."

Pros: "Nothing at all"
Cons: "Fight was canceled and no email or communication was possible with this company. Called SAS office - CLOSED. Stood in line for 2 hours and no one came or announced anything. Checkin agents were on dope-no help and checking machines not working!"

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."

Pros: "Excellent meal and very friendly staff."
Cons: "The cabin temperature seemed pretty warm."

Pros: "Comfy and good movies!"

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!!!"

Cons: "Not enough room to work on laptop."

Pros: "Easy flight, nice crew members, no issues had here"
Cons: "My luggage didn't show up for five days of a 7 day trip from a direct flight! SAS was completely useless by phone, email, and Facebook.... They set up a phone line that nobody monitors and had my luggage in-country for days before even sending someone to deliver it"

Pros: "12 people got bumped!"

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: "Wonderful service! Flight attendants kind and thoughtful. Once in terminal 5 (from terminal 1) a Sas gate agent escorted us to flight since our previous United flight was so late"

Pros: "The flight crew (flight attendants are the best I've encountered in terms of tone and hospitality) cleanliness, the food, frequent offers of water, your own TV and numerous options for entertainment and ability to track flight"
Cons: "Like the sleek style but still wish there was a little more leg room"

Cons: "Miserable cramped seating ."

Cons: "1st class could not board because that area was not cleaned"

Cons: "Disorganization and unpreparedness."

Pros: "Overall, the flight was good. As always, I like SAS's service. Crew are friendly and accommodating."
Cons: "When waiting to board the flight, it was difficult to understand when different parts of the plane were boarding because of the soft volume of the loud speakers. All people could really hear was "boarding now", which created a bit of a rush of everyone. It would be helpful if there were an SAS representative to stand next to the line, to physically say to people, 'Okay, we are now only doing priority boarding. If you are priority boarding, please stand her. After that, if you are business class, please stand here. Everyone else, please wait, but know that we will start to board from the back of the plane. Thank you." This will to help guide people BEFORE the ticket check."

Pros: "Flight was fine, cr"

Pros: "Same as above"
Cons: "Same as above"

Pros: "Free upgrade to SAS Plus, what's not to like!"

Pros: "The Plus Seating was really good"

Pros: "Thanks to the staff while checking in my luggage I was able to check my bags directly from Stockholm to Mexico City via preventing me to loose a lot of time in London where I was supposed to check in and out because I purchased my trilp in two different segments"

Cons: "When you book BA and end up with Iberia, that’s definitely not what you want..."

Cons: "My checked bag did not make it to London, and it’s really affected my short stay which requires a lot of traveling around England."

Pros: "The aircraft comfort"
Cons: "Do the checking before not 15 min before the departure"

Cons: "Delayed by an hour due to inbound delay, causing a knock-on delay with plane maintenance. While fairly comfortably seated and offered water, this still was somewhat unpleasant especially after a long-haul from Havana"

Pros: "Good was decent. Didn’t need to schlep big bag of snacks."
Cons: "Turbulence lasted way too long. Probably out of their control but I wondered if they could have changed altitudes."

Pros: "Not a lot."
Cons: "Arriving at the gate whilst the flight was still boarding, with a boarding pass in my hand, and being told that my seat had been given to someone else because the Airline unilaterally decided that my connecting flight from Bogotá would not arrive in time. Followed by two hours of Iberia staff being surly, not looking me in they eye and doing absolutely nothing about getting me home. I have now been travelling for nearly 30 hours without sleep, am stuck in Madrid with no certainty of when or how I will get home or see my luggage again, and am seriously seriously pissed off. I do accept that things can sometimes go wrong and that it is nobody’s fault. This is definitely somebody’s fault."

Pros: "Every thing was ok"
Cons: "N/A"

Pros: "The food was nice."
Cons: "There was no water in business class toilets. The staff are not polite."

Cons: "I was not able to check in online"

Pros: "The screens on a dozen seats just failed a few hours in - engineering issue. And breakfast was a cold pretzel. Food gets let’s generous on BA all the time. The crew were lovely."
Cons: "A 2330 Flight ran significantly late with a passenger delay and then de-icing. The repeated assurances of “a 10 minute or so delay” were obviously not correct. Takeoff close to 0100 was followed by drinks AND then food - my vote would be neither. Please oh please just let us sleep."

Pros: "The business class seat was extremely comfortable."
Cons: "The touch-screen was very difficult to navigate. It didn't respond very well when touched."

Cons: "Seating and not so friendly"

Pros: "Heathrow Airport has a lot of stores to keep you occupied"
Cons: "Late notice of where our gate was located. By the time we got the news, we went to our gate and the people were already boarding"

Pros: "Airbus 320"
Cons: "Boarding process and pitiful legroom space . Iberia clearly loves showing the privileged few who have paid top dollars to be at the front , that we must be made to wait and struggle to get to our seats .Then, we have to squeeze into a tiny , pitiful space of a seat .....Even Ryanair does better !"

Pros: "seat is comfort"

Pros: "Flight was safe, aircraft was clean and luckily with enough room under the seat to store carry on bag"
Cons: "The fact that all the passengers boarding in "group 3" were forced to check in their carry-on bags if they did not fit under the seat; and retrieve those at the baggage claim area (not right after exiting the airplane) In my case I was able to store my carryon under the seat in front of me after pleading to the crew and gate members to let me try because of my connecting flights. There is no complimentary food service, even water is charged."

Cons: "I was Given different seat at boarding into less comfortable place - no explanation."

Pros: "Philadelphia to London"

Cons: "Mistake Kayak or its subcontractor made in listing the name of my wife incorrectly. This created a real hassle in getting a boarding pass in her name"

Cons: "Missed connection from Chicago. International connections need more time to complete"

Cons: "Our luggage did not arrive. They told us it was sent to another city by mistake and that they would get it to us as soon as it arrived. It's a long story but we didn't get the bag for a week. We called multiple times and got very little help. We finally got the bag, but had to buy new clothes to get by in the meantime."

Cons: "No ability to do online checkin both websites were not working."

Pros: "I am of average height -6 feet- and my knees were touching the seat in front of me. Not comfortable but not too bad either."
Cons: "Boarding was extremely chaotic."

Pros: "Nothing"
Cons: "Doctor recommended not to travel but no credit given."

Cons: "There was no complimentary water or beverages"

Cons: "Very pleased with overall service and hospitality"

Pros: "Movies were good, seats were OK"
Cons: "Paying $85 for a 2nd bag"

Cons: "Upon boarding the aircraft was really hot, I was sweating in my seat... I did not receive any complementary drinks or snacks."

Pros: "Movies, no delays"
Cons: "Luggage was not documented correctly to my final destination by Iberia"

Cons: "Very limited room to move. Rather impersonal"

Pros: "Comfortable flights & on time"
Cons: "Service, flight crew seemed to busy chatting instead of serving."

Pros: "Nothing"
Cons: "No free snacks or drinks"

Pros: "The crew were friendly and helpful."
Cons: "I think the Brie cheese I ate made me sick afterward. I wish the staff had brought water around more."

Cons: "It was cancelled and stranded me in Chicago.I will never use Iberia again."

Pros: "The ease at putting my luggage in.."
Cons: "The prices of the food and drinks!! Ripped off!!"

Pros: "Alcohol allowed for free. Friendly people"

Pros: "We were overall very pleased with everything about, thank you!"

Pros: "The crew was fabulous! And the ride was on time and had plenty of entertainment."
Cons: "My only complaint is that the seats were very tight in the economy class. We were packed like cattle. I know these were the "cheap" seats but for almost $1500 I would hope for a bit more comfort."

Pros: "Nothing"
Cons: "Kept us waiting for five hours"

Cons: "Late departure."

Cons: "The seat did not recline, a bit ridiculous for a plane that size"

Cons: "I have to say with all sincerity that my pre travel experience was horrible. Two day before my flight I got an email saying my flight had changed. Over the next 2 days I spend 7 hours on the phone with Vamaya, Iberia and Finnair and no one could seem to help me. The story always changed and I was given crazy false information. I was even told my flight was changed to 8pm on departure date when it actually was leaving at 4:40 pm. I am glad I got to the airport early. I had to to deal with all my problems. In 30 years of travel I have never had an experience so frustration. I would love to speak to someone at Kayak."

Pros: "No delayed flights"

Cons: "The fight from Chicago to London was a nightmare."

Pros: "All airplane attendants were very helpful and always on the call."

Pros: "Loved the gluten free meal option."

Pros: "It is always a pleasure to fly in this Iberia company"

Pros: "Spaciousness of aircraft, comfort of aircraft (vibration, noise)"

Pros: "Ok"
Cons: "No problems"

Pros: "The crew was attentive but only on the basic standard service."
Cons: "I truly love that there are very few travelers. Also, I went through a lot getting to have done a covid test in order to travel, no one asked for it! Also when filling the custom forms they could have been and explain that one paper form was enough for a whole family"

Pros: "Flight was on time. Seats were comfortable. Plenty of food was included in the flight. And service was good."
Cons: "Greater weight allowance for carry-on luggage."

Cons: "Customer service from the crew, it could be nicer and better attitude and more positive."

Pros: "The lady checking me in was nice"
Cons: "Items were stolen from my bag"

Pros: "Efficient check in and polite crew."

Cons: "Grab business class upgrade offer - worth every penny."

Cons: "Maybe have one flight be on time. Train ground crew how to put on fuel."

Pros: "Good entertainment, great price"
Cons: "Had about 30 people on our flight that was taking another TAP connecting flight - missed the gate by less than two minutes - did not hold the plane when they could have"

Pros: "I liked that pillows, blankets and headphones were provided."
Cons: "Boarding was a cluster (mainly because the lines were unorganized)."

Pros: "It got us to our destination."
Cons: "Seats sucked. Screaming kids. Wouldn’t let us bring our carry-on for the last leg: Lisbon to Barcelona even though there was room."

Cons: "Ok, it's TAP, it's a bargain, but the "breakfast" was a pitiful piece of meat on a stale piece of bread"

Pros: "Food was ok"
Cons: "Worst accommodations for baggage on a international flight in my opinion.Pay for a bag is the best advice in my opinion this airline barley lets you bring anything with. Disgusting plane it was so dirty I took a shower after this flight and the amount of dust in the air was visible terrible"

Pros: "Not much"
Cons: "The offered an upgrade to bid on. I did and was rewarded one for the 4 of us. It turned out that the seats were exactly like every other seat on the plane in size. They did provide free drinks and a well used towel. When you ask to be paid for an upgrade you should be clear what that really is."

Pros: "The crew was great."
Cons: "My baggage did not get delivered to the final destination, that could have been handled better."

Cons: "Boarding was a disaster that took an extra 30 min"

Cons: "The entertainment system did not work and could not be switched off. This issue could only be solved by the crew placing blankets over the screens. This happened both in my seat and my wife’s seat. I don’t think this is acceptable for very expensive business class tickets."

Pros: "Everything was on time"
Cons: "Lots of hidden fees, horrible customer service, no flight entertainment available, seats were uncomfortable. Definitely would not recommend"

Cons: "Hand luggage weighing queue delayed flight, Gatwick flights delays, missing luggage at Lisbon,"

Pros: "On time flight, good service"
Cons: "Long wait for deposit luggage . Food could be much better."

Pros: "The crew were excellent during the flight."
Cons: "We missed our connection flight because our first flight was delayed. Despite getting to the desk when there were still people queuing he refused to let us board. We are now delayed for 30 hours with no money or clothes. TAP staff were horrible- no sympathy or even an apology. Just awful."

Cons: "We called the day before to ask about baggage and was told was included in price of ticket. Only to get to airport and be told was not included and cost 95 euro per bag. absolutely unacceptable and will warn all future associates that travel to Portugal"

Pros: "Excellent landing, adequate number of attendents, food served, wide aisles"
Cons: "I would not do Nee as well ll for the twwwo plus hour flight. If the center seat was occupied as there simply was no space for my knees."

Pros: "nothing."
Cons: "The flight was cancelled few hours before departure. I called the customer service and they a flight to Tel Aviv a day after with 3 stops. It was imposible to accept, so I've cancelled and bouhgt another ticket from other airline and ask for refund. Three months later I still waiting for the money. Not recommend at all TAP."

Pros: "You can charge your devices (only in one plains from London to Portugal)"
Cons: "Cabin crew were far from welcoming when dealing with the African passengers (including me though I'm Spanish) the food was a disgrace On a 5 hour flight to Accra there was no entrainment, the chairs were incredibly uncomfortable and you could not even charge your devices... The food arrive way too early. I believe the airline has put less of an effort on these planes due to the nature of the passengers... I have been traveling for 20 years and I never felt so disappointed by an airline... I will not use this airline ever again"

Cons: "Two TAP flights today. Both flights delayed more than an hour."

Pros: "Flight was only 15 minutes late"
Cons: "Food and drink (esp. non-alcoholic) is terrible. Not offering a vegetarian option - even on short haul - is ridiculous in the 21st century."

Pros: "Free food and drinks. Pillow and blanket and ear buds all ready on each seat! More spacious seating."
Cons: "No indication booking was discounted flight on kayak website! Charges for baggage very , very high!. Very bad border crossing as we waited in line for a simple passport stamp for 3 hours!!!!!!"

Cons: "Flight got canceled and delayed, staffs very mean and unprofessional"

Cons: "flight was delayed. ended up missing our flight from newark home."

Pros: "The extra room and comfort the business class provides"
Cons: "The business class cabins are not up-to-date and state of the art. The seats are not comfortable. On my outbound flight, the seat did not fully lay flat. The electrical outlet was old and worn out and ended up not charging my devices because it was too loose. They need to install USB outlets like everybody else. Needs more luxury like others in business class"

Pros: "Cabinstaff were friendly and professional"

Pros: "Very gentle staff. Good food and service. And I will visit Lisbon next time."
Cons: "Too early in the morning. A better connection in Lis wil lhelp"

Pros: "Efficiency and friendliness of staff with a visible commitment towards passengers on-board (customers). One of the best experience, even though the flight was too short, and even then the airlines served snacks and refreshments... Simply Amazing... A 5-STAR service to its customers... Wow"
Cons: "NONE"

Pros: "Nothing"
Cons: "Never made this flight"

Pros: "The crew were kind and considerate."
Cons: "This was the worst flight I've ever experienced. There was an incessant, loud high-pitched buzzing noise for the entire duration of the flight (we were seated in the very back row so it was particularly loud for us, but others further up said it was bad for them too). Also, we had straight turbulence for over two hours. I've never gotten sick on a plane before, and my husband never gets motion sickness, but we both threw up (and I think several others did, too). I don't blame the crew for any of this, as I know most, if not all, of it was out of their control. However, I would be very nervous to flight TAP again due to this experience."

Pros: "We were late because of delay of the first part of our fly : Zurich - Lisbon, but the fly Lisbon- NewYork waited for us."
Cons: "Our TV didn't work. There is not possibility to charge phone on the fly."

Pros: "Well done...when other airlines offer nothing!"
Cons: "Slight delay in boarding... but arrived on time"

Pros: "I asked if it were possible to change my seat at the gate and was promptly given a window seat. They were very pleasant and professional. Food was very good and movie choices excellent. Good customer service."

Cons: "They cancelled the flight, losted the baggage and couldn't help to resolve the problem. They also lied about the flight they wanted to replace to solve the problem which even didn't exist in their company. So, I will never ever take the flight from this compound again."

Pros: "Ease of boarding"
Cons: "Wait at baggage claim was too long"

Pros: "Complimentary beverages and snacks. Understandable English from the crew about the flight information"

Pros: "Very comfortable flight."

Pros: "La atención del personal es bueno."
Cons: "Los asientos no se pueden reclinar, muy duros."

Pros: "Low cost"
Cons: "Kept switching gates"

Pros: "Aircraft seem well maintained and crews are very nice."
Cons: "Boarding was a mess this time. The lady directing the boarding did not make clear where each group should stand. So The lady had to send most of us back which upset many. TAP should copy Southwest Airlines except self checkin kiosk are horrid no matter which airline uses it."

Cons: "The flight was 45 min late and nobody seemed to bother about it"

Pros: "Crew did a good job of keeping their cool when my flight was canceled and merged with another. After 4 hours of delay because the Pope was traveling to the same place we were and having to hand out all new boarding passes to confused and anxious passengers, the crew were always friendly and helpful."
