Cons: "More comfortable seats"
Pros: "Crew great. Seats were tough."
Cons: "Nothing they could have done but screaming baby for hours was.most unpleasant"
Cons: "Flew in a leased 767, 5+ hour flight. Seats had not been adjusted for US adults - very tight squeeze, both side to side and front to back, extremely uncomfortable. No in-flight entertainment (screens blank the whole trip), and minimal service - not even coffee. Terrible!!"
Cons: "food and I could not check in at the Kiosk. It said I didn't have a flight and I had to wait nervously for 3 hours for an agent to come to the desk. Then I was able to check in easily."
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: "It wasn’t full so we got a row to ourselves people were nice"
Cons: "TXL Airport is super slow with luggage."
Cons: "All airline seats are uncomfortable. It’s the nature of the beast."
Cons: "Seats too close together and uncomfortable, but all economy class seats are the same so far in every airline I have flown."
Cons: "The crew barely came by, the seats were TINY and you have to pay for everything. It was really a bad experience"
Pros: "Crew was very friendly! Flight was very comfortable"
Pros: "Connection gate in Rekyaveck wa. Sry convenient"
Cons: "Seat comfort for a new plane was terrible"
Cons: "The seats are narrow whereby you are overlapping shoulders with the next person. Good leg room for short people. Food/beverage service is limited for a transatlantic flight. Outside of coffee, tea, and water, all beverages are at a cost and there is no snack (i.e., pretzels, nuts)."
Pros: "Great service, but late departure, missed flight in Reykjavik, 8 hours late arrival in Zurich"
Cons: "Waiting for us in Reykjavik to get to Zurich less than the 8 hours late...."
Cons: "They downsized the plane and bumped me and my travel companion. Worse experience of my life."
Pros: "Seats were comfortable and both flights were on time.....smooth rides!!"
Cons: "Very limited food choice."
Pros: "Food was great"
Cons: "Entertainment selection was weird and horrible"
Pros: "The flight attendants were efficient and fast at bringing drinks and food! Overall the menu to order from is pretty good with several nice options. Entertainment system is great."
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: "The plane was late leaving Boston and again leaving Iceland. The seats were very uncomfortable on the first leg of the trip, and marginally better in the second leg."
Pros: "The flight attendants were kind and this was another smooth flight!"
Cons: "We had several opportunities for water and a beverage, but there were no snacks."
Cons: "Seats in business class are uncomfortable. Passenger loading was abyssmal: no advantage -rather a disadvantage - to "boarding" first, the trurh is that we had to wait standing for a bus."
Cons: "I didn't like being charged 95 dollars for my checked luggage with no prior knowledge that that was going to be the case. The website said one free checked piece, but apparently that didn't apply."
Pros: "Getting off the flights! What a terrible experience. We will never fly or recommend this airline again"
Cons: "We will not fly Icelandic Air again. The baggage fees were incredible - $95 per bag to go from Boston and $110 per bag to fly home. That is over $400 in bag fees. This with practically no service, no snacks - we did get water and soft drinks and a ground crew in Iceland that does not communicate about boarding. There was no system to get people on the plane and no communication You expect a baggage fee but it should be well communicated. We looked up the fee online and saw an economy bag listed. What they do not list is that there are different economy baggage fees. The lower price you pay the higher the fee. Again I don't mind a fee - I just should be able to find that fee before I commit. Very deceptive advertising. I could have booked a flight with an airline for the same price and gotten better service, a few snack and airline miles."
Pros: "Everything but having to pay $69 for a checked bag was fine."
Cons: "Had to pay $69 to check one bag even though economy class is entitled to one free bag. We specifically brought a checked bag expecting it was free. Otherwise we would have only done carry on."
Pros: "Love it. Customer service was awesome. Seat quite comfortable. I hade problems with the first entertainment tablet they gave me, but the second worked well. The only reason I mention this is because I don’t think I was the only one who had a problem. I have every intention to fly with Icelandic air again!"
Cons: "Gate area was somewhat chaotic during the boarding process."
Pros: "The seats were comfortable and spacious enough. Also, the entertainment system was really responsive, which is a little thing, but makes it feel nicer and modern. It also had good selection."
Cons: "Being a rescheduled flight after a big storm, security seemed overwhelmed with the number of people. We arrive about two hours before scheduled departure and they were making last call by the time we got there. Not sure what can be done about this, but it was annoying. Maybe the airline could have requested that security open earlier."
Pros: "They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick."
Cons: "Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones."
Pros: "No food or snacks are given on flights even if they are overnight. Everything must be bought other than water and coffee/ tea. Other than that the crew and flight were nice."
Pros: "They were very good about keeping the lights down as much as possible on this red eye flight. Announcements were also kept to a minimum. The re were comfy blankets, pillows, and water waiting for us on every seat."
Cons: "The seats are not that comfortable - seems they skimped on padding, plus my seat wouldn’t stay reclined and my husbands wouldn’t recline at all. The space under the seats in front of us was very restricted: there is only space for a bag or for feet, not both."
Cons: "not being on the plane!"
Pros: "When purchasing of ticket it hide that there is not a complimentary first bag check. To find out at the airport check-in that have to pay additional $190 ($95x2) to already paid price, I feel extremely cheated. According to Iceland Air, its the 3rd party/ Kayak's fault for hiding. I told them they are the one who are using 3rd party to sell tickets so the responsibility goes to both sides."

Pros: "Everything was awesome"
Pros: "I really liked the fun facts about Iceland on seat heads, and the seats were quite comfy as well. Everyone was really friendly. As far as being trapped in a tiny space too high up in the air can be, it was quite enjoyable."
Pros: "Service was good and they took good care of me and my family."
Cons: "Could not hear what the Captain said on the intercom."
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: "Service on the plane was excellent."
Cons: "Long wait to get off of the plane in Reykjavik."
Pros: "On time, polite and helpful assistance at airport with seat assignmnent issue ( all seats on a four leg ticket had been unassigned after assignment three months prior), generous leg room, very good tea on flight. Slept in Reykjavik airport on long layover due to dreadful weather. More comfortable than most airports."
Cons: "All was fine."
Pros: "The price was right. Lots of entertainment options. Amenity kit was nice. Staff/crew very pleasant."
Cons: "Seats were not as comfortable as business class seats on other airlines I have flown."
Pros: "They brilliantly board passengers with window seats first! The seats are roomy and the lighting above the storage bins is a nice touch."
Pros: "Planes were clean and very comfortable. Entertainment was great. Crew was professional and well informed."
Cons: "It was extremely disappointing that absolutely no food of any kind was offered on the 5 1/2 hour flight from Boston to Reykjavik. No pretzels, no bag of nuts, no cookies, NOTHING. The only thing handed out on the 5 1/2 hour flight was a bottle of water at the start. There wasn't even a choice of beverages. I would very much have appreciated knowing that beforehand, so that I could pick something up at the airport to tide me over. Needless to say, there was only water offered on the flight from Reykjavik to Hamburg. I cannot overemphasize-- Icelandair should at least clearly inform passengers in advance of their overseas flights that there will be no food service."
Pros: "Flight was cancelled"
Cons: "Was not notified of the cancellation until arriving at baggage check. Instead of putting us on another Iceland air flight, they put us on Virgin Atlantic connection to British Airways. The Virgin flight was 2 hours delayed so we missed the connection and then it was not clear who's responsibility it was to get us to Paris."
Pros: "The seats were comfortable and not as cramped as other airlines. I wasn't prepared for the exchange rate, the cost of food purchased on the plane showed up as dollars on my debit card account."
Pros: "flight crew was very professional"
Cons: "Actual flights were fine. Connection in KEF was confusing due to poor signage (Gate C23), no staff, and no chairs at gate. "Am I really in the right place?""
Cons: "Our seats were said to be together but were across the aisle from each other, the boarding process was quite delayed and rather chaotic, boarding passes could not be printed (the attendants were very kind and tried to help). My bags were also lost between this flight and the next."
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: "The water and longer seat belts."
Cons: "Poor communication at the gate when boarding leaving many people looking around lost and confused. No real boarding process - a real scrum once on board. Can't even provide a small bag of nuts or chips, very limited selection of beverages which are complimentary and the foods offered for sale did not have much option for people with dietary restrictions (and I didn't see a place to special order). Besides hard seats and outdated movies and screechy classical music, what can I say about the entertainment. Not all seats and entertainment equipment in working order."
Pros: "On Time, efficient."
Cons: "The stewardesses disappeared and were hard to contact."
Pros: "Comfortable, good food and good crew"
Pros: "The crews were awesome and very friendly professional"
Cons: "I booked a business class, round trip ticket, only to find out that one of the legs was not."
Pros: "The selection of movies was great. Boarding happened super fast and plane departed early."
Cons: "Plane was incredibly cold! Touch screen didn’t work well. Breakfast was lame. Flight attendants were super loud during breakfast service even though the lights were still dimmed."
Pros: "It was short and with friendly staff."
Cons: "No complimentary refreshments."
Cons: "Best flight I have ever been on"
Pros: "The crew was efficient and well trained"
Cons: "The food needed salt and the bread was a little dry."
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."
Cons: "The seats could have been more comfortable and . The plane was over booked"
Pros: "The crew was as amazing as they were 9 years ago when I flew Aer Lingus. The plane was very clean and comfortable. The entertainment that we could choose from very good. Something for everyone was provided."
Cons: "One thing that I would like to see improved is for the announcements to be spoken slower than they were. The announcements were so quick that I could not understand what was being said. This should be an easy fix so I have no worries ."
Cons: "Overall pleasant More pleasant than with some other carriers recently"
Pros: "Both ground crew and flight crew were courteous and friendly."
Cons: "The meal was between edible and mediocre. It would have been nice if the hot beverages were served with the mini breakfast before landing."
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: "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: "Staff were nice"
Cons: "The seats were exceptionally narrow. Seats were firm and uncomfortable, my entire body was aching and it was impossible to sleep bc the cabin lights were on the entire flight . I’ve flown to Europe via British airways before and I can’t even compare the two. THe thought of having to fly back in the same aircraft is giving me cold sweats and i wish I didn’t have to"
Pros: "Pretty good flight for a good price."
Cons: "It would be so nice to have tea and/or coffee served before landing. oming in at 5am or 1am North America time is difficult and if you have to travel more that day a cup of coffee or tea sure would help. Serving tea and coffee at ten pm after serving dinner isnt good if you want to sleep..just keep it warm and serve it before we land."
Pros: "That it only lasted 50 mins"
Cons: "Packed with low class beer drinking plebes."
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: "Was exceptionally impressed that the cabin crew made a cabin-wide announcement concerning a passenger with a peanut allergy. Other airlines could learn a lot in this department. Keep up the good work!"
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: "the entertainment system is not good as other airlines, also the served drink is not good."
Pros: "Was part of my international flight"
Cons: "Was part of my international flight"
Pros: "Nothing but the price, flight was Aer Lingus to PRA and was less than expected"
Pros: "Ahead is schedule"
Cons: "Even had to pay for coffee"
Pros: "Fast. Not too much time wasted between connection. Dublin = small airport, it's really comfortable..."
Cons: "Not enough room for my legs Too close to the "babies rows" = difficult to sleep. It's a pity to pay now to change a seat in the same category"
Pros: "Friendly staff."
Pros: "We had an excellent experience flying with Aer Lingus! We had a little trouble in the beginning due to my husbands CPAP machine. We did not realize you need a doctor’s note in order to fly! The first girl, Ajla, was sweet and just doing her job as she explained to us that we needed the note. My husband and I were upset, but she remained calm and kept a smile on her face. She got her supervisor, Ismail, to help us with our situation. We were able to resolve our problem with his help and check into our flight. Sean P helped us check into our flight and got us all situated. Ismail was amazing and upgraded our seats AND escorted us through security to make sure we would get to our flight with extra time to relax before we boarded! After our rocky start at check in Ismail made everything all better!! I highly recommend this Aer Lingus team at Logan International Airport!"
Pros: "Flight attendants were nice looking, very friendly, smelled nice they could not have been warmer people!!"
Pros: "everything was good as usual"
Cons: "check-in desk couldn't check me through to my connecting flight with Virgin Atlantic so I had 15mins once landed in Heathrow to get through passport security and checkin at Virgin Atlantic desk.... I'm young and fit so was able for the dash but elderly or familys would not have made the connecting flight in that time"
Cons: "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 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: "Having two seats together but separate from the others. The departure time and connection to Edinburgh were also convenient."
Cons: "As with most other airlines, I don't like not having a direct flight from Boston to Edinburgh."
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."
Pros: "The crew was helpful and the plane was clean."
Cons: "The rows were terribly tight (no one in my group is over 5'1" and neither of us could cross our legs). The cabin was too bright and the announcements were too frequent to be able to rest."
Pros: "Service was great, everyone was really helpful"
Pros: "Comfortable Clean"
Cons: "Food/drinks a little expensive"
Pros: "Crew were professional and attentive Plane was clean and mechanically sound Take off and landing were on time or earlier"
Cons: "Because we bought seats from a third party vendor and not directly through Aer Lingus, we had terrible seats (right across from the bathroom) on both long flights. We could not check in on line until 2 hours before the flight and the seats available to us were single seats with no options to change. The AL staff at the airport told us that we should have booked through them directly but as you know the flight prices would then have been several hundred dollars additional for each. Seats were SO CLOSE, way too close for a 6+ hour flight Crew allowed passengers to drink alcohol until they were totally inebriated, which was unpleasant for many of us"
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: "Great flight, smooth, nice crew, newer movies to watch, I couldn't ask for anything more"
Cons: "Nada"
Pros: "Good"
Cons: "Good"
Pros: "Sleeping and being left alone"
Cons: "Food, Service by cabin crew because they never smiled"
Pros: "It was on time and everything went well"
Cons: "They could have offered more water"
Pros: "Super friendly"
Cons: "Maybe a hot meal?"
Pros: "Crew was awesome, seat spacing comfort not so much."
Cons: "Need to have seat upright to use trays to eat on flight"
Cons: "Boarding process was disorganized and no announcement was made about paper boarding passes and not accepting electronic ones. The seats were very cramped"
Cons: "They took an extremely long time clearing away the dirty dinner trays, which meant that the tray table had to be down. This made it near impossible to get up to use the restroom or to stretch."
Pros: "flight was more than 4 hours late!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Cons: "flight was more than 4 hours late!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"
Cons: "Passport control in Lisbon was awful and many people missed their flight in spite of them being made aware of the issue."
Pros: "Encouraged to take the pillows home they were nice"
Cons: "Headphone jacks that work would have been nice. 6.5hr flight without sound! The crew disappeared and would only give half cups of water when asked for. ALCOHOL not just wine and warm beer."
Pros: "loved the pillow and the blanket and the movie options"
Cons: "Terrible terrible service in helping with a tight connecting flight, terrible"
Cons: "bumping and no coffee"
Cons: "Very warm in cabin, no means of controlling air flow. Seat space very cramped. Very tall person next to me in my space"
Pros: "Nothing"
Cons: "Everything"
Cons: "I am an Asian woman. After seeing the person who is a Caucasian man set next to me used the toile right in front of our seat twice during the flight, I went to use it. Just as I was entering the toilet a flight attendant yelled at me saying: "you can’t use this toilet. It’s for privileged people. You have to go to the end of the aircraft and use that one!" Then 10 minuets later another caucasian man seated behind me went to use the toilet right in front me without any problem."
Pros: "Great flight, friendly and helpful crew."
Cons: "Didn’t connect to entertainment didnt"
Cons: "Not getting new business configuration"
Pros: "overall good service; seats are full recline leaning type, which isn't the most comfortable solution, but ok."
Cons: "TAP connecting flight was three hours late"
Cons: "We had to pay $200 each way to check in a luggage and just pick regular seats. That was not clear when we bought tickets. Additionally, they don't announce the gate until 30min before boarding. If you're going through passport control that can be a 45min process. On top of that even though I paid $100 to reserve seats, when we arrived at the gate the seats we reserved weren't reserved. Why did I just pay $100?! Luckily I had receipts. Our connecting flight was delayed 4 hours, making our layover 7 hours! For an hour flight. This is the worst airline."
Cons: "I don't think I have ever rated any service negatively, but here's my first. TAP completely ruined my birthday trip that I have saved up for a long time for. DO NOT TRAVEL WITH THEM! I had a valid Schengen tourist visa issued by the Consulate of Portugal. At the time of visa issuance, the printer of the Consulate was not functioning, so part of the visa information was hand-written, but it was properly signed and stamped. The Consulate told me it's valid and said they have been doing so for ten years. The Consulate also said that they, not the airlines, have the sole authority to determine the validity of the visa. When I went to the airport to check in with TAP, TAP staff denied me boarding because they did not believe my visa was valid. I only learned later that this action was inconsistent with TAP's own internal policies. The staff at the kiosk told me that I could either ask for a refund or rebooking of the ticket. But when I called TAP the next day, I was told I could not get a refund even though they should not have denied me boarding. I called TAP many times and got a different answer each time. They simply refuse to compensate me for their own mistake. It's the most horrible travel experience I've ever had!"
Pros: "Price"
Cons: "Business flat seats quite restrictive"
Pros: "The staff were really friendly and the flight was as comfortable for me as a transatlantic journey in stage class can be. The food was surprisingly tasty and that Portuguese wine was offered for free made me and the passengers around me feel welcomed and well taken care of."
Cons: "My flight arrived late, apparently, as myself and people on two other connecting tap flights all deplaned after our respective boarding calls had begun. There was no announcement for people with tight connections or about what to do if we couldn't make them. That tap didn't plan out sufficient connection times for the conditions of the airport, and that it was security, not to itself, that did anything to try to expedite is through passport control, etc was disappointing and resulted in several extra hours stuck in the airport for me and for those on one of those other missed flights having to wait overnight for another seat"
Cons: "Our flight leaving Boston was delayed by 2 hours due to a mechanical issue. So, we missed our connection in Lisbon to Venice (our final destination). We were rerouted from Lisbon to Rome and then to Venice, turning our 2 leg journey into a 3 leg flight. We were offered just 16 euros worth of food vouchers for our trouble. We asked for lounge access because missing our connection meant we had to cool our heels in the Lisbon airport for 3 hours until our flight to Rome took off. We were told we'd have to pay for the lounge! Then, our flight to Rome was delayed. We stood at the gate for 40 minutes past boarding time. No staff even announced that the plane was delayed or how long we should expect to wait. When we finally got to Rome, we had 10 minutes to make our connection to Venice. We lost an entire day in Venice."

Pros: "There was great entertainment on the first flight"

Pros: "very rude empoyees at check in"
Pros: "Overall flight was smooth and crew seemed nice."
Cons: "Flight was delayed leaving Boston due to an ac problem. In the end they got it squared away but we sat on the plane for an hour at the gate with absolutely no air flow and it was pretty uncomfortable. Feel as though they should've come around and gave waters, etc to passengers. Also could have improved the selection of in flight entertainment, not many offerings"
Pros: "Comfortable seat"
Cons: "No lounge airside at Lisbon airport, no shops open that early in the morning"
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."
Pros: "Everything was good"

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: "All was good."
Pros: "The food was good and the seats were very comfortable. The selection of moves was alright. The crew was very gracious despite all the problems with boarding."
Cons: "The boarding process could not have been worse. Both legs were delayed because of bag issues. One leg a significant portion of us had to get off the flight because there was not room for all the luggage. They made me a check my carry on bag because it was over small mediocre weight requirement even though lots of people had heavier bags. Then they LOST that bad for 2 days and it was a nightmare getting it back in another country. The second leg, a person whose bag was on board was unaccounted for, so we were delayed again."
Pros: "Flight was very good and comfortable."
Cons: "My luggage did not arrive to the final destination."
Pros: "the flight itself was great"
Cons: "the airport in Lisbon is really disorganized with few people to check all the passports, so it took a long time to get to the connecting flight."

Left at 6 am next morning . Got to Sao Miguel and missed my flight that was to leave the day before. Made me wait on stand by before putting me up in a grand hotel with no luggage. It was Still in Boston. I had to buy things to wear and use. So late no dinner at hotel . Terrible"

Cons: "No entertainment. Or difficult to access."
Pros: "It was beautiful"
Cons: "My brain new luggage was very badly damaged"

Pros: "Couldn’t drink it since I am pregnant, but free wine with dinner."

Pros: "nothing"
Cons: "5 hrs delay and missed all connecting flights. Airline initially rescheduled flight 2 days later. Called Kayak and got no support. Kayak agent told us to keep pushing the airline. After 2 hrs of "working" with the airline, we were able to fly into Madrid the following day. Had to spend extra money for hotel room and car rental in Madrid because our final destination was Sevilla. Will never work with Azores or Kayak again. BTW, did we mention that while "working" with Azores to reschedule flight, we were booked to fly into an island off of Africa. Luckily, we followed up online with the changed itinerary."
Pros: "IT WAS ON TIME"
Cons: "PACKED IN LIKE SARDINES"
Cons: "Seats are too small"
Cons: "I think the through flight through Portugal should have been more transparent. Myself and many others did not know about this flight until arriving at the airport. Regarding entertainment, there was no movie or anything like this for the long flight."
Pros: "Service and the upgrade"
Cons: "Nothing"
Pros: "Did not enjoy anything about this airline or flight. Everything is so backwards"
Cons: "Flights on Azores Airlines/SATA are always delayed. It is a shame that it is the only airline that flies to Terceira Island. They delay flights due to "operational issues" because they cannot get their stuff together. The crew was also unfriendly and while we were already 4 hours delayed one of the crew members (leader) had the audacity to tell her team "why are you guys in a hurrry for?" HELLO! We are already lady. Work harder and faster so we can make up some time. The food was disgusting and they barely give you anything to drink. Also, the planes are very old. Seats uncomfortable, no leg room, no TVs and stink."
Pros: "Everything was smooth and comfortable."
Cons: "There is no in- flight entertainment."
Pros: "Everything was easy!"
Cons: "Everything was fine thanks."
Pros: "Crew were lovely. Economy seats were pretty comfortable, with legroom. They allow one free checked item. Free food!"
Cons: "I ordered a vegan meal and got pasta with cheese. We were half an hour late taking off."
Cons: "Airline was 2 hours late and missed our connection which made us miss our first port for our cruise we then had to make other arrangements while the airline did nothing to help. I would NEVER FLY with them again."
Pros: "Crew was nice enough"
Cons: "Flight was delayed over 3 hours causing me to miss my connecting flight upon arrival in Lisbon. No in flight entertainment, only one meal served, no spot to plug in electronics, and the bathroom door was broken and didn't lock. I would suggest paying a little more for a better and more reliable airline."
Pros: "Crew members were O.K."
Cons: "- There are no more direct flights into Terceira (coming from the U.S.A.) which is ridiculous!!! - Both flights were delayed. The one from Boston to São Miguel was delayed 4 hours. The flight from São Miguel to Terceira was delayed in 30 minutes. - As if the delay wasn't enough, we had to return to gate as the plane prepared for takeoff because of technical problems. SATA (Azorean Airlines) international planes are too old..."
Cons: "Way too warm, uncomfortable seats, no entertainment"
Pros: "Not much"
Cons: "Never had such an uncomfortable flight! The temperature at my seat was far too hot- I and others were sweating constantly. Also I am 6' 3" but wouldn't recommend anyone over 6' fly this airline, at least not in the normal economy seats- I've never had the experience of being unable to move my legs due to the seat in front."
Cons: "Long delay, no apologies, uncomfortable all around"
Cons: "They sold me a flight jknowing it was delayed by more than 13 hours"
Pros: "The flight was on time!"
Cons: "Seating is ridiculously tight!"
Pros: "Free food and beer"
Cons: "3 hour delay and sizee of seats - SMALL pitch!"
Pros: "I liked the food and champagne :)"
Cons: "Didn't appreciate the fact that my flight was canceled and changed for a day later"
Cons: "They cancelled the flight a couple hours before ltake off, then changed the flight number and took off with all the people they bumped from the day before. What a scam, told us it was "operational issues'""
Cons: "DELAYS, BAD CUSTOMER SERVICE, NO ACCOUNTABILITY."
Cons: "Long delay not on time"

Cons: "The boarding process was disorganized"
Cons: "Flight was cancelled"
Pros: "The flight crew was absolutely wonderful and very helpful with our 3-year-old son. He keeps asking to go on plane again because of how attentive they were and made his trip very enjoyable."
Cons: "No entertainment at all. The seats could have more recline as it was an overnight flight and nearly impossible to sleep. The trays for business class are so close that it is awkward and uncomfortable to use."
Pros: "serves wine for free."
Cons: "No entertainment, seats are extremely small and uncomfortable."
Pros: "1 booked flight and selected seats months ahead. On date of departure reseated in middle section though previously booked window seats. 2 after arriving in Portugal informed return flight was cancelled due to crew strike. Told we can wait in Portugal or rebook on new airline. You can't make this stuff up."
Pros: "It was a economical flight. The food was pretty good as well."
Cons: "We had changes to pretty much every leg of our flights. One was delayed by 2.5 hours. I understand that flights get delayed but they hardly gave us any information as to what was going on. The flight was pretty smooth but the flight attendants didn't seem interested in our comfort. They weren't rude but they weren't pleasant either. I guess I'm used to a different style of service that I did not receive on Azores."
Pros: "Flight was on time. Staff was courteous."
Cons: "Food was average. No entertainment."
Pros: "Crew was attentive and it was a direct flight"
Cons: "There was very little room in the seats. It was terribly uncomfortable and made worse when the seat in front was declined"

Cons: "packed in like sardines"
