Pros: "This was my first and last time I will ever fly with Swiss airline-it’s been 4 days and I still didn’t receive my baggage and I had all my medicines in them,that’s including my carry on bag too,because it was taking from me @ the gate and I was told I will get it at my final destination,which I didn"

Cons: "Lost our bags"
Pros: "Crew good"
Cons: "Baggage small bag forced to check"
Pros: "the CREW WAS FRIENDLY AND CELEBRATING EASTER WITH THE GUESTS"
Cons: "THE FOOD WAS ADEQUATE, GIVEN THAT WE WERE ON AN AIRPLANE"
Cons: "We were happy with everthing"
Pros: "I do not know how to go about contesting his, but we bought 4 tickets to South Africa on Swiss air and Edelweiss via Zurich. We received a confirmation email for two of the tickets but not for the other two so we assumed the other ones did not go through as we used two different credit cards."
Cons: "We purchased the last two again and when we showed up at the ticket counted they let us know that we bought 6 tickets!!!!!!!! We would like to be reimbursed for the two tickets we did not receive the confirmation emails for. How can we go about it?"
Cons: "First plane from Barcelona to Zurich was turned around mid flight for medical emergency. Missed connection flight and had to wait 24 hours for next flight to LA."
Pros: "We have been flying Swiss for years and they are the most reliable and best organized airline, we have ever experienced."
Cons: "I didn't notice that I had booked some sort of new economy light category where checked baggage is no longer included and to check baggage when booked into this class cost $60 per bag per flight. So overall on the trip I paid $240 extra for luggage alone."
Cons: "Food selection was a bit short"
Pros: "On time arrival"
Cons: "Boston -Zurich, the most uncomfortable seat possible. I am 5’2 and I barely fit.... Seats are way more comfortable on European flights."
Cons: "They lost our bags for the second time in 4 days. Both originating flights were late starting and made for impossible connections! Is Swiss ever on time? Frustrating for sure!"
Pros: "I was very pleased at the flight crew, the food and entertainment. We had a really fast connection in Zurich and our luggage made the connection, which was a big relief."
Pros: "Entertainment"
Cons: "I would have liked a better selection of movies and TV series and games"
Pros: "787 is an excellent plane and I could sleep a little"
Cons: "I was boarding at gate C4. Doesn't anyone get it ! Using the word "bomb" in airports is a big no-no however C4 is OK? Even a little old lady knows what C4 stands for."
Pros: "Everyone was so nice!"
Cons: "There was nothing I didn’t like."
Pros: "Since the flight from Palermo was 1hr. late. Swiss air took us privately to check our passports and directly into the plane. That was Excellent Or we would have missed our flight. We made it into the plane, too bad our luggage din`t."
Cons: "Not enough room between seats for international flight."
Pros: "Staff and flight was really great. Everything went smoothly and on schedule. The plane was clean."
Cons: "The seating was almost unbearable. So small and cramped. Arm rest didn’t go all the way up so very hard to cuddle with my seat mate (my daughter). I couldn’t even put my arms by my side without pushing my seat neighbors off. Seat in front of me was in my lap. Hard to get out of seat to use restroom. Way to tight. Long flight from Boston to Zurich was so hard to bear. I understand making money...but this is ridiculous!!"
Cons: "They rebooked me on a later flight this same day. This flight to Geneva (change of airports) was late and the flight to Vienna took off with no passengers from our flight, after we were told it would wait. ' I paid for premium seats and did not get rebooked for the same. I am sitting in the Geneva airport for 7 and 1/2 hours, losing my meetings in Vienna. I never expected such poor service from Swissair."
Pros: "Good service - including snacks and drinks. Smooth flight."
Cons: "Upon boarding, the agents in the airport gave us a hard time over a bag that definitely met carry-on requirements. Almost made us check it, and then changed their mind last minute. Very unnecessary/dramatic situation, especially since we flew with that bag via carry-on multiple times (and on even smaller planes)."
Pros: "Flight crew, food, and seatback entertainment system (with USB charging port) were all great."
Cons: "The seats were uncomfortable and way to close. When the person in front of me leaned their seat back, I was forced to do the same. It was nearly impossible to eat. If you had a hint of claustrophobia, you would never make this entire trip without going nuts. I noticed that many of the middle seats were unoccupied, while my family and I were crammed into four seats side-by-side. If we had empty seats between us the flight would have been bearable."
Pros: "Good space above seats"
Cons: "Seats way too tight. But the worst thing was the two passageners in the row we shared. They were laying on each other and it was inappropriate for the entire flight. He was rubbing her breast and I said something. He seemed to stop. Lots of rubbing and huggin and the man had his legs stretched out man spread style"
Pros: "Crew was courteous."
Cons: "Nothing"
Pros: "I really liked the "About my flight" application on the viewing screens because it always gave me an idea of what we were flying over and how much longer we woulld be in the air. The food was excellent and I was pleasantly surprised that I could have wine with dinner or any time the attendants offered beveragess. The attendants were always professional and helpful. They all were fluent in English as well as several other languages. It was a nice touch when the attendant wore white gloves when he or she was collecting passengers' trash after meals and/or beverage service. I loved the cheese that was served at dinner."
Cons: "My seat was a little confined when I put my carry-on bag in front of me on the flight to Zurich, but it was roomier when I stowed my carry-on in the overhead compartment on the returtn flight."
Pros: "Prompt and business like"
Cons: "As a business passenger I was told to go to the Avianca lounge this lounge is not Swiss standards the man sitting next to me was in a t shirt and swim shorts I started flying all over since 1952 most in the back so sorry to see such relaxed protocols"
Cons: "This plane was better."
Pros: "Swiss' Zurich Airport Business lounge is the most comfortable I've experienced. The flight attendants were professional, courteous and very helpful. A very enjoyable flight experience in business class."
Pros: "We actually did not fly with Swiss Airlines to Thessaloniki. Our flight was re-booked on another flight the following day with Aegean."
Pros: "The crew really went out of their way to accomodate and made sure I found my seat, was entertained and was comfortable throughout my flight."
Cons: "It was delayed a little."
Pros: "Aircraft clean, staff friendly and efficient"
Cons: "Lighting in aircraft is too bright Food offers by swiss in economy is terrible. My company di a not support business class travel"
Pros: "Friendly staff"
Cons: "This aircraft should be retired long time ago"
Cons: "see above"
Pros: "Business Class price was 50% lower by buying the ticket on El Al site rather than buying direct from Swiss Airlines."
Cons: "There was a supposed difficulty with my entry in Europe when I tried to Check into Chicago. I thought that I had to cancel my flight. Swiss air representatives had to do much consultation, which took nearly an hour, while I was standing there the whole time. At the end, I was thanked for my patience and told all should be well and not even given a small upgrade for the distress this caused me. Traveling is disagreeable in general now, and personally, even moreso after this episode."
Pros: "Nothing! It was the first day of our honeymoon, and it was ruined by Swiss."
Cons: "This (attempted) flight was like living a nightmare. The aircraft had a problem with the A/C, so we sat in the extremely hot aircraft on the tarmac for 2 hours while they tried to fix the problem. Then, when we were finally told that the aircraft could not fly, the Swiss staff said that we were "not allowed" to leave the aircraft. After stressed passengers confronted the crew demanding to be let off the aircraft, we went back into the terminal to wait for hours in line as just two Swiss staff filled out hotel vouchers by hand for over 200 passengers. Adding insult to injury, we were then told to wait for a hotel shuttle at the curb, despite the fact that the shuttle had stopped running hours earlier at midnight. I didn't fly to Switzerland until the next day, losing hundreds of dollars on a missed hotel stay in Zurich, and travel plans. And it was an awful start to my honeymoon. The way the Swiss staff treated us was unconscionable and insulting. They have not responded to my several written complaints, so maybe Kayak can help!!!"
Cons: "We have bought our seats, but in the airport it was found that our seats were assigned to somebody else and nothing could be done to give them back to us"
Cons: "I had a good seat, the plane was comfortable and the crew was nice"
Pros: "Friendly cabin crew"
Cons: "Again, boarding was chaos. No special boarding for star alliance gold member."
Cons: "Delayed boarding due to overheated plane, when we did board it was still warm and we had to sit longer due to other mechanical issues. Wish they would have waited for all issues to be resolved before boarding."
Cons: "I wasn't on it so I wouldn't know."
Pros: "Swiss planes were clean and everything worked. Flight attendants very friendly. Food was superb. Plus, the connection in Zurich, as always, was seamless and painless. Will definitely give Swiss my preference when looking at trans Atlantic flights."
Cons: "Nothing."
Pros: "The entertainment system"
Cons: "Direct answer is "nothing"; however, it should be noted that this not a Swiss Air flight. It was a code share on a United Airlines flight."
Pros: "Great tasting food and lots of movies to choose from"
Cons: "Wish they would board the plane from the back to the front. Maybe that would eliminate the back up in the aisle during boarding times."
Pros: "Direct flight"
Cons: "3 hour delay Noisy cabin due to loud engines One could hardly heard the movie audio from the Headphones during movie viewing even after they were replaced"
Pros: "Crew was friendly and made a bad situation as comfortable as possible."
Cons: "The flight was delayed for almost 3 hours for a issue with the pilot's chair. The movies reset in the middle of the showing."
Pros: "Courteous crew, good food."
Cons: "The beer selection could use some work."
Pros: "Overall service was excellent and staff was courteous and helpful."
Cons: "None"
Pros: "First leg was on United (codeshare) 767. The seat pitch on that version was good, even for a tsix-footer. The flight was almost empty, so there was plenty of room to stretch across seats and sleep. In order to avoid dairy, I order kosher meals - and the quality was OK. The cabin crew was nice to start with, and very relaxed and friendly as the flight progressed because of the low-stress service for so few passengers."
Cons: "No complaints."

There was no special meal on board even though I spent hours on hold to request one!

Pros: "Great staff , amazing dinner, and the entertainment screen size was best"
Cons: "Seats could be a little bigger"
Pros: "Crew was very attentive and professional."
Cons: ". The economy seats on the Lufthansa A350 were extremely uncomfortable and seemed excessively narrow as well has having cramped legroom. I could not get comfortable let alone sleep, and my backside felt like I had been sitting on a park bench rather than a long haul coach airline seat."
Pros: "Nice crew"
Cons: "Better food, some entertainment, better bathrooms"
Pros: "Crew was excellent."
Cons: "n/a"
Pros: "My flight was delayed four hours, so I missed my connection to Sofia and had to re-book for two connecting flights instead of one, which makes for a long, tiring trip."
Cons: "I understand the delay due to weather conditions, but I wish I was rebooked for one, not two connecting flights. Now, instead of flying directly to Sofia from Frankfurt, I have to go to Munich first and then to Sofia, which makes my trip 9 hours longer"
Cons: "They told us there were no earbuds so recommended using our own. Our children had left theirs at home so they ran to get a $20 pair nearby. But the the plane DID have the buds; what we did not have were blankets — the crew said none were to be had."
Pros: "I loved the Awesome Check in lady from United airlines, her name is Sandra and she is pure awesomeness. I also loved the air hostesses for the care they have given me from the time I set foot On the plane until I left."
Cons: "The attitude of the Lufthansa gate staff was anything but welcoming. Reaching the gate for the Lufthansa flight was greeted with my name shout from a distance, and my apologise for being late were met with shrugs! Not only that, but my 3 checked bags are still in at IAD, I didn’t receive in CAI!"
Pros: "Efficient boarding, friendly crew, nice range of entertainment options."
Cons: "An economy seat is an economy seat ...."
Pros: "Very amazing"
Cons: "N/a"
Cons: "I did not like the fact that the United flight I came in on was over a MILE of corridors away from the outgoing flight."
Pros: "Nothing"
Cons: "The flight left 19 minutes early, stranding 7 people who were connecting from New Orleans. We ran across the entire airport and made it to the gate before departure time. The employee at Lufthansa Senator lounge was nice enough to tell us that the crew must have felt like leaving early. She was very nonchalant about the whole issue. She also refused to assist us, and told us we needed to exit the airport and reenter through the ticketing counter. I upheld my end of the deal by reaching the gate in time. This situation needs to be rectified."
Pros: "The crew was incredibly kind and welcoming! And it wasn't a packed flight which made it much more comfortable."
Cons: "No entertainment"
Pros: "Diner"
Cons: "Was told that an upgrade to premium economy entitled us to lounge privileges. Were told by attendants that we had to pay an extra $35. each. We had $6.30 subs from potbelly."
Pros: "Everything on the flight was very efficient and organized—the boarding process, the excellent and pleasant service, the food, and the entertainment selections. Thank you for making a long flight enjoyable."
Pros: "Impecable service. Even worth flying through FRA."
Cons: "Nothing. Everything, as always, great. Keep it up."
Cons: "Walked a very long way in Frankfurf airport to transfer to another flight."
Pros: "The boarding was fast and effective"
Cons: "The plane arrived late and I had to rush through Munich airport to make the connection. But the luggage arrived with me."
Pros: "Food was great."
Cons: "Entertainment was frustrating"
Pros: "SERVICE"
Pros: "They were nice"
Cons: "They were good"
Pros: "Service was very good, flight was very smooth"
Pros: "Restful flight"
Pros: "The in flight crew was great"
Cons: "I arrived a bit late to the airport. 5:15pm for a 6:05p for an international flight. I realize It is very late. I was delayed by donald trump protestors blocking the highway (not your fault). Dulles was a ghost town ( abnormally slow). All I had was carry-on. They said they closed the flight. They quoted me at $1800 for a one way ticket directly from Lufthansa. The original round trip was $900. I declined, sat down for 15 min booked another Lufthansa flight online for $800, checked in and was through security by 5:50. Just in time for my original flights last call. I could have made it easily. Boooo Lufthansa booo."
Pros: "Nothing."
Cons: "The flight was delayed, they said due to weather, but would not let me off the plane to make other arrangements. Terrible customer service by partner airline, United. The airline did NOTHING to help me out."
Pros: "All round excellent services. Food is good, but I wish but I wished More chooses or selection."
Cons: "A man sitting behind me probably took off his shoes and it was just terrible to smell his stinky feet..."
Pros: "the two older female stewards spoke slow enough so I could understand. The customer service rep in the lobby was always friendly, knowlegeable and able to help me. For example, I did not know, when boarding, if we had to show our passports, but I asked him and we did not. I did not grasp the five levels of boarding he mentioned. I knew our group was not handicapped and we were economy, but I did not really know if we were group 4 or 5 to board."
Cons: "There was one female steward who made me take my carry on bag from the upper deck and store it below my seat so another lady's much, much larger bag would fit. Her bag was so large, I can't believe it met the standards. On the other hand, this procedure may be the way things work out,for the good of everyone, but it came as a surprise to me. To accomplish the task, she even asked another female to move her carry on from the rack above her to another several rows down. This lady's hair was too big for such a small plane. She talked way too fast in the first monologue. The plane seemed cheap and the sub airline had an air outlet that would not turn off and leaked with water mist. There was an air conditioner that also had a water vapor leak overhead, which my son said was a 'strip' which he could not control. We were seating in the back row. We noticed the plane was operated by Mesa airlines and the plane was assembled in Brazil, giving me a feeling of excessive cost cutting. Also, the pilot had an accent that sort of added to the 'Brazil' thing that he was not a native English speaker. However, he had a good landing at Atlanta near midnight. I did not feel I was on a real 'United' Airlines flight."
Pros: "Our experience flying with Lufthansa was very pleasant. The overall process of making connecting flights through Frankfurt was much easier than we had anticipated. The cabin crew was friendly and courteous. I will be flying Lufthansa again."
Cons: "I would appreciate the ability to check in and get seat assignments at least 2 days before the flight. The day before traveling can be fraught."
Pros: "Smooth flight"
Pros: "My parents had a wonderful experience. Very professional and courteous!"
Pros: "Comfortable, new aircraft. Good on-board service."
Cons: "Lufthansa should allow seat selection in advance. Other competing carriers do, without a fee (including Brussels Air), and it detracts from the experience to have this uncertainty."
Pros: "Food was actually pretty good, and was plentiful. Comfortable seating."
Cons: "I don't think my tv worked."
Pros: "The flight was delayed two hours. I flew them 10 years ago and thought their seervice rivaled the Asian airlines. Now their service and seat comfort is near the cellar dwellars. The premium coach seat I paid extra for was the narrowest coach seat I have ever had the misfortune to sit in. I am a small man. 5'*8" 165lbs. The normal sized man next to me and I had to sit with our elbows pinned to our ribs. Eight hours of hell. I also had a totally irritating woman from syria behind me. She pushed and banged on my seat back the entire 8 hours. She had to have her loud mouth yapping most of the flight. That was the worse experience I have had flying. Also the attendents didnt care about me. I had to ask for tea. Had to ask three times as they were waalking off"
Cons: "The flight was delayed 2 hours. The seat was tiny , cramped and uncomfortable. I travel a lot. This is the first negative review I have written in 55 years of flying."
Pros: "Fast boarding, on time"
Cons: "Too cold in plane, announcements too loud"
Cons: "Boarding three planes to three different destinations from the same gate is very confusing."
Cons: "flight was late, check-in people were mean and angry to everyone, instead of serving the food straight away since the overnight flight was delaed and then quickly turning the lights off, they waited until 3 hours in to serve food, which meant they didnt turn the lights off until well into the night and only gave us a couple hours to sleep. there were no new movies on board except for batman vs. superman. food tasted weird even for airplane standards. pretty bad overall. i've had better experience with virgin, united, or air france."
Cons: "It was too cold on the plane."
Cons: "The flight was canceled"
Pros: "On time!!!!"
Cons: "We were in economy class. It looked like the seats my wife and I were in were smaller than the surrounding seats. The seat I was assigned was also more narrow than the one my wife was assigned. I am tall, and could not move my legs for the trip. Also, the seat controls were on the inside is the seat. I could not move at all without turning on the overhead light or screen."
Pros: "we sat in row 9 which has extended leg room so it was a pleasant surprise."
Cons: "the staff were not very good at reading the different instructions and one of the gentlemen was of Asian decent and it was very difficult to understand his English."
Pros: "Nothing to like since it was cancelled"
Cons: "This was a very long day and when we were told the flight was cancelled and we should rebook there were 350 people being handled by 3 airline personnel and no organization or info was available to all of us in line. It took over an hour to get to talk with someone and then we had to wait for another half hour before we could get our voucher for a room and breakfast after having no dinner! Really bad, but the next day we had an easy flight, just got to our destination late and missed several tours we had booked."
Pros: "Unfortunately expectations on flights are so low that I am hesitant to say much. It got us there in one piece and I guess that is considered nice these days."
Cons: "I don't normally expect much of airplane food but this was a very low end food for an overseas 8 hour flight."
Pros: "The Munich airport is awesome. My wait from my connection went smoothly and the complementary coffee was a plus!"
Cons: "It's not about the flight but it was difficult to know how to use the WiFi at the airport in Munich. The sandwich was so-so."
Pros: "Best crew ever. By far most friendly staff and excellent service."
Cons: "Nothing that I know"
Pros: "When we fly Trans Atlantic, we always hope it will be with lufthansa! Sometimes they use united as a carrier and it us never as good as lufthansa!"
Pros: "Everything else was fine."
Cons: "I had paid for comfort seats ($140) extra. When I checked in at gate I was given another seat assignment (without explanation). It turned out to not be comfort seat, in fact it was the last row in the airplane. Had to get eh gate agent back, which was not fast. She said flight was full and a family had been spread out. I understand, but you can't just bump me from a paid and selected seat to a standard seat, especially on transatlantic flight after paying $140 extra. There was no apology. She went back to gate and little while later came back with a comfort seat. Some people seem not to have shown up as the seat next to me stayed open as well. It was very poorly handled."
Pros: "Food was actually fairly good. We almost missed the connection coming from Denver, but gate crew worked to get about 8 passengers from the DEN flight on the London flight."
Cons: "Of course, the seats were uncomfortable, and it was very difficult to get much sleep."
Pros: "Yes"
Cons: "Nothing. Flight was amazing"
Cons: "Bigger seats the new ones are way to narrow"
Pros: "Comfort"
Cons: "Wifi on klm"
Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."
Pros: "Impressive service... amazing crew, very friendly and professional"
Pros: "Everything works and quick to get to destination."
Pros: "economy plus seats were nice, great movie selection, especially international movies"
Cons: "crew was not friendly, i had to ask for water many times, usually water person walk the aisle. food was terrible. other carriers food were better"
Pros: "KLM never disappoints, the cabin crew was extremely kind and helpful!. The food was great, nice leg room in regular economy class, thousands of movies and tv shows...it was great!"
Cons: "Well there was a LOT of turbulence but no one can control the weather and shout out to the pilot for giving us such a smooth landing a rough weather!"
Pros: "No delay and nice staff"
Pros: "Service is awesome. Food is great."
Cons: "People with short connection are affected by the 15 to 25 minutes delay."
Cons: "Dozens of high school students screaming and climbing onto seats, crew did not intervene."
Pros: "The crew was attentive and the seat at economy comfort was comfortable at the “ok” level. It needs much mor3 to be super comfortable. The plug for the headphones was a mess! It was NOT possible to watch a movie and hear the sound too! I gave up! Not a great offering for the extra dollars..."
Cons: "So many things! Starting with the way assistance in the airport is offered to travellers with mobility issues! This is an important issue that needs to be revisited and changes for better service to be made!"
Pros: "Awful"
Cons: "Everything"
Pros: "KLM staff is great"
Pros: "The crew were really helpful with people who had tight connections because of the delayed flight"
Cons: "I wish they had WiFi"
Cons: "The check in desk was late opening & the carry on luggage size was smaller than advertised on their website, so it had to be put in the hold. Open on time to prevent less stress to travelers & give more accurate information about cabin luggage."
Pros: "Seating is tight. The crew was great !"
Cons: "As we landed we had to wait on the plane for an hour and a half because another plane (Spirit) was in our “parking spot.” This made it very difficult for people and connecting flights."
Pros: "great crew and comfortable flight."
Cons: "sceens in the plane to show map and direction of travel"
Pros: "The crew were amazing and the flight was very smooth."
Cons: "Keep up the good work"

Pros: "Food was excellent, service from staff was friendly, and entertainment options were great."
Cons: "Not a lot of shoulder room being in the middle seat. But it had adjustments options for a lot of other things which were good."
Pros: "The crew was fantastic! Our needs were constantly being met and just about the time you thought you might want a snack or a meal, the attendants were already heading down the aisle. Because of an allergic reaction, I asked for ice a number of times and the attendants were more than happy to meet my needs."
Cons: "The seats were very close together. The trip from New York to Amsterdam seemed a lot more comfortable than the return flight. The food from NYC JFK was better than the food from Amsterdam. The movie selection on both flights was a little disappointing."
Pros: "Smooth boarding, clean seats/plane, nice small aircraft (2 rows x 2 seats each), surprisingly spacious (more legroom than expected - and I’m 6’2”)."
Cons: "About 1h30min delay without an explanation. All other planes in the terminal seemed to take off on time without a problem, without exception (aside from this flight, of course)."

Pros: "I got some rest"
Cons: "unable to charge my phone or watch movies"
Pros: "Food was just fine, movie selection very good"
Cons: "Uncomfortable seat cushions, lights were truned on too early (1.5 hours before flight landed)"

Cons: "They stole my money"
Pros: "My bagage broke"
Cons: "I paid extra fee for extra bagage which was tv and i paid insurance my tv broke and no one responces for it"
Pros: "787 is a great airplane. The 3-3-3 seat configuration leaves enough seat width to be just comfortable in coach."
Cons: "Service from airline host Poorly maintained plane Bad food Old entertainment"
Cons: "Old airplane with not really comfy seats. No outlets for charging devices. Very old entertainment screen."
Pros: "Cabin crew very pleasant"

Pros: "The crew were just amazing, such lovely male stewards! They were helpful and friendly and generally wonderful."
Cons: "The entertainment was quite dated and didn't have new movies etc"
Cons: "Pet was left behind at vacation destination as pet's reservation (made and confirmed through KLM) was not found at check in. Waiting for Customer Care to help get pet home and take responsibility for situation and getting no response. Very dissapointed, considering law suit."
Cons: "Terrible service in flight and customer service wise .. app functionality was below"
Pros: "The crew were really helpful since I am a short person in putting my luggage away in the overhead compartment and attentive to everyone's needs. I am a fussy eater and don't really like airplane food but the food was actually really nice. We was given plenty of snacks and drinks in between meals as well. There was plenty of programmes to choose from to keep me entertained."
Cons: "The seats in economy were a little too small for a 12 hour flight"
Pros: "The staff was fast and curteous."
Cons: "There is not anything to complain about besides the usual discomfort of travel."
Pros: "Everytime she passed she was hitting me or I had to hold my drink so that she wouldn't knock it off"
Pros: "The crew was very pleasant and professional. toilets were very clean adequate overhead space"
Cons: "Very uncomfortable seats in Economy Comfort. Legroom and recline were OK but the seats were extremely narrow. No evening meal and breakfast was minimal"
Cons: "Did not get the luggage from connecting flight from Amsterdan to Basel"

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

TAKE ANOTHER PLAIN

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

The airline has lost my luggage.

Pros: "Smooth flight"
Cons: "More food, more water"
Pros: "TAP always has great team members and crew. They are polite, professional and helpful. The flight itself is comfortable and relaxing; very enjoyable."
Cons: "TAP does not check your bags all the way through if you are having a layover. This makes NO SENSE and requires that you retrieve your luggage from baggage claim, and then check in once more and then another trip through security once again! This never happens in the US - one of the few things we get right. Also, I have never had to board a plan from the tarmac since 1970 in the US - why do we have to always wait for and take buses from our check in gate out to the flight line? And how is this ever considered, "Premium Boarding?" It's like a cattle car. Fix these things and I will sing the praises of TAP forever."
Pros: "The flat bed"
Cons: "The Captain made loud announcements waking you up"
Pros: "The entertainment was ok."
Cons: "Everything else was terrible. From check-in to boarding to flight."
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"
Cons: "Snack at end of flight was good but lunch was not good and the dinner in Executive Class going over was not good"
Pros: "I liked that pillows, blankets and headphones were provided."
Cons: "Boarding was a cluster (mainly because the lines were unorganized)."
Pros: "Correct timetabling and on time schedule Decent crew with high standard service wish you more success and further upgrade in your status to be as you deserve one of the best airline globally..!"
Cons: "Correct timetabling and on time schedule Decent crew with high standard service wish you more success and further upgrade in your status to be as you deserve one of the best airline globally..!"
Pros: "The aircraft was relatively new and well appointed."
Cons: "Service with a frown by half the staff. Took away headphones that I had stowed aside for a later time while taking a nap and gave it to another passenger - on a long haul business class flight. Poor service culture. Outbound flight was terrible. Six hour delay. No apologies. Rude telephone staff."
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"
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."
Pros: "The food and service during the flight was great. Enjoyed the meals and they offered drinks frequently. Complementary wine is also a big plus compared to other airlines."
Cons: "The luggage situation. We were very annoyed that we didn’t get a carry on bag and had to pay $92 each for every checked bag. I travel frequently and have never experienced this with another airline."
Pros: "The crew was really good and attentive"
Cons: "The boarding was a little chaotic"
Cons: "I fee cheated because it is the first time that I have. to pay for luggage. In their website it states that the basic fare allows in check-in bag. They said to me that there are different categories of basic fare, which is not disclosed in their website. Additionally any seat change cost"
Cons: "There was an undisclosed $120 baggage fee. The food was horrible and made me sick. We left nearly two hours late."
Pros: "Punctuality, service and confort"
Pros: "Crew service was excellent, food even hetter"
Cons: "No entertainment, either video or audio."
Pros: "I travel for pleasure a lot and this was my first time flying TAP Portugal. I flew from LIS to MAD and the crew were overall more friendly and smiling than on US domestic flights. The plane was clean and bright. I did not notice if the seats recline. I will be using them for short flights throughout Europe when I return for visit."
Cons: "Flight was so short they rushed us eating the cookie and only water was served that I could tell. Also, TAP has their own boarding check-in wing of Lisbon airport. It was not clearly marked and Eropean arrows pointing up could mean to continue forward, as well as go to upper floors."
Cons: "Horrible Terrible airline Tap"
Cons: "why do they sell their tickets when they know they can not make the connection? little time between the two flights compared to the functionality of the airport. never again TAP"
Pros: "Easy smooth transaction"
Cons: "None"
Pros: "Smooth flight Crew extremely nice and helpful Good snack served (not the usual junk food some airlines give and charge for ) punctual"
Cons: "Nothing to dislike"
Pros: "In flight meal was one of the best I have ever had."
Cons: "Could not choose when to start a movie. If you wanted to watch one, you had to turn it on from the beginning or you would start in the middle. Plane could have been cooler as well."
Cons: "If you're going to charge for a checked bag on an international flight, it would be nice if you made that clear on the ticket purchase. A tiny link buried in the information section "See baggage information for additional fees that may apply" doesn't make it abundantly clear that you're going to be hit with an $85 charge each way (ultimately $380 for my wife and me round-trip). Sneaky and dishonest!"
Pros: "All except for service to handicapped."
Cons: "I mad reservation listing that I needed wheel chair assistance due to walking limitations. Upon flight arrival no service was provided not was it provided on my return trip."
Cons: "Seats are very tight had more room on earlier jet blue flight"
Cons: "Though the weather was fine - no excuse - the flight was delayed over an hour and I lost the connecting flight to Newark."
Pros: "Anything I liked feels inconsequential compared to the bad."
Cons: "My wife and I arrived to the airport for our honeymoon extremely excited. We had been saving for our trip to Italy for months, and we were finally going to get things started. Everything fell apart when we went to check in and we were told that my wife couldn’t use her ticket because she had changed her last name. We were told that there was no way that the name on the ticket could be changed because of TSA regulations. Of course, we were also told that we could have changed the name had we purchased a more expensive ticket. In other words, we were lied to and told the issue was regulation, when really they wouldn’t help us because we couldn’t afford a more expensive ticket. The only help we were given was the pleasure of paying over $1,500 more to get my wife on the flight. I am in the process of trying to get this refunded, but as of now we have paid twice for my wife to fly, and neither ticket has been refunded. We may have accidentally broken a rule, but the only function that rule seems to have is to make us pay twice for the same seat. As of now, I would never fly this airline again, and I would warn everyone away from it. I will update this post if TAP does the right thing by two honeymooners."
Cons: "Outdated movies"
Pros: "Meal was OK."
Cons: "TAP changed our seats even though we had paid extra. They were narrow and uncomfortable."
Cons: "The Lisbon airport is very difficult to navigate; signage is poor, and there are not enough staff on the ground. The waiting lines for TAP check-in are outrageous. TAP policy states they allow choosing a seat starting 36 hours of departure, but the poorly designed website let me book seats, and then asked me to pay; at the airport they also told me I had to pay on check-in to choose a seat. Worst of all, at the gate, the waiting area forces all passengers to wait while standing in a big herd - an hour - while police spot check random passenger carry-ons and perform body checks."
Pros: "Cute meal already waiting for us at the seat when boarded"
Pros: "Attendants were great throughout. Prompt takeoff. Food was good; drink service even better! Best movie selection I've seen on commercial planes. Seat was comfy. I enjoyed the flight very much and will always consider flying with TAP."
Pros: "I was able to easily store my carryon which is the maximum size you can bring in the overhead compartment and store my large zippered bag underneath the seat with still plenty of space for my legs."
Cons: "I would like to see all TAP planes come with a standard entertainment option on the headrest in front of you with the advanced menu option of movies, games, radio, etc. and ensure all headphone jacks are operational."
Pros: "The punctuality"
Cons: "The airplane was small for a 8-9 hours trip, the seat were super small, I'm not a big person and I was very uncomfortable in them, the crew wasn't very nice, the food was a mess the girl next to me was a vegan and they give her a cheese sandwich, entertainment didn't work well there were only 4 channels, comparing to AirEuropa very mediocre and awfull airplane, really I'm from Venezuela and even there the airplanes are better, not worthy the 600$ one way ticket I got."
Pros: "La atención del personal es bueno."
Cons: "Los asientos no se pueden reclinar, muy duros."
Pros: "Crew was nice"
Cons: "Flight from Porto to Lisbon was late. We almost didn't make our flight from Lisbon to Barcelona. Our luggage didn't make the connection."
Pros: "Plane was on time, snacks provided"
Cons: "No reclining seats, no pillows, no entertainment. Very uncomfortable for three hours. Also, made me check my carry on without even weighing or measuring."
Pros: "TAP counter staff helped get seat assignments for knee injury. New aircraft with good video system and comfortable seats in Economy Plus. Crew was helpful. Food OK. Arrived on time."
Cons: "Not TAP's fault, but long lines at customs and security at Lisbon Airport made us run to arrive at gate for next flight. Again, not TAP's fault, but additional security check at the waiting area, opening carry-on baggage and emptying my purse seemed over the top."
Cons: "The seats were not comfortable. It hurt my back."
Pros: "Out of the 100+ flights I've been on in my life. TAP Portugal has been the worst and least professional."
Cons: "My first flight from Madrid to Portugal was cancelled (at midnight) so I had to sleep in the terminal because the bus they provided to the hotel couldn't take all of us. Then my flight to New Jersey was delayed several hours making me miss my next flight to Denver (home) and I had to spend a 2nd night in the terminal. I never received and hotel/food/taxi vouchers. I will do everything to avoid flying with TAP Portugal ever again."
Pros: "Lisbon is a great location to have a long layover, any time of the year!"
Cons: "The customs line for non-EU passengers at the Lisbon airport was absurd..."
Pros: "Great service, spoke English, and offered a meal for the flight! Fantastic, will fly with TAP Portugal again."
