Scores according to KAYAK customer reviews
Pros: "The crew."
Cons: "Fake marketing! They said it will be some snacks for economyXtra, and then 2 hours before the flight sending an email saying that the snakes will be charged! Disappointed!"
Cons: "I paid Xtraeconomy to have some snacks during the fly, and they end up coming with a trolley to pay! Disappointed!"
Pros: "I couldn't take the fly. And no body answer! No by the phone, no body on the airport, no body on Facebook, I can't by the web. I need help and no body answer."

Pros: "The entertainment was ok."
Cons: "Everything else was terrible. From check-in to boarding to flight."
Pros: "Comfort and cleanliness of flight."
Cons: "Both flights did not have any general vegetarian options in snack or main courses. There was no option online to submit a meal request and as booking last minute travel and in a foreign country, it was not possible to contact Air Portugal via phone. If the flight offers snack and two meal options, at least one should be vegetarian to accommodate this common population of passengers."
Pros: "Nothing! Horrible!"
Cons: "I had small carry on And there were nowhere to put them. The cabin for the carry one were full and my carry on had to be placed somewhere else, and knowing I had personal information in my bag. Very disappointed"
Pros: "The crew was really nice"
Cons: "The food and proving more snacks and drinks"
Pros: "Fairly new plane with clean/comfortable seats"
Cons: "Bus transportation to the plane was delayed. People were uncomfortable having to stand in the bus for so long. Then the flight was delayed for 15 minutes due to airport traffic. As the only business class passenger i would have expected to be offered a drink then or even a bottle of water at my seat"
Pros: "Only the on board crew lived up to Tap's normal standard"
Cons: "Boarding chaotic in Copenhagen. Food very poor this time"
Pros: "Boarding in Lisbon well organized but delayed at check in and on the tarmac - 40 mins. Food on this flight good. Crew fine both flights."
Cons: "Both Tap flights delayed, little info'/explanation about this.Boarding in Copenhagen chaotic, problematic tickets holding up the queue with only one staff member. Food on board was so boring and unappetising."
Cons: "Baggage crew broke both our suitcases. Awful crew who was really rude to me when I was desperate for the toilet as seat belt sign was constantly on. Hot flight with hardly any air con"
Pros: "The food and crew"
Pros: "everything from the boarding and check-in process to in flight comfort."
Cons: "No complaints. Good flight. And we were surprised to get a snack pack on such a short trip."
Cons: "Hand luggage weighing queue delayed flight, Gatwick flights delays, missing luggage at Lisbon,"
Pros: "The plane was fairly new, clean, and comfortable seats."
Cons: "A better selection of the main meals in business class."
Cons: "Flight was delayed 1 hour"
Pros: "My eyes were closed and the crew passed by while serving food but did not wake me up. As a traveller I been woken up while food was served or food was kept on the seat tray."
Cons: "Overall the flight was good but I dont know why the crew was like that, and the flight seats ain't comfortable and were to close to each other. I legs wasnt comfortable"
Pros: "We really enjoyed TAP Air Portugal and expect to fly with them again. Comfortable seats, pillow, blanket, and MEALS! Good ones with actual silver! USB charging port at every seat, with a good selection of movies. Great airline for a great price!"
Pros: "Mechanical delays leaving London, missed flight connection to New York, now TAP wants to charge me for rescheduling!"
Cons: "Food timing, displays for video tiny and no selection possivble."
Cons: "Timing of food"
Pros: "The plane was comfortable the free drinks and food and crew were friendly."
Cons: "Can't think of anything!"
Pros: "A short but very pleasant flight and food was served, excellent in every category."
Cons: "Nothing, it was the best short flight I've ever had. The staff were very attentive and did a great job of keeping everyone happy."
Cons: "Delayed by 30 hours with very little assistance, no money or spare clothes. Shocking treatment by TAP staff. Will NEVER fly with them again."
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."
Pros: "In time. Plane half full. Perfect."
Pros: "There was a major problem with my booking and I went through almost 2 hours or stress thinking I would not be let on the flight. This has never happened with Kayak. But it was really bad. TAP insisted they could not book me on as Azores Airlines from Pinta Delgado to Toronto was not booked for me. I had to call bothe airlines. With no help from the desk. I finally got both to confirm and at the last minute was allowed on the flight. I chose this route to have a nice couple of days in Portugal and I will have. But the flight start was really upsetting."
Cons: "I like Kayak. But am very concerned about booking through in the future with this treatment."
Pros: "Everything went according to the timetable, boarding was on-time and we even arrived a bit earlier than scheduled, so I can't really fault the service of the pilots, the cabin crew or the ground operations team. Food wasn't exactly stellar, but clearly a lot better than on most European flights operated by larger companies (Lufthansa, KLM, Air France etc.). The aircraft itself was clean and looked fairly new and well maintained"
Cons: "The seating was absolutely HORRENDOUS. Even though I'm nearly 6'3" (close to 1.90m), I generally never complain about seating space or legroom, even on low cost flights. This particular TAP aircraft, however, despite looking quite new, had some of the most cramped seating ever. Additionally, the trays were minuscule (you could barely place the entire food tray the service during the flight, let alone have another drink at the same time on the tray). Also, on the inbound flight (this was the return one), the seats were fitted with a very simple and clever tablet-holding mechanism, so you could easily watch something on your table while eating your food (from a similarly small tray table). The seat back pockets do not have any material/fabric on the sides, so stored items could easily slip out sideways from the pocket. Shame to have such a good in flight service and to be a punctual airline if you're going to carry your passengers cramped like cattle in seats 'rivalling' the ones on Ryanair flights on 4-hour long journeys."
Pros: "Everything was going well. Confotable seats lovely air hostesses. Food wasn’t so great but I was surprised we even got something!"
Cons: "Unfortunately I had problems at airport security which wasn’t very pleasant!"
Pros: "The crew was nice."
Cons: "Plane was 1hr late. The airlines is not very good at updating the time the flight will leave."
Cons: "It was nice to get a snack but the quality was mediocre."
Pros: "Nothing, missed the connection"
Cons: "No flight to Faro during late arrival from"
Pros: "The drinks were available."
Cons: "The drinks were expensive."
Pros: "everything was fine. nothing specifically wrong or bad."
Cons: "had the same food the third time this week. they could do more"
Cons: "Boarding took longer than expected. Flight was delayed then was delayed a second time once everyone was boarded. Smaller plane than the usual TAP planes, but okay flight."
Pros: "Everything from the custumer service, flight departure on time"
Cons: "Long waiting time for my connection flight but i booked it that way"
Pros: "Clean, modern plane - tightly-packed but comfortable seats. Note: if you travel with a bag with wheels it will be weighed at the gate and those over 8kg will be checked. If you have a heavy bag without wheels, it gets no scrutiny."
Cons: "Odd they didn’t have a terminal gate on their home airport - we were bused from a distant spot on the tarmac to the terminal."
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"
Cons: "Flight was late which seems to be a standard with TAP."
Cons: "This survey is useless. Keeps putting things wrongly and drops things"
Pros: "Refuel was quick and we were back on air in less than 30 min... Wich was great.."
Cons: "Stuardes don't have a sense of what costumer service is.. 6 hour flights and their plain aren't equipt with monitors to watch and entertain yourself Thank God I understood portugués but their translation to English was poor Food was not amazing I've been traveling since I was 6yrs old and I never felt so strongly about an airline... Not even easy jet"
Pros: "Quick... I was happy to be out of there"
Cons: "I was not informed my flight was cancelled until the day of the flight. I was able to get in touch with someone to pay for another flight but the communication was lacking."
Pros: "Space was actually good."
Cons: "Boarding was chaos. We had a little child, but no priority for families with children. Flight was delayed over two hours, no explanation, no apologies. Boarding crew was impolite and unhelpful. Then they had to weight all carry-ons! Crazy."
Pros: "Friendliness of ground and cabin crew"
Cons: "2 hour delay, but nobody at Manchester Airport Kept us indormend. Food on aircraft was poor (basically a coleslaw sandwich). Long drive from plane to terminal. Bags took forever to come"
Cons: "Slow delivery of bags in Lisbon"
Pros: "Only check in and boarding was smooth."
Pros: "It's a direct flight."
Cons: "Everything - the plane was last updated in 1989 (you can still see where the cathode ray screens were bolted to the central overhead bins), the entertainment is laughable, several didn't work - passengers were given choice of putting up with that or getting off flight. A flight to endure, not enjoy"
Cons: "Notification from the Travel agency that I needed to get a Yellow Fever immunization."
Pros: "The crew was kind"
Cons: "Seat space is too cramped"
Cons: "One of my checked baggage was lost."
Pros: "I don’t usually complain, but this was probably my least comfortable flight. Not much that I liked about the flight."
Cons: "Compensation or at least an apology for tv screen and air conditioning not working. The flight was hot and boring."
Pros: "Crew as always with air Canada were very accommodating. Always smiling!"
Pros: "Staff were friendly and helpful."
Cons: "Movie selection was limited although I found one in the lot that I thoroughly enjoyed. As always with Air Canada, you only get the most basic snacks and everything else is extra."
Pros: "New plane in the excellent condition. Leg room in economy not bad. Crew friendly and efficient. Boarding worked well."
Cons: "The main meal was pretty dreadful. Grilled chicken with what I think was mashed potato, but it was difficult to be sure. Watery and tasteless. Accompanied bizarrely by a tomato sauce (which did taste of something). Hard to identify the ethnicity."
Pros: "Really nice comfortable seats, amazing windows larger then usually with new technology. Food was ok. It was nice that crew constantly was offering drinks"
Cons: "See above - seats worn out, entertainment worn out, Crew battling old tired aircraft. Massively overpriced. Bring on WestJet direct to Ottawa."
Pros: "It was a really good flight. They lowered the lights. The plane had these neat blinds for the windows that were shading the glass than an actual device so you could obtain the perfect level of light."
Cons: "Only thing that would be better was a bit more leg room. My knee was hurt the day before on a hike and it kept bumping into the seat ahead of me. I'm only 5' 4" so I can't imagine how someone tall would feel."
Pros: "Every thing expert the food"
Cons: "The food"
Pros: "only The crew inside the airplane and the airoplane"
Cons: "Every one in Lufthansa are so rude expect the crew"
Pros: "Only thing good was the brevity of the flight."
Cons: "The aircraft was dirty and ridiculously cramped. Air Canada undermines its brand by flying planes like these."
Pros: "Beautiful new 787"
Cons: "Entertainment options could be more plentiful."
Cons: "Put on Turkish air landed 12 hrs late lggage still missing"
Cons: "The airline crew keep on pushing back the departure due to bad weather. No discipline while boarding passengers. Delay after landing to open the door. No clear instructions about the delays"
Pros: "I am 6ft 1 / 185cm and the leg room was OK for an economy flight. Food was OK for airplane food. Staff were very friendly. Overall very happy."
Pros: "Clean, friendly crew remembered how we had our tea/coffee from the earlier service"
Cons: "Economy is never very comfortable but was better than a lot of other airlines"
Pros: "Crew were good"
Cons: "Seats were too tight. Entertainment was mediocre"
Cons: "I wasn’t able to check in online and therefore wasn’t able to update with my dietary requirements which meant I couldn’t really eat anything that was given. I was told at the airport that it needs to be submitted 24 hrs before the flight and there was nothing they could do. Really unfair and not on."
Cons: "Flight was delayed My wife and I got separate seats Screen and audio on the entertainment system didn't work"
Pros: "Organised zones for boarding"
Cons: "i am à French National ( France) living in UK. After a confusing conversation from the officer not understanding that I was not travelling to France ( assumption) I was asked to show evidence I had the right to enter UK !!!! I explained I lived there permanently ; I was then asked why French hate English so much!!! To which I explained only narrow minded people would believe so and that the style of her comment were not appropriate . I explained my children were half French half British and that her comment was offensive ."
Cons: "Lost luggage!"
Pros: "The hot dinner was good"
Cons: "The pudding was poor, it was just a wrapped cookie. The movie selection was terrible! Most of the films were very old!"
Pros: "Will use again"
Cons: "Airline food has always been poor no matter which airline you travel. Be more liberal with the drinks trolley."
Pros: "great service from start to finish would use again"
Pros: "its was smooth"
Cons: "Very cramped like sardine tin. Not enough flight info boards in airport and they were hard to read m"
Pros: "Ease of boarding - no long queues. Offer to put hand luggage in the hold with no charge."
Pros: "The plane took off and landed on time."
Cons: "The food was terrible and the staff were in there own world and not particularly polite. Hand luggage was not managed so the bins were rammed. Some people had 3 pieces of large hand luggage. Food was the worse I have had on any flight. I would rather pay and have something edible. On 2 of my 3 flights the staff were so wrapped up in there own life's, they did not manage to finish the safety checks before taking there seat. Overall a poor experience."
Pros: "Pretty standard flight...nice crew, free drink, left and arrived on time for the most part. Liked that I could check in early to arrange a seat."
Cons: "The seats could have been more comfortable. Had a couple knees in my back."
Cons: "I didn't travel with children, but if I had done they would have needed entertaining. The crew offered iPads (to rent) for the entertainment of children and adults alike. Why can these not just be given to passengers, better still BRING BACK SCREENS IN SEATBACKS!!!"
Pros: "Boarding was very well-organised ands clearly explained."
Cons: "USB socket broken and non-functioning. Plastic fork snapped and shed tines. A truly ghastly movie selection."
Cons: "We were walking towards our seats near the end of the aircraft when this flight attendant stopped us from loading our hand luggage in the overhead bins. She made us stuff them under the seats in front of us. There was space im the overhead bin, but there was a bunch of stuff that belonged to the cabin crew. Rude."
Pros: "It was a normal flight. Only one hour."
Cons: "Snack options could have been better, only a biscuit."
Pros: "Everything. The plane was immaculate, the seats were comfortable, the food was delicious, the flight crew was friendly and professional. Air Canada's abillity to transit passengers from the US to international destinations is truly remarkable and must be best in class. I went from an inbound flight from Houston, through Immigration and to the gate for my flight to London in under 15 minutes!"
Cons: "I did not like the crew in Casablanca airport . They were so slow and they did not help the travelers to get to the boarding on time. It seems that they don't even care about their passengers. Air canada needs to improve the professionalism of their crew in Casablanca, and the quality of service provided."
Pros: "Liked everything about this new class of service on Air Canada. Seat was comfortable with good recline that didn't interfere with fellow passengers. Food was excellent, entertainment system was well stocked, flight attendants were friendly and high energy. Even got to use lounge and fast-track security lane at Heathrow."
Cons: "Zero complaints."
Pros: "We did not make it to this flight since it was cancelled"
Cons: "We were rebooked on a flight with a short connection to London and they bumped us off that flight claiming that they could not get our bags in on time. Very poor customer service."
Cons: "See above."
Cons: "Baggage hasn't arrived after 45 minutes"
Cons: "Your worst nightmare. Lost my luggage and 24 hours can't even tell me where it is. Complete incompetence."
Pros: "Reasonably good all around."
Cons: "I paid for an upgraded seat on this flight and wished I hadn't. Whole rows of seats were empty and I would have been more comfortable in my original seating, according to the seating plan during online check in the entire plane was booked out but for a few seats."
Pros: "Overall a good experience. Had to pay for food but it was quite good so I didn't mind. Supposedly the crew were short staffed but I found them attentive and helpful and to be honest I believe the people who complained may have been a little precious."
Pros: "Staff were incredibly kind, courteous, and knowledgeable. I need wheelchair assistance and they handled that beautifully, asking thoughtful questions about my needs and adapting their plans to my answers. They also helped me with stowing my carry-on since I would have struggled alone."
Cons: "Unfortunately, through no fault of the flight crew or gate crew, we got one of the few remaining planes in the fleet that are so old that they can't fit a full carry-on bag in the overhead bins or under the seats. Larger carry-on items had to be checked through to final destination, which made a lot of passengers upset -- either because they were business people who needed to be able to work on the flight, or they had important baby gear in there that they would need before that, or they were traveling far away using multiple airlines and were rightly worried about lost luggage."
Pros: "That even though there is a delay, we still made it around the same time"
Cons: "That there was a delay in the first place"
Pros: "I've always had adequate flights with AC. No one goes over and beyond, but everything is as you would expect. A smooth flight."
