Pros: "Friendly staff, great service on board. Way better value and service compared to the tacky Irish competition flying the route. Delta all the way"

Cons: "I booked tickets via Delta, operated by KLM. They lost both of my check in bags in September, and it happened again today for the same scheduled flights. Had 4 hours of layover and KLM still wasn’t able to manage it."

Cons: "I have ordered Wheelchair for my parents which one of my parent didn't get it on Mumbai Airport. When they arrived on Amsterdam Netherlands Airport they were dropped to the gate assigned first and once the gate changed on the fly no body came to help them moving to the new gate assigned which was far away to walk. Nobody even came to tell them that the gate has been changed. It was because of my father's alertness they didn't miss the connecting flight and when my father asked help to members on airport none of them helped my parents and other 4 co passengers which also were on wheel chairs. It was so scary experience for them that they asked me not to book any more flights with Jet Airways. I won't recommend Jet Airways to any of my friends for their parents to travel to USA. I strongly recommend you guys to take a strict action against this. This is so unacceptable."

Cons: "he had no choice but to look at the closed door of his flight, and wait an additional 7 hours and they didn't even give him a voucher for food. I'm his mother, I'm currently visiting family in Scotland, so couldn't help him much. I'm pretty disgusting and disappointed by the whole experience."

Pros: "crew were absolutely delightful, full of smiles and doing everything to make you comfortable. seats were fine enough and got some work done and a bit of sleep. first lunch was fresh and tasty, but the second, a burger, was edible, but not much more."
Cons: "tv screens are dated so movies are not as crisp as you find in newer planes. you need a 2 prong audio adapter to use your own headphones."

Cons: "I don’t like the limited choice of drinks on these short KLM flights."

Cons: "No proper info regarding cancellation. Staff was unfriendly and abruptly responded to passengers."

Cons: "una valija se perdió. Eso desató el descontrol que tiene KLM para seguir el equipaje. No hay como hacer tracking. No hay un teléfono a donde hablar, la web está desactualizada y con información equivocada. Direccionan a usar canales de twitter y facebook que no responden. Primer experiencia en KLM y no pienso nunca más usar esta aerolínea. Llevar el equipaje o resolver un problema sobre valijas es de lo más básico de una aerolínea y no lo hacen."

Pros: "Nothing"
Cons: "Airlines had no record of our pets flying with. Missed our flight even though we were there over 3 hours prior. Ruined the last day of vacation. Now we are waiting for the promised help in Amsterdam. No one is here. No one knows anything. Feel like crying"

Pros: "Delays and no proper customer service."

Cons: "Taking off late caused me stress because I had transferring flight within less than two hours in transit originally. So we arrived later about 50 minutes so I had to manage my situation and find my next gate and be on time. And an other thing that I disliked was that I was allowed to have only one baggage which was very unusual for international flight between two countenances. And the crew was not polite enough so she made fun of my Cary-on. In short, I expected more from KLM which is famous for them being "Royal" but not acting as one of them."

Pros: "The service of the crew onboard"
Cons: "Entertainment not to many recent movies and the boarding process was a little bit confusing."

Pros: "- entertainment systen was OK (movies), but has no current news - food was good - windows can be darkened progressively"
Cons: "- Schiphol airport (AMS) is small, crowded, noisy; no water fountains; toilets are dirty and insufficient in number; SFO is much better - KLM boarding process was chaotic (not by group or row number), boarding/security personnel (4 old guys) didn't have a clue - 787 is noisy, chairs are uncomfortable (my back still hurts) and very close together, they also recline way too much - food trays not collected promptly - noisy babies on all flights - clearly not enough cabin crew for a full flight - no or wrong info by pilots on timing (crew are always lying anyway) - gate is all around the back at SFO (long taxi to get there) - they inserted people in wheelchairs during deboarding thus holding everybody up."

Pros: "Punctual"
Cons: "They forced me to ceck my trolley because i had a suit with me!!! And the airplane wasn’t even full. Even worst they allowed some pieces of “hand luggage” that were double the maximum allowed size"

Cons: "Flight was delayed for 4+ hours"

Cons: "I may be wrong but these days, the staff curtsy and overall well coming approach is lacking! Just a smile and a few cheerful words can transform passengers’ mood greatly!! This becomes particularly important when one is traveling for > 9 hours back to back flights!! One can extra charge for it!!"

Pros: "Perfectly on time, no hassle, seat OK. This is the way I appreciate a flight."
Cons: "Food. No choice, three "madeleine" (sweet) cookies for all, no sugar-free (salty) alternative..."

Pros: "The cabin crew were amazing and the seats very comfortable, even in economy. I'm not a super comfortable flyer so I loved that the pilot would always warn when we were getting into turbulence. 2 thumbs up. I will fly Air France again"
Cons: "I'd appreciate a better selection of food and drinks, even if I have to pay for the drinks."

Pros: "The crew was terrific."

Pros: "Crew was awesome!!"
Cons: "I paid extra for the seat, but there was a metal box under the seat in front of me that curtailed my ability to stow my carry bag, and my leg room. I am very diappointed that I paid above the normal seat charge as if there was a premium to this seat, but in reality it was a sb par seat."

Pros: "The crew was helpful and accommodating"
Cons: "The flight was delayed, missed connection, and lost baggage. Subpar."

Pros: "Boarding staff helpful with Disabilities; food services quick and pleasant; interior cabin temps appropriate."
Cons: "Why is boarding so prolonged? 1-Small children and elders cannot stand for 20/30 minutes 2-Why are various sections (particularly Economy), no longer boarded by rows. and from rear first...so people don’t clog aisles, step over others, injure or be injured by heavy overhead moves?"

Cons: "Separated me and my wife for the whole flight! Could not accommodate us together. This reservation was made over 6 weeks ago !!!"

Pros: "Food and wine was very good. Music selection was excellent."
Cons: "Not enough leg room."

Cons: "Entertainment screen did not work; in neighboring seat it could not be switched off when we wanted to sleep; sourly employees everywhere (re-booking counter an exception); food close not being edible and cold; I forgot my watch on when going through security in the Air France terminal; when I started to say "sorry" I was yelled at by the screener who said that she will do the talking; she sent me back through the scanner twice without my watch, then once more with the carry-on and made sure that I went to the end of a very long line to wait for another screening rather than having me just go through the scanner without my watch. Needless to say, there was nothing else suspicious about me once the watch was removed. Eager to exercise her power, the security person did not seem to consider that she slowed down a long line of people waiting to be screened. I should add that I am 73 yrs old grey haired female who has traveled a lot both for pleasure and business during my entire life, often to some difficult places and that I do not argue with or provoke those in power in a situation like this. The yelling and the sending me repeatedly through the scanner, which did not beep once the watch was removed, was beyond anything I had experienced anywhere else. The sending me to the very end of the line seemed outright spiteful. (I did miss the plane connection.)"

Pros: "On time."
Cons: "Did not seat together passengers, although booked and checked in at the same time."

Pros: "Haven't flow with Air France for some time now and definitely noticed a lowering of standards"

Cons: "Through my own fault I ordered a different seat instead of window seat. :)"

Pros: "The cabin crew were excellent"
Cons: "We were transported to the plane which was quite some distance to the plane via bus after climbing down steep stairs from the departure gate area. Then we had to climb steep steps in extremely hot weather. We were then delayed for a hour in the plane in very hot conditions as the plane had its air conditioning off and the ground air conditioning was not put on. We were swearing in the heat for an hour!! We arrived at our destination and hour and half late!!"

Cons: "There are always delays. Today it was that internet was down."

Pros: "All crew I interacted with was great, friendly, and helpful."
Cons: "Flight was late. Boarding very slow. Entertainment was ok by today's standards. Each seat had a display, but movie selection was not great. For a French airline I was looking forward to breakfast -- maybe some nice pastries or at least a decent croissant with jam. None such. It was disappointing. Meals were not impressive either, but the complimentary wine was good."

Pros: "Airplane staff were good"

Pros: "Crew was great"
Cons: "Not enough food"

Pros: "Our flight attendant and fnally making it home!"
Cons: "Disorganized uninformed staff. One says I have to have an additional "random" security check after going through the same thing in security. Turns out it wasn't random and I didn't need it. Both times they read my boarding pass wrong thought I was going to Tel Aviv - not random. Airport was hot as hell! Flight kept getting delayed then we had a gate change as well. Finally got on the plane and it took forever to take off so we were basically sitting in a sauna for 30+ minutes."

Pros: "The flight went smoothly from boarding to landing. The crew was helpful, kind, & courteous. I would definitely fly Air France again. Online check-in was also easy to follow and complete."

Cons: "The clarity about baggage fees, really unclear and very expensive."

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

Pros: "nothing - they misinformed me left and right so I couldnt make properly informed decisions and then denied me boarding and told me to pay for a new flight after having spent over 750 and 3 days 2 nights at the airport due to the mishaps."
Cons: "staff that gives the correct information so u can properly plan for the check in and boarding procedures and compassion to advocate to let me onto the flight they made me jump thru hoops just to get onto."

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

Pros: "The new A330-Neo is a lot more comfortable than any other recent airplanes. Loved the space between seats and entertainment is outstanding too. Food was very good and the crew exceptionally friendly."
Cons: "Nothing to complain about. Everything was outstanding."

Pros: "Some on crew lovely. Others terrible, bitter people, not at all suited for customer service."
Cons: "Disgusting food. Price gouging for checked baggage. Surly attitudes."

Cons: "My wife and I paid for a better seat, (online) but when we boarded they told us that was impossible. They kept our money !!!"

Pros: "Good crew. No crying or screaming children is always good. Dinner was decent & nice that it comes with a glass of wine if you wish."
Cons: "Packed in a sardine can for 9 hours is not fun. Being bussed out to a remote location for a wide bodied plane is crazy. At least at ORD we had a gate."

Pros: "Crew was very good. Seats were spacious. Plenty of entertainment."
Cons: "More frequent snacks."

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

Pros: "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: "Check in too long 3 different queues Took too long to open check in Boarding not efficient Flight was delayed"

Pros: "The boarding procedure was much more organized than the previous flight."
Cons: "They served fish on board, and the odor stuck around for awhile."

Cons: "The early morning fight was delayed, and I appreciated that TAP notified me ahead of time. However, TAP did not communicate that despite the 2 hour delay, we were required to be at the airport checkin as if the flight was never delayed - and agent dismissed us as late. Only begging got us on flight."

Pros: "Comfortable seats with nice pillow and blanket"
Cons: "Boarding was awkward and slow."

Pros: "Cod fish meal was nice! Lots of movie options, and the staff were nice."
Cons: "Foot rests would have been great to have. The boarding process was exhausting. A long line for another passport check (after the immigration check point) and the long bus ride to the aircraft."

Cons: "Not missing our connection due to delays."

Cons: "The headphone situation was confusing and no charging ports Fairly comfortable for an older plane"

Pros: "The crew was kind and the flight ok. They wanted to charge me 120.00 USD for my one bag checked ONE WAY. 240.00 USD round trip for one checked bag!!!!! On their website it clearly states one free checked bag for ALL FLIGHTS xcept “discount” fares. No way to prove I purchased “basic”"
Cons: "They lied. The website does not clearly state that you will be CHARGED FOR CHECKED BAGS. Warning!!"

Pros: "The tripulation are very nice people. The food is better last year. Is good."
Cons: "The space between seats are small."

Pros: "Service was good and the food was better than average."
Cons: "Paying extra for business class so you can sleep just isn't worth it with TAP. We had an older plane, showing its age, and the seats did not go completely flat. So, I kept slipping down and my feet jammed into the seat in front of me."

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."

Cons: "poor and cheap plane"

Cons: "Missed, even on time at Lisbon"

Pros: "Frendly"
Cons: "Nothing"

Pros: "The entertainment was good and the food was better than I expected."
Cons: "Bags restrictions without us knowing. Delayed flight but we still manage to get to our destination on time. The same did not happen before where I had to wait until 2am for my tap flight that was supposed to leave at 11:30pm. I have been flighting TAP for many years now and it used to be one of my favorite airlines. No longer is the case. Over the years there has been a decline on service."

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: "When missed connection, airline had vouchers ready — like they’ve done this many times before."
Cons: "In one trip, two flights canceled, and one flight delayed so missed connection. Hard to reach anyone to reschedule or change plans."

Pros: "Seats were nice in the front half of the plane."
Cons: "Checked bag costs are 90USD which is way to high. No meal selection. One choice offered and it was a weird flavor."

Pros: "They solved the problem of my sit. But i almost have a hurt attack"
Cons: "When I get to check my tickets they told me that I was in stand by. I have to fight to get my sit."

Pros: "service,puntuality,guidance"

Cons: "Vegetarian food was terrible, seats were really small"

Cons: "Huge delay. No clear explanation what caused the delay"

Pros: "The crew did a great job."

Pros: "Staff good very pleasant. Entertainment good."
Cons: "Bit late into Lisbon and luggage left behind."

Cons: "Baggage fees were unacceptable. All but one of my group of 12 had to pay and we were not told why. It was not clear that this should have been done via the website prior to the flight and why is it significantly cheaper online? Very disappointing."

Cons: "Tha total absence of hard alcoholic beverages, no moderate cocktails"

Pros: "Efficient friendly generous service To a little used, user friendly airport (Free alcohol, i.e., wines; no spirits) I ordered a Muslim meal: delicious"
Cons: "We had trouble with the A/C leaving; until we were airborne, it was hot. I suspect that this is an unusual problem. In general, I find small international carriers better than the large ones; my favorite so far in Air Austria"

Cons: "The flight was delayed."

Pros: "Very good leg room. Easy pleasant flight."

Pros: "Great boarding process, friendly staff, the planes are newer and well-equipped, everything was on time, good food options on the plane"
Cons: "Nothing!"

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

Pros: "The crew."

Cons: "Paid $130 for 2 extra spac s acts. Didn't have any extra space. Had a woman in front of me who reclined her seat all the way for he whole flight. Had to have on of he crew to ask her to put her sat forward for the food service part of th flight."

Pros: "The service they provided us reminded us of how airlines used to treat their customers in the past. From the customer service to the services provided and the legroom on the flight -- everything was more than what we expected and we would consider flying TAP Portugal again."

Pros: "My first time flying tap and I was impressed. Everyone was friendly and helpful. Planes seemed very clean, and gave me the impression that they are probably well maintained."

Pros: "Food was great! Space between seats was perfect."
Cons: "Nothing."

Pros: "Basically on time and the employees were very efficient and professional."
Cons: "Having to take a very crowded shuttle bus to the plane."
