The four PINS generated by the counter staff did not work. We all took turn to try to no avail. by then we have walked too far from the counter we could not be bother going back. No airport that I've been to had poor internet service connection like this airport, yet it is supposed to be THE WORLD'S NUMBER ONE AIRLINE. We boarded at 11.30pm, last time we flew with them they gave us supper. Last night they gave us only water. We went to sleep hungry till the morning. Since when they started to operate like those cheap airlines that you have to pay for your food? And the night package did not have eye mask.... how could we sleep... ? Singapore airline could learn from Qtar. Very very disappointed."

They supply earbuds, socks, toothbrush and paste."

Pros: "I love traveling on Singapore airlines. They have excellent service and always on time. Their entertainment system is very good. I won't say excellent as I've seem Emirates and they still have along way to go to catch up."
Cons: "They did not give us the landing cards and we had to fill them in at the airport. Many were like us and I am surprised.

Pros: "Really recommended . Wait alittle longer but i got a free tour go around Singapore ."
Pros: "Staff on board were lovely."
Cons: "I asked to be placed in a seat as close to the front as possible as I suffer from motion sickness in the back of the plane. I was placed in the back row all the way to my destination and all the way home. I vomited 8 times and felt very sick. I did notice that there were many seats available in the front of the plane but they are never given out as women with babies and children always get them and then single travellers like myself are made sit in the back. I travel a lot, I usually fly Qantas and they are very good at providing seats closer to the front. I will be reluctant to fly Singapore Airlines again due to the fact that they were not accommodating at all."
Pros: "Seating space was very good. Meals terrific"
Pros: "Crew was outstanding"
Cons: "No sound on my entertainment system"
Pros: "It was convenient"
Cons: "The seats were so hard I had to sit on a blanket and have a cushion behind. The entertainment was poor and the system was old."
Pros: "Overall, the Singapore Airlines team are always professional and friendly. They pay attention to every detail and try to make sure everyone is as comfortable as possible. One of my favorite things about this airline is that snack and juice are readily available throughout the entire flight without bothering the flight attendants, say in the middle of the night. This includes fresh fruit and juice, which in my book is a huge plus. Their bathrooms are always clean and include extra cosmetic amenities."
Cons: "Sometimes I feel like the cuisine is a bit too Asian and spicy. I had the fish curry and paid for it later in the flight in the bathroom, if you know what I mean. Also I was disappointed that I could not continue the same movie on this flight, as my previous flight, despite both flights being Singapore Air and using the KrisWorld entertainment system. I think the movies should be the same on each flight. However, the wide selection was great and I watched something else instead and really enjoyed the music selection."
Pros: "The service"
Cons: "The quality of the red wine"
Pros: "It is always better when this flight is operated by wide body aircraft, as was the case with A330 this time"
Pros: "Awesome cabin crew, amazing food, more leg room than European and American carriers. Amazing price. What else can you ask for in economy?"
Cons: "Food. Lack of vegetarian options in 2nd leg."
Pros: "Very nice love it"
Cons: "Very nice and love"
Cons: "Too warm, chaotic boarding, not enough baggage space, airline couldn’t upgrade me at the gate with miles."
Pros: "I never usually like plane food but liked Turkish Airline meals on all flights I’ve been on so far"
Cons: "I do like turkish airlines but wasn’t happy with this flight. On check in we were left with seats towards the back of the aircraft. The lady seated neit to us in the aisle seat was in a wheel chair so was a problem if having to get in and out. I didn’t think it was fair that a person who depends on a wheel chair sits so far back on a plane. She also had to deal with our crying baby"
Cons: "Connection flight from plane to the gate,seats need to be updated"
Pros: "Excellent service from ticket agents, cabin stewards, etc."
Cons: "Because we were late, my baggage didn't get transferred. I had to ask around to find out who handles Turkish air baggage issues in Tel Aviv. I found out within a out half an hour what would happen -- you had them delivered to where I was staying the next day. It all went smoothly and fortunately I had allowed extra time after I arrived ... no problems. And the people who handled your baggage claims were professional."
Cons: "Entertainment system not operational"
Cons: "Entertainment system didn’t work Seats did not recline"
Pros: "I liked nothing about this flight!"

Cons: "Took them too long to pick up the trash ..."
Pros: "AMAZING AIRLINE. Anyone traveling to this part of the world, fly Turkish!! Best international flight I have ever taken."
Pros: "The service was very good as always with Turkish."
Cons: "Seats are not spaced enough. It is not big enough for a 6 foot 3 male caucasian."
Cons: "same, boarding crew was not friendly, and it took a while for boarding."
Pros: "The crew was excellent, the food good."
Cons: "The entertainment system, in three out of four long flights, did not work. In the one that "worked", the sound was terrible and this made the experience totally unsatisfactory. A major airline should avoid this."
Pros: "including new releases"
Pros: "Friendliness of crew."
Cons: "N/A"
Pros: "Spacious seating, even the last row reclines. Very good service. Free food and drink served throughout - including two warm meals."
Cons: "Boarding was organized but super time intensive. They group you together and then board in groups. Seems unnecessary. Can't they just boarding rows, like most airlines?"
Cons: "Could not board the plane although being at the airport well in advance. Forced to buy additional tickets for enourmously high price. Stay at the airport additional half a day without food and water. No one from the company showed any concern and were of no help. Horrible experience. Never again fly Turkish airlines."
Pros: "The few and very rarely seen employees are not even willing to listen to our questions let alone help us, Ican for sure say in 1 out of 10 wotkers there was only one that was willing to help And did let the one that helped us know I and my co travelers apriciated her or him to me there was one girl who offered me help after I cried because I thougth I would miss my flight to houston. I told her tgank you a 1000 times."
Cons: "Every thing Lack of help Lack of infirmation Lack of annoucement of next step Lack of a simple WIFI so I could let someone know what is happening to me There was no airport free wifi This turkish airline have now lost me as a customer unless I am traveling to somaliya where no other airline goes Bye bye Turkish air I am deeply disappointed at the lebel of the airport serveses For that reason I am done dealing with it and I will let this known to my friends and Family so they also stop doing bussniss with this airline It it my new mission now to stop anyone flying turkish air because of customer serves ... I just glad my horrifying experiance is over and I am home now Thanks for askiking me how was my flight"
Pros: "Nothing."
Cons: "The fact that I missed my connection flight in Thailand because of a two hour delay. I was never informed why there was so much of a delay and in turn I had to pay triple of what I payed before for my flight. Very disappointed. Won't be flying this airline again. Service was rude. They should be more responsible when it comes to timing. We were on the flight waiting for two hours!!!"
Cons: "Had to remind the hostess to bring our meal as she missed us in giving out the meals initially."
Cons: "You could be choose food... one of the dish was only pasta... what about the people who's allergic? I am... The business class crew was very stuck up! Totally looked down at people who wasn't in the business class... The Aircraft has no AC that you could adjust air blowing on you! It was incredibly hot the whole time !"
Pros: "The food and amenities were alright."
Cons: "It left late, the plane lost my friend's luggage for a day."

Pros: "Customer service and professionalism of crew was outstanding. It felt like how it USED to be on other airlines, and even better! The food service was great, and I appreciated the little necessities bag. The travel experience was a positive part of our trip, instead of the usual exhausting drudgery of traveling very far distances."

Pros: "New plane. Excellent quality and quantity of food. Amenity pack, Nice entertainment selection. Good value for cost!"

I really appreciate her kindness, professionalism, and hard work to ensure I was comfortable and that my luggage made it on board. The food and entertainment was great. I really loved the goody bag, it was very thoughtful and included everything to make you comfortable for the flight."
Pros: "Price."
Cons: "I had no (NO) room between my knees and the seat in front of me. I'm a 5'10" woman - I can only imagine what a man over 6' must experience. The lines were chaotic, people pushing from behind to get into position in a line that wouldn't be moving anytime soon anyway."
Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."
Cons: "It was great! Nice job Delta !"
Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"
Cons: "For options none. No drink carts at all. Had coffee once after I asked. Poor quality entertainment. Just a huge waste of money."
Pros: "Christina brown was amazing at gate"
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."

Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Cons: "1.5 hour delay...no reason given!"
Pros: "Love the fact that the head rests move to support your head better."
Pros: "The male crew member was excellent. He was responsive and speedy with trying to find a solution. He gave me a few flyer miles for my trouble and was empathetic, which is rare."
Cons: "The tv/monitor didn’t work so there wasn’t any entertainment for the majority of the flight."
Cons: "No meal option and my video screen volume did not work"
Pros: "The crew was great and super nice!"
Cons: "Screens with games, more leg room, and not having kids behind us messing with tray tables the whole flight."
Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"

Pros: "Entertainment"
Cons: "Boarding at JFK.Always messy"
Pros: "Boarding was quick"
Cons: "No entertainment, plane was small"
Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."
Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."
Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"
Pros: "The seats had plenty of leg room and the crew was was very kind."
Cons: "My seat was uncomfortable and I was seated in the only row of the aircraft without entertainment for a four hour flight. Then on top of that the passenger next to me removed his shoes and you could smell his feet from a mile away but the flight attendants never requested for him to replace his shoes."
Pros: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"
Pros: "The staff really helped me out getting on standby so that I didn't have to wait for a 9 hour layover. Overall great experience and great staff."
Pros: "In a pinch they were able t"
Pros: "Great in every way"
Pros: "Excellent piloting and cabin crew."
Cons: "Check in lines were crazy long"
Cons: "My daughter was stuck in SLC for 5 hours because there 1 cancelled flight and 1 delayed flight. It was very upsetting not knowing when she going to arrive in Denver."
Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"
Pros: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."
Pros: "really helpful and friendly service and nice seats."
Pros: "free texting and entertainment!"
Cons: "our flight was delayed half an hour."
Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Cons: "Excellent service excellent pilot"
Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."
Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
Pros: "Entertainment"
Cons: "This is my third flight this year with Delta and every time we wait for the "crew" to get off from another flight. And as soon as they get there we can board. It's getting very annoying. Fix it."
Pros: "Early arrival. And service"
Cons: "I was assigned very last seat and there is no reclining option."
Cons: "long wait and delayed flight"
Pros: "WiFi, good flight attendants"
Cons: "Would like to see Direct TV along with Delta Suite so can watch live TV"
Pros: "Attendants and entertainment"
Cons: "Delays for no explained reason"
Pros: "One male attendant from the first class cabin - super sweet and attentive to our needs even tho we're not seating in the premium cabin"
Cons: "Junior attendants in economy comfort seat - so lazy and whiny!"

Pros: "This Transavia Airlines is not good at all."

Pros: "The plane size & comfort was excellent. The staff were very friendly"
Cons: "N/A"
Cons: "The only complaint I had was that it was very warm on the flight (and I usually get cold on flights), and in the seats we had there weren't fans above the seats. A few rows up they had fans, so apparently you have to pay extra for air... This wouldn't be a big deal on a short domestic flight, but for an international flight it was a long time to be uncomfortable!"
Pros: "KLM are our airline of choice. A great full-service carrier with impecable standards."
Cons: "Nothing"
Pros: "Food was great, enjoyed watching videos, staff very profession and friendly."
Cons: "Boarding was delayed and prolonged My Baggage was not transferred and was not available when I arrived in Dulles."

Cons: "Don’t be late"

Cons: "Staff hurrying us up 40 minutes before departing and threatening to take our bags out of the plane in case we didn’t board then. I had to leave my coffee and run."
Pros: "the trip was excellent and comfortable. LOved the windows that shaded out rather than the having to pull down the plastic blind. entertainment on board top notch screen huge One hostess , Helen was absolutely fantastic and the best I ve had on my many trips. I will recommend KLM whenever I can"
Cons: "the headrest is hard. Apart from that- all was fine"
Pros: "Checkin 1a at Schiphol had long lines, and no seperate counters for just bag drop. My family and I had to wait for 50 mins, to do a bag drop which in,y lasted 1 min! Flight was delayed, without proper announcements."
Cons: "Seat pitch could've been more. At least let us know via Whatsapp that the plane is delayed, or at which belt the bags would come out. This basic info was lacking."

Pros: "Awful"
Cons: "Everything"
Pros: "Overall KLM experience is good"
Cons: "Food quality was mediocre for a business class flight."
Pros: "Crew was nice and friendly"

Cons: "when serving drinks, cabin crew limited to serve liquor only once and it was poor service."
Pros: "The service"
Cons: "The seats"
Pros: "Seat 39A did not recline. The gentleman next to me spread his arms out a bit as he typed on his computer the entire way. So I did not get ANY sleep. Plus he got up at least four times."
Cons: "Except for the man next to me - great!"
Pros: "punctuality of boarding and flight time"
Cons: "attitude of crew in business class: no sense of true hospitality"
Pros: "I bought the Airport tickets for my Russian friend. However customs would not allow her to board the plane unfortunately. That's not Kayaks fault. I would definitely book with Kayak again. Many thanks."
Cons: "KLM lost my luggage during the layover. My luggage didn't arrive even after the next flight to Prague. Customer service wouldn't give me any idea what flight my luggage would arrive on, nor would they tell me what time my luggage might be delivered to me."
Pros: "Wifi on Board"
Cons: "Nothing"
Cons: "Our two hour connection in Paris became 30 minutes because Air France was late in leaving Washington. So our luggage didn't make to to KLM to Amsterdam. My poor rating was because the luggage handling was really poor. Lots of flights from Paris to Amsterdam (almost hourly), but my bag showed up 12 hours later. My wife's bag took 36 hours. And yes, we checked in together. There were lots of confusing messages"
Cons: "infotainment was down. Lost my luggage the flight was delayed"
Pros: "Nice crew; clean plane; decent dinner"
Cons: "No entertainment system; insufficient knee space"
Pros: "I enjoyed the attention to detail and comfort. Helped to make the flight easier to handle."
Pros: "Food was good and crew members were very nice"
Cons: "My check in luggage was in very bad condition when I receive it. My clothes were all wet and they got bab by each other’s colour. Many clothes are not in a condition to wear now. Those were expensive and I had a big loss because of that."
Cons: "After more than two hours of delay... Initially the flight takes off was at 8:35... Then 21:20... Then 21:50... Then 22:10. Finally we took off at 22:40... Refund our money klm..."

Cons: "Boarding was a free for all. The travelers did not pay attention to the priorities."
Pros: "The staff were professional and friendly The food was very good and plentiful The inflight entertainment has lots of choices The bathrooms remained clean All in stark contrast with BA with who I did the same flight 2 weeks ago and all the above points were very poor"
Cons: "Nothing"
Pros: "Clean airplane, friendly crew, no rush, nice snacks for a short one hour flight. Just generally a positive experience."
Pros: "Equally friendly crew and experience. It was complimented by the time we got to spend in the fantastic KLM lounge while we waited for the flight."
Cons: "Nothing!"
Pros: "The staff at the front desk for the check-in were extremely helpful. I had a complicated issue with my luggage and they helped me to sort it out in the best possible way. Amazing service! Furthermore, the entertainment on board is great! Nice movies, nice food, friendly flight attendants, etc. They even offered me a second sandwich =)! I truly loved my experience with KLM."
Cons: "suitcase didn't turn up, although connection was quite tight"
Pros: "That we didn't crash"
Cons: "Being delayed and missing my connecting flight. No entertainment onboard (for hours and hours)."
Pros: "Flight attendants tried their best given what they had to work with."
Cons: "They can not retire these old Boeing 747's soon enough. Due to mechanical problems, our flight arrived at LAXfour and a half hours late and further problems with the cargo door caused an additional one hour delay of our take off."
Pros: "Nice, turbulent-free flight. Food was good, service with a smile. Leg space was OK because Boeing 777s are usually better at this."
Cons: "Flight left over an hour late because of a sensor glitch. It is concerning when a technical glitch happens. But, the flight was smooth."
Pros: "We love the flight all the way"
Pros: "Much more civilised for the same cost (or less) as the budget carriers. Proper food and drinks included as is the norm with international flights even though it's a very short haul."
Cons: "The stinky guy behind me, but that's not the airline's fault."
Cons: "The flight was very delayed. We sat on the floor because there was not enough seating. We eventually had to squeeze into buses and drive around the tarmac to find a plane. We lost 5 bags in the process but eventually got them 2 days after arrival. the bags did not show up when we originally were told they would."
Pros: "There was no flight! So it's one thing that you have to cancel the flight because of fog; but rebooking us the next day on a flight through New York that doesn't exist, was way below the standard of care I would expect from any airline. Apparently, the NY to LAX flight that KLM booked us on, was only one leg of the flight to Sydney Australia; and according to some airline agreement, only Australian nationals are permitted to take that flight! Running around at JFK from terminal four, to terminal seven, to terminal eight, back to terminal four, to get a flight out, was a bit much considering how tired we were – not to mention hungry, since KLM neglected to provide the kosher meals we had requested with plenty of time – BOTH going to and returning from Europe."

Cons: "Movies available weren't to my taste, which isn't important anyway."

Cons: "NA"
Pros: "There werecseats available at gate area to wabit for plane."
Cons: "Airport overcrowded, checkin at Austrian Airlines horrible - one agent quoated 117 Euro for oversize suitcase when fee was actually 50 Euro. (Note: same suitcase accepted by Lufthansa without extra charge. Security check also excessive and bureaucratic without giving sense of better safety."
Cons: "I had a weelchair and nobody assist me in Viene in Austria And I lost"
Pros: "It was a total nightmare all Austrian flights they put us on were canceled !!! We did not leave Vienna for another 7 h a total nightmare all planes had technically difuculties !! Austrian airlines had total chaos !!!"

Pros: "Crew was wonderful and spoke English They brought drinks. Seats were very nice and plane seemed new and very clean They handed out card decks to the kids."
Pros: "it was mess, so I cant say positive thing"
Cons: "Well, it was all messed up by kayak and priceline. I clearly stated in your search engine I want flight with checked baggage, for which you gave me results. What a unpleasant surprise at check-in to find out it was super expensive airticket with only 8 kg of carry on! You are confusing people on purpose, I cant believe your service!

Pros: "Crew was nice and very accommodating. Food service timing was good. Restrooms serviced every one efficiently. Electronic service outlets are quite helpful and thoughtful."
Cons: "Only at boarding we were notified to be TSA screened, we ended up the last passengers to board and caused flight delay... Electronic check in did not provide food selection, specially for individuals who suffer some food allergies... Boarding process to be revised taking in consideration last minute matters to be better coordinated."
Pros: "Timing flight people working very nice and hospitality"
Cons: "Na"
Pros: "Enough legroom for economy"
Cons: "Basic food - poor in fight entertainment"
Cons: "Food is appauling!"
Cons: "I sat in the last corner seat on the plane... very cramped as there’s no leg room, no window & was overbooked."

THER FLIGHT 599 NOT ON THE BORD. AT THE HEAD OFFICE OFF THE OSTREIN CCOMPANY IN GAT G TELL TO WAIT. HALF HOUR LATER STILL THE FLIGHT NO ON THE BORD AND I RAN EAGEN TO OFFICE OF OSTRIEN END NOW THEY SAD IT`S MESTEK AND I IN GET F . NOW WE MAST MAKE THE SECURITY CHECK OVER AGAIN .

Cons: "Food was crappy and there was no entertainment on board at all. Also, crowded seating."
Pros: "1st class should board last, it just makes mire sense for a lot of reasons. Also 8kg carry limit is rediculous and loosely enforced. We were clearly selected to check our bags. There were others with bags heavier and larger than ours that were permitted to stuff them in their overheads."
Pros: "The crew worked so hard and were always ready to do more for any problem that arose, be it, mothers with babies, the elderly and infirm, the less than gracious occasional passenger, or younger children. The entertaining things on the individual screens also helped make the long periods of sitting more manageable for young and old."
Cons: "I didn't like how the passengers in general, left the cabin of the plane in such a mess! The crew came through several times for refuse, so I couldn't understand. Leaving pillows and blankets should be the only thing to clear out. Maybe a note on the TV screen could say, "a tidy plane helps flights be on time :-)""

Pros: "The flight was good, the food was good, the crew was excellent"
