Airline reviews

Pros: "Nice crew"
Cons: "Comfort. Seats were very uncomfortable with absolutely NO leg room. I fly a lot and this was one of the WORST leg room experiences I had."

Pros: "The crew was amazing and effiecent. Had weather delays, bag got left, but got it the next day."

Pros: "The crew was outstanding and the good choices were excellent"
Cons: "The flight was late( not their fault) and there were several technical difficulties with the A/C and entertainment system"

Pros: "The boarding was fast."
Cons: "For starters our cabin crew were the worst. The first service I had ask for a snack and no napkins. Dinner service was like just chucking food down in front of you. Then a stewardess looks me dead in the face and passed me for the drink service, then she said she thought I was asleep."

Cons: "Getting home 5 hrs later than planned"

Cons: "Good overall"

Pros: "My flight was canceled and Virgin Atlantic gave us a free room in the hotel Ramada. My next flight was at 18:55 and I asked Virgin Atlantic agent am I allowed to stay in the room until time for my flight comes, he confirmed yes and gave me breakfast, lunch, and dinner voucher. However, next day around 12 I got call from Front Desk that I have to leave my room right away because it's time to chack out and If I want to stay longer I have to pay. I called Virgin Atlantic agancy again and the agent run my information and said to me I can stayin the room longer. After that I called front desk to confirm that but they said they didn't hear anything from Virgin Atlantic and I have to leave the room by 1pm. All of this was really unpleasant!"
Cons: "I didn't like anything. I didn't like the communication between Virgin Atlantic with travelers, communication between Virgin Atlantic and hotel Ramada. Everything was really poorly."

Pros: "Smooth overall. Food mediocre but edible. (More than I could say for other airlnes.) Price also good."
Cons: "Lots of flight schedules changes. Missed connecting flight as a result. No time left to deal with customs and baggage."

Pros: "Fabulous flight, light on passengers, so excellent service given by the crew. Virgin goes the extra mile on service and little perks. 747-400 planes also very comfortable, compared to the Airbus 320,"
Cons: "Nothing. Trip both ways were outstanding."

Pros: "The food was great. The flight attendants were very courteous and took excellent care of all passengers"
Cons: "Long flight lol j/k can't help that. It was a great flight, no complaints"

Pros: "I loved the in flight entertainment, and there was always so many snacks and drinks available for free!"

Cons: "There was nothing to dislike on this part of our trip with Virgin Atlantic."

Pros: "Lots of leg room, even in economy."
Cons: "Entertainment choices were a bit sparse."

Pros: "Staff. Very couteous.polite. friendly."
Cons: "Good.entertainment choices."

Pros: "The ground staff was on top of it and the boarding process was smooth, but the cabin crew was brilliant. I’ve never had such pleasant service on a western airline. Well done. Entertainment system is top-notch, and the food was acceptable."
Cons: "The booking process and paying for luggage is disappointing. Plus, I paid a $90 upgrade and just moved up two rows in the same section. Sneaky."

Pros: "Crew were great"
Cons: "Uncomfortable to sit for eight hours"

Pros: "Entertainment Meal service and quality"

Pros: "Legroom, lovely staff and all round good flight"

Pros: "The crew and food were excellent. A little more space between seats would be appreciated. The entertainment equipment was not intuitive or easy to operate. I still feel the airline did a great job getting us to London on-time and a pleasant flight."

Pros: "Good Service. Great attitude of flight attendants..early arrival. smooth flight."
Cons: "despite purchasing 'extra legroom' seats, it was still very, very crowded and tight."

Pros: "Nothing really!"
Cons: "I was coming from Sydney and I have to hurry up to take the other fly to Newark and didn’t have time to buy for nothing to eat but I was very surprised they didn’t offer me anything on the plane and when I ask they I have buy it online and didn’t have many choices anyway, I very disappointed with this fly."

Pros: "Quality of service was good in the plane"
Cons: "Not many good recent movies / shows on in flight entertainment. Food was okay. But, the quantity was too little. It took a really long time for a second boarding pass check at London airport. Other airlines don't usually ask for a second check in"

Pros: "The crew was excellent. Flight was quite comfortable. Nice attention to service"
Cons: "I would have appreciated another round of hot drinks."

Pros: "food was good, and tvs in the seats."
Cons: "wifi didnt work, was the whole reason i took this airline. most international flights are cold it was very hot"

Pros: "I was selected for additional screening at the gate. I have no problem with this at all. From the start I told them I am traveling with my fiancee. They tried to hold me back in a separate area after the screening and I once again told them my fiancee was waiting for me. One staff memeber walked with me half way back to get her and then disappeared. By the time I found her and came back, the staff memeber was no where to be found. Now we had lost are spot in the line and had to go to the back of the line. We spoke to 3 different staff people about what was going on and everyone said, oh the guy over there will help you. But no one did. The staff had No idea how to run a security check or handle paople. There was No working wifi! There was no tvs in the seats, only the old style in the aisle. The staff told me the plan was going to retire at the end of the month. The food was more for animals then for humans! We got updates by txt 10 mins before the staff updated the gate on our flight out from SFO. I have traveled all over the world with a lot of airlines and Never had such a poor service, but what is it to expect. It was United after all!"
Cons: "Refund of the whole flight."

Pros: "Virgin atlantic is the best airline with Dreamliner"
Cons: "Nothing"

Pros: "Fast check in Fast security line Upper Class Clubhouse Fast boarding Excellent onboard service Great crew"
Cons: "Old entertainment system Although the seats can be turned into a bed they don't fully recline"

Cons: "Very small leg room"

Pros: "Staff!"
Cons: "Food was awful. Sorry. Breakfast was unrecognizable. Landed hungry."

Pros: "Efficient service"
Cons: "Entertainment screens were of poor quality"

Pros: "The flight was on time."
Cons: "The floor at our feet had been spilled on during a previous flight and not cleaned. Bag was lost and not returned for 5 days. Crew during flight was flippant and disinterested in service...unless you were Economy+."

Pros: "The movie selections and comfortable headsets made it possible to watch three movies uninterrupted. The food selections were well prepared. Flight attendants were helpful and efficient."
Cons: "Boarding is always a bit of chaos when our seats are right in the back. People further up insist on boarding early and block the aisles in the process. Multiple levels of passport control and baggage checkout are chaotic, but that's for most all flights coming into USA? VIrgin/Delta handled it well enough. By the time we got through passport control in Boston ur bags were waiting and we had no problems at all."

Pros: "Just the food and boarding was fine."
Cons: "Everything else was bad. I think crew were a little rude!"

Pros: "Very nice staff"

Pros: "Friendly, helpful, efficient staff on the ground & in the air. Great selection of movies, tv, music for each person flying. Comfortable flight. Great beverage & food choices."

Pros: "nice new seats"
Cons: "The entre food top was torn, apparently opened before I got it, also there was no salad dressing. ATTN RICHARD BRANSON: Are you concerned for our environment? The head stewardess would not refill my sports water bottle after I asked her nicely, instead she poured water into a cup which she threw away, wasting plastic unnecessarily. I told her I did not like wasting plastic and she appeared to not enjoy what I had to say. This was the same lady who handed me my dinner. Rest of crew was great."

Pros: "There are lots of relatively new movies to choose from."
Cons: "The complimentary headset breaks easily. Tray table was broken and they can't fix it. Very small bathrooms, knees almost touch the door when sitting down. Food selection for dinner ran out quickly, resulting in only 2 choices and one is hot spicy, so basically only one choice. All beverages are given out in small cups, even water is given out in small cups increments (finish in one gulp), they don't even give out small bottles of water. No complimentary packet (eye shades, socks etc.) , not even a barf bag for collecting trash."

Cons: "Entertainment system was good, and I felt that you appeared to have more leg room in economy than other airlines."

Cons: "If the luggage fees were to be included in the price, I would have gladly chosen Emirates for its comfort at that price."

Pros: "Very courteous and professional crews. Clean and comfortable plane. Pilots handled delay and weather superbly. Dinner was delicious."
Cons: "Dinner was great but could have used more snacks. Breakfast was ok. Movies were dated but okay."

Pros: "Crew was awesome and their service was great. I liked that they put snacks like fruit out to eat during the flight."
Cons: "The meals were terrible. I flew on VA a couple of years ago and the food was very good but it has really gone down since then."

Pros: "nothing"
Cons: "this is not an airline, this is a bus company"

Cons: "Watch out for checked baggage fees on short haul international flights. If you buy their saver fare, VA charges you $130 to check a bag at the check-in counter. Highway robbery in my opinion! Make sure you add a bag beforehand. Corporate greed at its worst."

Pros: "Flight attendants were nice."
Cons: "Was denied the seat with extra legroom that my husband had paid for. One of my suitcases (zipper) opened on the conveyor belt, maybe it was tossed?"

Pros: "Very professional crew throughout."

Cons: "Why are there no plug-ins?! That was very disappointing..."

Pros: "It was a great experince we enjoy the flight other than the delay on the luggage"
Cons: "one of my luggage was lost and delayed for 2hrs. We waited at the Airport for the luggage to arrive."

Pros: "There were lots of choices of movies. The flight was only half full, so I got two seats together to stretch out."
Cons: "The cups for water and juice were very small."

Pros: "Great service, tons of food"
Cons: "This VS007 flight is in an old Airbus that needs a major overhaul, especially compared to newer planes in their fleet. The screens are hardly visible, the movie selection more limited, the seats old, and no electrical outlets for a 11hr flight is just not acceptable these days!"

Pros: "Crew. Food wasn’t bad."
Cons: "Late leaving. Waited an hour in Joburg before we could deplane. Cramped seat (normal on most airlines)."

Cons: "Didn't happen. My first leg to Athens was canceled which created a humongous headache since it ended up canceling my return flights. Air Canada had to put me on completely new flights there and back. I think this has taught me to go directly through an airline. Justfly was not helpful. Neither was Turkish airlines."

Pros: "Entertainment system was great. Plenty of movies, games, & tv shows available. Food was good - two full meals during 10 hr. Flight to and from Chicago. Seats, even in economy, were comfortable. Was very happy to learn that baggage would be checked thru to Denver from Athens, even though plane changes were made in Istanbul and Chicago. The two bags did not make the Chicago/Denver transfer, but were on the next United flight an hour later."
Cons: "Boarding process in Athens and Istanbul was confusing. Although boarding groups were assigned, none were used that we could tell. Just mass lineups, with little or no organization that we could see."

Cons: "The flight was delayed from Athens by 1.5 hours. Crew assured us we would make our connections. When we landed no info was given. No announcements made. We were forced to clear security again, even though just transferring and, after running to our gate, found the connection had left and the gate was abandoned with no one to tell us where to go or what to do. The lack of communication and information was appalling. Most people eventually found their way through the airport to a desk that booked them on a flight the next day. It was exhausting and the Turkish staff were unsympathetic."

Pros: "Crew was friendly and efficient. We were served beverages and a tasty (by American airlines standards) sandwich on the less than 1 1/2 hour flight"
Cons: "Boarding was slow, late and somewhat disorganized."

Cons: "There were some passengers didn't allowed to get on a flight because of over booking. Some of them didn't speek English and didn't understand why thy have to stay in the airport.On the other hand I saw how the officials laughed at him because he tried to fight for the place on the flight by using a foreign language. It is an ugly phenomenon that does not respect people"

Pros: "Everything is perfect."
Cons: "Nothing"

Pros: "Crew,boarding,comfort,entertainment and food."
Cons: "Nothing"

Pros: "Great food, good selection of movies."

Pros: "excellent service, nice crew, seats are comfortable no complaint on that front Airport check in crew very professional attitude and cooperative I had no glitch whatsoever the whole journey starting in Los Angeles Luggage was promptly taken care of upon arrival"
Cons: "Honestly I have no negative comment to mention All went well I would fly Turkish Airlines again and again"

Pros: "Perfect trip, seats comfortable and soft even in economy and having personal entertainment was a pleasant surprise. also good selection of films. Food was just a sandwich but better quality than other companies."

Pros: "Food from Cape Town to Istanbul was very tasty and juicy. Yummy."

Pros: "Turkish Airlines offered the best connections to Athens at the best price. Connections were very tight and coming and going worked because the planes were absolutely punctual."
Cons: "I had to check my laptop (not the airline's fault) and the procedure was more tedious than I'd like."

Pros: "Slippers provided, many passengers used these (which is much preferable to feet out on the plane). Enternainment included a good number of recent releases, and food consistently exceeded expectations. Staff was pleasant and accommodating."
Cons: "Consistent line for the bathroom, very little lights off time to sleep (I was unable to sleep on the flight), standard small child kicking the back of my seat and yelling."

Pros: "the food was very good & unexpected on these short flights"
Cons: "they let people take extra overhead space"

Pros: "Plenty of legroom Friendly staff Excellent food Seat was comfortable with plenty of leg room"
Cons: "Even though Turkish has a clearly outlined boarding process on their boarding passes, boarding announcements were so unclear that boarding was just mass chaos"

Pros: "The staff, food, hospitality, & professionalism is 5 star. These guys should train every airline in america."

Cons: "Luggage was held back in Istanbul. It was broken into and never made it to NYC. They shipped to Texas at which point it had been opened and rifled through. Unprofessional."

Pros: "Good overall service"
Cons: "The staff could've been more patient"

Pros: "Food was tasty and diverse"
Cons: "The entertainment system on the flight did not work."

Pros: "Travels was safe and everyone offered you support to anything you needed"
Cons: "From economy to business class and even first class travel...everyone looks to make your travel experience safe and fun"

Pros: "Very professional, clean and excellent service, I will flight with them again"

Pros: "Courteous and efficient crew."

Pros: "Hey, two checked bags free, free in flight meal and drinks including alcohol, free in flight movies and music, free headphones, free blankets, and a free toothbrush, yea toothbrush, its like flying in the way way back."
Cons: "The check in lines are very very long and take forever"

Pros: "Everything was top notch.. the food, the service, the overall experience."

Pros: "Newer plane"
Cons: "Boarding process was very unorganized and slow. People were allowed to act like cattle rushing the gate."

Pros: "My seat was comfortable, the food and drink were good. In flight entertainment options were plentiful and satisfactory."
Cons: "Boarding started on time, but took far longer than necessary. Plane took off an hour after schedule which caused us to have to sprint through the Istanbul airport to meet our connector. And once we arrived in final destination, our baggage never made it onto the connecting flight.."

Cons: "The sears are so uncofortable. Leg space tragic!!"

Pros: "Good service. Food was very good. Roomy seats and very good in flight entertainment system. Made the 12 hour flight very comfortable."

Cons: "I was not allowed the cancel my flight. I lost a lot of money and I will never book through or fly Turkish airlines again. They were rude and had terrible customer service."

Pros: "Flight attendants were so kind, timely, tried to answer my questions to the best of their ability, and courteous."
Cons: "I wish economy had bigger seats, gave out bigger pillows, had more leg room, and had more room to shift seat backwards to sleep."

Pros: "The crew was friendly and I enjoyed the entertainment system. It was a clean plane and undoubtedly newer than most."
Cons: "The food was mediocre, but I was happy to even receive food on a short flight."

Pros: "THE CREW"
Cons: "TIME FROM ONE TERINAL TO OTHER TERMINAL TOO SHORT"

Pros: "There was a terrorist bombing in the IST airport the day before, but our flight still happened, with no evidence of destruction at Istanbul."
Cons: "There was a problem getting my "walker" upon arrival, but Turkish Airlines provided a wheelchair right to the baggage claim area. Very nice service!"

Pros: "I was able 3 soccer games live during the flight. Food was also very good."

Pros: "They had really friendly staff."
Cons: "The leg space between the chairs was really cramped."

Pros: "Turkish airlines is very accommodating and even fed us on this short flight."
Cons: "They tend to generally don't keep their planes very cool and it gets a bit stuffy at times. In economy class, not much leg room as with most of the planes these days."

Pros: "Nice onboard entertainment system"
Cons: "Extremely rude flight attendants. Did not care at all for customer service. Do not expect western standard service ! Service is 3rd world."

Pros: "The service is amazing Food is great"
Cons: "Boarding was interesting"

Pros: "Price"
Cons: "Worst airline I have flown, avoid if at all possible. We saved $400 each on a long haul flight from LAX connecting through IST and we should have spent the extra money. Flight attendants are extremely rude, not helpful, the food is terrible, the planes are all old Boeing 777-300 likely purchased second hand and seem to be falling apart on the inside. I saw flight attendants kicking, punching, and body slamming carts and other items to get them to fit in their racks in the kitchen areas, I hate to think what that means for safety of critical items. Just stay away for your safety and sanity"

Pros: "Good food great passenger service."
Cons: "Disruptive child in seat in front of me"

Pros: "Very professional and helpful crew, food was above what was expected, and even during my short 1.5 hour flights to and from Athens from Istanbul, we were fed meals! I felt very safe and well-taken care of. I will fly Turkish Airlines wherever I go! Çok teşekkürler!!"
Cons: "Smal seats, little leg room."

Pros: "I liked most of the processes but only boarding process was complicated."

Pros: "The Turkish Airlines Boeing 777 was beautiful. And so was the cabin crew and the service they provided. Entertainment System was fantastic. TA puts U.S. airlines to shame."
Cons: "My connections in Istanbul (which is huge) were a little chaotic and stressful. Most flights seem to be deplaned are boarded using transit busses - didn't really care for that - but the international terminal was pretty spectacular. Though there weren't enough places/outlets to recharge electronic devices and finding free WiFi was tricky - finally found some in a nice little cafe! Overall, I'd rate IST 4 Stars outta 5..."

Pros: "Nice short-ish flight. No major issues."
Cons: "Headphones. Lack of entertainment options on this leg of the flight."

Pros: "Very pleasant and accommodating staff."
Cons: "Very short flight. The meal service, while very good was quite rushed for the short hour flight. I barely got my food before the trash came around to be collected."

Cons: "Baggage handlers in IST threw the bags from the plane so hard onto the cart that they bounced. It's amazing that only one item broke in my bag."

Pros: "There was nothing about this flight that was enjoyable."
Cons: "Jammed into a 737. The only saving grace was the short length of the flight."

Pros: "Food"

Pros: "The worst"
Cons: "Everything"

Pros: "Food was great. Especially the ice cream."

Cons: "Better screens for in-flight movies. More legroom or upgrade options."

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: "Boarding from back to front. Making early boarders wait to the side when they tried to embark too soon."
Cons: "All the people standing in line prior to boarding."

Pros: "Love the built in tv’s with free entertainment."
Cons: "The plane got delayed on the runway and the shut the engines off so the plane got super hot, but even after we got up in the air it never cooled down. Normally I’m freezing on flights, but I just sat sweating this whole flight. It was terrible."

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: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."

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: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"

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: "Love the inflight entertainment and the usb plug for phones. Flight left on time and go in a little early"
Cons: "Did not love getting charged $2 for headphones and the girl sitting next to me getting them for free. Super annoying"

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: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."

Pros: "really helpful and friendly service and nice seats."

Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."

Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."

Pros: "The boarding process in Atlanta was as smooth as could be expected given that it was a full flight. I appreciated the gate announcer's suggestions to everyone about how to ease the overhead baggage crunch."
Cons: "Economy is very tight quarters."

Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"

Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."

Pros: "2 hour delay.. had requested when I originally booked the flight an isle seat. I did not get it. The flight was long and uncomfortable."

Cons: "Excellent service excellent pilot"

Pros: "Attendants were courteous quick and attentive. On board entertainment was awesome. Kept us fed with main course snacks and beverages throughout. Made a 10 hour flight bearable."
Cons: "Music selection available was seriously lacking but the movies and games made up for that. Also Air France going into Greece was not as good. Seats had a gap between seat and window, food left much to be desired and service was not as courteous as delta's."

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: "I love the new snack choices! Way to go Delta for offering Kind bars now!! This is awesome."
Cons: "Tiny old plane, props blocked my window view, no entertainment system."

Pros: "Food was nice and plenty. Great movie selection. Very polite crew."
Cons: "The seat was a bit uncomfortable and not big enough."

Pros: "The staff of the flight were very friendly and attentive. They were great!"

Cons: "I'm tired of Delta making it IMPOSSIBLE to experience benefits of my loyalty. I flew literally AROUND the world in the past 6 months and it STILL doesn't qualify me for anything more than Silver elite? Seriously? When you use a voucher because of their error to lower your ticket price, but still pay cash for it, why does that then automatically exclude you from upgrades? Poor customer loyalty, in fact, non-existent these days."

Pros: "Delayed and told die to Air Traffic Cintrol with ninproxtove means to resolve our delay. Poor customer sefvie at JFK...indifferent and lied to us."

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: "From the Ground crew to the Flight crew, you can feel the genuine care and thoughtfulness of everyone! They even remember you, if you fly often enough, and let you know how much they appreciate your business."

Pros: "Very professional and caring."

Pros: "plane had individual movies for free with each seat!"

Cons: "Flight was repeatedly delayed. Ended up being over 3 hours late to depart due to weather. Another delay due to mechanical problems."

Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "nice snack"

Cons: "We did not board at the scheduled time, although I believe we arrived on time. The crew was demeaning and singled out individuals who were causing the aircraft to not move. It was in a very pretentious manner, not like southwest personnel who have similar antics but with a playful tone. The plane is a small one where bags don't fit overhead and many head bumps occur. We arrived fine which mean the flight was successful but it was not very enjoyable."

Pros: "Left on time, arrived early. Great cabin service, attentive and polite. Comfort Plus seats are worth the extra few bucks."
Cons: "Nothing. Low rating for entertainment only because there really wasn't any, but I wouldn't have used it anyway, so no big deal."

Pros: "All went as planned and expected. No thrill- like taking a Greyhound bus in the old days...gets you where you are going but without much pizzazz New seats and quite clean, but the new seats were very hard and uncomfortable after an hour."
Cons: "Somewhat claustrophobic and always wish the drop down tray table behind could be disconnected from my seat. When the passenger behind uses the tray as a set of bongo drums to keep beat with his headphones it is a pretty miserable trip."

Pros: "Games and videos were good. Food was ok."
Cons: "Not enough leg room. Need at least another 2 inches."

Cons: "I'm not sure how you lose a bag on a direct flight from Atlanta to Denver, but Delta found a way to do it. They didn't even put my bag on the plane and had to send it with the next one coming. To their credit, they did drive it out to my house when it got here."

Pros: "They were smiling and very welcoming"

Pros: "Crew were good"
Cons: "Delayed departure resulting in missed connection. 2 hours in lineup and ‘service’ from Lufthansa. Rebooked through Zürich with overnight there - had to find own hotel as they said all the ones on their list were booked. Will not be using this airline for a long time ( they lost our luggage for 4 da"

Pros: "It didn't crash."
Cons: "Food no screaming babies . Comfy seats and armrests,"

Cons: "The workers at Lufthansa can learn to communicate with one another so that people don’t miss their flights. First flight stayed on the runway for an hour with no explanation for the delay. This caused us to miss our connecting flight, which clearly could have been avoided. Pathetic professionalism."

Pros: "Food was good (not pasta!), crew was very accommodating"
Cons: "Flight was delayed (again!). There was no desert with the food."

Pros: "Crews was excellent, always refilling water which I can appreciate so much. Keep it up! Loved the United pilot at John Wayne who came out just to say hi, let us know we were in good hands."
Cons: "Had to wait in tarmac forever from Frankfurt to Florence"

Pros: "Nice plane, about the best in-seat entertainment options I've ever encountered."

Pros: "Plane was comfortable, ample, with plenty of room, departed and arrived sharp in time"
Cons: "Boarding process was a mess, no one respected nor enforced priority boarding, they call for business and preferred access boarding and everyone rushed, and the airline agents just started to accept all people"

Pros: "One flight attendant in particular was outstanding, Eva. Because of her, I would definitely consider Lufthansa for our next trip to Europe!! She mot definitely went above and beyond in her service and professionalism."

Pros: "Best part was how Lufthansa took care of travellers whose connection time was short. They had ground crew waiting and who escorted us through customs, and then drove us to the gate. This is how passengers should be treated. ~ Excellent movie selection ~ Great flight attendants"

Pros: "Some how i ended up in the "small child zone", The crew was very kind and moved me to another aisle seal towards the front of the plane. Crew would come by with liquids quit often, The food was very good quality. huge selection of entertainment options."
Cons: "A very long wait for luggage, That may have been the fault of the airport."

Pros: "Excellent service, food and entertainment"

Pros: "Was not allowed on flight"
Cons: "When I missed the connection from the first leg of my flight and purchased the ticket from that leg to finish my itinerary, Lufthansa cancelled ALL of my return tickets. Both Lufthansa and my travel agency pointed the finger at the other and I had to purchase another $1000 ticket to get home. There was no cancellation emails or any notification. I didn’t know my tixkets were cancelled until I was trying to check in. Worst experience ever!!"

Cons: "Missed so there was none Spent night in Minic"

Pros: "All airplane was on time"

Pros: "Great costumer service, comfortable flight"

Pros: "Great service and flight crew"

Pros: "Roomy seats, excellent service!"
Cons: "Nothing I didn't like!"

Cons: "The staff was very unfriendly and they had inconsistent rules with carry on baggage."

Pros: "The crew were amazing!"
Cons: "I had to pay extra for "out of sequence" booking as I wasn't able to catch the flight out of Manchester to Athens. so i booked a different flight the next day to a different airline. Lufthansa canceled my booking as I didn't take my outbound flight, when they found the booking, they asked me to pay extra. Such a waste of money! Although, the crew on the plane were really good!"

Pros: "the woman who helped me at the boarding gate was great! Lounge was really nice!"

Pros: "The energetic crew who served with a smile"
Cons: "The tea was not strong and was served lukewarm and movies not up to standard.how about new blankets...and food only a choice between 2...chicken or pasta..why not beef or mutton?"

Cons: "Same as Abu e"

Pros: "Nothing no communication for delayed flight lost luggage. Just lines everywhere to fill out forms with only 2 employees worst experience ever"
Cons: "No communication. Flight delayed no answers. Just long line to be put on a waiting list"

Cons: "First flight mechanical issue so couldn't make it to any of my connecting flights and they had to reroute me, however they couldn't get me to Torino so they got me to Milan and I had to take a two hour bus and then the metro to get where I needed to be. And it took them over an hour to reroute my flight!"

Cons: "Flight delayed 1.5hrs after landing in Denver."

Pros: "The plane was clean. Some of the attendants were very kind and helpful about our situation (the plane left 35 minutes late from Athens and we were in danger of missing our next flight to the US). Food was pretty good. Small portions as usual."
Cons: "Pretty big delay before departure, ended up in very stressful conditions for the rest of the trip. It became pretty obvious that we were cutting very close to the boarding time for our next flight (arrival scheduled for 4:05 pm and our flight to Chicago barding on 4:20 pm). One of the flight attendants kindly offered us to move up to the front seats of the plane on the last 15 minutes of the flight (with our luggage) so that we can exit as soon as possible. We moved (per his suggestions) and we were treated rudely by the young lady attendant of the Business Class. We explained that we moved after the suggestion of their other flying attendant. She called her supervisor on us, who in return, rudely, arrogantly and loudly started to berate us on how we "dared" to move ourselves to the Business class. After explaining the whole story again and showing her the tickets, she allowed us to stay to those seats for the last 10 minutes of the flight. We asked if an airport cart could be called to transfer us to the next gate, and they said no. We asked for information on the gate for Chicago and they did not provide one. Unfortunately, the plane landed very far from the gates. We had to enter the airport bus, which traveled for about 15 minutes before we got on a gate. There, we faced about 35 minutes of passport procedures and waiting lines. At that point, 5 minutes before our plane for Chicago was supposed to take off, we asked the passport pre-check officer what we should do (we assumed we would be missing the plane at that point) and he told us very rudely "When you REALLY miss your plane, then come back and ask me"!!!!!!!!! Then we passed through passport check and we were told to run to our gate (which by that time was no longer showing on the computer screen, and we knew about the changed number, ONLY because KAYAK sent the update to us-THANK YOU!!!). We ran for about 12 minutes. We arrived at our gate late by about 25 minutes after our flight was supposed to leave. There we were asked why we were running and when we told the guy who screened our boarding passes he responded "Well, running is good for your health..."!!!!! At that point I would have liked to give him a piece of my mind...We were told by the same guy that due to airport security issues, Frankfurt airport had so many delays in the last couple of weeks that planes know to wait for the late passengers. Couldn't someone have told us that before? We have NEVER been treated so poorly by an airline and we will NOT fly with them again. The LUFTHANSA customer service was terrible. We have not encountered such arrogance and lack of information for many years...Shame on them! AND we were not the only Americans running. There were families with little children and older people, etc etc, just because the Lufthansa attendants and ground crew did not feel like giving us the information we needed!!!"

Cons: "Can they turn the heat up. So cold!"

Pros: "The service was friendly and helpful. The ride was smooth, the plane was clean and comfortable and everything was in top notch shape."
Cons: "Nothing"

Pros: "The crew were very professional and accomodating."
Cons: "Couldn't check in on line"

Pros: "Nonstop flight."
Cons: "The seats are the most uncomfortable I've ever sat in. The food from Frankfurt to Denver was subpar. The first 2 hours were very bumpy and unusual for that part of an Europe to USA crossing. The spacing of the middle seats with the support struts having to straddle for 13 hours is too much. I could go on, but you really need to rethink the design and customer service on your long haul flights."

Pros: "Hope to make today's flight home! Time will tell."

Cons: "It was a great second experience"

Pros: "Entertainment had great variety, flight progress software showed great detail of surroundings and progress. 4 bathrooms provided for our area allowed good availability. Hot towels, metal silverware nice, and not available on competing airlines. Overhead compartments were roomy."
Cons: "Legroom marginal and seat ahead reclines too far, takes away all usable space for reading, etc."

Pros: "The staff was so prompt and friendly, the food was the best airplane food I've ever had, and the entertainment options were great!"
Cons: "cramped leg space"

Cons: "The crew was ignorant and I did not recieve a meal after asking numerous times."

Pros: "The crew was focused on our needs but was not able to help in my situation."
Cons: "The flight was very crowded and I had a HUGE individual sitting next to me in that he actually overflowed into my seat. Due to the fullness of the plane it was imposable for me to move and very uncomfortable. For an individual this size there should be a requirement for them to have a business class seat or to purchase 2 seats. The food was very disappointing overall."

Pros: "You'r aamazing, great deals! Thank you!"

Pros: "thanks to friendly and attentive staff long flight went unnoticed"

Pros: "Great crew, very attentive. Excellent food and beverages! You don't get off of Lufthansa flight hungry! Good choice of entertainment. Lufthansa really knows how to take care of its customers on long-haul flights!"
Cons: "Online check-in is very difficult. told me that my request couldn't be completed, then when I got to the airport, they said "Oh, I see that you have already checked-in!""

Pros: "Lufthansa was very professional, in terms of their crews, procedures, and condition of the aircraft."
Cons: "I bought an aisle seat in the center section near the back of the plane because the diagram of the plane's seating area showed an empty space in front of the row I picked. On the actual plane, it was simply a normal row, with no extra space in front of it. Going to register complaint with Lufthansa and seek refund of seat cost."

Pros: "Flight was on time Flight crew was exceptional Entertainment screens was a great way to pass the time Food was good Baggage made it with no issues"

Pros: "The wide selection of movies, tv shows, etc that were available to us."

Pros: "On time departure and arrival."
Cons: "Boarding was by shuttle bus on a rainy cold morning. Food was terrible, omelet that didn't have any taste and was served almost cold."

Pros: "Jumbo plane was comfortable."
Cons: "The long lines to renter back to the state at imigration"

Pros: "I liked the notifications I would get about fight status. Very friendly people at counter."

Pros: "Excellent service from the Aegean airlines crew. Great flight and excellent in flight service by very experienced staff."

Pros: "Stewards were nice and the pilot updated us regularly about why we were still not going anywhere."
Cons: "Before a ten hour flight we sat for almost three hours on the Tarmac."

Cons: "servise @ Athens airport sucks!!!! never again."

Pros: "The crew was outstanding and personable and friendly!!! Greatly appreciated that on such a long flight."

Cons: "The airline lost my suitcase and deliver it only 72 hours later... They refused to give me proper compensation for items that were broken..."

Pros: "A flight was delayed due to weather conditions and we had to sit in the plane for almost an hour, BUT information sharing from the Capitan was sufficient and on-time. Very good job from pilots. Leg room in economy - I was positively surprised, very decent leg room! Thank you for providing it."
Cons: "I flew economy and all was good and appropriate to the level."

Pros: "Impressive service... amazing crew, very friendly and professional"

Pros: "Fast boarding"
Cons: "Slow in refuelling, got us delayed for 40-"

Pros: "Flight and the crew!"
Cons: "Staff at the airport pushing you to upgrade to first class but not making it clear only the first trip from Athens to Amsterdam which the first class uses same uncomfortable seats as the economy to pay extra 130 euros ridiculous airfrance stuff! I should have flown all the way to NYC first class!!!"

Cons: "Seats in economy section are very close together . There is not enough room for knees...especially for such a long trip."

Pros: "Great airline"

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: "The crew was pleasant"
Cons: "Baggage checkin & flight boarding was slow & disorganized."

Pros: "The crew was amazing, flight on schedule and good entertainment."
Cons: "Space is just reasonable on a long flight, even if there's seats more spacious that you could choose if you pay more."

Pros: "Food and service"
Cons: "Working wifi would be good. Better A/C. More comfortable seats"

Pros: "The flight was smooth, the service was friendly, and the food with plentiful."
Cons: "Too much activity in the cabin during the flight."

Pros: "Crew was amazing, seats were comfortable with enough leg space even without choosing extra space seats. It was my childhood dream come true to fly with KLM. It was really an exciting trip for me, just that it was short."
Cons: "Well, for me everything was on point. Those who have never travelled with KLM, I would encourage them to do so and I’m sure they will not regret."

Cons: "Larger meals."

Pros: "Smooth flight."
Cons: "Seat a little cramped."

Pros: "Nice flight ...was comfortable travel ...good food.Thanks"
Cons: "No such things"

Pros: "The flight to Gdansk took off and arrived on-time and the staff were professional."
Cons: "The flight to Amsterdam from Gdansk was late and I had to RUN to the connecting gate. 50 minutes is NOT ENOUGH time to go through passport control."

Pros: "Seats were comfortable and there was enough room for hand baggage. I slept during the flight so do not have opinion on entertainment."
Cons: "Not able to charge my digital devices. When serving beverages and food, the same flight attendant missed me a few times. That was annoying but other attendants were very nice."

Cons: "KLM staff in the Prague airport were some of the rudest humans I have ever met. So incredibly uncaring and outright mean."

Pros: "Nice to have a wrap for the snack."
Cons: "Would have preferred boarding by row - back of the flight first so would have been more organized."

Cons: "The cabin crew was racist. She told me to move back from an empty seat just because she wanted one of the guys ( from her country ) to set on it! Very rude and racist."

Pros: "Friendly attendants. Decent food, and frequent snacks and beverages."
Cons: "No charging ports for electronic devices."

Pros: "Great service"

Pros: "Nothing"
Cons: "Super delayed. Could have fixed the issue BEFORE we were sitting on tha plane for TWO hours"

Pros: "The food service was good and the flight attendants were friendly."
Cons: "The plane was very uncomfortable. The seats were small, you felt on top of the person next to you, and there was no leg room. I am a pretty small person- I can't image how uncomfortable all of the taller passengers must have been."

Cons: "Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again."

Pros: "Flight crew was pleasant and attentive. Seats were comfortable for economy as well. We were allowed to check in extra baggage for free at check in which really helped since we would be catching a connecting flight in Amsterdam"

Cons: "That I was forced to check my baggage. I never received a chain ticket for my luggage. The flight has a 32 hour layover and KLM lost my luggage and it was not found until a week after my arrival back home. I still have not received my bag at this time. The boarding crew was manually tracking who boarded and who didn't. It was a cluster."

Pros: "It was so easy to board and I had no inconvenience. It took 4 minutes from when I said goodbye to my family till when I was at the front of the gate."
Cons: "Nothing! It was all great!"

Pros: "Everything - Checkin, crew, food, entertainment"
Cons: "Nothing"

Pros: "Jet airways flight till mumbai"
Cons: "Poor legspace in Klm flight till Amsterdam"

Cons: "Why do the crew have to slam the overhead and catering compartments to get them to shut?"

Pros: "Professional, friendly service. Punctual, safe flight. Comfortable, spotless airplane."
Cons: "What is there not to like about KLM? I cannot find anything."

Pros: "."

Pros: "Same as above"

Pros: "Good and plenty of food available."
Cons: "No power to charge phones, laptops, etc and no WiFi available. For such a long trip (10 hours) below industry standard."

Pros: "We love the flight all the way"

Pros: "Special treat for King's Day Friendly crew"
Cons: "15 min late boarding 30 min delay leaving the gate Very little leg room"

Cons: "seats on Jet air flight are very uncomfortable"

Pros: "everything"
Cons: "nothing"

Cons: "Since we had two extra bags (paid for in Chicago), they demanded to see my receipt before we could board in Amsterdam to Nairobi. We had trouble locating the receipt and we were not given an explanation as to why we needed it again. We were traveling with 5 kids including an infant and we were not allowed to board until we found the receipt. I thought surely they would have record that I had paid, but I guess not. We were the last to board and all very stressed out. The staff seemed not to care the least in our troubles."

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."

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: "Great food and movies."
Cons: "Might have lost my bag. I was told not to claim my bag and that it would meet me at my final destination. That did not happen. I even paid extra because of the over weight. When they charge you 100 extra euro you expect your bag to make it to its final destination."

Pros: "On time."
Cons: "Claiming that the plane was completely full (which it wasn't), They forced just about everyone to check there carry ons. When we got on board, there was plenty of overhead space. Supposedly, we should've have been allowed a carryon and a personal item."

Pros: "pleasant"
Cons: "Pleasant"

Pros: "Flights left on time, arrived ahead of time. Seats comfortable. Baggage arrived quickly. No charge for wine/beer, although I do not imbibe when flying long distance. Food ok for airline food."
Cons: "Unable to pick seats in advance,, were assigned seats that did not recline for 11 hour flight. One bathroom not functioning. Very limited movie choices for inflight entertainment. Seat belts much shorter than other airlines, so very confining, unable to loosen to relax in any position other than sitting straight in seat. In Rome had to check in & go through security at Terminal 5 then get bussed to Terminal 3. Only airport where we had to take out all electronics, including converter plugs, headphones, etc, place in a flimsy clear plastic bag ( that broke ) to go through security. Line to check bags pretty slow for number of passengers. Glad we had plenty of time."

Pros: "Reasonable seat space for economy. Good selection of movies. Food reasonably good. Crew very efficient."
Cons: "Boarding at Amsterdam was disorganized. All economy boarded together. No row number boarding (which was the process for the outbound flight from San Francisco). Lights in economy were not switched off or even dimmed during the flight making it difficult to sleep especially if you had a window seat."

Pros: "During my first flight from East Midlands England to Amsterdam I lost my baggage by another airlines and the KLM crew was very dedicated and supportive until they found it and check in for me... Many thanks and I wouldn't forget it."

Pros: "New plane, new seats, new entertainment system. All very goo to great. The dinner was above average in terms of taste but the breakfast was pretty ordinary."
Cons: "Breakfast food wasn't very good."
