Airline reviews

Pros: "Staff were very good . Business class very comfortable. I had low salt menu which was very comforting to be able to choose as salt not good for me."

Pros: "Excellent crew. Very good food. Comfortable seats."

Pros: "The crew was very good. Seat was comfortable."
Cons: "Running water in the bathroom."

Cons: "Qatar Airways could improve food selection for business class."

Pros: "No comments."
Cons: "No comments."

Cons: "Great"

Pros: "Every things was great ."

Pros: "The A330, despite being an old plane, had really good recline."
Cons: "The entertainment was very outdated."

Pros: "So many carriers have cut back on so many things, our flight on Qatar Airlines felt like a throwback to the days when flying was enjoyable. Everything about our flight was better than we have come to expect from most other airlines. To highlight one surprise - the in-flight meals were high quality."

Cons: "The visa check personnel were the most discourteous airline staff I have ever encountered."

Cons: "Seat comfort"

Cons: "Delay at landing"

Pros: "Great crew. Met every request and did a very professional, yet personal job."
Cons: "Overall meals were best I've had on flights. Did not care for last one but probably just a personal taste."

Pros: "courteous service and a clean modern airplane"
Cons: "The sound system was inadequate on the TV and the headsets were uncomfortable. The queue at the check-in needs to be better controlled, it was a bit chaotic."

Pros: "Amazing airlines. Lots of food and snacks. Because of a long layover they even got us a hotel room for free!"
Cons: "Very strict luggage rules, even flying international we were only allowed a handbag on board, not our carryon"

Pros: "Confort"
Cons: "Same as above."

Pros: "Good movie selection, very friendly crew"

Pros: "all nice"
Cons: "nothing but avoid bread"

Cons: "Even though we landed in Doha before our connection left ( barely-20 min)on Qatar airways, they would not hold the connecting flight for the 7 of us who were connecting. This was extremely disappointing as we then lost a full 8 hours of our first day arrival. If they schedule you for a 45 minute connecting flight, I suggest you book a later one. Our flight from NYC left on time but was 20 min late landing. Their only compensation to us all was use of the airport lounge in Doha ( quite nice with free food wine and showers, but would rather have had the extra day in Bali."

Cons: "I didn't like that my original return flight selection was changed one month after confirming. The new flight details which were automatically chosen for me had me coming back home a full day later. This forced me to have to select a new return flight with an 8 hour layover."

Pros: "Entertainment was good. Food was good, I got the Hindu vegetarian. Also service from Nagpur to Doha is very convenient."
Cons: "It was mostly a good experience."

Pros: "Flight crew was quick to provide food and drinks but quality of the food was not as good as Emirates."
Cons: "-carry-on did not fit on center overhead compartment unless I put it side ways, which then takes up space for other passengers. Same carry-on suitcase fit nicely on Emirates airplanes. Basically, carry-on overhead compartments have been made smaller on purpose or by engineering error, and this makes me not want to fly Qatar airlines again. Less food options. I went to the Gally and they only had kitkat bars for food. Emirates offer fruit, sandwiches, and many choices at ALL TIMES of the flight for economy class."

Pros: "Heavenly for an airplane ride!"

Pros: "The crew service"
Cons: "The cost of internet access"

Pros: "Friendliness of staff. Cleanliness"

Pros: "i do like service in plane and at the counter no problem with baggage.all ok.thank for good service.sincerly vladimir hodan"

Pros: "I truly love this Airlines. The crew is always friendly. The food is always above par for airplane food"
Cons: "N/A"

Pros: "Crew welcomes"
Cons: "Bad takeoff and landing"

Cons: "my flight from Boston to Doha was deleyed and Qatar Airways have no arrangements for the passengers at the airport, I spent more then 15 hours in the transit on those chairs, there was no help provided by the airline"

Pros: "I liked everything from A to Z! the aircraft was spacious and new. The staff were very friendly and cooperative and attentive. the seat was comfortable and entertainment system was great!"

Cons: "For 14 hours flight, we were given 1 meal and 1 snack ; that seems too little for a long flight. They didn't have whiskey, only beer and wine...really... I asked the flight attendant to put my cabin luggage in the space above the seats, because I am old and could not do it myself, and he first frowned and asked why....ridiculous"

Cons: "USD 20 wi fi and you only get 200 MB seems a bit antiquated"

Pros: "Flight was on time and departed as scheduled. Flight was comfortable and seats were decent. Would have liked a little bigger seats and more legroom in the economy seats"
Cons: "Food was not up to par and seats could have been a bit bigger for the economy bracket."

Pros: "This airline cares about service and customer care. My son was not feeling well and they attended to him and made sure he was feeling good. They even suggested taking him to the clinic at the airport, yes the airport has a medical crew on site to treat passengers."
Cons: "Seats are crammed like US airlines. Not much leg room. But still far better than flying any US airline."

Pros: "attentive crew food was good"
Cons: "old entertainment options little space to move about"

Pros: "It was a direct flight with good food and movies to choose from"
Cons: "Small cramped seats in economy"

Cons: "Seats were not very comfortable for economy class for a journey as long as these ."

Pros: "After hearing our complaint, the Transfer desk staff was friendly and helpful and solved the situation in our favour. We"
Cons: "Once we landed in Doha to board omthe connecting flight, ground staff was waiting right outside the hate to let us know that our flight was overbooked. We were then informed that we were put on the following flight arriving after midnight at our destination. Our compensation was going to be 250 USD and a free entry to the lounge. What a way to start our holidays."

Cons: "I was charged a insanly high fee for my luggage that was almost twice the price of my original flight ticket purchase. the agent offered no resolution for the confusion in their web descriptions for baggage allowance. This must happen to customers frequently because the wording is not clear. i was very upset and due to this i will NOT fly this airline again. i was charged the price of a first call flight in total for economy service. NOT GOOD"

Pros: "It was excellent."
Cons: "It was excellent."

Pros: "I liked everything about the flight and the service was great!"

Pros: "Staff were polite and helpful. Flight was smooth and on time. Overall very good considering length of flight and difficulty of accommodating such a large crowd for such a long time."
Cons: "Meal service was very disappointing. 16 hour flight with one meal at the beginning, one meal at end, and a small, rather unappetizing hot pocket like sandwich in between? And snack offerings were ice cream, potato chips, candy bars and a few apples (ran out of apples). Need more healthy options. There needs to be a more full meal/snack offering around the half way mark if you are going to keep people from grumbling."

Pros: "Comfort, entertainment, amenities"
Cons: "You have to improve the food service. The food tasted horrible. You have to circulate the beverage cart more often."

Pros: "***You're asking me about a flight that hasn't happened yet. I'm rating my flight FROM LOS ANGELES TO DOHA, 10/23/2016, here: Flight attendants were very good, helpful, gracious. For a long flight the restrooms stayed clean."
Cons: "The food was over cooked, and lacked freshness. I had to have the same meal twice because they ran out of the omelettes. Next time I will try Emirates."

Pros: "Boarding on time. Crew was very nice except food option."
Cons: "My wife didn't get veg food she is looking for. We asked crew and they said they don't have."

Pros: "The food and seats were very comfy."

Pros: "Everything"

Pros: "Crew polite and efficient."
Cons: "Boarding process non-existent. Huge queue of 80+ people. Seats average comfort. Food bland. No entertainment other than on the overhead displays. Will avoid flying with this type of plane / flight."

Cons: "My parents came from India to U.S. They had wheelchair, but they didn't get it and they have knee problem they don't know English too. So I had very bad experience with Qatar."

Pros: "Crew"
Cons: "Earlier travel and respect of initial timing. If they also afforded a place to rest for the long lay over in turkey."

Pros: "Crew amazing, seats were comfortable."

Cons: "Room temperature control should be better."

Pros: "TK Lounge in Istanbul"
Cons: "Business Class boarding process is not well setup. I expect that If you are paying significantly more for a business class, you would have priority boarding at least ... this didn't happen. We were asked to be there at the gate 1 hr before the flight of which 40 mins were spent just waiting in a room packed with people."

Cons: "I checked in 4 hours prior to departure. While in the international zone in Casablanca Airport my cellphone switched time-zone. As a result I arrived "punctual" at the gate exactly 1 h too late, the flight left without me. Neither Turkish Airlines nor Royal Air Maroc (operating this flight) attempted to contact me via my cell phone. Disappointing."

Pros: "Friendly crew, boarding on time, leaving and arriving on time, well maintained planes, clean."
Cons: "Seats on this flight were even smaller than the previous. It almost feels that these seats were designed for little kids."

Cons: "Boarding was delaeyd 5 hour's ,Very very bag experience, the trailer baby and car seat i waited more than an hour, together with more people, were not found"

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."

Cons: "Had to stay overnight in the lounge zone. Hotel inside the airport wasn’t available. Outside you have to spend sometime at the multiple lines, buy visa, get the voucher, take the shuttle bus... By the time you done with that, it’s time to come back. Didn’t expect that for the business class ticket holders."

Pros: "Food and service is excellent. Istanbul lounge is great."
Cons: "Delayed in both directions. Happens. But zero announcements. Zero. Staff didn't know what was going on. Complete chaos."

Pros: "On the plus side, the food, service, entertainment, and comfort on Turkish are the best of any Economy class overseas flights. For that reason, they are my top pick."
Cons: "I can't understand why I was booked with an impossibly tight connection. It's a huge airport, with multiple security checkpoints with long lines. I had an hour between flights, and the first flight landed just five minutes late. The gate for the second flight had already closed by the time I cleared the first security checkpoint. It would have been completely impossible to make it to the gate on time. Turkish put me up in a hotel, etc., for the night, and there were dozens of people in similar situations. But the airline shouldn't offer connections that are totally impossible."

Cons: "because your flight from Sarajevo to Istanbul was delayed we missed the connection to the SFO flight and had to stay another 24 hours in Turkey + pay $60 for visas......this was a connection that you had scheduled!"

Pros: "The benefits of being United Gold status is a real plus at the lounges and in the boarding process."
Cons: "The 12.5 hour flight is too long for my aging body!! Either bulkhead or business is needed for flights that long"

Cons: "Long flight"

Pros: "Food and staff were good."
Cons: "The seats were tight when the person in front leaned all the way back. His or her head was practically in my lap forcing me to lean back, to the annoyance of the person behind me. All was fine after the meal when everyone leaned back."

Pros: "The food and the crew were great!"
Cons: "The way they do boarding makes you feel like you are being loaded onto a cattle car."

Pros: "Great food, great plane, shortest flight."
Cons: "The restroom is too narrow on this plane, at least the one I tried. They ran out of one entree since everyone wanted chicken and not the fish. They should know this and make more chicken available and less fish. But I tasted both and both entrees were good. The "sour cherry juice" is great."

Pros: "Overall the experience was good with friendly staff."
Cons: "My luggages where ruined and there was heavy rain. The luggages where left out instead of being protected l, damaging clothing and the luggages themselves. Also they had us for over an hour in the airplane because of bad weather conditions instead of having us out!"

Pros: "Staff are welcome and supportive.at Istanbul Airport kindly re-opened the gate for late passengers due to unexpected delays of preceding Turkish Airlines flights. Otherwise, I must have missed the flight from Istanbul to Rome."
Cons: "Delayed departure for nearly 3 hours from Islamabad to Istanbul (TK711)."

Pros: "The water"
Cons: "There was a malfunction on the aircraft after the first taxi attempt. I understand that these things happen but there was zero communication from the captain or the crew. Because there was no power, the A/C was not operational and the cabin grew extremely hot. No water was distributed, and no attempt to communicate the situation with the passengers. The pilot power cycled the aircraft numerous times, which is normal to reset the various systems, but this made many passengers nervous. Finally the issue was resolved and we went on our merry way. In short, all crew-passenger issues could have been resolved with more communication and water. Go forth and sin not again."

Cons: "We were traveling with our 1 year old. On any other flight, we've been given seats with extra legroom and a bassinet when available. Turkish airlines put us crammed in a window and middle seat for a 9 hour flight. It was absolutely un-doable. Everyone around us realized this and tried to help as we asked the flight attendant to help us and she said that I should ask other people to move around not her. We had to go around the plane begging people who were sitting with a bassinet and no baby to trade seats with us. It was an absolutely horrible experience. It was the airline's mistake, and we were the ones forced to try to fix it. Yes, we got a bassinet eventually, but not before we saw how mean and selfish other passengers could be pretending not to hear us and ignoring us. And no help from the crew."

Pros: "Everything was very good"
Cons: "Everything"

Pros: "Food and comfort was great."
Cons: "Israel requires them to close bathrooms forvlast 30 minutes but there was no warning. So when tried to go 30 before landing had to wait until we landed."

Pros: "The food"
Cons: "Was late"

Pros: "The flight didn't take too long"
Cons: "The staff at the airport is really rude and just tries to push you off to another person. When you do finally talk to someone they will give you a short blunt answer and try to get rid of you. The WiFi is horrible and hardly works. There aren't any quiet places to sleep and many of the phone charging stations cost money."

Pros: "Gave us direct flight back to Singapore in premium economy seats."
Cons: "This is our second experience of flights being cancelled via Turkish Airlines. Very disappointing customer care when flights get cancelled. Staff totally unprepared and untrained for such situations. We waited around for 6 hours before finding out on our own, that the flight was cancelled. The notice was not shown on the board. In all waited around at the airport for more than 10 hours before we were finally carted off to a small hotel near by at 1230am in the morning. Very little to no information given throughout the whole process, stranded with parched throats, no luggage, clean clothes or toothbrush."

Pros: "The food was pretty good"
Cons: "The seats were too close so you could hardly move when the seat in front reclined. They didn't clean the bathroom during an entire 13 hour flight and it needed it."

Pros: "I just like Turkish airlines"

Cons: "Everything was pretty good."

Cons: "I made it to the flight gate 15 minutes before the plane took off. The crew could not re-open the doors to let me in. I was late; this is understandable. However, after that, this was the worst customer service experience I have ever had. WHY WERE THE REST OF MY FLIGHTS CANCELLED? I paid for those, and I should have been allowed to be on those flights. WORST FLIGHT EXPERIENCE OF MY LIFE."

Pros: "Boarding experience was chaotic however that wasn't due to Turkish Airlines."

Pros: "Crew service, as it was a big airobus, half plenty it was very comfortable to be there"
Cons: "lateness at least 40 minutes, while nobody from staff I was worrying about corresponding flight,"

Pros: "The service is very good. The plane departed on time everything was good"

Pros: "Missed my flight because the airport changed gates and didn't announce it. Was told I could pay a penalty o in excess of $450 to be placed on another flight, meanwhile same flights from Istanbul to Amsterdam were going for $213. I will avoid Turkish Airlines at all costs. Customer service is terrible. The most unprofessional, rude, ignorant, and disrespectful staff represent Turkish Airlines at IST. Furthermore, an email complaint has been ignored."

Pros: "Cleanliness, wonderful crew,"
Cons: "The TV on my seat was not working"

Pros: "Great food; plenty of room to stretch out (we flew business class)."
Cons: "The service on the flight from Houston to Turkey was much better than it was from Turkey to Houston. For one thing, the flight attendant never made up our beds on the way back to Houston. For another, the sound did not work at my seat, so I was unable to use any of the entertainment. The flight attendant kept trying to give me different headphones...it wasn't the headphones that were the problem!! He never really addressed the issue or coordinated a possible seat change (even though there were empty seats in business class)."

Pros: "The Turkish airline staff was great and very helpful"
Cons: "Itinerary on the way to Amsterdam was not correct and made me miss my first connection No option to pick vegetarian food ."

Pros: "Good service"
Cons: "They need better movies and music"

Pros: "Good food, good entertainment options - movies, tv shows, games, newspapers, and some electronic games."
Cons: "Our flight backtracked over Europe - I think bcs all flights go through Istanbul - so our flights were longer than necessary even though cheaper... worth doing once bcs Istanbul looks pretty cool."

Pros: "The entertainment and food were excellent."

Pros: "Nothing"
Cons: "Check in late, rude staff, bad food"

Pros: "I liked the friendliness of the ticket person and all the flight attendants on both flights. The cabin was clean, the climate was not too hot or cold. The pilots were very good at their jobs. The food was good."
Cons: "Did not like boarding the plane on the Tarmac."

Pros: "It was a 55 min flight and they actual fed us with great food and drinks, and the plane had impersonal touch screans , witch is unheard of on such a short flight."
Cons: "Nothing"

Pros: "It was nice and easy trip to USA and back home to Moldova. Crew was attentive and helpful. Food was good and plenty to drink."
Cons: "It was red eye, and the light in the cabin did not turn off for a long time."

Pros: "Good entertainment, USB charging for phone"
Cons: "Bad seats, not very comfortable."

Pros: "Movie choices plentiful"
Cons: "Flight was delayed for almost an hour while passengers were on board the airplane."

Cons: "They ran out of the chicken dish by the time they got back to me. And my seat didn't recline."

Pros: "Food and comfort for the price paid"
Cons: "Need more assistance during boarding in Dhaka/ DAC"

Pros: "Great screen and movie selection."
Cons: "Zero leg room. Worst I've ever been on for a long haul flight."

Pros: "I had a great flight from Istanbul to Berlin. I enjoyed the Turkish delight they passed out after reaching altitude. We were also provided an enjoyable chicken dinner. I liked the way the captain came over the audio system and gave us information about what part of Europe we were flying over, it was interesting for me. The take off and landings on both Turkish airlines flights that day were very smooth and on time."

Cons: "A quick drink service would have been nice, it was provided on the same flight going the opposite direction"

Cons: "100% as always.. delta has never disappointed! Keep up the good work guys"

Pros: "The crews were super accommodating and my seat was so comfortable I actually feel asleep which is something I have never done on a plane before."
Cons: "Load the plane from back to front. It makes sense as people leave the plane from front to back"

Pros: "Good"

Pros: "Availability of WiFi, a charging port and media options puts Delta a step (or two) ahead of their competitors. The professionalism of the crew, as well as the complimentary food/beverage options are also excellent."
Cons: "Not the airlines fault, but my 6’4” frame doesn’t fit very well in a middle main cabin seat."

Pros: "In flight entertainment"
Cons: "Food provided, other than snacks, would be a plus"

Pros: "We arrived eventually."
Cons: "Flight delayed three hours. Payed extra for an earlier flight. Very disappointing."

Cons: "Delayed 4 hours"

Cons: "We sat for an hour on the tarmac with the plane at about 80-85 degrees and everyone sweating. Once we took off the flight attendants kept turning the cabin lights on and off and serving dinner (on an overnight flight is that really necessary?!) and waking us up. Also plane was old and uncomfortable."

Pros: "Crew."
Cons: "Getting to Venice on time. Our late arrival cost me a 90 euro shutle."

Pros: "Comfort + was nice."
Cons: "Had a middle seat between two other men. I was given my seat by the gate. It would have been nice if they placed my more strategically. That might be asking too much but seems reasonable."

Pros: "Nothing spectacular."
Cons: "The headrests won’t stay up. And it’s hot."

Cons: "Have rhe right to carry at least one luggage per person at no cost. Besides carry on and personal item. Tickets prices and luggage costs are extremely expensive."

Cons: "Seats are so small. Flight was delayed."

Pros: "Staff from Check in to aircraft very pleasant. Snack choice in Coach impressive."

Cons: "Denver airport is far too large for there to be such a small security check therefore it took forever and I missed the flight. Delta tried to charge me $1000 for another ticket to Albany and I decided to fly with another airline for half the price instead"

Pros: "Nothing"
Cons: "I bought a ticket thinking i bought it through kayak but I actually bought a ticket through a third party in India. Where no one spoke good English. I called the agency to find out if I needed a Visa for my visit to Australia and the told me no. So when I showed up to the airport I didn’t have the right documents and I MISSED MY FLIGHT. Also the wouldn’t just change my flight and charge me the change flight fee. They cancelled my flight entirely and made me buy a whole new ticket!!! Worst flight experience I’ve ever had and this is not my first time flying to Australia or out of country."

Cons: "Had to wait for the crew from another flight before boarding p"

Cons: "The seats were in bad condition, I was surprised as Delta usually has well cared for interior and exterior airplanes."

Pros: "The flight attendants were all helpful and pleasant. The seats were comfortable. We were provided with plenty of liquids."
Cons: "The landing was pretty tough and we took off almost a half hour late."

Pros: "Check in Denver super helpful Gate staff hustled to turn around flight Flight crew excellent"
Cons: "Flight delayed, almost missed international connections"

Pros: "Boarding, friendliness of staff"

Pros: "Everything was easy and smooth."

Pros: "Anything from free WiFi, entertainment, leg room, commentary drinks and snacks. Great service!"

Pros: "The staff was polite and snacks were good (healthy options)."
Cons: "Nothing was terrible, but due to the short flights I assume they don’t worry about having planes with entertainment available."

Pros: "Short flight"
Cons: "In SLC they boarded by row numbers and not zones. Weird..."

Pros: "Good flight crew"
Cons: "Delayed due to mechanical issues. For 3 hours. No offers for free drink or wi fi. When we finally land we were on the runway for half hour."

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Pros: "Nothing!"
Cons: "Everything"

Pros: "Delta is great"

Cons: "Poor Delta DEN counter agent experience. Name on ticket didnt match Delta profile name nor TSA [rofile name. Delta counter agent would do nothing, except blame TSA. Would not check ticket name vs profile name. Happened two consecutive flights. Flight tomorrow morning has no TSA Pre clearance on boarding pass. This will be three consecutive flights. Also seated me next to a person who needed 2 seats to himself. Please never seat me next to a passenger who cannot fit in their own seat. I am switching to SWA."

Pros: "On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you."
Cons: "On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra."

Pros: "Crew was nice."
Cons: "The Entertainment sucked. Again I was sitting in comfort class which in theory should buy you more comfort and better entertainment. There was a ton of movies from the 90s and the same movie selection from about 6 months ago when I traveled with them. Also, what is going on, with having to use your own cell phone to watch movies on the plane? Whatever happened to the screens in the backseat of the front seat? I ended up with neck pain from trying to watch a movie on my phone. Delta has become very cheap. It is going into some serious decline."

Pros: "Entertainment system is awesome and similar to what I usually see only on international flights."

Pros: "Most comfortable flight I have taken in some time. Spacious seat, power, good entertaiment, attentive flight crew. On time. Not usually a Delta flier, but times and destination made Delta the choice. Turns out a great choice."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Crew was the best!"
Cons: "I really dislike the snack boxes. Snacks need to be more like a small sandwich or grapes, cheese and nuts. Not all that packaged stuff."

Pros: "Boarding super excellent! Also: Best landing I've ever experienced! Props to the pilot!!"

Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Pros: "So many movies to watch. Keep it up!"
Cons: "The food was too sweet and salty."

Pros: "Excellent crew and comfortable flight"

Pros: "Friendly Staff"
Cons: "Check in was very hectic due to limited staff and getting bumped by the red carpet flyers. Boarding is always a little congested due to the lines. Better snacks please!!"

Pros: "We purchased economy tickets in Delta. With these tickets you don't know where you are sitting until you get to the airport. Well, we lucked out and got the Plus seats! We got free alcoholic drinks, and big plush seats! We left right on time and got there early! Overall a great experience!"
Cons: "Nothing."

Pros: "Great,I loved it!"

Pros: "The moviea"
Cons: "The time of night"

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Cons: "More comfortable seating."

Pros: "The crew was fun, informed, and very helpful."
Cons: "The seat, the entertainment, the headphone jack, the food."

Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."

Pros: "Seat was comfortable, food was good."
Cons: "The woman seated next to me was the mother of one of the flight attendants. She had terrible body odor that nearly brought me to vomiting—and this was a 10 hour flight. She was also brought all kinds of amenities from the attendants from the 1st class cabin—not really appropriate."

Pros: "I was happy with everything stewardess where very friendly everything went smoth"

Pros: "Great"
Cons: "No problems"

Pros: "Most uncomfortable flight in years. No space. Hard seats, horrible food, had to beg for water. Little service, and not friendly. Overall a horrible flight. At least we made there on time"

Cons: "My luggage did not arrive on the flight from Frankfort to Athens. The Lost Luggage staff was very helpful, but the process took a long, long time. Then when my luggage arrived the next morning, no one was staffing the Gold kiosk, so it took another hour and a half to get my luggage. (We had received an email saying that the luggage would be available at 7:30; no one was there to provide it to us)"

Pros: "The crew and amenities are excellent!"

Pros: "Great service!"
Cons: "Breakfast and movie selection could have been better"

Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."

Pros: "Slept like a baby with no interruptions."

Pros: "1 hor 30 minutes instead of 2 hours 15"
Cons: "Worst food ever, and zero entertainment"

Cons: "Wheelchair assistance did not arrive at gate."

Cons: "Limited choice of types of meal - no vegetarian option."

Pros: "The crew was very friendly and polite. The airplane was clean. The boarding was quick and easy. The entertainment was varied and enjoyable."
Cons: "It wasn't an issue on my flight since there were empty seats in my row, but I don't enjoy the spacing provided for personal items on the floor under the seat in front you. For four seats there are three sections; so, you can hope that someone doesn't need any space or else you have to decide how to awkwardly split it up."

Pros: "very professional cabin crew"
Cons: "The overhead bins are way too small, and they ran out of the vegetarian dinner option. There are no longer air controls for each seat, and the plane was quite cold."

Pros: "See above"
Cons: "See above"

Pros: "Flight attendants we good"
Cons: "Business class seats were just regular seats without a 3rd person. Legroom bad and seats narrow. Not good value b"

Pros: "The best in-flight service I have ever had on the Lufthansa flight from Denver to Munic!"

Cons: "We were charged a rebooking fee by Lufthansa when customs searched luggage causing us to miss connecting flight"

Pros: "Crew worked very hard to accommodate us."
Cons: "Was seated in a section with many noisy infants. I could not sleep or even hear the entertainment system sometimes. Not the airline's fault. People should know better than to travel with infants. I felt sorry for the crew."

Pros: "Great crew service"

Pros: "the crew are exellent"

Cons: "Vegetarian meal choice not offered"

Cons: "A man next to me took a picture of me when he thought I was asleep."

Pros: "Everything"

Cons: "Couldn't sleep because of seating."

Cons: "Unhelpful and now luggage has been lost going on 3 days in same clothes"

Pros: "Nice crew"
Cons: "Lack of leg room!!! After my bicycle box was inspected they failed to secure my bike the way I had it in the box. Bike was flipping around in box. Bent rear brake calipers. Bent brake hoods. Rear skewers were uncoupled. No way to treat a $10,000 bike! Very upset!"

Pros: "Pleasant crew."
Cons: "Annoying kids in seats behind us :( Not enough leg room for someone over 6 feet tall."

Pros: "It departed and arrived on time. The boarding process was very efficient thanks to Frankfurt's automated ticked checking gates."
Cons: "No in flight entertainment."

Cons: "They boarded everybody at once through a jetbridge made of glad. Very hot in there. You were stopped in a crowded jet bridge in 90 degrees for 25 minutes because they board everybody at once and it took time to get passengers into their seat."

Pros: "Great atmosphere, crew was excellent!"
Cons: "I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone."

Pros: "Crew good and seat OK but not exceptional for business class"
Cons: "Food was average - main course could have been better. Range of movies ok but not great"

Pros: "The crew tried to be helpful but were equally frustrated with the ground crew."
Cons: "Follow your own policies. Allow people to board (economy plus) with their hand luggage who have followed all the rules and chosen a seat in the front of the plane. My daughter and my KLM approved baggage were taken by the boarding crew while allowing other passengers to go with more than allowed"

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!!!"

Pros: "Great crew."
Cons: "Ran out of business class meal. Substituted a Econ class."

Cons: "Flight was delayed, had to run to my next connection flight."

Pros: "Great airline"

Cons: "The plane is so old..,"

Pros: "Reclinable seats."
Cons: "The food!! The lights could be dimmed as it was a night flight."

Cons: "I was seated next to the restroom, which is not a pleasant experience for an international flight."

Pros: "The crew was amazing, flight on schedule and good entertainment."

Pros: "Crew"
Cons: "N/a"

Pros: "Boarding was as expected, crew & food were ok. Nothing else positive to extract out of this flight."

Pros: "Nice flight, nice crew, and a nice experience."

Cons: "Actually the Welcome on board announcement. The part where they special welcome loyalty program members. I do not get that... I am an explorer holder my self, but really?? so other paying customers are not as welcome. This is leftovers from the older days.."

Pros: "Short flight with good communication."
Cons: "Nil to complain."

Pros: "Good information and helpfil boarding."

Pros: "was very quick"

Pros: "Cabin crew very pleasant"
Cons: "Lost our bags, little sympathy from staff"

Pros: "I was pleasantly surprised they had a snack service on such a short flight. The flight attendants were very friendly"
Cons: "Amsterdam customs is the most disorganized I have ever seen. With the number of tourists entering the country you would think they would have done something about it. There were only 2 customs agents!! One for all passports and 1 for all passports. We were in the customs hall longer than we were in flight!"

Pros: "Of the multiple international airlines I recently flew with, I would have to say KLM was by far the best. Relaxing atmosphere, comfortable seating, great in-flight entertainment, although I have the go-go in-flight data/entertainment plan with t-mobile (highly recommended), the flight included a decent selection of movies, television programs, etc. The food far exceeded typical "airline quality," even for an international flight - and included a fabulous little snack box with locally sourced gourmet and specialty items such as chocolate from Belgium, fine cheeses from France, and crackers from England. Drinks = gratis, and crew was exceptionally attentive and went out of their way to make flight as pleasant as possible."
Cons: "Nothing."

Pros: "That we didn't crash"
Cons: "Being delayed and missing my connecting flight. No entertainment onboard (for hours and hours)."

Cons: "Pet was left behind at vacation destination as pet's reservation (made and confirmed through KLM) was not found at check in. Waiting for Customer Care to help get pet home and take responsibility for situation and getting no response. Very dissapointed, considering law suit."

Pros: "Staff superb. They even surprised us with an exit row and a gift for my partners birthday! Amazing. Samantha and Dennis also took time to come and personally wish him a happy birthday. A lovely touch. This airline runs like clockwork. They are just great. The sandwich and stoop waffle are nice too."
Cons: "There is a bus to the plane, so that takes a bit of extra time but they are very well organized."

Cons: "Flight delayed, had to take two more flights and was a four hour trip turned into a 12 hour, 4 countries trip"

Pros: "Flight attendants were friendly, but they only had limited resources to work with."
Cons: "Worst aircraft I have been on in years. No wifi or entertainment, no power outlets, only bad wine/beer for a 3+ hour flight is mediocre at best..."
