Pros: "Cozy big leather seats in Business Class, excellent breakfast and good service overall. Turkish Airlines continued to amaze me."
Cons: "Boarding by bus - not my favorite way of getting on a plane. Probably not the airlines's fault."

Cons: "Hate Anadolujet"

Pros: "The service"
Cons: "No entertainment. Late boarding."

Pros: "big screens, big movie selection, nice drink options, good menu"
Cons: "very small seats! hot on plane, with no optional vents, flight staff did not respond to multiple call button requests"

Pros: "Full meal and entertainment system even for a shorthaul flight."
Cons: "Tight leg room"

Cons: "Flight arrived 20 mins late. Luckily my connection is 12 hours later"

Pros: "On time. Really fast the check in. Nice crew. Confortable."

Pros: "Nothing in particular. It was kind of the worst flight ever. The crew seemed inexperienced to manage a passenger that looked to be disturbed emotionally and mentally."
Cons: "They kept moving the passenger to the back o free plane where I was sitting and I was so scared."

Cons: "THE bathroom esp at the back of the plan read very dirty. Went floors a d trash that was overflowing."

Pros: "The meals and in flight entertainment"
Cons: "The seating I needed more leg room"

Cons: "Older plane, uncomfortable seats, no individual entertainment systems. Long boarding without a lot of staff facilitating extra coat/overhead luggage storage because of winter, then we sat on tarmac for two hours because they missed their slot to take-off."

Pros: "Pilot did a smooth landing both the long flights."

Pros: "We received edit seats so we had more room which made the quick flight more comfortable."

Pros: "The seats were comfortable and the staff at the gate were nice."
Cons: "The crew for the first 9 hour flight was horrendous. They were quite unfriendly. I was in the dead middle of the plane, row 40, but we got our did last and there was no choice left. It was more like the crew forcing the food on us. The crew also was extremely bad about picking up after the meal. There were people walking around to throw away their food."

Pros: "The crew was excellent, the food good."
Cons: "The entertainment system, in three out of four long flights, did not work. In the one that "worked", the sound was terrible and this made the experience totally unsatisfactory. A major airline should avoid this."

Pros: "Finally loved that they had a vegan sandwich for me!"
Cons: "We were supposed to land with an hour and a half till my next flight. We landed and they were already boarding my next flight. It was very slow getting off the plane also. Took forever to pull up to be able to let us unboard."

Pros: "Everything"
Cons: "Nothing"

Pros: "The only thing that I liked was that I got to spend time in Turkey which is beautiful and had friendly people outside of the airport."
Cons: "Customer service sucked! Especially in Amman and Turkey . No one would help you when you need it in the airports and their desks are not open long enough to get the help that you need in Amman. Also, when you ask the information desk at the airport in Amman to call someone from Turkish Airlines they tell you that they can't because they won't come. I hope that this feedback would be used to make the airlines better because Turkey is truly a beautiful place."

Cons: "Headphones did not work"

Cons: "This 13 hours and 5 minutes flight was extremely hot. Regardless of how many times we've asked the flight attendants to make it cooler for us, nothing changed. By the time, we get off my shirt was soaking wet. Imagine flying for so long under these conditions. What an horrible customer service!"

Cons: "Policy"

Pros: "Service was nice, crew was very respectful and the gift were well within accomidation"
Cons: "Leaving the aircraft by stairs to the runway"

Cons: "The connecting flight from New York to Istanbul and Istanbul to Lagos Nigeria is bad time difference"

Pros: "Comfortable plane Good food Friendly service"

Pros: "We boarded on time, very well run, the food was great, great movie choice"
Cons: "The seats could use upgrading. I've flown aturkish quite a bit. Some planes have comfy seats, some are very still"

Pros: "The seats seemed further apart, thus more leg room for my long legs. I was lucky to have all 3 seats so I could lie down and get some much needed sleep. New seats seem flatter and more comfortable to lie upon if one is lucky. Crew very personable and helpful"
Cons: "I had FOUR TKA flights in my travels to and from Madagascar last month. Nearly EVERY seat I tried did NOT recline, nor could crew fix any! Most unpleasant to sit for 13 hrs. behind large man whose seat did reclione and mine could not. 2 yrs. ago I flew to Niger on TKA and I found the food better back then. Please keep the delicious Turkish food I fear a down grading for economical reasons. Don't do it."

Pros: "Add good airline to Atlanta to eu"

Pros: "Other than the late departure, everything else was excellent."
Cons: "Just the fact that we were some 40 minutes late, and this created panic among those passengers who had tight connections to Tehran, Tel-Aviv and Tbilisi. The rest was excellent!"

Cons: "Had to cancel due tp safety situation in Turkey (bombings, Dept of State warning). I had flight insurance but Kayak did not refund a dime."

Pros: "Loved the entertainment center and options. Loved the frequency of beverage service."
Cons: "Nothing. Everything was great!"

Pros: "Despite all other issues I got to Vienna on time."
Cons: "- there was a gate change less than half an hour before boarding, which was not announced via speaker or on the screen in the previous gate - therefore most people were still in the previous gate and only because one of the passengers realized and communicated the change everyone else became aware of it as well -> then everyone ran to the new gate, which did not have enough seating and where children were crying because they did not understand the hectic - On board - just before departure - two families got into an argument and yelled at each other and the crew. They were very loud and aggressive. - Usually I love the food Turkish Airlines serves, but this time I had dry and oily pasta and a very strange and too sweet chocolate mousse. I did not enjoy eating this and it did not taste fresh at all. - There was no entertainment."

Cons: "I could not find a way to ask for cancellation or reschedule"

Pros: "Still able to rest & crew very nice and helpful"

Pros: "Excellent service. Very good food. No comparison to any US airline. Internet over the entire Atlantic."
Cons: "In flight Internet interface is still a little bit clumsy to set up. Took me a little bit to get online. Once this is fixed, I would have a hard time to complain about anything."

Pros: "Nice new plane, decent food, friendly staff, incredible selection of movies. Appreciated the fact that the cabin wasn't freezing for once."
Cons: "Terrible, slow checkin process. Some people treated the checkin counter as their personal therapist, coffee house, I don't know what.., they held up the line for ages and staff was doing nothing to speed them up and move them along."

Pros: "I like the food, seats and customer service"

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

Cons: "Uncomfortable chairs for a three hour flight"

Cons: "Couldn't believe the flight attendant walked around with a tray of snacks and bananas. When I asked for the banana, she said, "Oh I'm sorry, those are for First Class only". Really?"

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!!!

Cons: "Cramped foot room"

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

Pros: "The cabin crew serving the main cabin were exceptional. They were efficient, kind and FUN. We were an hour late leaving and 2/3 of the plane was worried about tight connections. They handled it with grace giving each person their departing gate and asking everyone to let a gentleman off with a 10 minute connection. They made the flight memorably enjoyable."
Cons: "Being an hour late isn't ideal and I understand that it wasn't their fault (the plane was late arriving into Denver. Those things happen. They still goto people to Detroit in time to make connections--barely."

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

Pros: "Entertainment options"

Pros: "The flight attendants were so nice and accomadating. Even came by to refill our waters! I've never been on a flight with such friendly flight attendants!"

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Pros: "Was able to get on a flight after ours was cancelled. Delta was in scramble mode and their gate staff worked hard ot deal with a frustrated flying populaiton"

Pros: "The crew & service on our Denver to Munich flight were incredible. Courteous, professional & fun. A crew like this makes flying a pleasure."
Cons: "The seats in economy on the A-350 were a horror show. Couldn't have made them more uncomfortable if they tried. It seems with each new model Airbus puts out the seats regress to more medieval technology."

Pros: "best take off and landing I’ve ever experienced. 2 meals for an 8 hour flight and all the red wine I could drink!"

Pros: "Everything exceeded expectations. Lots of food, space, drinks, and excellent flight crew. Excellent video selection."

Cons: "Boarding process: just a lot of confusion. Inflight crew service poor: the was no time to have any brain reaction when they would pass by with coffee or anything...and when I asked for coffee the answer for a gentlemen of the crew was: coffee already passed by. Really!!?? Make sure that +$1200 are spent well. Rude or inattentive crew members shouldn’t be on flights that are that long...I had to nsist to have a miserable cup of coffee. Movie selection was poor. USB port didn’t work. Shame on you!"

Pros: "Nice staff"
Cons: "A little too warm for me."

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

Pros: "Professional courteous staff, and comfortable experience (not easy for a 9-hour flight!). They do not try and "nickel and dime" your for moderate conveniences."
Cons: "Check in at the airport took 40 minutes, for a line that wasn't all that long, mainly due to not having all that many agents available."

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

Pros: "A340 was not the A380 but very nice. Had isle seat and seat next to me was open making for a very comfortable flight."
Cons: "The boarding process is a bit messy. While the lines went fairly fast, the "line" to board by section was all over the place. Would be better to simplify the process and board by groups or at least have a better way to line up"

Pros: "the crew are exellent"

Cons: "Entertainment options were not too good. The flight should have more American sitcoms and more Hindi options."

Pros: "The entire experience was great. Easy check-in, boarding, on time, friendly service, good food, good movies, and overall a really nice atmosphere for such a long flight. Would recommend this Flight to anyone."
Cons: "Nothing"

Pros: "Good food; comfortable seats; not a full flight, so plenty of space to move comfortably. I appreciated the restroom configuration which did not impede movement between seats (in the lower deck). Service was generally agreeable."
Cons: "The flight attendants were cordial, but a little grumpy at times. This may have just been a skewed impression because of language barrier. There really was nothing to complain about."

Pros: "The overall feeling of this flight was 'relaxed'...after getting over the fact, that this was a huge (two story) airplane. Short flight from Denver to Frankfurt...only 8 hours:)"
Cons: "I would have loved to be offered eye shades and ear plus, since most passengers watched movies and i wanted to sleep:)."

Pros: "The people in the crew were very nice"
Cons: "The two seats that I paid for were the worst seats I've ever had in a plane They were the back two seats of the plane they were so small you should not have them there. I am a small person I had no room my wife is small she had no room. When the seat in front of me laid-back it almost hit my chest."

Pros: "Entertainment options were great and always make the flight go by faster."
Cons: "Seat was broken and didn't recline, stewardess had zero interest in assisting. She could have simply told me she was putting in a work order. Only one food was option available, the stewardess offered zero solutions for people with allergies to the option provided. The general theme was that the crew wasn't eager to please."

Pros: "Got upgraded to Business Class"

Pros: "Everything"

Pros: "This flight was fine. About as comfortable as I expected."
Cons: "I sat next to a man who had a vape pen and a can of chew with him. So the entire nine hours I spent smelling his mouth tobacco and I could do nothing about it. It was disgusting."

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

Pros: "No communication"
Cons: "Unhelpful and now luggage has been lost going on 3 days in same clothes"

Pros: "Plane was quite new with fairly comfortable seats. Great individual screens and entertainment. Food was good. Staff was very friendly. I would fly with Lufthansa again."
Cons: "We might try for the direct flight next time (if it is available). Connecting in the Munich hub added a lot of time and some back and forth flying. I wish our Lufthansa flight back was also with lufthansa rather than United. United SUCKS in comparison. United needs to improve their game and their planes and their service."

Cons: "Announcement system sound quality so poor we couldn't hear the onboard announcements. Our flight attendant was not very friendly and he continued to address us in German even after he was aware that we were English-speaking (he spoke perfect English so that was not the problem). He didn't offer brandy to anyone on our aisle after dinner, even though I heard the attendants on other aisles offering it."

Cons: "Nothing"

Pros: "The flight was on-time!"
Cons: "The food was mediocre."

Pros: "The food was very good. The service, the preciseness."
Cons: "I didn't like the entertainment, there should me more options for movies in English and Arabic."

Pros: "Smooth and on-time."

Pros: "Flight departed 30 minutes late (due to a delay with the inbound flight)but a short flight time enabled the delay to be recovered and we landed in FRA on time. A very long taxi (30 minutes) made connection time for my next flight to be very tight."
Cons: "Why do LH insist on serving the 2nd meal/beverage service in economy class until 50 minutes before the flight lands? I suspect they would argue it allows passengers to have greater rest however in Y class the passengers are awake long before......could I suggest serving the snack earlier as it prevents a very rushed service as trays are collected and cabin secured very near to the actual landing?"

Pros: "The crew was fun"

Pros: "I was finally able to sleep."
Cons: "Everything was good."

Cons: "The check-in team at Austrian Air insisted I could only take on a single carry-on, even though I'd come with two. Should be one above and one below."

Cons: "The fees for the sporting bag was out of control expensive"

Cons: "Food is looking not fresh and quality is cheep ...."

Cons: "Poor selection of european films! There is a far bigger choice in e.g. Singapore airlines or Cathay Pacific. Rest was fine."

Cons: "Thank you"

Pros: "Service was very good"

Pros: "Nothing"
Cons: "Flights were late for more than 20 min. in both directions. Almost missed connecting flights in both directions. Had to pay for the luggage at the airport (luggage was not included in my ticket). Flight to my final destination was cancelled (first it was delayed, but I did not know that untill I got to the gate) I was diverted to other country (by other company), had to pay for hotel and taxi, missed almost two days of my vacation. On my flight back home, they have lost my luggage... hope they will find it. Now I am trying to get refund for cancelled flight, hotel, taxi, food... I will never fly with this company by my own choice any more!!!"

Cons: "Seat could be more comfortable"

Pros: "thebflight wqs smooth and on time"
Cons: "snack they gave something sweet at 07:00 AM"

Pros: "Service was outstanding!"

Cons: "Lufthansa’s/Austrian Airlines’s idea of a ‘snack’ is a pathetic little bag of sugar and chemicals that no one should have to be offered, even if it comes for free. Hugely disappointed. Flight attendants not attentive enough."

Pros: "The stewardess is very polite and accommodating n"
Cons: "Nothing"

Cons: "All good!"

Pros: "Staff were always courteous."

Pros: "Friendly staff, on time flight. Nice refreshments"

Pros: "Highly efficient transfer (45 minutes between flights)"

Pros: "Direct connection"
Cons: "Meal is horrible"

Cons: "Long delay."

Cons: "May bags didn't make the transfer and were sent on to me the following day."

Cons: "Cancel it"

Cons: "Chaotic boarding process, no clear communication with passengers, delays in boarding not explained, people sent away or told off, huge attitude and chip on the shoulder. In the U.S., we are customers that paid for a service and are asking for details on that service. In Europe, we are annoyances that depend on staff at the boarding gates to get on the plane, so power tripping and general disdain to customers beings confused are part of the game. I will try never to fly Austrian Airlines again. Absolutely unacceptable behavior toward families, mothers with children, senior citizens. I can almost see the smirks and annoyed and superior attitude of staff at the boarding gate when they had to deal with more passengers asking why boarding hasn't started half an hour ago when we were announced it would. No answers, just show me the passport and boarding pass, ok, please go back, we'll let you know, then ignore questions."

Pros: "The departures and arrivals were on time."

Cons: "Our flight was delayed causing us to take a red eye, missing our connection,long layover, missed our hotel for the night, thripled our time in transit. The worst travel experience I have had."

Pros: "Despite having a delay in Denver, we were able to arrive on time. The crew was very friendly in greeting us as we boarded the plane"
Cons: "The boarding process was hampered by too many people putting too much carry on luggage in the overhead bins. Many put things in the overhead bins that could have been put under the seat. It didn’t seem like the crew was paying too much attention to this. In general the crew was pleasant, but there didn’t appear to be much sincerity in the pleasantries."

Pros: "Boarding was fast and efficient. Everyone went the same time. Had to come in via a small queue and then wait for the gate to open."
Cons: "No food or drinks given at all for free. You had to buy even a soft drink. Not a good experience at all. I waited and bought fast food at the airport after the flight."

Pros: "The crew was very friendly. Lots of movie options. I got a voucher due to the delay."
Cons: "The delay was a bit of a bummer and it would have been nice to be compensated with more than a voucher that couldn't be used in LHR because it was in USD. I also would have liked to been told they were still planning on serving dinner despite the midnight departure; I fell asleep because they turned off the cabin lights and I assumed the meals had shifted, but instead I missed out of my dinner. Lastly, I am quite petite and still struggled with legroom."

Pros: "Orderly boarding and disembarkation."
Cons: "This airline is one of the worst in Europe, for the simple reason of putting short-term profits ahead of decent treatment of the customer. My flight across the Atlantic was 4 hours late, and BA refused to put me on the next available to Prague, even though the lateness forced me to miss the BA flight I have been booked on. Their reason referred to a technicality in the booking procedure, but actually BA has put in place "policies" aimed at their financial advantage, over and above reasonable treatment of the customer. BA's refusal to rebook me cost me a lot of inconvenience (3 hours on the phone, for one thing) plus about $150 (I am taking another route to Prague); BA was then able to sell both my original seat and an extra seat on the next flight from Heathrow to Prague. I will never fly BA again in my life if I can help it."

Pros: "Interior"
Cons: "FLIGHT WAS CANCELED"

Pros: "Service is good, people are friendly. Efficient. Keep you up to date with changes."
Cons: "No complimentary beverages. Not even water. Baggage did not make it."

Pros: "The crew was friendly."
Cons: "The flight was over two hours late. No USB ports for electronics. Leg room and seats were dismal."

Pros: "They were extremely accommodating."
Cons: "N/A"

Pros: "it was very clean on a board."
Cons: "even water for money"

Pros: "The plane wasn't full, so there was an empty seat in-between my aisle and their window, as well as open spots throughout the plane."
Cons: "Plane was delayed several times. Website wasn't clear about what time to show up to the airport. Food was served late and was mediocre."

Pros: "Excellent food and service."

Cons: "Tight seating altho many open at rear so was able to move there"

Pros: "Treated coach like first class."
Cons: "Nothing"

Pros: "Boarding went fast."
Cons: "Too tight, not possible to sleep a little bit."

Pros: "Nothing"
Cons: "I didn’t like that I paid for first and received terrible service in the air and on the ground"

Pros: "Food was delicious and out flight attendant was very helpful. Plane was quiet and the movie options were good."
Cons: "Plane was honestly very dirty. There was a ton of crumbs and gross stuff in th seat back pocket. Which I did not even use because I didn't want any of my things to touch. The overhead lights were covered in dust. So make sure you have some some type of cleaning wipes with you!! I do understand that I was flying economy, but that doesn't mean nothing should be cleaned."

Pros: "Good food"
Cons: "Long transit at Heathrow airport"

Pros: "Clean plane"

Pros: "Awesome flight attendants, funny relaxed, seemed like they wanted to be there"
Cons: "The entertainment was awful. A small screen with terrible picture. The movie selection was small but current."

Pros: "Seats were comfortable and staff was very attentive as well as respectful of us when I was sleeping"
Cons: "There was condensation leaking from the ceiling of the cabin. A crew member said this was normal, would have been nice to know this ahead of time to reassure me that for a first-time overseas flier that this is normal."

Pros: "Nothing"
Cons: "Late"

Pros: "A good trip"

Pros: "Cabin crew was friendly and accommodating. Flight was on time and landing was excellent."
Cons: "No complaints"

Pros: "Service, food, safety video"
Cons: "Delayed flight"

Cons: "The seats on these flights are poor. As well as being narrow, there are bars on either side that dig in to your sides. My ongoing one hour domestic flight had more comfortable seats. Fod choice poor. Chicken Curry or Cheese/Tomato Lasagna. If I want a vegetarian meal I'll order one beforehand. Give me two meat options. This isn't the first time I've noticed this. Is it cost cutting? Seems like it to me. Not impressed."

Pros: "Very courteous attendants"
Cons: "All good"

Pros: "Very little."
Cons: "Flight was delayed. The seats are uncomfortable and too small for even normal size male. Food was disgusting. Staff were very nice and helpful if asked. I think all the space and comfort were in buisiness and first class. Economy class is still paying for a ticket, make up most of the passengers and deserves better. Getting into a seat was like getting into a straight jacket."

Pros: "The food was better than expected and the crew did everything they could to keep us comfortable"
Cons: "That plane was so gross. The upholstery was stained and frayed. It was also insanely small. Holy cow!"

Pros: "not much"
Cons: "5.5 hours delay"

Pros: "Just so comfortable and friendly. I'll fly them again next time!"
Cons: "Nothing."

Pros: "I loved the legroom in the emergency seat I had and the service was top notch. The food and food choices was also really nice and the wine served with dinner was great."
Cons: "Overall loved my emergency row seat the only negative for my particular seat was once the rest of my row was filled in and the 2 seats in front of me it made it impossible to get out of the seat and stand up unless I could had the person sitting in front of me get out of his seat."

Cons: "They don't even give you water without charge"

Cons: "You lost our bags..."

Cons: "The BA agent Giles, was rude and spoke to us condescending. His inept handling of rescheduling my family caused us to not only be split up in our flight from London to Vienna, but the majority of us had to wait 10 hours for the next flight. He could've rescheduled us together, but instead he ignored my sister's request to do so, rudely told us to get back in line, and rescheduled another family on the same flight as my sister, thus eliminating our seats together, and forcing her to travel alone."

Pros: "Nothing"
Cons: "Old plane, flight attendants boardering in rude, very poor food (!), de-plane via steps to the tarmac and at least 7 coaches at Heathrow (an aged 747, so it took nearly an hour!)"

Pros: "Everyone was awesome"
Cons: "The staff was awesome"

Pros: "Everything was ok."
Cons: "Delay."

Pros: "Crew"
Cons: "Delayed"

Cons: "Charging money even for a soda. Seriously so cheap."

Cons: "We purchased upgrades to an exit row seat because my knee locks up when cooped up for that long. They changed the plane and I understand that happens but they denied our refund request with 7 days deadline to re-request. So now we have to spend valuable vacation time dealing with their incompetency"

Pros: "No turbulence!!!"

Pros: "For economy class it was good seats (bulkhead), the crew were nice, and the food was good."
Cons: "The tiny screens for movies were awful. Worst of all, the horribly loud voices that nearly break eardrums when the crew comes on during the flight was both painful and annoying."

Pros: "Easy and quick boarding. Dinner tasty, but it is hard to cut a fillet steak without hitting the next passenger in the elbow"
Cons: "Only one check-in agent running all desks including bag drop - long wait. 19 year-old 747 had narrow seats in premium economy, uncomfortable and too much body contact with adjacent passengers. Outbound to SFO in an Airbus 380 had sparkling wine pre-take off, hot towels twice, this DEN-LHR flight only had juice or water on offer (crew said "don't serve that on this route") no hot towels, crew's objective seemed to be get around cabin in one go and leave Pax to it Breakfast was abysmal, soft-pretzel roll, no juice or water served, just indifferent coffee"
