Pros: "I loved the service. All of the attendants were really nice and helpful."
Cons: "My tv on both 12 hr and 8 hr flights didn’t work well and the food wasn’t the best. Also they ran out of food options when they got to me twice."

Pros: "Qatar has the best crews. The 777-300 is the most comfortable aircraft I've ever flown on, and I'm always in the cheap seats. Plenty of food."
Cons: "Some of the food dishes weren't appealing to me. But I get that trying to please everyone with everything on diverse international flights is impossible."

Pros: "Video on Demand at each seat in coach. Friendly staff. Also patient staff, what with the languages they have to cover with each flight. The airline goes everywhere so it’s impossible to say what anyone will be speaking."

Pros: "Individual service, happy and natural looking crew, comfort and company aim."

Pros: "For the most part the crew were very helpful."
Cons: "Food quality and quantity."

Pros: "In-flight treatment"
Cons: "The seat"

Pros: "Great flight. Everything was good. The only very small issue is hey offer WiFi but even if you pay the allocation of data make you feel like you living in the 1990. 10 meg free and 300 meg for a whole flight is a complete joke, especially for USD 30. They could manage protocols but give a reasonable service."
Cons: "WiFi"

Cons: "Na"

Cons: "Nothing disposable about the airline but booling process gave me a headace"

Pros: "Overall nice"
Cons: "Same as above"

Pros: "Excellent service"

Pros: "The staff is friendly and attentive. Food has been flavorful and consistent in quality. Blankets and pillows have been clean. The energizer juice was an excellent option."
Cons: "The cleaning crew was in a hurry and there was a used cotton ear swab in the remote armrest. The tray did not close snugly back when closed up. The remote buttons were not quick to respond and needed to be pressed firmly and slowly. The food menu needs more lighter options. The toilet could use mouthwash addition."

Cons: "Food"

Pros: "Very nice arrangements, the seats were comfortable, the food was delicious, and the staff could not have been more hospitable. I would be delighted to fly with Qatar Airways again."

Pros: "On board crew are excellent."
Cons: "Ground staff requires training specifically on communication related to boarding. Travelers were confused as to what zone is boarding at a given time as there were no announcements. Pathetic boarding process."

Cons: "Not that many choice in movies"

Cons: "It was all good"

Pros: "excellent services from top to bottom cabin crews.Salute to Hats off them."

Cons: "Flight delayed Stewards were rude"

Cons: "Boarding in India is never smooth, no difference here"

Pros: "Everything was great except Food and service comfort of the plane Cleanliness was superior"
Cons: "One crew member was a pain if you wanted ice you got 3 cubes ask for more he would ignore you. He was rud and nasty. I mentioned to other crew members they say just his way. If that is his way maybe he need find new job."

Cons: "I was Told the flight form Doha back to Houston was over booked so I had to get re-routed through another city. For a $6,600 business class ticket this is very bad form."

Pros: "I liked everything about it."
Cons: "My trip was to long but it wasn't there fault. I was so tired."

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: "food"
Cons: "Worst customer service ever seen in my 15years of flying experience. Initially charged $1000 for 3 tickets for modification of return trip - confirmed the same and tickets issued (i'm fine with this). But, after i made arrangements for new date, I got a call saying calculation error and asked to pay another $500 leaving me no choices. How can such a reputed airline have no tools to calculate the pay? Other airlines offered one-way for half of the price i paid. On top of it, online helpdek promised front line seat to satisfy me but nothing was offered even if i ask explicitly. Simply declined saying i am not in priority list. Why do they make false promises? Friends, Just don't fly for food ....."

Pros: "Nothing at all"
Cons: "Poor management didn't provide a hotel for layovers more than 12 hrs"

Pros: "Everything"

Pros: "1. Comfortable. 2. Good crew 3. On time 4. No hiccups."
Cons: "1. Not having wi-fi (major) 2. No news channels in in-flight entertainment 3. No snacks"

Pros: "Food and drink options. Courteous."
Cons: "Smells from others"

Cons: "No internet"

Pros: "Nothing"
Cons: "The codt of the ticket has been deducted twice from my account. So I paid double of the price. Please thankfully correct this mistake to continue using your services. Regards"

Pros: "Not a lot -14 hrs in cattle class is no fun."

Pros: "Curious crew."
Cons: "Nothing"

Pros: "Nothing"
Cons: "Flight was not on time so I didn’t make the rest of the flights. And tbd new airline lost my luggage."

Pros: "From start to finish, Sevdije was in great hands. She had to be in a wheelchair, and there were three connecting flights in countries where she doesn't speak the language. It could have been so complicated, and everyone made it SO EASY. She was all smiles when she arrived in Boston. THANK YOU!!!!!!"
Cons: "Nothing!"

Cons: "Passengers should be notified of the process of changing airplanes at Vienna. What a nightmare. We were scheduled for 50 minutes between flights. Not really enough. If we were aware of what was required it may have helped, however the distance we had to walk was rather extreme."

Pros: "They were really good with checking in my excess baggage and my two cats. Cats travelled well and arrived as expected. Check in at O'Hare was very friendly. In the air, flight attendants were very accommodating and friendly. All luggage and cats arrived! The plane from O'Hare to Austria was very nice!"
Cons: "I think I have gotten used to Asiana's and Korean Airlines'. It just didn't seem to measure up to their business class service. The food (which has been highly rated!) I found to be just mediocre. Maybe it's because I was living in Asia for eight years and had become more accustom to asian cuisine?? I didn't love the seat either. When you recline, your feet are cramped inside a small area under the seat in front of you. It was cramped. The ability to customize the seat recline was limited. I like being able to move the head and feet into my own customized position. The business class seats from Vienna to Amman felt like coach."

Pros: "Seats more comfortable."
Cons: "Flight left late. Unboarding took a long time. Didn't hold connecting flight, missed it. Now on 5 hr wait and may miss airport transit."

Pros: "Had 45 Min to connect at vienna airport and our first flight was delayed so we had to run to get in time to the gate. Literally the gate was on the opposite side of the airport. Bad logistics"

Pros: "Great staff, good meals, snacks, and drinks thru the entire flight."

Pros: "Fast disembark. Used both ends."
Cons: "No entertainment. Luckily, it was late or I would have missed it because my previous plane was so late."

Pros: "next leg of journey- was delayed three hours and NO one was able to reschedule flights"
Cons: "That flight was delayed for three hours! Causing me not to be able to make connecting flight. No help in Vienna."

Cons: "Checked baggage very expensive."

Pros: "Great food. Exceptional service. Clean airplane and toilets. The whole flight was smooth and comfortable. And we were in coach!!!"
Cons: "All was great."

Pros: "Macedonian staff were very helpful when I arrived early to get me checked in and situated"

Pros: "Crew only offered water once during the whole night flight. The entertainment programs regarding games was very restricted, both in terms of game offers as well as operation / handling"

Pros: "The flight was comfortable and very timely."
Cons: "Very little leg room."

Pros: "Very well organozed"
Cons: "None"

Pros: "Got to destination safe and sound and was thankful for that!"
Cons: "Boarding was messy. Food was ick- "chicken" tasted like a grade d boiled chicken nugget, terrible texture. Ladies on flight were kind, although not terribly helpful. Movie selection was pretty small and lots of Rated R movies, hard to find anything in the middle (not kids, but not adult)."

Pros: "The crew was wonderful, as is always true with both Austrian Airlines and Lufthansa."
Cons: "The inflight entertainment included so many mediocre films, with hardly a classic among them. I suppose those are cheaper, but I would think both Austrian and Lufthansa (they seemed to be using almost identical entertainment systems with almost identical offerings) would benefit from limiting their movie options much more towards movies with, say, above a 70% Rotten Tomatoes rating or above average box office sales. Even if they had fewer films, say 40 instead of 56, the ones they have would be more popular."

Pros: "they asked me if I wanted an upgrade to business class - nice"
Cons: "they left all the lights on in the plane - difficult to sleep at night. Never had this happen before. Another lady from N.J., originally from SLovakia and going to Kosice for a visit complained about the same thing. SHe was worn out and so am I."

Pros: "My flight from Vienna to Warsaw was fine."

Cons: "LOST BAGGAGE !!!!!!!"

Cons: "Boarding in Vienna was completely unorganized. Received zero instruction from crew on new boarding information."

Pros: "Efficient crew, good meals,on time arrival."
Cons: "Took a while to board and could use more updated films-minor details."

Cons: "Flight was cancelled and we weren't notified."

Pros: "Most of the crew were nice. Efficient."
Cons: "Ridiculously small seats and legroom."

Pros: "No stops"

Pros: "After departing the cluster fk that is O'Hare airport it's such a pleasure to interact with Vienna and Austrian Air. I had 'only' an hour to make the connection, and yet all, that is all, formalities took no more than 10 minutes. I had plenty of time to spare. Waiting area at the gate had plenty of seating and the staff was professional and courteous. We had to gate check bags as the plane was a regional turboprop, but everything went very smoothly."

Pros: "The service was good, everyone from the staff extremely friendly and overall the flight was very quick."

Cons: "Oversold the tickets on my flight and put me on standby. Needed to change the flight and all my plans."

Pros: "The food was very good! And the movies you could choose too."

Cons: "Technical issues with website and online check-in. Boarding was poorly organized. Food could be better (e.g, breakfast muffin was terrible). Also availability and varienty of alcoholic drinks could be better. Flight was delayed and therefore my luggage didn't make it to connecting flight.."

Pros: "Food, wine, crew, physical comfort were outstanding. Excellent overall! Austrian continues to abide by the highest standards. After 14 years it still is one of our two favorite airlines in the world."
Cons: "Boarding was chaotic, cramped. Passengers kept lining up only to be sent back to the end of the line after documents were checked three separate times. Only first class passengers were allowed at the gate. Chaotic and frustrating. Not what one would expect of Austrian efficiency!"

Cons: "It was almost 2 hours delayed"

Cons: "Not a lot of legroom and they should have provided an additional snack during the flight. Did not like that in order to select a seat prior to the check in period I had to pay for the selection."

Pros: "Decent between chare distance for a medium sized airplane (A321)"
Cons: "40 minutes late, no entertainment, mediocre lunch, not enough space in the compartment for hand bags"

Pros: "Flight services were good. Staff friendly. food was good"
Cons: "Maybe I was upset due to the issues at the first leg so could not enjoy this one"

Cons: "Policies on bringing stroller differed between each trip. And they were not polite about it."

Pros: "Clean aircraft, very nice crew, nice airport (Vienna). Always enjoy the flights when I'm heading towards home...."

Pros: "More leg room than we had on Swiss Air from Chicago to Vienna via Zurich. In flight food was excellent. Staff was friendly."

Pros: "the flight seat was comfortable. It was the most comfortable economy class seat."

Pros: "Everything worked well."
Cons: "No sleeve at Tel Aviv. disembarked by stairs and a bus to the terminal."

Pros: "Reasonably on time. Food and service were passable."

Pros: "Flight was faster one hour then expected"
