Just overall a poor experience with little to justify the price of the ticket!

Flight delayed with no explanation. Boarding was confused (proceed to plane, go back to waiting area).

Great! They got my vegetarian meal right, flight was comfortable, they helped store my heavy luggage. Pleasant crew and flight staff.

The flight was delayed for 30 minutes with no apparent reason. There is no entertainment at all, and no USB or electric outlets for charging your phone or tablet.

We have travelled on 13 December with Austrian Airlines from Yangon through Bangkok and Vienna to Varna. The first flight operated by Thai Airlines was nice and comfortable. I wouldn’t say the same thing about the next two flights which were operated directly by the Austrian Airlines. During our flight from Bangkok to Vienna:  > The service was very poor – serving of food and drinks was disorganized, late and not combined, the stewards were walking back and forth without doing anything substantial for the passengers. Even the morning breakfast was very late with a cup of coffee almost while landing (after a reminding).  > The food itself was OK-ish but for a 12-hour flight, there were no snacks/bites in between dinner and breakfast as it is with the other airlines.  > The cutlery was wooden, most probably recycling, but very unpleasant to eat with.  > The stewards were not rude but not friendly and/or helpful  > And also, half of the passengers had travel sets, others did not. The flight from Vienna to Varna was another surprise: firstly, the flight was late and secondly, they were serving only water free, even the coffee was paid, so were the snacks, but we had to pay to reserve seats. The whole experience is as if it was a low-cost airline. All in all, I wouldn’t recommend using the services of Austrian Airlines: the ticket prizes are quite the same as of the other carriers flying to this destination and you would have much pleasant time.

They never gave any meal during the flight. We’ve flown for years and then doing this now is ridiculous.

My flight was changed, you over charged me for a change fee and seats that I did not get, I was out on standby with Austrian airlines. You stile $600 from me.

Very nice and comfy flight , and sharp on the time

The flight was late. We accommodated other missed flights, and the plane was full of people, without space to store carry-on luggage. They lost our checked luggage for the entire flight and delivered it after two days.

There were a number of passengers scheduled to transfer to the flight from Vienna to Warsaw. None of them made it because the crew failed to assist them in getting to the gate for the Warsaw bound flight in time. It could have been done very easily with proper assistance.

Turkish Airlines made a long flight from YVR to IST a great flying experience. From the attendants, to the food, to the entertainment program to all the extras, a twelve hour flight ‘flew by’. Late departure and arrival was not the airline’s fault.

Boarded via bus instead of the air bridge Had to wait 10mins in the bus at the tarmac before we were allow to go up

The flight attendants were great! The seating for business class is better on other airlines. The food was also good!

Great food, great entertainment and very helpful, caring & attentive staff.

Food is getting worse. They use to be different than other airlines. Their economy classes food sucks. Stuff was very helpful.

Horrible, they forgot our luggage, the food was terrible, the crew were rude, the flight was delayed, I hated every aspect of this flight

The flight was delayed so connection was missed. In Istanbul we were taken to a hotel and no one in the hotel knew so we had to wait hours in the lobby of the hotel while the airline and hotel coordinated. The airline staff is rude at times

The checking line was very long , when checked the bags and got the boarding pass but moved fairly fast . The boarding line was long and the ground crew didn’t provide priority to kids boarding . But the air crew on the plane were very nice and polite . Too bad my daughter’s table try was broken which made the trip less enjoyable.

Food could have been hotter. More padding needed in economy seats

Sadly, the plane was extremely old and uncomfortable. The entertainment system broke down completely. We couldn't even charge our phones. The seats were also very uncomfortable, with a very slim seat cushion. It must be the result of having 9 seats where there used to be 8.

Terrible! Our flight was cancelled. No other nonstop flights available. Had to rent a car and drive 7 hours!

I really enjoyed the delicious food and the delicious breakfast; I also liked the seat—it was very comfortable—and the service was absolutely wonderful. The trip was smooth.

The food was awful. It had more than 2 hours delay. It was too expensive

They are offering less and less for more and more. They changed our seat that we paid extra to select at the last minute. The seats are way too narrow and my elbows went numb.

My original flight was canceled the day before due to mechanical issues. I had to rebook and spend $129 for a night at the airport Comfort Inn.

Cancelled flight, had to rearrange plans independently and no vouchers offered

lack of older, great films. Too many child-oriented films. Calculate your % of children passengers, which will be minor.

Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

Didnt make it on flight. Flight was delayed. Then had to get rebooked for a flight that was 8 hours later. Guess who had to wait for 8 hours at the airport?

I never got to Lufthansa because of Air Canadas negligence.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

Try to humanize onboarding and take AI out. It's embarrassing and useless

no kiosks to check in with- it’s 2024!!! the flight was so hot and uncomfortable - not sure if that’s what caused a lady to faint during the flight but i was absolutely miserable.

I really like it and travel to Europe and back with Lufthansa, but it is getting expensive, a bit beyond my me

Not available crew to load the luggage for all the passengers,comon situation for local European destinations , not acceptable situation, never Lufthansa again 😉 🙄

Flight was overbooked. Crew did a great job but passengers weren’t nice and really not patient. Flying in these times is not the best idea tbh.

All good, professional service, and arrived close to on time.

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

Need thicker and wider blankets. Food was below standard especially in the fist leg.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.

The seat was a bit crowded since the person in front was reclined. It’s my personal belief that if the seats are allowed to recline, there should be more room. The service provided by the crew was the best I have experienced.

The onboard service makes it extremely difficult and slow to go to the toilet

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

Amazing crew - they were exceptionally nice. From ground staff to the plane

Small overcrowded flight with limited overhead storage bins. The last row 30 has no windows. The aircraft has no entertainment system. The flight is 3+ hrs and is not a low-cost, but the free snack is a laughable size: a SINGLE bite soft cake/pie.

The seats were quite uncomfortable. I felt like I was leaning forward the entire time, which was quite bad for my neck.
