It was a short flight. Plenty of room on the plane. It was also extremely clean.

I arrived late in Frankfurt and I had to catch my flight to Vienna and I was running late because when I was landing the flight to Vienna was boarding. I had to go through immigration and then I had to wait in a long line to take a bus to a terminal where my flight to Vienna was taking off. However, I truly didn't think I would make it. I was literally running through the whole airport and when I stopped to ask at one of the Austrian Airlines gates they were rude because they didn't have the time to support me.

They were late and I missed my flight for Chicago. Terrible experience with Austrian airline this time.

They separated me from my kids We were checked in to fly from Vienna to Frankfurt and Washington DC final destination but separated my wife and kids sent them to Barcelona instead then Washington DC They end up traveling for 26 hours Horrible experience Never Austrian Airlines/Lufthansa again!

The flight didn’t happen with Lufthansa. It got canceled with no reason given and all I received for my troubles was €20. People make travel plans for a reason and when the flight was rebooked, it was delayed for 4 1/2 hours on Austria Airlines. The flight attendants were of zero help. They just wanted to stand and look pretty. I hope to never fly Austrian Airlines again. Horrible!!

Food selection wasnt great, even for flight meals. However staff was e extremely pleasant

Lost my luggage and still not found to this point.

was having emergency they keep dalying the flight I miss hull my trip and united airline charges me &100 for bags and I spent more thin $320 at airport for my family and when I get back samthing Daly my flight in muc I lost flight in Chicago I spent another &220 at Germany airport for no reason I should get refunded it’s very hard when total off us 7 people buy food at airport

The plain was on time. Better seating, better service than Discover. I wish I could used them for my return flight. I have used them before, and they were always good.

Great, the staff the service and everything was very good, without delays very comfortable.
