The crew was attentive but not intrusive, and was always kind in every interaction.

Austrian was not the issue. Kayak was terrible The flight was canceled. Frustrating but it can happen. The worst was Kayak's customer support around re-booking. I have chatted with a bot, than with a person who insisted the flight was still on as originally booked. while chatting i went on Austrian web page and told the kayak chat lady that the flight is shown as cancelled. She said she will escalate this and that someone will contact me within the hour. When I have asked her to give me the details of the flight she sees, She gave me the general A to B and return B to A. Totally unhelpful. After two hours I contacted them again, They were still saying the original flight is as scheduled and when I explained again I was told I will be contacted within 2-6 hours. NO ONE CONTACTED ME EVER SINCE! I have than contacted Austrian directly and was rebooked on a difficult flight. Kayak continued to send me irrelevant updates about my original flight. Terrible customer service at time of need.

From all the segments I flew it was the only one I did not get the option to choose ni seat, I did not get the quality of seat I had paid for. Crew was nice, airplane was clean, but no food, only water and a small courtesy chocolate. Everything else you had to pay for.

the flight was canceled, and I had to stay more than six days at hotel . waiting . then I had to buy new ticket. really it was very bad experience, and I lost a lot of money and time , and your airline said sorry

Management and staff att viena wasn’t professional,and they are not good by how to communicate and solve the problem, I was shocked , as I know Austrian airlines was amusing Thank you

The baggage arrived damaged and i spent EUR 300 on the baggage a month ago. No responsibility from airline or the handles.

Premium Economy is good value in comparison to Business Class. Not all the perks of Business but a lot of leg room and wider seat and elbow room. Food was very good. I even asked for a Gruner Veltliner wine which was not on the trolley and the attendant went into Business/First to get me a glass. Nice little touch. I would like to have a wider selection of music -- more 70's-80's (guess how old I am).

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.

It becomes like Wizz air, no good, bad comfort and you should pay for 20kg bag.

I am Star Alliance Gold which meant nothing at security as my partner, who was on the same ticket, couldn’t come through with me which meant I had to wait for 20 minutes for him to join me. For a hub airport the lounge was small and uninspiring. We told staff of our security experience and they informed us it was like this for everyone. Isn’t this is an Austrian Airlines hub? Boarding was a nightmare as there was only one person at the gate and again, I had to go through without my partner. The boarding was supposed to be in groups but a bunch of travellers with lower groups were crowding the entry level. After I managed to get through I found myself on a bus waiting with 3 others for 15 minutes as the checkin had failed. Then only to find everyone else coming onto the same bus. My partner and friends actually beat me onboard. The crew were young and unable to control the crowd allowing people to stand in the rain instead of getting people to their seats promptly. During flight we were only offered a cup of water & a chocolate. Not impressed with Austrian Airlines or their Vienna hub airport and plan not to use them again if I can help it!

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.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Never flown with LH before so all in all wasba good experience. Also good to know that approx 24hrs prior the flight opens up for being able to organise the seating free.

This flight space was way better than our international flight. Efficient boarding and comfortable

It was a short flight, no real service (which is okay). Very bumpy because of weather.

I'm Canaadian. I hate Air Canada. I used to give them a pass on their international service. No longer, They suck across the board now! Old planes, exhausted staff bad food and shitty entertainment. Your seats need reupholstered! Start with that...

Good experience. Food was great and passengers helped rearrange seats so our family could be seated together

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!
