No delays, helpful staff, well organised. The check in and boarding procedures ran smoothly. The only thing that put me off is that the meal had spicy peppers in. I would have appreciated at least a warning (if i couldn't have a choice) so as to simply not eat them because they were too spicy.

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

Austrian airline they cancel my fight , and the couldn’t give me flight , they said only available flight 4th and after , I sacked for refund, even from you KYAK , and tell now no any refund , because what happened I lost more money because I have to stay in hotel and then I buy new ticket

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 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.

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).

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 restrictions regarding carry-on baggage is too strict. My wife was forced to check her carry-on bag. Never had this on other airlines.

Second time I took this flight, and they lost my luggage both times. Waiting for my suitcase now, last time it took two days to get it back.

Everything could be better. The plain was in Orlando for 3 hours prior to boarding. After boarding all the passengers they found out that plane has a mechanical problem. After an hour the problem was solved, the pilot comes on and states, (We have to go back to the gate and take on more fuel!) Are you kidding me???? Who they have for pilots, Boy scouts?? I barely made my connecting flight to Vienna, but my suitcase did not. I'm still waiting for it, in Gyor, Hungary. Am I having fun yet?? Other passenger were in the same binned. I travelled all over the world both for business and pleasure with all types of airlines. By far of all the carriers I travelled with, Discover is the worst. I'm contemplating to bight the bullet and go back to the US with a different carrier. For International flights, the seats are made for little people. The person in front of me had his seat reclined the whole way, I felt like he was sitting in my lap. For closing, I would not let my dog travel with Discover, yet alone recommend it to an other person. Does it sound like I'm frustrated, Think about having to travel back to the US with them. I'm sure I'll not hear back from you, because nobody wants to hear about bad news, but with all the hype Discover puts out there about their services, nothing could be further from the truth.

Only problem we experienced was not anything to do with Lufthansa. When changing planes in Frankfurt we spent over an hour on passport control line. Lufthansa did a marvelous job on everything from keeping me informed via texts, to terrific cabin crew.

Bordón could be bettet if the company say before boarding the order of the different groups.

Checked in is easy and it was a smooth flight from LAX to Munich

There is no recline on flight from DFW to FRA. Middle eastern airways provide better recline option for the same class. FRA to Bangalore has better recline option. I bid 100$ for premium economy, my request was declined. But staff handled it without issues.

The Lufthansa part was wonderful. The short connection flight was not.

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.
