Schedule and on time departure and arrival were great. The crew was good, but a change in aircraft bumped many of us from our expected seats. It was a crowded flight, but the cabin crew did their best to keep things under control.

Schedule and on time departure and arrival were great. The crew was good, but a change in aircraft bumped many of us from our expected seats. It was a crowded flight, but the cabin crew did their best to keep things under control.

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

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

I bought the ticket a month before my flight but checked in couple hours before my flight and had to wait seat assignment just before take off. On top of that there was not enough room in the overhead bin for my luggage.

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

Tight connection from Austrian Airlines made this challenging. Our luggage did not make it, delivered the next day at noon. Flight itself was very full, not especially comfortable.

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.

Overall pleasant flight . The lunch was exceptional! Delicious chicken curry with perfect rice and amazing chocolate (Sacher torte) for desert. I have not eaten such a good airplane meal in a very, very long time.

Flight attendants were awful, very rude and inconsiderate for mothers with small infants traveling.

I been flying with Austrian for few years, they never failed me.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

T hey did a great job. Flight was on time .

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Touchscreens do not work. WiFi did not work. Food is possibly the worst on any European airline. Drinks came by only four times on a cross-Atlantic. The plane was two hours late because—it was announced—Lufthansa didn't have enough large aircraft in their fleet to accommodate an on-time flight.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

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!

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Coach seats are too tight. Seem designed for small people. Food different but OK. Staff helpful.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.
