Horrible experience. Nothing to give to kids to keep them entertained.

Trouble keeps changing the time and I was booked different flight without knowing it was bad experience

Hated every minute of it. Delayed for over 10 hours only to have to cancel rental car, car insurance and hotel. Its taken me 3days to get to my final destination when it should have only taken 12-14 hours. Very unhappy with Lufthansa.

This flight is always a cramped bus. The gate area was inadequate and announcements were hard to hear. The flight was delayed 45 minutes to an hour by a broken aircraft door, making our total delay from Vilnius 5 hours.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

You need to reimburse me for my seats purchased and luggage.

Flight delay wasn’t managed well. I was booked for the next flight for 2 days later!

My baggage has been lost for the last 6 days! The problem originated at LAX with Lufthansa, which was a very big disappointment from LAX to Munich. The flight was delayed over an hour, the overhead bins on the window side are too small for most carryon's, the in-seat video screen were very poor as they would not respond to your touch quickly and would stop and start all over again, the earphone jacks are not like most standard ones, the seats still has wrappers and trash in pockets and on the seats. and there was no USB outlet to charge your phone or other devices. The German reputation for quality is bogus with this airline. BUT the responsibility for delivering my luggage became Air Dolomiti's as they were the last leg of the trip. The baggage area was chaos because several flights arrived at once. I took me over an hour to file a claim, the agent entered my info incorrectly, and the contact numbers for Lost and Found at the airport was never answered. I have never been called by Air Dolomiti or the baggage delivery company. I had to do all the calling. AD's live agents gave me two wrong phone numbers for the baggage company. When I finally got the right one on my third call, OF COURSE, no one answers and I still do not have any information on when my bags should arrive. VERY UNPROFESSIONAL operations by Lufthansa and Air Dolomiti. I will make sure I book any other air carriers on the rest of my flights to Italy this year.

plane was late. flight was very bumpy most of the way

Seats on the A320 were more comfortable than the A330 I took from RSW to Frankfurt

Ok, but no entertainment. Left late, but made up most of the time.

May be it is not an ITA issue, but the bags took long time to go out.

Good. But there food was poor quality and 95% of movies didn't have English subtitles

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

Service from staff was poor, food choices were limited. Air plane was not clean or hygienic and seemed like not cleaned for days. Seats were uncomfortable.

service from stAff was barely there , food choices were limited. AirPlane was not clean and seemed like it was not cleaned for days.. Seats were very uncomfortable.

I paid for premium seats and the last minute they changed the aircraft for a bigger one, they bumped me to another seat which was NOT at all comfortable for an 11 hour flight, will fight for a refund!!

The landing was catastrophic. I was very scared. I thought it were my last lminues. Pilotes should be more experienced

ALL services were good. An announcement should’ve been made at the end of the flight that filling out a customs form would not be necessary anymore for USA travelers entering Philadelphia.

The flight was smooth, the premier economy seats were comfortable, the flight crew were excellent. The on board food, however, was AWFUL. I suggest bringing your own food on board.
