The tv and remote didn’t work. The plug to charge our phone didn’t work.

Never made it to Lufthansa because of Air Canadas negligence.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

There is more space in this economy seat. It felt like a better layout, not so cramped.

The staff was not at pleasant as those on the first leg of our trip.

Crew was excellent. Sat us together after the airline changed our seats. This was the smaller plane/shorter flight so no entertainment or food.

Boarding was one hour late. Gate notification was incorrect (notification said gate 17, actual was gate 14). Took shuttle bus to board the plane. Late arrival of plane at Turin impacted travel arrangements to the event.

They canceled our flight right before it was to take off and then we stood in line for four hours to make other arrangements. It completely ruined our trip.

Lufhtansa has and can do better. The food was inedible. No individual light for reading.

Flew Premium Economy. The seats were comfortable and tilted back far enough to sleep. Food was okay and service friendly and efficient. We bought tickets through Kayak partner Underpricer and the price was good.

ITA has these new Airbus A330 Neo that hates economy class passengers. The seats have absolutely no cushion to a point where it hits your spine constantly and reminds you to fork out for premium economy or don’t travel next time. The food was absolutely horrible, ETA mentioned 3 meals for 12 hour flight but it was mostly 1 meal and 2 light snacks. I am vegetarian, so my 2’d food was 1 slice of tomato, 1 cucumber on a dry cold bun. The other 2 meals were disgusting. My young one threw up the entire time. Flight attendants were the cherry on top - plain bad. They would skip servicing drinks to some passengers completely and if you call for an attendant, they will come and stop the button on top without even asking you what you need. I would avoid ITA by all means - there are plenty of options including SAS for same routes with better seats and humane treatment.

Nice flight. Uneventful, very good crew, comfortable seats. Pleasant experience.

ITA cancelled fligh rebooked with Lufthansa. Flight good, but 2hour connection in Frankfurt was HORRIBLE, took 1.9 hours to get through scanner, customs, another security, got to gate after running all the way, so caught it but stressful and terrible start to trip.

The boarding process was organized and efficient, and the crew was friendly and attentive throughout the flight. Food and drinks were typical economy class, but good. The aircraft was old, and the restroom was not very clean. However, we arrived on time, so overall the experience was good.

In Prem Econ, safe and timely flight, good amount of space, mostly comfortable seats. Little irritants: When lying down, seat kept shifting on me...as a short person w/light weight, my seat often reverted to semi-upright. Footrest was broken. TV screen didn't work, after I asked a few times a FA rebooted it to work again. And food was marginal. I don't expect much from airplane food...surprisingly, ITA didn't even meet expectations.

Flight was canceled. Rebooked on Lufthansa Also Canceled. Had to pay 3000 more per person and fly Alaska to EWR and fly emirates to Athens.

Our flight was cancelled the day before our trip and we we put on a Turkish Airline flight that got us in half a day later.

The flight I initially booked from Los Angeles to Florence. I made sure had a layover of about 90 minutes in Rome, so there’d be enough time to connect. A couple weeks before the flight for some reason I was updated that that flight had changed and I was only gonna have 60 minutes to connect. From LAX we were delayed by 45 minutes meaning making the connection was unlikely. The crew informed me that my connecting flight would not wait and they would rebook me on one four or five hours later. I wasn’t happy, but I accepted it. It is what it is. Except when we got closer, two separate flight attendant approached me eagerly and said they had great news that my connecting flight would in fact wait for me, but I needed to hurry through the airport so they didn’t have to wait too long. I was first off the flight. I ran about 4000 steps. And got through passport control all in under 15 minutes. When I arrived to my gate, I was greeted by a flight attendant there who was completely indifferent, said they didn’t hold the plane and they just closed the doors. Had they even held it for two minutes I would’ve made it. She simply told me that the flight attendant on my flight lied about the plane being held, and that they do it all the time. These were all employees of the same company ITA. I was absolutely livid at her indifference and having been lied to and then having to wait five hours and waste a day in Europe at an airport.

The flight was canceled and we have not received the refund
