Business was very pleasant. Fantastic staff. This is the longest I’ve slept in business class going transatlantic in years!

Worst airline. Nine hours late. Checkin agent was not helpful at all.

Horrible. I was on flight AZ620 from Rome to LA. I paid over $4k for my business class seat and had a horrible experience. The WiFi was not connected for the entire flight and instead of being transparent with the passengers, the staff passed out WiFi vouchers and failed to let us know that the Wifi did not and would not work for the entire flight. Much worse is the terrible treatment from the manager of the flight attendant staff. I got up from my business class seat to use the restroom meant for this section. The flight attendant manager (I didn't catch her name but later learned she was the manager from another employee) started yelling at me that I couldn't use the restroom. I thought maybe it was busy. Then another flight attendant came to my seat and said that her manager thinks I'm not in business class, but I should let her know I am so I can use the restroom. I stood up again and before I reached the restroom, the manager was already yelling at me again to use the restroom in the back! She was judging me based solely on my appearance and assumed I wasn't business class. I had to interrupt her constant yelling to tell her "I am business class." She was racist and rude. I travel constantly for work, but moving forward I am never going to spend my money on an ITA airway flight again. Thanks to this manager, you lost a customer.

I am vegan, and the food was not what I expected it to be One meal was good, but the rest of the things were not very satisfying… I was disappointed in the food The flight itself was very smooth and everybody was very very nice… The boarding was very good

Crazy and confusing check in process for connecting international flights. Extremely uncomfortable seats in economy, bad in flight service with useless attendants, 10 year old movie selection, inedible food + only 1 full meal for 12+ hours long flight - 2nd snack was a cold bun with 1 slice of tomato and 1 slice of cucumber; 3rd was 2 breads - 1 hot and 1 cold. Finally absolute bad information on arrival time - in flight suggested we will reach at 12 AM until last minute, when we landed it was 1:15 PM

The price for Premium Economy seats very competitive and ITA beat the big guys in terms of fair. However, seat comfort was below expectations. Movie selection was poor. Food - absolutely horrible!! I felt like a prisoner for 13 hours being fed cold damp rolls and room temp water. NOT what I expected for Premium Economy!!

Most importantly, got us there and back safely and on time. Seats in Prem Econ spacious enough and comfortable. But pulldown footrest on both flights inadequate/broken. Crew...mixed: a few were quite pleasant, others seemed disinterested. Food was underwhelming. Yes, I know it's just "airplane food", so dont expect much... but even United is doing better now, and BA more so. Would I fly ITA again...perhaps. Price diff was main selector this time, almost 1K LESS/person than UA. I'm naturally frugal -- For 2K I'll put up with some small inconveniences.

Flight attendant really had bad behavior.. yelled at people when she is trying to defend, to have favor w her people..!

Top notch re cleanliness, comfort, operational. Attendants attentive, cheerful, courteous and professional. An unusually high-grade experience all around.

They are nice personal and as sky silver medaglia member love Delta air and partner
