Flight late but they were nice and food is pretty decent. The seats could use updating.

ITA does not allow free seat selection even in business class, if you don't want to pay extra for the seat they assign it to you during check in. For me it was seat #8 in both ways. It's last seat in business class with smaller space, close to kitchen, toilets and closets for supplies. WiFi didn't work at all. ITA is lower coaster, better to buy premium economy in regular company (AirFrance, Delta, Lufthansa, United, etc) than business in ITA Airways. ITA - never again

The flight attendants weren’t friendly. They gave us yucky food.

No complaints. Everything was fine. Very glad I was in premium economy

Overall flight was fine as was price. FCO leaves a lot to be desired. Not enough agents to check people in quickly, confusing security location and extremely, ridiculously long lines to get through multiple security checks. It was the least to say it was a hot sticky nightmare. Dulles is not better although arrival was fine, traffic to the arrival area was a nightmare where I finally gave up, parked the rental and met my wife with the luggage in the parking lot. I will avoid Dulles in the future.

Crew was very friendly and accommodating. Main enter was good but snack could be better. Perhaps adding fruit would be an excellent option.

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

The flying experience is excellent. The seats are very comfortable and spacious. The staff is professional, attractive and efficient. The ITA business class lounge in Rome is poor. There are no comfortable seats for long layovers. It’s too crowded. The showers are too few and the towels are of extremely poor quality.

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
