ITA changed our 9 hr direct flight without giving any reason to 4 stop overs 24 hrs flight without delays.

Poor food choices for AVML. Totally out of the world food. Bad food menu.

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

Appreciated being met with a glass of sparkling wine - also the warm cleansing towel offered before the meal. The food was tasty!

First, ITA lost my bag and the baggage team showed no regard in trying to find it. Second, I had paid for priority boarding as part of a first class ticket and instead they disregarded boarding groups and we all boarded at the same time. Third, wasn't allowed to select my seat in advance even with a first class ticket. When I was assigned bulkhead, I was told I would need to pay to change my seat. Overall, very disappointing experience.

Inside plane needs to be updated, the lady sitting behind me was saying the frame from the window fell on her lap right before taking off and seats are very uncomfortable, cushioning is need of repair ASAP.

I did not leave to Italy yet. We had technical problems on flight from SF to Maimi and had to land in Denver and wait for another plane to take us to Miami, so I missed my plane to Italy. I am still waiting for the Agency to fix my flight till today the haven’t done anything and I am paying for my Hotel stay. Everyday they are promising to fix my flight, they are not doing so and they are not even looking for another solution

Overbooked. They left a lot of passengers on the ground

Need better food options. Need warm food both times Stevie was provided. Bathrooms are too small. For an international flights, seats are small and leg room isn’t enough. And for an international flight, serving spirits should be included, not just Italian beer and cheap wine. All the tv/film entertainment is quite old and not updated, but the size of the screen was good.

my flight from Rome to Boston was on a very old plane. My video and audio did not work.
