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.

What occurred during this flight was far beyond an ordinary inconvenience or dissatisfaction with the onboard service. There were multiple failures involving the aircraft’s passenger-seat systems, the ability to summon cabin crew, sanitation, cabin crew responsiveness, food and beverage service, and the overall standard of passenger care. The circumstances were particularly serious because I am diabetic, and during the flight I experienced a situation in which I needed assistance while essential passenger-control functions at our seats were not working. I am requesting that ITA Airways treat this as a formal complaint requiring individual investigation, rather than responding with a generic customer-service apology. 1. All three seats had significant equipment failures Seat 46F: The entertainment screen was completely non-functional for the entire flight. Seats 46G and 46H: The screens themselves displayed content, but the following controls did not function: Cabin-light control Flight-attendant call button Flight-tracker button These were not merely entertainment-system failures. The malfunctioning controls affected our ability to control the lighting at our seats and, more importantly, our ability to summon a flight attendant when assistance was required. I specifically request that ITA investigate the maintenance records for the aircraft and these specific seats and determine whether these defects were known before departure, reported during the flight, or documented by the cabin crew. 2. The defective equipment directly affected my ability to manage my diabetes I am diabetic and require insulin. Because the cabin-light controls at our seats were not functioning, I was unable to properly illuminate my seating area when I needed to administer my insulin during the flight. More seriously, when my blood sugar became low, I was unable to use the attendant-call button to request assistance because the button was not functioning. This transformed what might ordinarily be considered an entertainment-system problem into a much more serious passenger-care issue. I was on a long transatlantic flight, unable to properly illuminate my seating area when necessary and unable to summon a member of the cabin crew through the designated call system. 3. My daughter repeatedly attempted to obtain assistance when my blood sugar was low When my blood sugar became low, I needed juice or another rapidly available source of carbohydrate. Because I could not use the attendant-call button, I sent my daughter to ask the cabin crew for juice. She made multiple attempts to obtain assistance. Despite these repeated attempts, the cabin crew did not appropriately respond to her request. After multiple attempts from my daughter, the curtain was closed. I ultimately had to obtain candy from passengers seated nearby because I could not obtain the assistance I was seeking from the cabin crew. I consider this one of the most serious incidents on the flight. I am not suggesting that cabin crew were required to provide medical treatment. However, when a passenger is seeking assistance because of low blood sugar—particularly when that passenger’s designated call button is not functioning—I believe a reasonable standard of passenger care requires the request to be acknowledged and handled appropriately. I therefore request that ITA investigate this incident specifically, including: Which crew members were assigned to our cabin/section; Whether any crew member observed my daughter requesting assistance; Whether any crew report was made concerning this incident; Whether the crew knew that the attendant-call buttons at our seats were not functioning; and What ITA’s procedures require when a passenger reports that they are experiencing low blood sugar or otherwise needs assistance. 4. The circumstances caused significant distress and interfered with my ability to manage my condition.The combination of the defective lighting controls, inability to use the attendant-call system, and failure to obtain timely assistance caused me significant distress.I was particularly distressed because I was unable to properly manage my medical needs in the manner I normally would during a long flight. My blood sugar subsequently remained elevated for an extended period. I believe the prolonged stress and circumstances surrounding this incident contributed to the difficulty I experienced managing my blood sugar during the flight. I am documenting this because I do not want ITA to reduce this complaint to a complaint about an entertainment screen. The equipment failures directly affected my ability to manage my medical needs and obtain assistance. 5. Unacceptable restroom conditions. One restroom was completely out of service for the entire flight.The remaining restrooms were extremely dirty with visible urine stains and no toilet paper. 6. Unprofessional and dismissive cabin crew behavior. Throughout the flight, the attendants were unpleasant and appeared irritated

The cleanliness of the Business class continues to disappoint. There was food on the floor when I boarded.

My son was served a muffin which had broken pieces of glass in it. Thank god he didnt swallow them and spit them out. i did let the crew member know and took pictures but nothing they could do. This could have been a very dangerous situation.

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
