We had to take a bus to the plane and get on from the tarmack. Just leave enough time to get through that process too.
ElizabethFlew with Iberia-May 2025
Get to Rome airport a bit early. The lines for passport control can be long if you have a US passport. The signage can be confusing, but once you figure it out it is easy. Staff at Rome airport are very good and the lines were not bad there. Just security and passport control.

Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice

Legroom in Economy was fair to good. Seat was omay; I was hit in the shoulder twice by the cart as it was being whisked through the aisle. Overhead space was good for my carryon. Lighting environment was nice

Good experience. Staff was friendly and helpful. Flight was slightly delayed due to airport construction, but they still arrived on time.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

How can you rate a flight when it is canceled after you leave the gate & 3 hours into sitting there or in remote area of airport after mechanical problems

The international / itallian speakers did not seem as friendly and professional as the others. Drink selections were denied ( a beer) until questioned about lack of ANY beer on the plane and then four options were given.

Flight from Rome to SFO was excellent compared To our flight to Europe from SFO. The food was much tastier. You can see how UNITED is skimping, though. Instead of getting something mid flight you had to ask for it. It was not automatically served. There was a cookie at the end of the arrival meal, for example that tasted like it just came out of a box. They used to serve a little container of nuts, now … a tiny container of nuts, mixed with pretzels. This was business class that you really have to pay for! But this is minor complaints compared to the overall. My major complaint is the position of the even numbered seats by the windows. You have to turn around to see your window & the positioning as some other controls are harder to get at. This is compared to the odd number seat that are perfectly aligned.

This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!

Flight was On time and landed 30 mins early considering we were flying into Newark. No complaints.

Everything was great except for one thing. I was sitting in seat 1L with plenty of windows. Because we couldn’t sit next to each other, my husband was in 2L with only one window that he had to almost turnhis neck around to look out. Therefore, the window position with 1/2 of the “window” seats in business class is not optimal

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

We would fly ITA again. The planes had relatively comfortable seating. The crew was fine. The inflight entertainment was very good. The food was meh. But overall we got what we paid for.

I paid for extra Comfort Seats that turned out to be regular ones and have asked for a refund. The bathrooms were filthy the entertainment screen didn't work the Wi-Fi didn't work the food was mediocre at best and the seat I was in was terribly cramped especially when the person in front of me put their seat back. You couldn't even open the tray table. The staff was inattentive. I do not intend to take ITA ever again

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.

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

Flight bumpy and aircraft old with tape over seats , it seems there is a lack of maintenance, air pipe blow off in the middle of the flight, flight attendant seemed not to be worried about it. Food got very bad over time , not only for the quality but for the quantity . Seats are very uncomfortable , entertainment not working properly.

I was never able to use this flight. I booked my flight through KAYAK, using cheapfaresflights, and the agency did not book the ticket correctly. When I went to check in for my flight in Rome, my details had changed. My name was incorrect , and the itinerary was not what I had paid for. I was unable to board the flight and I had to purchase a second ticket at considerable expense. Unfortunately, no one at KAYAK or Cheapfaresflights was able to help me. They both shifted the blame on United Airlines, United Airlines was able to provide me a full detail that the error occurred on the travel agencies side. I consider this fraud and will pursue it further.

I never made it to Rome, therefore I never made it to the Lufthansa flight. Air Canada cancelled its flight out of Raleigh Durham, I missed the connecting flight out of Toronto and after other airline mishaps took place and I had to give up getting to Rome and dissappointing the friends and family waiting for e in Rome. I am currently trying to get reimbursed.

Crew could have been more helpful in helping to find location to store luggage in overhead bins in order to expedite seating. Seating was cramped and uncomfortable.. Other than that it was a standard flight.

The flight was delayed 7 hours and we were given 10 euros vouchers. This is ridiculous. The crew was not nice at all, they just did their job with serving food and drinks. Did not even apologize for the delay!!!!

Flight attendant was very rude helping me out. Food was discussing did not eat any of it.

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

The flight was cancelled due to tech problem with the plane

Got auestioned multiple times by gate agents. They ran out of chicken for the first meal. Slept pretty good on it and had good entertainment.

seats in economy are just uncomfortable due to the amount of space this, or any airline provides. Until the government sets minimum standards for comfort this will continue.
