Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

Boarding was weird. They boarded two flights at the same gate at the same time. So mass confusion for the non English/French speakers. So many people at such a small gate. Like every other part of this airport you have to walk miles between everything. Gate to plane was a 5 min walk :) several long flights so I was worried about my steps but ended up walking several miles here so worked out.

This review is based on 2 things: 1. The lack of hygiene on the plane. 2. William - the head flight attendant. The lack of cleanliness on the plane upon arrival was appalling. Being given a sanitizing wipe upon boarding of the plane is shocking when you consider the cost of a business class flight. UA expects me to do their job and clean all the bread, food and debris left from previous guests. Does this sound normal to you. The seat, the food table and the sides were full of crumbs, chocolate and dirt. When I told the flight attendant they just gave me more wipes so I could clean it myself. Secondly, William the business cabin head flight attendant was so busy flirting with a couple in the front that his attention to the other guests was minimal. He continuously asked them if they were ok or if they needed anything and it didn’t matter if the rest of us needed anything. And if you are the lead attendant shouldn’t you be checking if the bathrooms in business class are clean and needing toilet paper. There were 2 bathrooms in business. Halfway through the flight the first bathroom was closed and the second bathroom was dirty and had no toilet paper one hour and a half before the flight landed. He needs additional training on prioritizing things. He should care less about flirting and more about his work

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

Courtesy of waitress. Could improve on time management and check-in

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.

The flight leaving mxp was late I lost connection in ORD Changing flight was hectic and messy, overnight and meals vouchers very poor

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.

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

Kayak was an utter disaster. They booked the tickets through a 3rd party and the 3rd party changed the dates of the flight without checking with us. They promised to change it back, but they never did, and I eventually had to dispute the credit card charge to get my money back and had to reserve through another website. NEVER use KAYAK again!

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 crew was business like and not very friendly. It was very disappointing in that they handed out the meal at the beginning of our journey. Eight hours later, they handed a sandwich and a drink. During their eight hour break all they did was sit in the back, looked at their phone and read. They never came down the aisle during those eight hours and offered another beverage or to See if there was anything they could do for the passengers.

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.

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

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
