This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

Very comfortable plane. The food was very good (for airplane food). The crew was great

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.

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.

Sitting at Logan on the taxiway for 90 mins waiting for a gate after an 8 hour flight is unacceptable. Logan and delta need to do better

The flight was long and offered very little comfort. The seats were exceptionally small and quite uncomfortable, making it difficult to rest on a long journey. The onboard meals were below expectations, although the cabin crew was excellent throughout the flight—professional, attentive, and courteous. I understand the commercial pressures airlines face, but maximizing capacity by reducing seat size and comfort has become an industry-wide concern. While many travelers will continue to tolerate these conditions out of necessity, an increasing number of passengers will choose alternative airlines whenever possible in search of a more comfortable travel experience. Investing in passenger comfort is not only appreciated—it is also an important factor in long-term customer loyalty.

Worst airline. Nine hours late. Checkin agent was not helpful at all.

One bathroom wasn’t working and the other bathroom faucet wasn’t working.

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!

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
