Airline reviews

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

Booked seats (paid extra) online and found they didn’t exist on the flight. We were then separated from the rest of our party. Given seats in the very back of the plane. We will not fly Discover or Lufthansa again. We will not book flights or travel through Kayak again!

Had a few open seats and could use it for a great rest ful journey

It was very good. Service was friendly and efficient, and food was good.

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

Crew was outstanding, helpful and friendly. Food is deteriorating. The snack at the end of the flight was not good, a greasy moosh of toast cheese snd other unidentifiable ingredients. Coming from Germany a pretzl with butter would have been better. Entertainment had a great selection.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

Awful cold sandwich, pizza was bad and coffee was extremely cold I expected better quality in wines on the way to Rome I order red wine and could not drink it ! Bad quality of wine . Being an European airline’s wine are inexpensive so could have better selección of wines . So on the way back a settle for water with is a pity . The crew disappear and didn’t pick up the trays after meals or the garbage of the snacks . Iberia has better service and other airlines

The toilets are very small for a long trip like this. There is no space whatsoever. Totally unusable,

This airplane is much better. Not worn out like the one we flew with fr NY to Rome. Flight attendants were ok.

Poor. The airlines left my luggage in Miami. It took 2 1/2 days to get my luggage at my destination. I was forced to buy clothes and daily items for days. There was little concern to get my bag to me which highly impacted my trip. Seats were cramped as well. Would not recommend this airline to anyone.

This was our return flight. It was slightly better than the one we took to go to Rome, mainly because the food was slightly better and more abondant. On our LA-Fco flight the food was way below average. Also, it felt like the legroom in Economy was smaller than other airlines we used in the past - my knees were touching the seat in front of me.

There was so little leg space in middle seat that the blanket/pillow accessories and my feet could not fit. Knees were 1 inch from seat in front and when person in front reclined, it was uncomfortably invasive in my space. I am not large, 5’5” and 130 pounds

Wonderful! Everyone very helpful and kind. Returning flight was cancelled but rebooking was easy.

The seats are very tight and uncomfortable. The recline position did not work.

Flight was on time, there were no issues. It was also direct to SFO. For an international flight, I call that a win.

Flight was on time and pretty standard. No Hiccups. I have no complaints, which is a lot to say about a 12 hour flight.
