Not great - seats were very narrow and food was terrible.

Not great - seats were very narrow and food was terrible.

Some of the crew was sassy and not super helpful. The food was okay, but it seems like they were all unprepared compared to my flight I did from JFK to Frankfurt

We missed our flight. There was not enough time built into the layover to get through immigration, customs, bagclaim, bag rechecking, and the long trip to another terminal and gate. Kayak really screwed up. We took the bus up to Wisconsin and then were picked up in Brookfield by private car. It was lucky we didnt miss the last bus out.

We were in premium economy seats that appeared to be locked in plae, No reclining. My aching back.

I don’t understand how they charge as much as they do for such a poor experience

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

I wish the plane had pod seating for business class. I had a window seat (8K) and I had to climb over the person sitting on the aisle when I needed to get up. Also there is no partition between the seats for privacy when sleeping. The Asian airlines have much nicer business class seating. Their seats are wider for better comfort when sleeping.

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

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
