Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

An international flight on an apron is pretty unusual in my 40 years of traveling. Departure delay. Luggage despite over an hour connection did not make it to the flight. Actually still in Germany. My luggage was not moved until I reached my final destination despite knowing it to be left in Germany upon my arrival in Chicago. The service left me a little off, both going and returning from Europe. Light on in the cabin even during a night flight and lots of traffic no matter what. Maybe passengers want more service? As a frequent traveler i just want to be able to sleep, the food will be better at the destination anyway. So since the cabin crew woke me up I asked for a cocktail, I did not get the best response although sitting in row 20 premium economy. I usually fly premium economy or business and my 2 flight to Europe in 2025 with United both had luggage delays and other minor issues. American flights to Australia, Canada and Europe went smoothly and Premium plus feels very much like business light. Is United Club becoming a waste and Silver/Gold levels another waste??

This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

Not enough veg food available for passengers. I actually did not get the veg food and was told it was over, and I starved the entire flight duration.

The LH flight was great except for the delay at boarding. It should be announced well in tme.

Could have said yes to a glass of wine 🍷 instead of saying we'll come around in a couple of hours

Inoperable monitor left no entert for 9 hours. Crew was not helpful Food was awful.

The food and sitting need improvements. They were extremely bad.. If you choose to recline, there is no room for the passenger behind you. This is one of the worst sitting arrangements that I ever experience. The aircraft was not properly clean before boarding.

Had one staff that was not pleasant. Seems they are stressed with too many people to care for.

Ok. Get a different kosher caterer. The food was odd.

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 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.

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
