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.

Lost luggage, they need a baggage service representative available all times in Atlanta
