Another great report,
SFflyer123! Thank you again for a great video TR, as well.
This is petty, but I would have figured UA's spirit offerings in F would be a little better. That's basically the same list you would find on, say, AA domestic F. Interesting.
The new F / J layout in the 772 is also interesting - it's so close to the J cabin! I'm sure that was no bother whatsoever, as LH has the same layout with their F / J cabins on the A340's, etc. It just seemed very close on UA from your video.
Lastly, thank you for showing the LH Arrivals Lounge. Last time I went to FRA, I was debating the use of the Arrivals Lounge, or the Senator's Lounge. From your video, it seems the Arrivals Lounge does have a much better selection of food, and is a little quieter. I felt the Senator's Lounge was too similar to the regular Business Lounge. The Arrivals Lounge seems to be set apart from both.
