I was also there in FRA during the Frankfurt auto show, so I decided to make my lay-over into 10 hours instead of the usual 2-3 hours, so I could go see the show. It was very nice. I only had time for one exhibit since this place is massive, and I had to see the new Mercedes Benz S class. It is a car that apparently can drive itself. You will be able to see the video of the exhibit in my video:

For those who prefer the photos, they are here below:
I start off at SFO, and they make us use the United lounge, since there is no LH lounge here. Of course, the carrot sticks and crackers are still here:

After the lounge, I get on board on the upper deck. Unfortunately, I don’t have photos of the boarding, but you can see the boarding process in the video, which shows how they do upper deck & lower deck boarding. I settle nicely for a glass of champagne:

After take off, LH serves nuts from a package. They aren’t warm, but they are quite tasty. I have a glass of red wine also.

Afterwards, I prepare to have chicken appetizer. It was very good.

I then have the chicken entrée (yes, lots of chicken). It was very very tasty. I enjoyed it quite a bit.

Dessert was fairly standard with ice cream and the chocolate was quite good also. But it was probably too much in terms of the sweets. I think one or the other would have been fine.

I was not able to sleep much, so I watched movies. The flight is very nice, but it’s really a shame that they have the angled lie-flats in their “flagship” A380. The business class product would have been so much better with a true lie-flat. I know that it wasn’t out when the A380 was around, but LH should have just waited. It’s unfortunate.
After a short nap, I was able to have breakfast. They served cold cuts and some eggs. This was totally fine, and very tasty. I was happy with it.
After the landing, I then went to the FRA arrivals lounge, which is a real nice perk when arriving at the airport. They have showers there also, good food, and wi-fi. I then went off to the auto show and checked it out. For details of that, please see my commercial-free video:
