I fly FRA-VLC-FRA route in J occasionally, and it is as others describe (with cold meal). In general I'm quite fine with the service, although I do wish that there would be a separate FRA airport bus for J passengers for boarding at a remote stand, and the VLC flight often seems to be parked at a remote stand. If you're flying back to FRA on LH from VLC, FYI at VLC, they sometimes don't really separate the priority boarding well, but there are very few priority passengers and you just have to approach the agent and they'll let you through. Sometimes they will recognize you from the check-in desk as they're often the same agents, and they'll proactively wave you up.

Here's what the cold meal looks like. This is lunch VLC-FRA in December. Rest of the flight report here on my blog.

Here's a breakfast picture VLC-FRA from August. Rest of the flight report here on my blog.


And a couple years ago I took the evening flight FRA-VLC - but you can see the setup is basically the same as my more recent lunch flight. Though after this meal, which already included a dessert and chocolates, they handed out ice cream bars! So many desserts Maybe because it was summertime? (Here's the flight report on my blog)



FRA-MAD is just slightly longer than FRA-VLC, just putting it over the threshold for hot meal service I believe. I learned this when my sister flew FRA-MAD in Y, and was surprised to find out that she was served a hot meal! On FRA-VLC in Y it is always just a sandwich, pastry, or yogurt.
