Not wishing to hijack the thread, but I have a somewhat similar question. In our case the flights in question are rather longer. We are booked in BIZ on LH856 from FRA to KEF. We are also returning on LH857.
Given that these flights are, respectively, 3h40m and 3h30m in length, can we expect a hot meal, or will it still be a cold offering? I am aware of what European BIZ is like with such airlines as AF and BA, but have not taken a BIZ flight of this length on LH for some time.
I'd also be very grateful for any information on any other aspects of these flights.
