Hopefully you don't consider me as a killjoy:

STR-ZRH was HB-IXO
ZRH-BRU was HB-IPV

I signed 2 sickbags yesterday (but not the magazine, as it was the last day) on D-AVRM, but none today, as the plane was quite full and seatblocking did not work ex-ZRH.
And yes: 24 minutes isn't really a short flight. My shortest one was on an A330-200 (LX) in F: 12 minutes. It's a scheduled flight -> somebody guesses?
