Got another one from a colleague (not posting because it's not mine) - it looks almost the same as my 3rd one, but it has "FBAG" where the TK one has "FASTR". He didn't do anything special with baggage, we couldn't come up with anything we could tie to it. (Particularly he doesn't have any status currently, so it can't be priority baggage handling. It was a single leg trip, no SCON, no transfering, ...)
