I used to be regular SLF on a loco, usually with hold baggage (spares). Turn up, relax and make damn sure I was one of the last to check-in. Also made sure I was one of the last to board.
Generally, got a seat within the first 3/4 rows but wasn't particularly concerned as I've yet to see a baggage carousel beat me to it.
Last to check-in, last to load, first out, generally speaking. Put it this way, you've leveraged the odds in your favour.
I've never understood the mentality of the folk who stand-up as soon the plane stops, it ain't musical chairs, ain't nothing gonna disappear if you're not off the plane in 3 minutes!
