Flying in J I noticed a paper with all the J's seats charts filled with pax's last names (my children they put in first names.) Also I noticed some seats have letters that designated their status. DM, GO, EM (emerald), SP (Sapphire), etc. Only the DMs are emphasized with a circle. Now, there is one that interests me but I can't figure out what it stands for: KSM. What is KSM?
