Please pardon my ignorance, but I could never wrap my head around this one.
"c" availability indicates that the waitlist for that fare bucket is also closed as well as there being no space available.
Having C and L (waitlist open) is a holdover from the past and for compatibility with other airlines who are connected to global ticketing and distribution systems but may not for whatever reason provide numerical breakdowns of the availability of seats in each bucket.
