Are you sure, you want to map away 'J' and 'K'? If so, you might want to
use J and K directly. It is certainly cleaner and I am not exactly
certain, that <s-j> will work. In any case, you might want to read at
:h J and :h K to see, what you map away.

No, airline is a statusline. That is no buffer. You are simply
decreasing the window size and therefore increasing the command line
(e.g. where you enter ':' ex commands)

Use an expression mapping, e.g. something like this
nnoremap <expr> <c-w>j winnr('$')>1?'<c-w>-':''

This maps Ctrl-W j to decrease the window size, only if there are
several windows open, else do nothing.

See
:h :map-<expr>
:h winnr()
:h expr1
