Goes public with (4)
I believe the answer is:
'goes public with' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for airs that I've seen before include "affectation of superiority" , "- - and graces" , "Tunes and affectations" , "Tunes and posturings" , "Arrogance" .)
