Six have an airing perhaps in America (8)
I believe the answer is:
virginia
'in america' is the definition.
(state of America)
'six have an airing perhaps' is the wordplay.
'six' becomes 'VI' (Roman numerals).
'have' says to put letters next to each other.
'perhaps' indicates anagramming the letters.
'airing' anagrammed gives 'rginia'.
'vi'+'rginia'='VIRGINIA'
(Other definitions for virginia that I've seen before include "US state named in honour of Elizabeth I" , "Girl" , "One of the 13 original US states" , "Woolf and Wade" , "US East coast state" .)
