Flier has a minute to infiltrate Asian land (6)
I believe the answer is:
airman
'flier' is the definition.
(I know that flier can be written as airman)
'a minute to infiltrate asian land' is the wordplay.
'minute' becomes 'm' (abbreviation).
'to infiltrate' is an insertion indicator.
'asian land' becomes 'iran' (country in Asia).
'm' inserted within 'iran' is 'irman'.
'a'+'irman'='AIRMAN'
'has' is the link.
(Other definitions for airman that I've seen before include "He flies" , "crew member" , "Pilot" , "Aviator" , "Marina (anag)" .)
