The folks fly out to a friend in France (6)
I believe the answer is:
family
'the folks' is the definition.
(thesaurus)
'fly out to a friend in france' is the wordplay.
'out' indicates putting letters inside.
'to a friend in france' becomes 'ami' (I've seen this before).
'fly' placed around 'ami' is 'FAMILY'.
(Other definitions for family that I've seen before include "Household" , "Nearest and dearest" , "line" , "Closely related group" , "Means-tested benefit for working people with children, paid from 1971 to 1986" .)
