Set out to fight with Dutch flight attendant (7)
I believe the answer is:
steward
'flight attendant' is the definition.
('steward' can be a synonym of 'flight attendant')
'set out to fight with dutch' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'to fight' becomes 'war' (warring is a kind of fighting**).
'with' means one lot of letters go next to another.
'dutch' becomes 'd' (common abbreviation).
'set' is an anagram of 'ste'.
'ste'+'war'+'d'='STEWARD'
(Other definitions for steward that I've seen before include "Official at function" , "Airline cabin worker" , "Official at event" , "Ship's officer" , "Waiter; estate manager" .)
