Benefits arising from realism when flying around Italy (3,5)
I believe the answer is:
air miles
'benefits' is the definition.
Although both the answer and definition are plural nouns, I don't understand how one could define the other.
'realism when flying around italy' is the wordplay.
'when flying' is an anagram indicator (letters fly around).
'around' indicates putting letters inside.
'italy' becomes 'i'.
'realism' with letters rearranged gives 'armiles'.
'armiles' going around 'i' is 'AIR MILES'.
'arising from' is the link.
Can you help me to learn more?
(Other definitions for air miles that I've seen before include "Fliers' accumulated points" , "award for being high-flier?" .)
