Changed planes at Nice (8)
I believe the answer is:
pleasant
'nice' is the definition.
(associated in meaning)
'changed planes at' is the wordplay.
'changed' indicates anagramming the letters.
'planes'+'at'='planesat'
'planesat' anagrammed gives 'PLEASANT'.
(Other definitions for pleasant that I've seen before include "Refreshing" , "Enjoyable, agreeable" , "sweet?" , "Nice, satisfying" , "Charming" .)
