Look left on plane for its destination (7)
I believe the answer is:
airport
'plane for its destination' is the definition.
I can't judge whether this definition defines the answer.
'look left on' is the wordplay.
'look' becomes 'air' (something might have a certain air or look).
'left' becomes 'port' (left side of a ship - opposite of starboard).
'on' means one lot of letters go next to another.
'air'+'port'='AIRPORT'
Can you help me to learn more?
(Other definitions for airport that I've seen before include "Transport hub" , "Heathrow, for example" , "Aviation complex" , "See 18" , "Pair rot badly in the transport terminal" .)
