Spot company getting into Israeli airline's return (6)
I believe the answer is:
locale
'spot' is the definition.
(spot can mean a location)
'company getting into israeli airline's return' is the wordplay.
'company' becomes 'co' (abbreviation).
'getting into' indicates putting letters inside.
'israeli airline' becomes 'el al' (I've seen this before).
'return' shows that the letters should be reversed in order.
'co' placed within 'elal' is 'elacol'.
'elacol' in reverse letter order is 'LOCALE'.
(Other definitions for locale that I've seen before include "Area connected with event" , "where something happens" , "Spot" , "Setting" , "Venue" .)
