Publicises cruise, possibly landing here? (8)
I believe the answer is:
airstrip
'possibly landing here?' is the definition.
(where planes might land)
'publicises cruise' is the wordplay.
'publicises' becomes 'airs' ('air' can be a synonym of 'publicise').
'cruise' becomes 'trip' (I've seen this in another clue).
'airs'+'trip'='AIRSTRIP'
(Other definitions for airstrip that I've seen before include "Small flying field" , "Simple runway" , "Temporary runway" , "Land here" , "Small runway" .)
