Air cargo from Poland: ale, surprisingly (9)
I believe the answer is:
'air cargo' is the definition.
(cargo carried by a plane)
'poland ale surprisingly' is the wordplay.
'surprisingly' indicates an anagram (a surprising ordering of the letters).
'polandale' is an anagram of 'PLANELOAD'.
'from' acts as a link.
(Another definition for planeload that I've seen is " A crate-full".)
