Aerial transport suggested for the prairies (6)
I believe the answer is:
plains
'prairies' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for plains that I've seen before include "Flats" , "Grasslands" , "Large areas of flat lands" , "Flat tracts of land" , "Spinal (anag.)" .)
