Airliner (3)
I believe the answer is:
jet
'airliner' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for jet that I've seen before include "Spurt; aircraft" , "Aeroplane" , "Glossy black colour" , "Black variety of lignite, used for ornaments" , "Rapid stream of liquid or gas" .)
