Publicise new tramline for transport interchange (3,8)

Ross

I believe the answer is:

air terminal

I'm a little stuck... Click here to teach me more about this clue!

'transport interchange' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'publicise new tramline' is the wordplay.
'publicise' becomes 'air' (airing is a kind of publicising).
'new' is an anagram indicator.
'tramline' is an anagram of 'terminal'.
'air'+'terminal'='AIR TERMINAL'

'for' is the link.

Can you help me to learn more?

(Other definitions for air terminal that I've seen before include "part of Heathrow" , "place to start journey" .)
