Being transported to the air terminal is suitable (4)
I believe the answer is:
rapt
'being transported' is the definition.
(both can mean enchanted or fascinated)
'the air terminal is suitable' is the wordplay.
'terminal' says to take the final letters (the final or terminal letter).
'is suitable' becomes 'apt' (apt means appropriate or fitting).
The last letter of 'air' is 'r'.
'r'+'apt'='RAPT'
'to' is the link.
(Other definitions for rapt that I've seen before include "Engrossed, spellbound" , "carried away" , "Very attentive" , "Fully engaged" , "Held spellbound" .)
