Added volume in disrupted arterial transport mode (3,6)

I believe the answer is:

air travel

'transport mode' is the definition.

'added volume in disrupted arterial' is the wordplay.
I cannot quite see how this works, but
'volume' could be 'v' and 'v' is present in the answer.
an anagram of 'arterial' is 'airtrael' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...

(Another definition for air travel that I've seen is " trips up?".)

I've seen this clue in The Guardian.
