I believe the answer is:

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">broadcasting now</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for on air that I've seen before include "Radio show might be" , "very happily?" , "Cushioned" , "now showing" , "with audience?" .)
