I believe the answer is:
beeline
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">direct route</span>' is the definition.<br/ ><span class="explanation-format__explanation">(direct route between two points)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for beeline that I've seen before include "Undeviating route" , "Shortest route between A and B" , "Make ........ for - go straight towards like honey collector" , "Most direct route" , "Straight route" .)
