Assuming you have picked two nodes and stored them in source_node and target_node, and you want to label everything in between with class 'path_element':

p = cy.elements().aStar({root: source_node, goal: target_node, directed: true}).path;
if (p) {
  p.filter(function(i,x) { return x != source_node && x != target_node; })
      .addClass('path_element');

  p.edgesWith(p)
      .addClass('path_element');
}
