Old article that you quote there.
About "his groups," the guy says he is a meeting planner. So, he organizes group travel. Furthermore, from his article, it seems he normally has means to give ample advance notice. So it's not like he is talking about getting an extra plane in service at the last minute, but about the sort of extra flights that can be planned for.
