There is at least one object with null origin. You can do a simple check before appending the info to the list:

$ (document).ready (function(){
    $.getJSON("/common/v1/airport.json?code=bgw", function(data){

    $.each(data.result.response.airport.pluginData.schedule.arrivals.data, function(){

      if (this.flight.airport.origin) {
        $("ul").append("<li>"+this.flight.airport.origin.position.region.city+"</li>");
      }

    });

    });

});
