var fromTitle = 'Paris';

// Note: if id is same and title is updated then it won't change, so set a new id if you are updating a label and then set it back
var fromId 	  = 'New York';
var toId 	  = 'new-york-city_ny_us';

var newFromOption = new Option(fromTitle, fromId, false, false);
$('.fromLocation').eq(0).append(newFromOption);   	// add the option because of AJAX it would not exist
$('.fromLocation').eq(0).val(fromId);             	// Select the option with the value
$('.fromLocation').eq(0).trigger('change');       	// Notify any JS components that the value changed

var newToOption = new Option(toTitle, toId, false, false);
$('.toLocation').eq(0).append(newToOption);   		// add the option because of AJAX it would not exist
$('.toLocation').eq(0).val([toId]);           		// Select the option with the value
$('.toLocation').eq(0).trigger('change');     		// Notify any JS components that the value changed
