To ensure that cities appear in a specific, predetermined order in the airport schedule, a beginner in PHP can create an array of cities in the desired order and then loop through this array when displaying the schedule. By iterating through the array, the cities will be displayed in the specified order. 

$cities = array("New York", "Los Angeles", "Chicago", "Miami");

foreach ($cities as $city) {
    echo $city . "<br>";
}
