What are the potential pitfalls of using a random order for displaying cities in the airport schedule?

Potential pitfalls of using a random order for displaying cities in the airport schedule include confusion for travelers who are trying to find specific destinations, difficulty in locating information quickly, and inconsistency in the display which may lead to user frustration. To solve this issue, it is recommended to display the cities in alphabetical order to provide a more organized and user-friendly experience for travelers.

// Sample array of cities
$cities = ['New York', 'Los Angeles', 'Chicago', 'Miami', 'Dallas'];

// Sort the cities in alphabetical order
sort($cities);

// Display the cities in the airport schedule
foreach ($cities as $city) {
    echo $city . "<br>";
}
