To change the default trip code that is generated by the plugin you can use the  filter given below:

wp_travel_trip_code

To execute this you need to activate the child theme. You can create the child theme manually or simply create the child theme using the plugin given below:

WP Child Theme Generator

After activating the child theme in your child theme functions.php add the below-given code.

add_action( 'init', function() {
   function wp_travel_child_change_trip_code( $code, $trip_id ) {
        return 'YOUR TRIP CODE  ' . $trip_id;
   }
   add_filter( 'wp_travel_trip_code','wp_travel_child_change_trip_code', 10, 2);
} );

Here replace ‘YOUR TRIP CODE” with your trip code. Each trip will have the unique id behind it but will have the same code that you enter here.

After adding filter code:

Note: This filter code can only be used with WP Travel free plugin.

If you WP Travel Pro user then you can change the trip code manually, through the admin dashboard by going through Admin Panel > Trips > All Trips > Individual Trips > Trip Options > Itinerary > Trip code.
