but I assume thats not what you really want ,but instead ,you want to use another port if you already have a webserver or other service on port 80
in that case
set a listen port in ports.conf like say port 8080
edit the virtual host in virtual-host.conf to be <VirtualHost *:8080>
edit the /etc/airtime/api_client.cfg port to 8080
edit the /etc/airtime/airtime.conf port to 8080
restart apache
you can now have both a Webserver on port 80 and your Airtime on 8080
Good Luck
