I'm planning to use ID 90 for the first time. Im just a little confuse on what to do. When I visit the TRIPS site, it is written on subload tkt "CAT A ticket must be listed/revalidated for the flight you intend to travel on prior to check-in". Can someone tell me what this means?? And when I issue the ticket, am I going to receive the tkt on my email or do i have to go to HQ to get it?? Sorry, Im a newbie regarding this matter. Hope you guys can help me
