I'm actually kind of confused on this too. I chose the government issued plane ticket. I wasn't billed anything, and I got my flight itinerary through email. On the email, it says that the ticket costs $500 or something, but it seems as though it's already paid. (since my flight is booked)
....so does this mean that the travel arrangement payments taken care of?
that's my question. that's what I'm trying to figure out.
