check the FAQ, there is some good info in there.

But as a 2P or 1P, using miles or e500's, you'll be on the PB waitlist. (And if using e500's you'll be "pending" until your window). 1K's go on the PA waitlist; if you use an SWU or a CR-1, you'll also be on the PA list.

About the best you can do is get on the list ASAP... if well in advance of the flight, use miles (or similar) as if they open up NC/NF space you'll be able to take advantage of it. Otherwise things will have to wait until your window opens. Tougher then.
