Eggman,
I assume you mean ITU training?
If that's the case, sit down on a long layover, and start by looking at the training letter. Take a look at every guy junior to you, going to the same equipment. Look for the nicest 2 or 3 (or just catalogue all elegible VAC's). Once training is done (those guys jr activate) you can piggyback on any of them. My first year as CAP in the bus I ended up with a DEC slot. Of course, it was only that first year. (argh)
