Wait until you are done with your systems and get in the sim. Even when you are in the sim it is easier to observe sim lessons than it is to observe revenue flights. If you really want to jumpseat in training i would reccomend showing up in uniform with everything in line. (passport, certificates, and your CASS approval) Until you are done with systems i would concentrate on ground school stuff. Even until you are done with your PC i would only observe sims. Once you are done with sim training would be a better time to actually jumpseat.

and once you are verified with the pass bereau you can non rev anywhere you want to, they want you to stick around and concentrate on studying but you can go home as long as you get back
