1) Use sneak or a smoke bomb
2) Click on a ship terminal
3) Click on the planet you want to travel to.
4) You will be transported to the new planet still cloaked.

This works with Jedi cloak too, but is a bit more pointless given it has a timer on it.

Hardly an exploit...

the real one is talking to the ticket droid, then cloaking before choosing your ticket.

hehe yah, I do that with my Jedi to make sure i dont get ganked on the other end.
