Can I get on a plane from Boise to spokane with just my prison Id if I just got released and I already have a prepaid ticket waiting?

Your prison ID is State issued so it should not be a problem.

I am sure you're able to get to your destination as long as you have your ID so it shouldn't be a problem.

I'm not sure. But if you have your prison ID and a prepaid plane ticket you should be good to go but try finding more information online and the rules/regulations.
