CPL's are typically granted at the state level, but not all states need to recognize your CPL as valid. So it's perfectly legal for me to fly from Detroit to New York with a firearm, because the TSA staff in Detroit, MI legally recognize my MI CPL. However, the TSA agents in NY do not recognize my MI CPL. As a result when I fly back from NY to MI, I could get arrested for carrying a firearm.
