It really depends upon which state your License(s) are/have been in. For example, FL keeps records for life, whereas IL only goes back 3 years, then they toss everything (except serious stuff like DUI's, or anything carying a criminal charge). If you are in a state like IL, if you don't want to tell them about, they can't find out beyond 3 years. Anyway, most airlines only pull your stuff from the National Driver Register, which usually only carries serious offenses such as DUI, vehicular homicide, etc. Hope that helps.
