When I was 20 I was arrested for under age drinking. Yeah...probably not the brightest of choices but now I want to apply for a regional. I was not convicted and did probation before judgement on the east coast. I had my record expunged from both the state and government. I have submitted my fingerprints to the FBI for a background check assuming that is the agency who the airlines go through for the TSA background checks. My fingerprints came back with no arrest record. Does this mean I am in the clear.

I would hate to get to groundschool only to find out something different.
Thanks,
