Depends on the airline and how the data was put into The database checked. I had a buddy get tagged for something which was dismissed. He disclosed it during his recruitment process and kept the paperwork. In indoc he was pulled in for termination because the background check the original charge showed but not that it was adjudicated with a dismissal. He brought the paperwork in from the court and a printed copy of his airline apps showing it was disclosed to the company. He stayed.

Just disclose everything. If you haven’t yet, get copies of your court records to backup what you disclose.
