Unaccompanied Minors - Captain?
Guess it depends on Company Policy
Basic - 5 year disclosure
Standard - All convictions
Enhanced - as above plus any in the court system
If you are working with children and vulnerable adults
you are often required now to have an 'enhanced' check
Unaccompanied minors are in your charge as a captain of an aircraft so it may be that the Enhanced check is performed by some airlines....?
