On that date, a Real ID compliant driver's license or ID card will be necessary to board commercial aircraft in the United States. Maryland residents can check their Real ID compliance using the Real ID Lookup Tool provided by Maryland Motor Vehicle Administration (MDOT MVA). 

The MDOT MVA team is frequently on-site at BWI Marshall Airport to assist passengers with Real ID questions. To see when the MDOT MVA team will be at the airport, please visit this page of the MDOT MVA website.
