Bristol Airport has worked with OCS Group, the special assistance provider at the Airport, and local Dementia, Autism and Alzheimer charities in developing a hidden disabilities assistance card in addition to the lanyard scheme. The card, which is the size of a business card, acts as a discreet sign to airport staff to identify passengers who may need additional support or assistance as they travel through the airport. The card can be handed discreetly to airport staff along with the passenger’s boarding pass or passport.
