The SolutionUse keywords to disperse information
Set up keywords parents and children can text to airport security if they become separated. These keywords can provide them with steps to take and where to go to get help.
You should register keywords for lost children and parents of lost children. IMLOST and HELPLOST are examples of what you could use.
Configure IMLOST to send information about how a child can find security and the secret password to use. Configure HELPLOST to send information about what parents can do when their child is lost including the location of the meeting place.
Train your security team on how to respond to email or SMS based lost requests. Also, make sure they always know what the safe word is for lost children.
Post clearly visible advertisements and notices around the airport to let travelers know of the new initiative.
