Syed Adam Ahmed's mother contacted by dozens of families with similar stories

It turns out the little Ontario boy who's been having trouble boarding airplanes is far from alone.

• Mother encouraged by government response to son on no-fly list
• Markham, Ont., boy, 6, on no-fly list, parents say
• Extra security screening not needed for kids under 18,Goodale says

The whirlwind of publicity about six-year-old Syed Adam Ahmed's difficulty at the airport has prompted dozens of other families with similar stories to contact Khadija Cajee, the boy's mother.

Twenty-one of them agreed to be mentioned in a letter that Cajee has sent to federal cabinet ministers involved in the high-profile issue.

Public Safety Minister Ralph Goodale promised to investigate after Adam's father, Sulemaan Ahmed, tweeted a photo from Toronto's international airport that appeared to show the boy's name with a "DHP" or "deemed high profile" label and instructions on how to proceed before allowing the youngster to check in.

They were trying to board an Air Canada flight Dec. 31, 2015, to Boston to see the NHL Winter Classic.

Tales of other children with the same sorts of travel challenges soon emerged. And now Adam's mother has become an unofficial liaison with the Liberal government on behalf of many families.
