"I'm surprised that US based cargo carriers will not allow this"
Amos, this is not allowed courtesy of Uncle Sam (an American metaphor for the US Government) thru it's certification (op spec's) sponsorship. This is because you never know when your accompanied 8 year old son will suddenly grow teeth and attempt to takeover your aircraft (even though horse handlers, curriers and such are ok to ride).
That being said Amos, perhaps you are a foreign commie spy or alquada operative posing as a ppruner to gain terrorist aircraft access information with this sensitive topic. - If so, then my local FBI office would like to know
