No it does not cure in air.

Superglue is an anerobic adhesive and cures when air is removed by
fitting the two parts together.

Bob, it's always puzzled me why it doesn't set in the tube / bottle as
they are sealed from the air

It does set in the tube. At least after opening.

Did nobody think to google it? From Wikipedia:
"Because the presence of ****moisture**** causes the glue to set, exposure to normal levels of ****humidity in the air**** causes a thin skin to start to form within seconds,"
