When it hits the air, it has some sort of chemical reaction that makes it sticky...

Superglue only works if there is some water present. Water vapour in air is enough to cause it to set.
AMAZING ACT - superglue dries quicker in water than in air and was originally designed to seal wounds on the battlefield until a medic could treat it properly! That's why it sticks so well to fingers!

By that question I take it you mean the inside of the tube and not the outside. I think I know why. All the while the cap or lid is kept on the glue remains soft and liquidy. If I was to leave the cap off the air would get to it and the glue would solidify. It's the same with liquid cement.

There's not enough moisture in the air inside the tube for it to react and stick.

Superglue (methyl isocyanate) is a liquid until it meets air (and moisture). Then it sets rapidly. In the tube no air, no water... so it does not harden.

Because its the introduction of air that begins the sticking process!

The glue needs air to activate it

It is activated by air,(it's not sticky until exposed)which is why the nozzle always gets blocked with hard glue.
