"Actually it is because airplane wings deflect particles of the air in a downward motion. For every action there is an equal and opposite reaction."

Well, that blows my theory of the wings creating a low pressure bubble that creates lift...

I used to believe that too. But winged-flight comes from air displacement, not because of the Bernoulli effect on a shaped wing. This is e.g. why planes can fly upside down.

Somewhat. But remember, vacuums do not suck. In order for a force to be created on the wing by the gas molecules, a change in the momentum of the gas molecules is required. The wing creates a pressure difference and that 'pressure difference' model is still taught.
