Often in physical science courses, we define the Earth system as the lithosphere (rocks), atmosphere (air), biosphere (life), and hydrosphere (water) [also sometimes separately defining a 5th aspect, the cryosphere, which is ice]

In the end, we often just think of the Earth as everything confined by its gravity (not including in orbit) as that's everything still controlled by the Earth.

But in a very true sense, you're still leaving the Earth when you take off on a plane.
Just you're still in a state/region of the Earth's system where what goes up must come down. So you won't be gone long!
