No,you not understand basic physics you ignorant. It is same like with problem of cannon shot:

The thing is: plane moves in and with atmosphere during earth rotation. It is like going in bus or riding in car. You feel force if bus/cars slows or fastens.Only then.

If bus or car would neither fastens or slows you would can feel nothing. because Force = mass * acceleration (second Newton's law of motion)

According to first Newton's law:

if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force

So If earth move with constant speed you - being on earth - cannot differ it from earth not moving.

So:

A plane is not curved to suit the curvature of the earth

1st: Curvature of earth is too small to be noticeable on those plane even if it would be curved XD - it isn't of course because it don't need it.

Second thing is physics you don't know. Do you even know why satellites not fall on earth ? https://qph.fs.quoracdn.net/main-qimg-47b3736d882ae905ca2db1e0f78a888d.webp like on a string

In case of plane there is also difference of pressures over and bellow wings,but without trust it would fall like a stone.
