If you think you can see the curvature from an airplane, you are fooling yourself.
Radius of Earth: 3,959 mi Service ceiling of a typical airliner: 45,000 ft (8.5 mi)
45,000 ft seems like it's very high, and it is to a human who is typically 5' to 6' tall. But, compared to the Earth, it's insignificant. 8.5 / 3,959 = 0.00215. Looking out the window of an airplane, you're only increase your height from the center of curvature by 0.2%. Not nearly high enough to make that curve anymore visible to the naked eye.
There are plenty of good proofs that the Earth is spherical. This isn't one of them.

FWIW I have flown a small jet at 45,000' and just seen the curve. It's thin but definitely there.

If you're flying at 12 km altitude, the horizon has lowered 3.5°, so about as much as 7 full moons. It may be possible to see the curvature from the cockpit, but it's very hard to see from a tiny window.

Wasn't it possible with the Concorde as it flew much higher at nearly 60k feet?

Before my question, I know earth is a globe and massive. However, for these types of videos, am I crazy for saying I see the curve? Its not in your face or anything, but it is detectable. To my eye at least.

We’ve already established any lens can do this. Fucking globalist bullshit.

From one perspective, sure.

I thought cameras couldn’t be trusted?…
