Yes. None over the Pacific, but 4 over the Atlantic - and three of them had bumpy moments.
A bunch over Eastern Canada/Eastern seaboard. All of those were small commuter flights - so all of them had some bump.
But to your point - Yes, I’ll agree with you that flights now are a lot smoother than from when the movie came out.
Good writing? Ha.
Inception makes a point of introducing us to “The Kick”. You remember the scene. We all remember the scene, because it is crucial to the story telling.
So the plan was to put a guy to sleep, go a few layers deep into the minds of multiple people, all of whom need a kick to wake up…and they decide to do this on an AIRPLANE.
An AIRPLANE. In flight. Across the ocean. All of them dozing off in first class, in various stages of sleep. In turbulent, kick inducing, skies.
Cherry on top - Buddy bought the airline just to make it easier.
Christopher Nolan tries to hide his shoddy writing with flashy edits and quick quips about the plot, hoping to distract the viewer from his lacking skill.
The hospital escape is my favorite scene in any movie.
