Except piloting a plane requires actual skills. Plus actually flying the thing isn’t even the hard part, it’s not that much more difficult than driving a car from what I understand. The difficult parts are doing paperwork, setting up the plane, dealing with ATC and passengers, and most of all finding a way to fund all the training and building up the flying hours without going broke.

Before any commercial plane takes off all kinds of performance calculations are done and flight plans are filled to make sure it’s actually safe. Load and balance plus fuel checks all have to be done. Pilots need to plan and brief on emergency procedures and so on, this is also done prior to landing.
