Wheels up/Wheels down
Here's something to discuss:
Take a high time airframe such as a 727, 737, 747 or whatever you like, but keep it in the realm of high usage (a'la international cargo, transcon flights etc.).
The question is this: Does the bird spend more time with it's gear up or down?

At the end of service life, from roll off the line to final shut down, I would put my money on more time on the ground than in the air. Definitely so for aircraft flying shorter stage lengths. Probably closer for the long-haul aircraft that fly 10 hrs at a time then swap crews and go out on another long haul in 2 hours. But I'd still guess that they spend more time shutdown, in mx, and on the gate then they do in the air.

Yeah, there's a whole bunch of time spent in heavy Mx.
Also newer planes fly a lot. Older planes (with low mortgage payments but higher operating costs) tend to fly less, like one trip per day (or week). A brand-new widebody might fly more than it sits, but only until it's first heavy Mx.
