39,768 cycles and 48,722 hours
As SLF, I find these numbers to be enlightening.

First, for a 15 year old plane, it is running 2,651 cycles per year, 7.26 cycles per day. That means this plane must have, on average, started out at 6 AM in the morning and hit the terminal at last flight at 9 or 10 PM at the earliest.

Second, the plane is building hours at 1.23 hrs per cycle. This suggests an awful lot of puddle jumps from Austin to Houston, to Dallas, and back again.

Seems like this plane has absolutely been beat to death, and makes me ask the question if there is some kind of "multiplier" to take into account cycles in gauging aging and airworthiness?
