Well, at least long enough to accumulate 250 hours of flight time, 50
hours of cross-country PIC time, a 300-mile solo cross-country flight,
etc.

Jay's kids probably have that already.

Yeah, but if Jay or his wife were CFIs, Jay's kids would already have the
other qualifications as well. As it is, I suspect with someone like Jay's
kids, the 2 x 2 hour flights with a CFI sitting next to them would be just
for the sake of paying a CFI for his time, and would serve no added benefit
to them as Commercial Students...
