Not sure how long PSA has had a cadet program but this below appeared on jsfirm.com today. Follows the formulaic path of tickets, CFI, regional with a reference to flow to AA someday.
The wording difference between the jsfirm posting and PSA's own careers website is interesting.
jsfirm post says:
“ New hires at PSA are
projected to flow to American Airlines after only 6 years.”

And the PSA careers site says:
“
Guaranteed flow through to American Airlines in 6-7 years”
