Are you artistic? Anyone who took the retention bonus would have to pay it back unless they flow. So if they leave before flow, they just saved 30k right there.
When you flow, envoy gives you 70k on your last paycheck. If you leave before your flow, they don’t have to pay that. So they saved another 70k.
The other 50k is split over two years and is only paid out if you worked a certain amount of hours per year. So if you leave, you wouldn’t be eligible.

So if AA hired a future flow then they’d miss out on saving all that money. Or they can refuse to hire future flows and hire anyone else and not have to pay out.
