My Anecdata - I moved from London to SF ~4 years ago (working for the same FAANG company before-and-after), and have never even bothered looking at my PTO accrual because a) I wouldn't even spend it fast enough to run it down, and b) my managers have always been very clear that I should take whatever PTO I want whether or not I officially have hours accrued.

Officially, though, I (just found out that I) have 20 discretionary days per year (plus American holidays).
