Despite the Plat status, mostly they don't (arrive). If they do, it varies wildly. I got one one 7 days out (not a Y or even an H fare) but mostly my upgrades have been at the gate. I'm less than 50%, even on H fares. I'l have done about 40 segments this year by the end of this week and am getting really tired of CO. Excuse the brief vent...
