Your situation is a little different. Since you're Plat, under the new rules you're allowed to upgrade a companion at the same 5-day advance window as yourself. The original poster, as a Gold, would have to split the reservation to get the 3-day upgrade. Otherwise both upgrades would clear at the 1-day Silver window, pending R availability.
