You do realize, don't you, that upgrades with miles must officially be confirmed before the day of departure and cannot go to the gate like GUC/RUC upgrades, although some GAs know how to upgrade with miles and might be willing to do so if there are seats after other instrument supported upgrades have been processed and there's sufficient time.
BTW, is this a flight with D1 or D1 Suites? This thread is about upgrades to D1 Suites on the new A350 aircraft.
