The UA website showed F class award seat available on TG476 on the same day as my TG472 flight, so I was able to get switched over to that flight.
On the day of my TG471 flight, there's no award availability showing in any class on TG475. No F class award seats on TG475 the day before or after, nor are there any F class seats open the day before or after for my FRA-BKK flight connecting to BKK-SYD, so it looks like I'll have live with the 773 on BKK-SYD for that itinerary (at least I have F class on the A380 from FRA).
Don't worry about award class availability. Check if there is revenue seats available in your cabin or service and then ask Thai to open them up for you.
