Good timing and the TG flight will get me (domestic) lounge access in BKK for our layover, and I'm fairly confident in the PG-TG interline as it seems quite common. It was also a good price and some UA miles

Probably a wise choice to go with the 10:30 PG flight.
Just a note: PG has int and dom lounges for all pax.
