I just booked 2 ppl BKK-USM one-way for 5,000 miles + $3.10 tax each. Agent found the availability immediately (someone here called PG directly to confirm availability beforehand). We were able to book both pax in one booking- EY was able to see more than 1 seat at a time. We were also able to confirm availability on the phone before transferring Amex MR->EY. The transfer was instant so once the agent made the reservation, we transferred the points and she booked/ticketed it immediately. Pretty smooth.
