How do I buy these PQM? Do I need to do it in conjunction with a ticket purchase only? Thanks

EDIT. Wow. I just figured this out for myself (buy award accelerator and select option for premier accelerator). In one case my trip IAD-SFO I can get 10k EQM for 250 buck and (apparently 10k EQM for 1k). It's an interesting option and it seems like a win-win. It's like paying for a mile-run without having to actually take the time and effort to do the flight. UA gets the benefit of being able to sell the seat to someone else. Frankly it seems like a smart business move.
