Even at 720,000, it's a screaming bargain compared to the 1,000,000 (not a misprint) ticket I got quoted yesterday for a GSP-HKG trip. I got a message informing me that I didn't have enough miles in my account, but DL would hold the ticket for me until I purchased or somehow obtained the additional miles needed. I resisted the temptation to tell them where they could hold the ticket and simply booked on another airline.
