So I've finally got enough points I can consider doing some sort of redemption. Looking at the terms on the upgrades I probably can't use them since I am required to book deep-discount for work (cheapest fare). That leaves actual travel redemptions. Looking at them, it looks like the standard PlanAAhead = MilesAAver award. Correct? So I'd order the award, then use the award to book?

Can I put a MilesAAver award on hold, order the BE award, then use it to "purchase" the on-hold award, or is it a different booking process all together?
