Not familiar with other SkyTeam partners, but DL offers Skysaver awards (capacity controls) and Skychoice awards (standard, no capacity controls, if a seat is available in the requested cabin, it's yours). This year, DL is running a promo which allows PMs to redeem up to six tickets at one time only at Skysaver award mileage levels. So whether you utilize this option to book six business tickets for a family vacation to Europe or Asia, or a coach ticket for Mom between SLC and LAS, once it is used, it's used.
