During the interview, Scott talked about SWU certificates on Delta being an unredeemable perk that they'd probably be better off not even having. I really feel companion upgrades are about as useless given my stats over the last 8 years I've been Platinum. The process for requesting/processing them (R bucket released, eua list run, and the cabin almost always full well before t-2 hrs) makes the chances of actually getting on so low that it's barely worth it.
