As a practical matter, has anyone booked a flight, applied an RUC/GUC that cleared instantly, gotten the ticket reissued (a critical piece here), and flown up front after the cert expiration? That's the way the old SWUs used to work. And I know just because the T&C say something doesn't mean DL's best-in-class IT enforces it.
The SWU T&C allowed one to fly BE up to one year after the original expiration date if the ticket was reissued, but the rules for GUCs clearly say this is not possible.
On the other hand, I extended 4 SWUs on Feb 27 by buying two refundable B fares and the next day my SWUs showed up at expired. I called DL and was told they were gone, but my BE codes and seats are still in place. I guess the drama begins when I have to reissue those tickets yet again for one reason or another.
