Yesterday I made reservations to fly from BOS to the west coast and back, wanting to use my RUCs before they expire in January. If you log in before (or during) your search, the search results will indicate for which flights First or D1 are available for upgrades. For D1 flights, some of them say that the upgrade to D! requires a GUC rather than an RUC. For other D1 flights, an RUC is sufficient. Does anyone know the basis for requiring different upgrade certificates for different domestic D1 flights? Or is this a bug? The agent with whom I talked this morning did not know about this at all and said he thought it might be a bug.

I've also wondered why we can't redeem RUCs and GUCs online. I know that when I do this, I'm put on hold for quite a while while the agent contacts some other department to do this. Seems like it should be fairly simple to program the system for using RUCs and GUCs without needing an agent's involvement.

Long existing threads on this topic with Wikis and different requirements for usage. Inability to use certs online is probably one of biggest beefs with Delta.

You're messing with us, right?

This comes up in every RUC/GUC thread.

It’s not a bug. It’s all based on seats being released for upgrade by Delta. For the flights with first class, the RUC is sufficient to upgrade. You typically won’t see D1 on these same routes - lie flats in these would still be considered first class and marketed as such.

In the event that Delta is not releasing seats for the RUC, the GUC gives you access to last seat availability and thus why you see some of the flights showing available for the GUC and not the RUC.
