You did not receive the memo: SkyPriority is a fully-diluted product with zero value, except, in some cases, the SkyPriority security lane at some airports. Don't count on it saving you any time during the boarding process.

IMHO, when DL started offering SkyPriority to everyone with a DL AMEX, as well as offered it "for sale" on their web site, it no longer qualified as a "benefit."

The way that DL advertises SkyPriority is a red herring.
