Thanks, seeing it now.

Some of the other Enhanced Availability certs say P & Q as the fare classes.

It seems that T/Q were always the necessary classes for coach tickets (non-enhanced vs. enhanced), so no change there.

P is definitely better than both A and G which was the old requirement for enhanced/non-enhanced inventory for domestic FC.

What's curious though, is what that maps to for business-coded flights. The old requirements were Z or I. If they now allow booking into D inventory (third from the bottom, just like P), that's a win there, too.

Also noticed that they are now hawking C+ upgrade certs on SB, too.
