Thank you both ClipperDelta and xliioper for your amazing "right on" responses. As I am not a big Delta follower I was not aware of the "Schedule Change Saturday", and, as such, I do hope tomorrow or Monday the G fare is back for the flight on the 23rd.

This was there yesterday when I quoted:
Carrier DL GH04UBJB ZRH to RIC / Passenger type ADT, round trip fare, booking code G, W / Covers ZRH-ATL (Premium Economy)

Today I see only:
Carrier DL PH00ABJB ZRH to ATL / Passenger type CNN, ROUND-TRIP fare, booking code P / Covers ZRH-ATL (Premium Economy)

Anyhow... I will wait and see another few days and keep trying ....

thanks all, will report back... if you have any "alarms" and see the bucket become available, by all means, please, let me know ;-)

Thanks in advance,
