This is urban legend. Your searches alone have nothing to do with how inventory management manages class availability on flights. There is outbound G class on DL91 ZRH-ATL open on July 2, 4, 16, and 25 (which is pretty much exactly the same as a couple days ago). There is still G open on DL52 JFK-ZRH on both August 12 and 13 (again, the same as a couple days ago).
Unfortunately, there is still only P bucket open on DL52 ZRH-ATL for both July 22 and 23. Note that post #2 above was looking at US point-of-sale inventory which has A bucket open on July 22. Search should have been done from CH point-of-sale and both July 22 and 23 only have P inventory availability from CH point-of-sale as there can be different inventory availabiity on flights based on point-of-sale.
DL fares above are GH0DI5JB fares which appear to only be available from DL/AF/KL websites (they don't appear on EF). They must be purchased by Nov 30th. GH04UBJB published fares look to be $25 more each way and Sales Expiration is showing as Oct 16th.
