There's a Delta One sale I see from JFK-ZRH and vice versa for 80K miles each way.

While not a steal when comparing to AA or UA's saver levels, a lot less than DL's usual 320K-500K charges. And, it's on any metal including DL metal on the nonstop. And the nonstop is running the new interior 764 starting in late November, I believe.

When I pull up the fare rules, I don't see any validity dates, just a 90 day advance purchase requirement.
