Updated October 22, 2019: DC have informed retailers that shipments of the new Legion flight rings will be early. Look for the rings in comic stores October 30, one week ahead of Legion of Super-Heroes #1.
Original Story from October 11, 2019: Following their debut at New York Comic Con, DC's new Legion of Super-Heroes flight rings are now available for retailers to order. In addition to the classic gold-colored rings (which DC has produced before), they are also offering platinum-colored rings as ratioed variants.
These new Legion flight rings can be ordered by retailers at $25 per 50-count bag. Comic stores also get a free bag with every 200 copies of Legion of Super-Heroes #1 ordered.
The platinum-colored Legion Flight Rings have not been made available for individual purchase; instead, retailers receive one platinum-colored ring for every 100 copies of Legion of Super-Heroes #1 they order.
While not many stores could be expected to sell-through 100 copies of Legion of Super-Heroes #1, the publisher is offering returnability on the issue if retailers order 125% of what they ordered of February 20's Batman #65 (the main cover only). That would be a relatively high bar, as Batman #65 was the third-highest selling comic book of February 2019 to the North American direct market, selling an estimated 89,123 copies according to ComicChron.
Legion of Super-Heroes #1 is due out November 6.
