As always, your best uses are to fly Delta One to Europe (excluding England) for 50,000 miles – IF you can find available award space and to book ANA First and Business class awards.
Business Class on ANA to Japan would be 35,000 – 37,000 Chase points while First Class would be 56,000 – 66,000 Chase points (depending on if you are on the West Coast (cheaper) or East Coast.
One more great use is domestically on Delta within the US or US-Mexico/Canada.
