"In regards to the mileage charts. Delta offers mileage charts online
for domestic and international travel to or from the US. If you are
interested in mileage requirements for other markets it would be
necessary to contact a representative at the Medallion line. At this
time Delta has no plans to add these charts to its website. We
apologize for any inconvenience this may cause."

They don't even do that much! The award chart only works if your departure or destination is in the lower 48 US! Try to figure out (for example) how many miles you need from HI to Europe (answer: it's more than 60K in Y, most likely 70K, the old NW WP low award level).
