DL, however, charges sometimes 2x+ more miles for the same sector flights as other FFPs (talking about the normal "lowest" price). So, what is crazy here is the high cost in miles AND the $ component. If it was normal cost in miles + high fee, that's one thing, or vice versa. But DL of course has to have its cake and eat it too.
