double miles to DL's hubs from US's hubs for a month.

Of course, you don't get double miles BEYOND the first flight, so the earnings potential is pretty minimal (unless you're on a SLC flight, I suppose).

We'll see if US responds. A pretty petty move, IMHO, but I guess they're trying to tap the frustration with US's repeal of the 500 minimum mile rule.
