I'll echo the others; summer peak availability can be difficult to find, but with a little patience and diligence, you can probably still dig up a 25,000 mile award. If you're flexible enough to go in a shoulder season, availability should still be pretty good. I burned 50k miles just last week for 2 round-trips (booked through NW) routing EVV-CVG-ORD-ANC-SLC-ATL-EVV on DL/AS metal in early May.
