United is offering a 20% discount for coach award bookings made by October 19 for travel between January 10 and April 30 of next year within the US and Canada. Details can be found here.
While I’m not usually for domestic coach awards, 20,000 miles is a bargain. If you’re flying to a destination that United considers obscure, like, oh, I don’t know, Canada or Miami, this might just work out.
