United is offering 10% off saver United economy awards within the US and Canada. To take advantage of this offer, bookings have to be made by April 12 for travel through May 26. In general domestic awards aren’t the best use of miles, but if you’re going to use miles for domestic travel anyway, might as well get a discount. For 22,500 miles, a trip to Canada might just be worth looking into since fares are usually quite high.
