United: Discounted Mileage Plus Reward flights to the U.S.

United Mileage Plus is offering a 5,000 mile discount on Economy Saver flights between the U.S. and Canada, which means reward flights can be had for 20,000 miles if they are available.

Although it looks to be targetted to the U.S. market for travel to Canada, the terms and conditions do not state that Canada to U.S. travel is excluded. Here is a link to the offer. (I tried a dummy booking for YYC-DEN and it came up with 20K so it does work from Canada)
