US Airways award travel chart changed last night (the night between 2/5-2/6) on some awards up to 25% higher. I called their customers relation and they claimed they can change the rates anytime without notice...Assuming it is correct and acceptable by the terms is it a proper business ethical behavior?
Here is the award chart after the change:

Not enough there are not "Standard" bonus tickets they increase the rates.
