After raising prices for business class, at least double in past 6 months, bc is no longer open nor pre boarded. We had to walk 3 cars up when boarding at Chicago union station. Then 3 cars back to bc. I voiced displeasure to conductor and he replied that the state of Illinois had written a memo stating that this was the way things would be fine from now on. If this the case this is the most stupid ASSinine thing that I have ever seen.
