When I try to do this, on the advanced search page, the results are shown in 3 or four columns. First is an economy fare, second is the business class fare, then the next column is an upgradeable first class fare and there is nothing in this field because there are no first-class seats on the PS flight. It won't show me how much it costs for an economy to business upgrade.
