WAS-NYP on the regional train is pricing $49. System says that upgrade to business is $40. Click on that, it says estimated price is $89. But when I click through, it prices $120 or an extra $31. Why? I have no problem clicking through and pricing a coach seat at $49. But the base fare becomes $80 when I select the business upgrade. Will they just not upgrade the lower priced fare, despite promises on the website? I called and the automated phone system does the same as the website. Any insight appreciated!
