I had used US Air Dividend Miles to book NY to France via Brussels Air in Business. A few weeks later, I saw that seats opened in both directions (via Frankfurt) on United. I paid the extra points and the $150pp change fee. Just checked the reservation and I have been changed to a flight with United Business First in both directions. My understanding is that these seats are usually considered Business Class yet the code (O) is still listed as First. United's own seat map confirms both flights have no true First Class. They want me to click that I accept the changes but I first want feedback. My strong feeling is that I should be calling US Air and getting 50,000 miles redeposited. Any holes in that argument? Any further advice. Many thanks.
