Not the case by any strecth. UA uses C for full-Business Class. The tougher one are the carriers which make up names for the class of service. On a three-class aircraft, I think of it as First, Business and Economy, whatever marketing cr** name they make up. If 4-class, I think of it as Premium Economy.
