Even before the PS 752, or since the first time I ever flied UA, I always know only 3 class planes have F, C, Y. And 2 class plane (no matter it is a 737, 757, 767, 777, or airbus) always have F and Y only. C and Y is not very common on airlines, only know that some oneworld airlines often use J and Y instead of F and Y. Although it may sell as 3 class on the continuation of an international flight, e.g. UA 895 EWR-ORD on a 752 would sell as F,C,Y even it only has F and Y, since the flight would be changed to a 744 at ORD to HKG.
