at least you have biz!
consider it differently:
connecting flight inside France have no biz at all.
some months ago I was back with a C ticket from JNB to CDG and then NCE. CDG NCE has no biz at all! After about 12 hours good upper deck 744, the worst can happen you is to have one hour and half on a A321 CDG - NCE flight overcrowded in Y. That's why last week I decided to have NCE -LON -PHL on BA and back instead of NCE-CDG-PHL on AF at about the same price. It's absurd to arrive early in the morning in Europe after a transatlantic overnight flight and cannot go on sleep if you paid a full C fare. Many French res. outside Paris are connecting to London, Frankfurt, Milan, etc for the same reason. It's hard to understand, but obviously should be a matter of numbers.
