The airport line from and to the city (RER B) is literally the worst I ever took anywhere in the world. Two issues: there's no room or equipment at people's height for luggages which is infuriating. And it's shared with the local people going to and from the North suburbs, making it very crowded at times. I don't understand why there isn't a dedicated line, or at least a dedicated express train going on the line.
