I was in J yesterday CDG -ORD, stored my pillow and blanket in the back of the NGBC seat when I boarded, and the pillow was snatched by another passenger, probably during boarding, probably taken into economy. When I realized this 3 hours into the flight, with a full J cabin, the purser brought me a plastic wrapped pillow ands red blanket from Y, from which he tore the pillow out. So Yes, you will most likely have them.
