From Jiuzhaigou to Huanglong then to airport?

Hi,
I want to go to Huanglong Scenic area after a stay at JZG. I need to catch my flight from JZG to Chengdu at 6pm. So, I plan to bring along my luggage to Huanglong. Is there any idea I can store my luggage at the luggage counter at Huanglong, so I don't have to get back to JZG and rush to airport again?
