Is it possible that I tour Huanglong on the first day and then travel to JGZ by shuttle bus?

Hi, I have check some flight timings and I can actually arrive at the airport at 7plus in the morning. Is it possible that I tour Huanglong on the first day and then travel to JGZ by shuttle bus and stay at JZG hotel for the night. 2nd day will be touring JZG for the whole day and then another shuttle bus back to the airport? Is this feasible? If so, may I know can I buy all the shuttle bus tickets at the airport? Thank you!
