Is it possible to do a back to back turnaround at GMP? Thinking of taking JL91 to connect to JL90. Arriving at GMP at 1055am and departing GMP at 1205pm. MCT is 1 hour for an Int'l-Int'l connection. I won't have any checked luggage. Assuming that this is feasible, can I get my return boarding pass in HND for the GMP-HND flight?

Thank you in advance.
