I've got the end of a mileage run coming up, which requres me to go AA NRT-SJC-LAS-SJC. I'd love to check a piece of luggage, but don't think the turnaround at LAS will allow it.

If I snag the luggage at customs in SJC, and get bussed to the terminal, is there someplace in the arrivals area or in the terminal to rent a locker or otherwise check it until I return from LAS a couple hours later? Thanks in advance to anyone who knows....
