Bora bora return flight options

Hi, Looking for recs on our return flight. Flight from PPT to LAX is united business class at 10:10pm.

Just wondering how early we need to arrive to PPT from bora bora.

Which flight should we take. Would love to maximize our time at the resort, just wondering if arriving at PPT at 7:20 would be pushing it or should we take the earlier flight to be safe.

Thanks!!
