Gosh darn it.. The outbound is direct SJU-LIH, but the return seems to require LIH-LAX-SJU. I assume its considered backtracking to have a JFK arrival in August, an SJU departure in Dec, and then back thru LAX... Great loophole on a westbound itinerary, tho, with a cheap SJU R/T picked up on the side.
