Best time to be in San Juan: Dec–Apr. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes 3 stops and takes about 23 hours outbound, on a 8-night trip — ticketed under Korean Air, which on a connecting fare need not operate every leg. At $1,044 for 15,480 km each way, that works out to about $34 per 1,000 km flown. That is below the $40 typical of ultra-long-haul fares here. Across the 4 departure cities we track at a similar distance from San Juan, this fare ranks 2nd — 4% above the $1,004 from Dubai. It is also the 3rd cheapest of the 16 routes of similar length we watch out of Hong Kong. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

How far in advance should I book HKG → San Juan?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Hong Kong to San Juan?
The current cheapest fares involve a connection, ticketed under Korean Air. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
