When this route gets cheap.
Fares bottom out in February around $223 and peak in November near $396, 78% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 9 hours outbound, on a 3-night trip — ticketed under Frontier Airlines, which on a connecting fare need not operate every leg. At $223 for 5,418 km each way, that works out to about $21 per 1,000 km flown. That is well under the $43 per 1,000 km that medium-haul fares on this board typically run. Of the 6 departure cities we track at a similar distance from San Juan, this is the cheapest right now — 36% under the next one, San Francisco. It is also the 2nd cheapest of the 9 routes of similar length we watch out of Los Angeles. The best time to be in San Juan: Dec–Apr.

Good to know
LA → SJU, answered.
Is $223 a good price for Los Angeles to San Juan?
Yes — the seasonal median for this route is around $380 round-trip. At $223 you're 41% below that, which we rate rare for this route.
What is the cheapest month to fly from Los Angeles to San Juan?
Across 4 months of cached-fare history, Feb comes out cheapest on this route. The best months to actually be in San Juan are Dec–Apr — when those overlap, that's your window.
How far in advance should I book LA → 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 4 months of cached fares, Feb comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Los Angeles to San Juan?
The current cheapest fares involve a connection, ticketed under Frontier Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). 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.
