Fares bottom out in November around $373 and peak in December near $648, 74% dearer, across the 5 months we track. The cheapest itinerary we are tracking flies Arajet nonstop and takes about 5 hours outbound, on a 5-night trip. At $373 for 3,169 km each way, that works out to about $59 per 1,000 km flown. That is above the $43 per 1,000 km typical of medium-haul fares here. Across the 8 departure cities we track at a similar distance from Punta Cana, this fare ranks 6th — 1.7× the $223 we hold from New York.

Route facts
Good to know
Only slightly. The seasonal median is around $400 round-trip and this fare is 7% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
Across 5 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Punta Cana are Dec–Apr — when those overlap, that's your window.
We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Yes — the current board includes nonstop fares (Arajet). The outbound leg runs around 5 hours.
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.
