Cached-fare history: across 4 months, Oct is the cheapest for WAS → CUN. Best time to be there: Dec–Apr.
Fares bottom out in October around $362 and peak in November near $442 — a $80 spread across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 6.5 hours outbound, on a 5-night trip — ticketed under American, which on a connecting fare need not operate every leg. At $362 for 2,183 km each way, that works out to about $83 per 1,000 km flown. That is above the $41 typical of short-haul fares here. Across the 4 departure cities we track at a similar distance from Cancún, this fare ranks 4th — 2.0× the $179 we hold from Chicago. For context, the middle fare among the 7 routes of similar length we watch out of Washington is $276.

WAS → CUN, answered.
Is $362 a good price for Washington to Cancún?
Only slightly. The seasonal median is around $410 round-trip and this fare is 12% under it, about $48. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Washington to Cancún?
Across 4 months of cached-fare history, Oct comes out cheapest on this route. The best months to actually be in Cancún are Dec–Apr — when those overlap, that's your window.
How far in advance should I book WAS → Cancún?
We do not publish a number for this, because we cannot measure it yet.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, Oct comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Washington to Cancún?
The current cheapest fares involve a connection, ticketed under American. 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.
