When this route gets cheap.
Fares bottom out in May around $558 and peak in December near $911, 63% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 10.5 hours outbound, on a 7-night trip — ticketed under TAP Air Portugal, which on a connecting fare need not operate every leg. At $558 for 7,218 km each way, that works out to about $39 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 10 departure cities we track at a similar distance from Rome, this fare ranks 8th — 22% above the $458 from Delhi. That puts it in the cheaper half of the 32 routes of similar length we watch out of Washington, where the middle fare is $743. The best time to be in Rome: Apr–Jun · Sep–Oct.

Good to know
WAS → ROM, answered.
Is $558 a good price for Washington to Rome?
Only slightly. The seasonal median is around $690 round-trip and this fare is 19% 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.
What is the cheapest month to fly from Washington to Rome?
Across 5 months of cached-fare history, May comes out cheapest on this route. The best months to actually be in Rome are Apr–Jun · Sep–Oct — when those overlap, that's your window.
How far in advance should I book WAS → Rome?
We do not publish a number for this, because we cannot measure it yet.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, May comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Washington to Rome?
The current cheapest fares involve a connection, ticketed under TAP Air Portugal. 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.
