Cached-fare history: across 4 months, Sep is the cheapest for CHI → BEG. Best time to be there: May–Jun · Sep–Oct.
Fares bottom out in September around $588 and peak in December near $773 — a $185 spread across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 12 hours outbound, on a 26-night trip — ticketed under LOT Polish, which on a connecting fare need not operate every leg. At $588 for 8,024 km each way, that works out to about $37 per 1,000 km flown. That is below the $44 typical of long-haul fares here. Across the 17 departure cities we track at a similar distance from Belgrade, this fare ranks 2nd — 28% above the $459 from Miami. That puts it in the cheaper half of the 36 routes of similar length we watch out of Chicago, where the middle fare is $616.

CHI → BEG, answered.
Is $588 a good price for Chicago to Belgrade?
Only slightly. The seasonal median is around $700 round-trip and this fare is 16% under it, about $112. 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 Chicago to Belgrade?
Across 4 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Belgrade are May–Jun · Sep–Oct — when those overlap, that's your window.
How far in advance should I book CHI → Belgrade?
We do not publish a number for this, because we cannot measure it yet.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, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Chicago to Belgrade?
The current cheapest fares involve a connection, ticketed under LOT Polish. 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.
