Fares bottom out in January around $415 and peak in July near $1,004, 142% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13 hours outbound, on a 16-night trip — ticketed under Turkish Airlines, which on a connecting fare need not operate every leg. At $437 for 9,861 km each way, that works out to about $22 per 1,000 km flown. That is well under the $44 per 1,000 km that long-haul fares on this board typically run. Across the 20 departure cities we track at a similar distance from Cairo, this fare ranks 3rd — 13% above the $388 from Dallas. It is also the cheapest of the 25 routes of similar length we watch out of Chicago. The best time to be in Cairo: Oct–Apr.

Route facts
Good to know

Across 6 months of cached-fare history, Jan comes out cheapest on this route. The best months to actually be in Cairo are Oct–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We do not publish a number for this, because we cannot measure it yet.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 6 months of cached fares, Jan comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under Turkish 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.
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.
