When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 20.5 hours outbound, on a 4-night trip — ticketed under KLM, which on a connecting fare need not operate every leg. At $1,691 for 15,953 km each way, that works out to about $53 per 1,000 km flown. That is above the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 10 departure cities we track at a similar distance from Mauritius, this fare ranks 6th — 2.0× the $850 we hold from Washington. For context, the middle fare among the 22 routes of similar length we watch out of Chicago is $1,085. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Mauritius: May–Dec.

The median cached fare across this calendar is 7% higher than when tracking began on 8 Aug — $1,575 then versus $1,691 now, across 5 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $1,522, on 28 Sep.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
CHI → MRU, answered.
How far in advance should I book CHI → Mauritius?
We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Chicago to Mauritius?
The current cheapest fares involve a connection, ticketed under KLM. 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.
