What the record says about this route
Cancellation, not delay, is the risk worth pricing here: 3.19% of scheduled flights never operated. A late flight still gets you there. A cancelled one leaves you rebooking, and on a route with few daily departures that can mean losing a day.
The season swings this route hard. In October it ran 29 points more punctual than in December — a difference bigger than the one between the best and worst airlines on most routes. If the date is flexible, it is worth more than the carrier.
Only Envoy Air flies this route in the published record, so there is no choice to weigh — the route's figures and the airline's are the same figures.
The Chicago to Bloomington/Normal route sits close to the middle of the record — neither notably punctual nor notably late.

What these figures do and do not tell you
Everything on this page is counted from the flights that actually operated on ORD to BMI during January 2025 – August 2026, as reported by the airlines to the US Bureau of Transportation Statistics. "On time" is the federal definition: arriving at the gate within 15 minutes of the scheduled time.
A route's record is a description of the past, not a forecast. Weather, air traffic control and the aircraft's earlier flights that day drive most delays, and none of them are predictable from a historical rate. What the record does tell you is whether this route runs late more often than others, and which carrier on it has the better history — which is the part you can actually act on when you book.
Cancellations are counted separately from delays because they are a different problem for a traveller: a late flight still gets you there. How the grade is calculated →
