Across the year
MQ 4094 quarter by quarter

The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 344 completed flights by arrival against schedule.
13 of 53 late departures made up the time and arrived on time, 25% of them. In the other direction, 23 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.

Connections and routes
What a delay on this flight costs
8.4% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
Every one of the 350 flights under MQ 4094 in the data flew CVG to ORD. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 350 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking MQ 4094
For a booking, read MQ 4094 as 81.7% on time with 1.43% cancelled over 350 flights. Those are rates from the past twelve months, not a forecast for any particular day.
