Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| MQ3572 | 78.1% | 0.48% | -6 min | 10.1% | 1,035 |
| Envoy Air on CMH → ORD | 76.4% | 1.21% | -6 min | 9.4% | 3,869 |
| All CMH → ORD flights | 77.6% | 1.58% | -6 min | 8.5% | 12,181 |
MQ3572 has cancelled 0.48% of its scheduled departures (5 of 1,035), against 1.58% for all CMH → ORD flights — this specific departure cancels 1.1 percentage points less often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about MQ3572 specifically, not about the route it flies.

Why MQ3572 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for MQ3572 on CMH → ORD. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies MQ3572 comes in late, and what that does to the departure.
MQ3572 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.9 hours on the ground at CMH, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, MQ3572 pushed back an average of 12 minutes late; when it came in on time or early, an average of 6 minutes late.
Each departure is matched to the flight the same aircraft flew into CMH just before it, using the tail number in the DOT file, 661 of 1,030 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| MQ3572 | 27% | 18% | 10% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often MQ3572’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often MQ3572 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves CMH late, does that still matter by the time it reaches ORD?
MQ3572 pushes back an average of 20.9 minutes late and reaches the gate at ORD an average of 17.5 minutes late. The 3.4 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. Its 16.4 minutes on the taxiways at CMH is about what any departure from the airport in that hour spends.
On arrival at ORD, MQ3572 spends 18.2 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at ORD spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached ORD. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 9,006 departures from CMH scheduled in the clock hour MQ3572 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ORD (952,666 flights), not just MQ3572’s own. More on taxi time.

The hour it leaves CMH
Part of any flight’s record belongs to the clock rather than to the flight. MQ3572 has one departure time, so this is what that time is worth.
On-time arrival rate. 9,006 departures from CMH are scheduled in the 8 AM–9 AM hour over the period, against 134,005 across the whole day.
MQ3572 is scheduled out of CMH at 8:20 AM, in the 8 AM–9 AM bank. Departures from CMH in that hour arrive on time 87.5% of the time against 82.1% across the airport’s whole day — the slot alone is worth 5.4 points better before anything about this particular flight is considered.
The two airport figures cover every departure from CMH to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does MQ3572 run worse on particular days?
Saturday is historically the most reliable day and Monday the least, a gap of 11.7 percentage points.

Other routes MQ3572 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| MIA→EWR Miami to Newark | December 7–14, 2024 | 2 | — |
| DFW→PNS Dallas–Fort Worth to Pensacola | November 30, 2024 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route MQ3572 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
63 min late
against a median of 6 min early
MQ3572 has an average that understates its risk: a typical arrival is 6 min early, but the worst tenth are 69 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| YX3524 | Republic Airways | 92.5% | 15 min early | 975 |
| MQ3446 | Envoy Air | 80.3% | 11 min early | 624 |

| UA1182 | United Airlines | 45.3% | 17 min late | 622 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. MQ3572 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 1,035 records of MQ3572 operating CMH → ORD, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
