How MQ3447 performs
712 operations, July 2023 – July 2026.
MQ3447 arrived on time 62.2% of the time, against 76.1% for all ORD → CMH flights, so this departure is 13.9 percentage points worse than the route as a whole. Against Envoy Air’s own flights on this route it is 11.1 points worse.

Why MQ3447 runs late
Where US DOT attributed the delay minutes on this flight.
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
crew, maintenance, boarding and fueling, all within the carrier’s control
Share of the delay minutes US DOT attributed to each cause for MQ3447 on ORD → CMH. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies MQ3447 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, MQ3447 pushed back an average of 44 minutes late; when it came in on time or early, an average of 7 minutes late.
Each departure is matched to the flight the same aircraft flew into ORD just before it, using the tail number in the DOT file, 661 of 696 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 |
|---|---|---|---|
| MQ3447 | 35% | 71% | 14% |
| Network, same turn | 18% | 85% | 10% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often MQ3447’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often MQ3447 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves ORD late, does that still matter by the time it reaches CMH?
MQ3447 pushes back an average of 23.4 minutes late and reaches the gate at CMH an average of 20.4 minutes late. The 3.0 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 27.3 minutes on the taxiways at ORD is about what any departure from the airport in that hour spends.
On arrival at CMH, MQ3447 spends 9.8 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 2.6 minutes longer than a typical CMH arrival (7.3 min).
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 CMH. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 66,182 departures from ORD scheduled in the clock hour MQ3447 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at CMH (134,023 flights), not just MQ3447’s own. More on taxi time.

The hour it leaves ORD
Part of any flight’s record belongs to the clock rather than to the flight. MQ3447 has one departure time, so this is what that time is worth.
On-time arrival rate. 66,182 departures from ORD are scheduled in the 8 PM–9 PM hour over the period, against 952,802 across the whole day.
MQ3447 is scheduled out of ORD at 8:20 PM, in the 8 PM–9 PM bank. Departures from ORD in that hour arrive on time 64.7% of the time against 74.5% across the airport’s whole day — the slot alone is worth 9.8 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from ORD 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.

Because the same number has served different journeys, the statistics above describe only the route MQ3447 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.
79 min late
against a median of 3 min late
MQ3447 has an average that understates its risk: a typical arrival is 3 min late, but the worst tenth are 76 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. MQ3447 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 712 records of MQ3447 operating ORD → CMH, 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.
