How MQ3711 performs
613 operations, July 2023 – August 2026.
Between its first and last recorded date on BOS → ORD, MQ3711 averaged about 4 operations a week (613 in 1,158 days, cancelled ones included).
MQ3711 arrived on time 75.4% of the time, against 76.4% for all BOS → ORD flights, so this departure is 1.0 percentage points worse than the route as a whole. Against Envoy Air’s own flights on this route it is 3.2 points worse.
MQ3711’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 3:30 PM earlier on, and around 2:00 PM more recently — a 90-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| MQ3711 | 75.4% | 1.96% | -7 min | 13.7% | 613 |
| Envoy Air on BOS → ORD | 78.6% | 2.28% | -11 min | 10.5% | 1,447 |
| All BOS → ORD flights | 76.4% | 2.01% | -7 min | 10.3% | 22,677 |
MQ3711 cancelled 12 of 613 operations (1.96%), close to the 2.01% for BOS → ORD.
13.7% of MQ3711’s arrivals were an hour or more late, against 10.3% across BOS → ORD, so the long delays are more common on this number than on the route.

Why MQ3711 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
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for MQ3711 on BOS → ORD. Only delays of 15 minutes or more are attributed. What the five causes mean

Does a late aircraft delay this flight?
How often the plane that flies MQ3711 comes in late, and what that does to the departure.
The aircraft flying MQ3711 came in 15 or more minutes late on 20% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.
Matched by tail number to the aircraft’s previous flight into BOS: 590 of 604 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late |
|---|---|
| MQ3711 | 20% |
| Network, same turn | 18% |
Little slack sits between the inbound landing and this departure, so a late arrival has almost nowhere to go but into the departure.
The network row is every flight with a scheduled turn of 30 to 44 minutes. How often MQ3711’s aircraft landed 15 or more minutes late is about the same as the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate
When it leaves BOS late, does that still matter by the time it reaches ORD?
MQ3711 pushes back an average of 18.0 minutes late and reaches the gate at ORD an average of 13.1 minutes late. The 4.9 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 22.3 minutes on the taxiways at BOS, 1.4 minutes longer than a typical BOS departure in the same hour.
On arrival at ORD, MQ3711 spends 20.1 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 2.2 minutes longer than a typical ORD arrival (18.0 min).
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 28,990 BOS departures. Taxi-in is landing to gate, set against 985,848 arrivals at ORD. More on taxi time.

The hour it leaves BOS
MQ3711 has one departure time, 3:30 PM, so this is what that hour at BOS is worth.
On-time arrival rate. 28,990 departures from BOS are scheduled in the 3 PM–4 PM hour over the period, against 454,081 across the whole day.
MQ3711 is scheduled out of BOS at 3:30 PM, in the 3 PM–4 PM bank. Departures from BOS in that hour arrive on time 70.9% of the time against 77.0% across the airport’s whole day — the slot alone is worth 6.1 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from BOS, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
82 min late
against a median of 7 min early
MQ3711 has an average that understates its risk: a typical arrival is 7 min early, but the worst tenth are 89 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 613 records of MQ3711 operating BOS → 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 reported separately, not in the on-time rate.
