Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3812, check with Envoy Air. Envoy Air flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
MQ 3812 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 359 flights, with a median arrival 7 minutes early.

These figures cover 359 flights between July 2025 and June 2026. Beyond the headline rate, 9.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When MQ 3812 flies
MQ 3812 is scheduled to leave White Plains (HPN) at 12:00 local time and reach Chicago (ORD) at 13:43. That slot held for 319 of the 359 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and MQ 3812 runs level with that at 76.9%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.
Against the route
MQ 3812 next to HPN to ORD

Across the year
MQ 3812 quarter by quarter
MQ 3812 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.7% on time and its weakest Oct–Dec 2025 at 67.0%, a swing of 17 points on roughly 90 flights a 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.

- Oct–Dec 202592 flights67.0%
- Jan–Mar 202690 flights76.2%
- Apr–Jun 202685 flights81.0%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3812 did best on Saturday at 86.0% on time and worst on Sunday at 64.0%. Each day rests on about 51 flights, so a gap of 22 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 3812 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 5,920 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 47%Late-arriving aircraft
- 24%National Airspace System
- 15%Extreme weather
- 15%Carrier
Extreme weather accounts for 15% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 5,920 delay minutes reported on MQ 3812.
Cancellations sit at 1.95% against a national 1.81%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 738 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
MQ 3812 is not only a HPN to ORD flight. It also flew ORD to HPN (353 flights, 81.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 359 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.
