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 327 of the 358 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

A 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.3%, and MQ 3812 runs level with that at 78.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

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 93.3% on time and its weakest Oct–Dec 2025 at 67.0%, a swing of 26 points on roughly 72 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.

Scale runs 60% to 100%.
By weekday, MQ 3812 did best on Saturday at 87.5% on time and worst on Sunday at 63.3%. Each day rests on about 51 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 3812
The latest arrival of the period was on 17 June 2026, 5 hours 26 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 June 2026 | 5 hours 26 minutes | National Airspace System |
| 21 July 2026 | 5 hours 26 minutes | National Airspace System |

Delay causes
Why MQ 3812 runs late
Late-arriving aircraft accounts for 45% of the 5,779 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 29%National Airspace System
- 13%Carrier
- 13%Extreme weather
Extreme weather accounts for 13% 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 2.1 times the usual weather exposure. The split is drawn from 5,779 delay minutes reported on MQ 3812.
Cancellations run at 2.79%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
9.2% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
MQ 3812 is not only a HPN to ORD flight. It also flew ORD to HPN (353 flights, 82.5% 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. 358 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 3812
