Departs: 20:59
Flights: 301
Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3447, 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 3447 draws a D−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 301 flights, with a median arrival 1 minute early.

The national on-time rate over the same period is 77.6%, so MQ 3447 runs 13 points behind the country as a whole. Across a thousand flights that is about 128 extra late arrivals.

These figures cover 301 flights between July 2025 and June 2026. Beyond the headline rate, 14.3% 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 3447 flies

MQ 3447 flies ORD to CMH without a single fixed slot. Its most common scheduled departure was 20:59, used on 54 of 301 flights, with 20:49 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 20:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 3447 runs 6 points worse at 64.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

MQ 3447 next to ORD to CMH

Across the year

MQ 3447 quarter by quarter

Quarter by quarter MQ 3447 held fairly steady: 68.4% in Jul–Sep 2025, 62.7% in Oct–Dec 2025, 60.5% in Jan–Mar 2026 and 67.1% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202581 flights68.4%
Oct–Dec 202562 flights62.7%
Jan–Mar 202680 flights60.5%

Scale runs 50% to 75%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3447 did best on Friday at 72.5% on time and worst on Thursday at 55.3%. Each day rests on about 43 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3447 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 7,936 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.

13%

Extreme weather accounts for 20% 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 3.2 times the usual weather exposure. The split is drawn from 7,936 delay minutes reported on MQ 3447.

Cancellations run at 4.32%, against 1.81% nationally. That is about one flight in 25 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.3% 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 same number turns up on one other city pair in the data, including DSM to DFW (1), but none flew often enough under MQ 3447 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CMH only.

One caution: this is a thin sample. 301 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 3447

For a booking, the cancellation rate is the figure to plan around on MQ 3447: 4.32% of its 301 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
