Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3894, 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 3894 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 9 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 359 flights, with a median arrival 1 minute early.

The national on-time rate over the same period is 77.6%, so MQ 3894 runs 9 points behind the country as a whole. Across a thousand flights that is about 89 extra late arrivals.

These figures cover 359 flights between July 2025 and June 2026. Beyond the headline rate, 9.6% 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 3894 flies

MQ 3894 flies CVG to ORD without a single fixed slot. Its most common scheduled departure was 09:58, used on 47 of 359 flights. 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 09:58 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and MQ 3894 runs 15 points worse at 68.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

MQ 3894 quarter by quarter

MQ 3894 did not run the same all year. Its best quarter was Jan–Mar 2026 at 82.1% on time and its weakest Jul–Sep 2025 at 56.0%, a swing of 26 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.

Jul–Sep 202592 flights56.0%
Oct–Dec 202591 flights57.8%
Jan–Mar 202685 flights82.1%
Apr–Jun 202691 flights80.0%

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3894 did best on Wednesday at 78.8% on time and worst on Friday at 57.7%. Each day rests on about 51 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3894 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 8,615 reported delay minutes.

National Airspace System
35%
Late-arriving aircraft
33%
Carrier
28%
Extreme weather
5%

35% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 2,974 minutes out of 8,615, against a national NAS share of 21%. The split is drawn from 8,615 delay minutes reported on MQ 3894.

Cancellations sit at 1.11% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 9.6% 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 ORD to CVG (47), but none flew often enough under MQ 3894 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CVG to ORD only.

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.

What to do with this

Booking MQ 3894
