Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4326, 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 4326 lands a B+, 2 points better than the national rate of 77.6%. About one flight in five 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 287 flights, with a median arrival 7 minutes early.

These figures cover 287 flights between July 2025 and June 2026. Beyond the headline rate, 8.8% 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 4326 flies

MQ 4326 flies ORD to ALO without a single fixed slot. Its most common scheduled departure was 12:30, used on 44 of 287 flights, with 13:26 (39 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 12:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and MQ 4326 runs level with that at 79.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

MQ 4326 quarter by quarter

MQ 4326 did not run the same all year. Its best quarter was Jul–Sep 2025 at 84.6% on time and its weakest Jan–Mar 2026 at 70.3%, a swing of 14 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.

By weekday, MQ 4326 ranged from 72.3% on Friday to 81.2% on Wednesday. With about 41 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why MQ 4326 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 64% of the 4,454 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.

Late-arriving aircraft
64%
National Airspace System
21%
Carrier
8%
Extreme weather
7%

64% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,454 reported delay minutes here, that single category outweighs weather by 9 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,454 delay minutes reported on MQ 4326.

Cancellations are rare at 0.70%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

8.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

MQ 4326 is not only a ORD to ALO flight. It also flew ALO to ORD (279 flights, 61.3% 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. 287 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.
