Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4322, 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 4322 lands a B, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.4 hours on average. That is a workable record, not a spotless one. That rests on 338 flights, with a median arrival 10 minutes early.

These figures cover 338 flights between July 2025 and June 2026. Beyond the headline rate, 10.3% 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 4322 flies

MQ 4322 flies ALO to ORD without a single fixed slot. Its most common scheduled departure was 06:00, used on 184 of 338 flights, with 05:40 (57 flights) and 05:20 (54 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 4322 runs 8 points worse at 81.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

MQ 4322 next to ALO to ORD

Every carrier on ALO to ORD combined arrived on time 71.9% of the time across 663 flights, so MQ 4322 is 10 points ahead of it. Envoy flew 617 flights on the same city pair under all its flight numbers, including this one, and those ran 72.3% on time. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year

MQ 4322 quarter by quarter

MQ 4322 did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.5% on time and its weakest Oct–Dec 2025 at 77.9%, a swing of 13 points on roughly 85 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 flights80.4%
Oct–Dec 202592 flights77.9%
Jan–Mar 202690 flights79.5%
Apr–Jun 202664 flights90.5%

Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 4322 did best on Tuesday at 89.8% on time and worst on Sunday at 76.1%. Each day rests on about 48 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4322 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 8,755 reported delay minutes.

Carrier
41%
Extreme weather
34%
Late-arriving aircraft
14%
National Airspace System
10%

Extreme weather accounts for 34% 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 5.5 times the usual weather exposure. The split is drawn from 8,755 delay minutes reported on MQ 4322.

Cancellations run at 2.66%, against 1.81% nationally. That is about 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.3% 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 MSN to ORD (27), but none flew often enough under MQ 4322 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ALO to ORD only.

One caution: this is a thin sample. 338 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 4322

For a booking, the cancellation rate is the figure to plan around on MQ 4322: 2.66% of its 338 scheduled flights did not operate. A late arrival costs about 2.4 hours, but a cancellation costs the day, so leave a later option open.
