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 69 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.

- Jan–Mar 202690 flights79.5%

By weekday, MQ 4322 did best on Tuesday at 90.0% on time and worst on Friday at 76.9%. Each day rests on about 39 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 4322
The latest arrival of the period was on 2 February 2026, 13 hours 8 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 February 2026 | 13 hours 8 minutes | Carrier |
| 17 January 2026 | 11 hours 33 minutes | Late-arriving aircraft |
| 23 April 2026 | 10 hours 39 minutes | Carrier |

Delay causes
Why MQ 4322 runs late
Carrier accounts for 45% of the 7,554 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 31%Extreme weather
- 17%Late-arriving aircraft
- 8%National Airspace System
Extreme weather accounts for 31% 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 5.1 times the usual weather exposure. The split is drawn from 7,554 delay minutes reported on MQ 4322.
Cancellations run at 3.26%, against 1.89% nationally. That is about one flight in 30 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
10.1% 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 same number turns up on one other city pair in the data, including MSN to ORD (28), 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. 276 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: 3.26% of its 276 scheduled flights did not operate. A late arrival costs about 2.7 hours, but a cancellation costs the day, so leave a later option open.
