Across the year
MQ 3561 quarter by quarter
MQ 3561 did not run the same all year. Its best quarter was Apr–Jun 2026 at 76.9% on time and its weakest Jul–Sep 2026 at 62.7%, a swing of 14 points on roughly 78 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.

- Oct–Dec 202578 flights68.8%
- Jan–Mar 202677 flights63.2%
- Apr–Jun 202684 flights76.9%

Scale runs 55% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3561 ranged from 63.6% on Wednesday to 72.3% on Thursday. With about 45 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.
Arrival by arrival
How late MQ 3561 runs when it is late
MQ 3561 often beats the schedule: 91 of 302 completed flights, 30%, arrived 15 minutes or more early. The 96 late arrivals split 30 under half an hour, 31 between 30 and 60 minutes, and 35 an hour or more.

Share of 302 completed flights by arrival against schedule.
20 of 90 late departures made up the time and arrived on time, 22% of them. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LIT.
The worst days
Worst days for MQ 3561
The latest arrival of the period was on 1 December 2025, 8 hours 32 minutes behind schedule; most of its delay minutes were filed as extreme weather. On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 1 December 2025 | 8 hours 32 minutes | Extreme weather |
| 15 March 2026 | 6 hours 44 minutes | Late-arriving aircraft |
| 3 July 2026 | 5 hours 20 minutes | Extreme weather |
| 27 April 2026 | 5 hours 14 minutes | Late-arriving aircraft |
| 30 January 2026 | 5 hours 2 minutes | Late-arriving aircraft |
Delay causes
Why MQ 3561 runs late
Late-arriving aircraft accounts for 58% of the 7,012 delay minutes carriers reported here, and the remaining four split what is left.
- 58%Late-arriving aircraft
- 21%National Airspace System
- 14%Extreme weather
- 7%Carrier
Extreme weather accounts for 14% 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 2.3 times the usual weather exposure. The split is drawn from 7,012 delay minutes reported on MQ 3561.
Cancellations run at 3.51%, 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
11.6% 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 552 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 313 flights under MQ 3561 in the data flew ORD to LIT. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 313 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 3561
For a booking, the cancellation rate is the figure to plan around on MQ 3561: 3.51% of its 313 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.
