These figures cover 270 flights between September 2025 and August 2026. The median arrival is 6 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
MQ 3569 quarter by quarter
MQ 3569 did not run the same all year. Its best quarter was Jul–Sep 2026 at 85.7% on time and its weakest Apr–Jun 2026 at 64.6%, a swing of 21 points on roughly 54 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 3569 did best on Tuesday at 86.8% on time and worst on Sunday at 70.0%. Each day rests on about 39 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 3569
The latest arrival of the period was on 10 May 2026, 4 hours 30 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 May 2026 | 4 hours 30 minutes | Late-arriving aircraft |
| 24 October 2025 | 3 hours 40 minutes | Extreme weather |
| 12 July 2026 | 2 hours 46 minutes | Late-arriving aircraft |
| 24 May 2026 | 2 hours 43 minutes | Late-arriving aircraft |
| 25 April 2026 | 2 hours 40 minutes | Extreme weather |
Delay causes
Why MQ 3569 runs late
Late-arriving aircraft accounts for 49% of the 3,701 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 19%Extreme weather
- 18%Carrier
- 14%National Airspace System
Extreme weather accounts for 19% 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 3.1 times the usual weather exposure. The split is drawn from 3,701 delay minutes reported on MQ 3569.
Cancellations run at 4.07%, against 1.89% nationally. That is about one flight in 25 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
7.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The same number turns up on five other city pairs in the data, including GRK to DFW (37), ORD to SAT (24) and SAT to ORD (24), but none flew often enough under MQ 3569 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to GRK only.
One caution: this is a thin sample. 270 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 3569
For a booking, the cancellation rate is the figure to plan around on MQ 3569: 4.07% of its 270 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
