MQ 3525 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs about 2.3 hours. That rests on 364 flights, with a median arrival 9 minutes early.
Set against the rest of the country, MQ 3525's record is 10 points better than the US average of 77.3%. That gap is worth roughly 97 fewer late arrivals for every thousand flights.

These figures cover 364 flights between September 2025 and August 2026. The median arrival is 9 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 3525 quarter by quarter
MQ 3525 did not run the same all year. Its best quarter was Jan–Mar 2026 at 96.5% on time and its weakest Oct–Dec 2025 at 81.6%, a swing of 15 points on roughly 73 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 3525 did best on Tuesday at 98.1% on time and worst on Saturday at 72.0%. Each day rests on about 52 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Worst days for MQ 3525
The latest arrival of the period was on 16 April 2026, 31 hours 31 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 16 April 2026 | 31 hours 31 minutes | Late-arriving aircraft |
| 19 July 2026 | 10 hours 18 minutes | Late-arriving aircraft |
| 7 March 2026 | 8 hours 30 minutes | Late-arriving aircraft |
| 19 June 2026 | 7 hours 6 minutes | Extreme weather |

Delay causes
Why MQ 3525 runs late
Late-arriving aircraft accounts for 54% of the 6,443 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 20%Extreme weather
- 14%Carrier
- 12%National Airspace System
Extreme weather accounts for 20% 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 3.4 times the usual weather exposure. The split is drawn from 6,443 delay minutes reported on MQ 3525.
Cancellations sit at 2.20% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
6.5% 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 2.3 hours, which a normal layover absorbs.
The same number turns up on one other city pair in the data, including MYR to DFW (1), but none flew often enough under MQ 3525 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to COU to DFW only.
One caution: this is a thin sample. 364 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 3525
For a booking, read MQ 3525 as 87.0% on time with 2.20% cancelled over 364 flights. Those are rates from the past twelve months, not a forecast for any particular day.
