MQ 3440 lands a B−, level with the national rate of 77.3%. About one flight in four arrives 15 minutes late or worse, and those flights are late by about 50 minutes on average. That rests on 256 flights, with a median arrival 6 minutes early.

These figures cover 256 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 3440 quarter by quarter
MQ 3440 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.7% on time and its weakest Apr–Jun 2026 at 66.0%, a swing of 18 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 202528 flights—
- Oct–Dec 202588 flights76.2%
- Jan–Mar 202690 flights83.7%
- Apr–Jun 202650 flights66.0%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3440 did best on Tuesday at 82.9% on time and worst on Friday at 65.6%. Each day rests on about 37 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Share of 244 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 47 departures that left 15 minutes late or more, only 3 made it up before arrival. In the other direction, 13 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 COU.
The worst days
Worst days for MQ 3440
The latest arrival of the period was on 4 March 2026, 3 hours 51 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 |
|---|---|---|
| 4 March 2026 | 3 hours 51 minutes | Late-arriving aircraft |
| 21 September 2025 | 3 hours 36 minutes | Late-arriving aircraft |
| 5 September 2025 | 3 hours 6 minutes | Late-arriving aircraft |
| 11 March 2026 | 1 hour 40 minutes | Late-arriving aircraft |

Delay causes
Why MQ 3440 runs late
Late-arriving aircraft accounts for 46% of the 2,862 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Late-arriving aircraft
- 25%Carrier
- 19%National Airspace System
- 10%Extreme weather
46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,862 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 2,862 delay minutes reported on MQ 3440.
Cancellations run at 3.91%, 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
6.6% 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 50 minutes, which a normal layover absorbs.
The same number turns up on three other city pairs in the data, including PHX to SEA (75), SEA to PHX (75) and DFW to FAR (27), but none flew often enough under MQ 3440 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to COU only.
One caution: this is a thin sample. 256 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 3440
For a booking, the cancellation rate is the figure to plan around on MQ 3440: 3.91% of its 256 scheduled flights did not operate. A late arrival costs about 50 minutes, but a cancellation costs the day, so leave a later option open.
