MQ 3431 lands a B−, 5 points better than the national rate of 77.3%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That rests on 352 flights, with a median arrival 7 minutes early.

These figures cover 352 flights between September 2025 and August 2026. The median arrival is 7 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 3431 quarter by quarter
MQ 3431 did not run the same all year. Its best quarter was Jan–Mar 2026 at 88.2% on time and its weakest Apr–Jun 2026 at 75.6%, a swing of 13 points on roughly 88 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 202582 flights86.4%
- Jan–Mar 202689 flights88.2%
- Apr–Jun 202691 flights75.6%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3431 did best on Tuesday at 91.3% on time and worst on Sunday at 73.5%. Each day rests on about 50 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

The latest arrival of the period was on 21 May 2026, 7 hours 45 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 May 2026 | 7 hours 45 minutes | Carrier |
| 12 April 2026 | 2 hours 6 minutes | Late-arriving aircraft |
| 15 March 2026 | 2 hours 4 minutes | Late-arriving aircraft |

Delay causes
Why MQ 3431 runs late
Late-arriving aircraft accounts for 45% of the 3,473 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 38%Carrier
- 10%National Airspace System
- 6%Extreme weather
45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,473 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 3,473 delay minutes reported on MQ 3431.
Cancellations run at 3.98%, 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
6.2% 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.
Every one of the 352 flights under MQ 3431 in the data flew DFW to CLL. 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. 352 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 3431
For a booking, the cancellation rate is the figure to plan around on MQ 3431: 3.98% of its 352 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
