Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3431, check with Envoy Air. Envoy Air flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

MQ 3431 lands a B−, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by roughly 55 minutes on average. That is a workable record, not a spotless one. That rests on 352 flights, with a median arrival 7 minutes early.

Set against the rest of the country, MQ 3431's record is 4 points better than the US average of 77.6%. That gap is worth roughly 42 fewer late arrivals for every thousand flights.

These figures cover 352 flights between July 2025 and June 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.

Schedule

When MQ 3431 flies

MQ 3431 flies DFW to CLL without a single fixed slot. Its most common scheduled departure was 22:40, used on 59 of 352 flights, with 22:49 (41 flights) and 22:46 (38 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 22:40 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 3431 runs 11 points better at 81.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

MQ 3431 next to DFW to CLL

Every carrier on DFW to CLL combined arrived on time 85.1% of the time across 1,214 flights, so MQ 3431 is 3 points behind it. Envoy flew 1,147 flights on the same city pair under all its flight numbers, including this one, and those ran 85.3% on time. Across its whole network Envoy Air managed 80.2%, which this flight beats by 2 points.

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%

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 71.4%. Each day rests on about 50 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3431 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 46% of the 3,230 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

46%
Carrier
35%
National Airspace System
10%
Extreme weather
9%

46% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,230 reported delay minutes here, that single category outweighs weather by 5 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,230 delay minutes reported on MQ 3431.

Cancellations run at 4.83%, against 1.81% nationally. That is about one flight in twenty 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

5.1% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 55 minutes, 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: 4.83% of its 352 scheduled flights did not operate. A late arrival costs roughly 55 minutes, but a cancellation costs the day, so leave a later option open.
