Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3525, 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 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 9 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 2.2 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 9 points better than the US average of 77.6%. That gap is worth roughly 94 fewer late arrivals for every thousand flights.

These figures cover 364 flights between July 2025 and June 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.

Schedule

When MQ 3525 flies

MQ 3525 flies COU to DFW without a single fixed slot. Its most common scheduled departure was 07:10, used on 80 of 364 flights, with 07:25 (45 flights) and 06:50 (39 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 07:10 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 3525 runs 2 points worse at 87.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

MQ 3525 next to COU to DFW

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 91 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.

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3525 did best on Tuesday at 96.2% on time and worst on Saturday at 72.0%. Each day rests on about 52 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3525 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 5,961 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.

Late-arriving aircraft
50%
Extreme weather
23%
National Airspace System
15%
Carrier
12%

Extreme weather accounts for 23% 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 3.7 times the usual weather exposure. The split is drawn from 5,961 delay minutes reported on MQ 3525.

Cancellations sit at 2.20% against a national 1.81%, which is ordinary. Diversions add another 0.82%.

Connections and routes

What a delay on this flight costs

5.7% 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 about 2.2 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.
