Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3641, 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 3641 sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land close to two hours behind schedule. That rests on 280 flights, with a median arrival right on schedule.

These figures cover 280 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When MQ 3641 flies

MQ 3641 flies LIT to DFW without a single fixed slot. Its most common scheduled departure was 06:00, used on 98 of 280 flights, with 08:01 (37 flights) and 07:25 (34 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 3641 runs 15 points worse at 74.2%. 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 3641 next to LIT to DFW

Every carrier on LIT to DFW combined arrived on time 73.2% of the time across 2,670 flights, so MQ 3641 is about level with it. Envoy flew 1,656 flights on the same city pair under all its flight numbers, including this one, and those ran 74.7% on time. Across its whole network Envoy Air managed 80.2%, which this flight trails by 6 points.

Across the year

MQ 3641 quarter by quarter

MQ 3641 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.1% on time and its weakest Jul–Sep 2025 at 45.3%, a swing of 45 points on roughly 70 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 202564 flights45.3%
Oct–Dec 202546 flights71.7%
Jan–Mar 202685 flights90.1%
Apr–Jun 202685 flights82.1%

Scale runs 35% to 95%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3641 did best on Tuesday at 89.2% on time and worst on Wednesday at 63.4%. Each day rests on about 40 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3641 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 7,562 reported delay minutes.

Carrier
36%
Late-arriving aircraft
34%
Extreme weather
15%
National Airspace System
14%
Security
0%

Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 7,562 delay minutes reported on MQ 3641.

Cancellations sit at 1.07% against a national 1.81%, which is ordinary. Diversions add another 0.71%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.1% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on two other city pairs in the data, including BHM to DFW (57) and AUS to ORD (5), but none flew often enough under MQ 3641 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LIT to DFW only.

One caution: this is a thin sample. 280 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 3641

For a booking, read MQ 3641 as 74.2% on time with 1.07% cancelled over 280 flights. Those are rates from the past twelve months, not a forecast for any particular day.
