Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3983, 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 3983 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 40 minutes. That rests on 253 flights, with a median arrival 11 minutes early.
Set against the rest of the country, MQ 3983's record is 7 points better than the US average of 77.6%. That gap is worth roughly 70 fewer late arrivals for every thousand flights.

These figures cover 253 flights between July 2025 and June 2026. The median arrival is 11 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 3983 flies
MQ 3983 flies DFW to LRD without a single fixed slot. Its most common scheduled departure was 08:35, used on 91 of 253 flights, with 08:08 (71 flights) and 08:12 (32 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 08:35 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and MQ 3983 runs level with that at 84.6%. 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 3983 next to DFW to LRD

Across the year
MQ 3983 quarter by quarter
MQ 3983 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.7% on time and its weakest Jul–Sep 2025 at 78.0%, a swing of 13 points on roughly 84 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.

By weekday, MQ 3983 did best on Sunday at 94.3% on time and worst on Friday at 80.0%. Each day rests on about 36 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 3983 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 1,497 reported delay minutes.
- 34%Carrier
- 32%Late-arriving aircraft
- 27%National Airspace System
- 7%Extreme weather
No single cause dominates. carrier at 34%, late-arriving aircraft at 32% and national airspace system at 27% split the 1,497 reported delay minutes between them. An even spread like this usually means the operation is running close to its designed capacity with no one obvious weak point, and it is the hardest pattern for a traveller to route around. The split is drawn from 1,497 delay minutes reported on MQ 3983.
Cancellations run at 2.77%, against 1.81% nationally. That is roughly one flight in 40 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
Badly late arrivals are rare here: only 3.3% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
MQ 3983 is not only a DFW to LRD flight. It also flew LRD to DFW (253 flights, 86.5% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.
One caution: this is a thin sample. 253 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 3983
