Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3919, 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 3919 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 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 291 flights, with a median arrival 9 minutes early.

Set against the rest of the country, MQ 3919's record is 14 points better than the US average of 77.6%. That gap is worth roughly 142 fewer late arrivals for every thousand flights.

These figures cover 291 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 3919 flies

MQ 3919 flies GRK to DFW without a single fixed slot. Its most common scheduled departure was 05:16, used on 121 of 291 flights, with 10:05 (44 flights) and 05:05 (44 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 05:16 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 3919 runs 3 points better at 91.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

MQ 3919 quarter by quarter

Quarter by quarter MQ 3919 held fairly steady: 92.3% in Jul–Sep 2025, 88.2% in Oct–Dec 2025, 94.1% in Jan–Mar 2026 and 93.8% in Apr–Jun 2026. A spread of 6 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, MQ 3919 did best on Sunday at 97.3% on time and worst on Saturday at 84.2%. Each day rests on about 42 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3919 runs late

One category carries most of the weight here. National Airspace System accounts for 43% of the 1,372 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
30%
Carrier

Extreme weather
10%

43% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 585 minutes out of 1,372, against a national NAS share of 21%. The split is drawn from 1,372 delay minutes reported on MQ 3919.

Cancellations sit at 2.41% against a national 1.81%, which is ordinary. Diversions add another 0.69%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.2% 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.

Every one of the 291 flights under MQ 3919 in the data flew GRK to DFW. 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. 291 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 3919

For a booking, read MQ 3919 as 91.8% on time with 2.41% cancelled over 291 flights. Those are rates from the past twelve months, not a forecast for any particular day.
