Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3746, 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 3746 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 13 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 327 flights, with a median arrival 15 minutes early.

Set against the rest of the country, MQ 3746's record is 13 points better than the US average of 77.6%. That gap is worth roughly 131 fewer late arrivals for every thousand flights.

These figures cover 327 flights between July 2025 and June 2026. The median arrival is 15 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 3746 flies

MQ 3746 flies BIL to DFW without a single fixed slot. Its most common scheduled departure was 06:00, used on 130 of 327 flights, with 05:27 (49 flights) and 06:42 (43 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 3746 runs level with that at 90.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, MQ 3746 ranged from 85.1% on Sunday to 95.7% on Tuesday. With about 47 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why MQ 3746 runs late

One category carries most of the weight here. Carrier accounts for 42% of the 1,979 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.

Carrier
42%
Extreme weather
32%
National Airspace System
26%

Extreme weather accounts for 32% 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 5.2 times the usual weather exposure. The split is drawn from 1,979 delay minutes reported on MQ 3746.

Cancellations are rare at 0.31%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.7% 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.

The 1,081 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

Every one of the 327 flights under MQ 3746 in the data flew BIL 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. 327 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 3746

For a booking, MQ 3746 has one of the better records a US domestic flight can show: 90.7% on time and 0.31% cancelled. That is a base rate, not a promise about any single day.
