Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3839, 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 3839 sits in the middle of the pack with a B+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 277 flights, with a median arrival 8 minutes early.

These figures cover 277 flights between July 2025 and June 2026. The median arrival is 8 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 3839 flies

MQ 3839 flies BIS to DFW without a single fixed slot. Its most common scheduled departure was 14:24, used on 54 of 277 flights, with 14:58 (39 flights) and 15:00 (36 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 14:24 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and MQ 3839 runs 3 points better at 75.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

MQ 3839 quarter by quarter

Quarter by quarter MQ 3839 held fairly steady: 74.2% in Jul–Sep 2025, 77.8% in Oct–Dec 2025 and 76.1% in Jan–Mar 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, MQ 3839 did best on Tuesday at 87.5% on time and worst on Saturday at 64.9%. Each day rests on about 40 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3839 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 3,918 reported delay minutes.

Late-arriving aircraft
39%
National Airspace System
28%
Carrier
22%
Extreme weather
10%

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,918 reported delay minutes here, that single category outweighs weather by 4 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,918 delay minutes reported on MQ 3839.

Cancellations are rare at 0.72%, 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

5.9% 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 an hour, which a normal layover absorbs.

The 977 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.

The same number turns up on five other city pairs in the data, including DFW to BIS (218), MIA to SAV (43) and SAV to MIA (43), but none flew often enough under MQ 3839 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BIS to DFW only.

One caution: this is a thin sample. 277 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 3839

For a booking, MQ 3839 is one of the weaker ways to fly BIS to DFW: 5 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
