Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4254, 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 4254 lands a B, 2 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 319 flights, with a median arrival 6 minutes early.

These figures cover 319 flights between July 2025 and June 2026. The median arrival is 6 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 4254 flies

MQ 4254 flies DFW to BMI without a single fixed slot. Its most common scheduled departure was 21:01, used on 40 of 319 flights, with 20:17 (37 flights) and 20:50 (32 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 21:01 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and MQ 4254 runs 9 points better at 79.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

MQ 4254 next to DFW to BMI

Every carrier on DFW to BMI combined arrived on time 82.2% of the time across 729 flights, so MQ 4254 is 3 points behind it. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year

MQ 4254 quarter by quarter

MQ 4254 did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.4% on time and its weakest Apr–Jun 2026 at 65.2%, a swing of 21 points on roughly 80 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 202592 flights77.8%
Oct–Dec 202591 flights80.9%
Jan–Mar 202690 flights86.4%
Apr–Jun 202646 flights65.2%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 4254 did best on Tuesday at 86.7% on time and worst on Saturday at 70.5%. Each day rests on about 46 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 4254 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 4,482 reported delay minutes.

Late-arriving aircraft
41%
Extreme weather
25%
National Airspace System
18%
Carrier
17%

Extreme weather accounts for 25% 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 3.9 times the usual weather exposure. The split is drawn from 4,482 delay minutes reported on MQ 4254.

Cancellations sit at 1.88% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

7.7% 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 a little over an hour, which a normal layover absorbs.

The 690 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 one other city pair in the data, including ATW to CLT (43), but none flew often enough under MQ 4254 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to BMI only.

One caution: this is a thin sample. 319 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 4254

For a booking, read MQ 4254 as 79.2% on time with 1.88% cancelled over 319 flights. Those are rates from the past twelve months, not a forecast for any particular day.
