Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3887, 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 3887 lands a B, 3 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 358 flights, with a median arrival 7 minutes early.

These figures cover 358 flights between July 2025 and June 2026. The median arrival is 7 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 3887 flies

MQ 3887 flies DFW to CMI without a single fixed slot. Its most common scheduled departure was 18:49, used on 83 of 358 flights. 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 18:49 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and MQ 3887 runs 12 points better at 80.1%. 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 3887 next to DFW to CMI

Every carrier on DFW to CMI combined arrived on time 84.1% of the time across 723 flights, so MQ 3887 is 4 points behind it. Across its whole network Envoy Air managed 80.2%, close to this flight's figure.

Across the year

MQ 3887 quarter by quarter

MQ 3887 did not run the same all year. Its best quarter was Jan–Mar 2026 at 90.9% on time and its weakest Apr–Jun 2026 at 70.4%, a swing of 21 points on roughly 90 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 3887 did best on Friday at 88.2% on time and worst on Sunday at 73.5%. Each day rests on about 51 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3887 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 4,922 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.

51%
Extreme weather
23%

Carrier
11%

Extreme weather accounts for 23% 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 3.7 times the usual weather exposure. The split is drawn from 4,922 delay minutes reported on MQ 3887.

Cancellations sit at 2.23% against a national 1.81%, which is ordinary. Diversions add another 0.84%.

Connections and routes

What a delay on this flight costs

7.8% 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 692 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 358 flights under MQ 3887 in the data flew DFW to CMI. 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. 358 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 3887
