Envoy Air · Chicago to Little Rock

Route: ORD → LIT
Departs: 18:44
Flights: 296
Period: July 2025 to June 2026

Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3561, 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 3561 draws a C−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 296 flights, with a median arrival 5 minutes early.

The national on-time rate over the same period is 77.6%, so MQ 3561 runs 10 points behind the country as a whole. Across a thousand flights that is about 98 extra late arrivals.

These figures cover 296 flights between July 2025 and June 2026. Beyond the headline rate, 11.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When MQ 3561 flies

MQ 3561 flies ORD to LIT without a single fixed slot. Its most common scheduled departure was 18:44, used on 38 of 296 flights, with 18:35 (31 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 18:44 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and MQ 3561 runs level with that at 67.8%. 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 3561 next to ORD to LIT

Every carrier on ORD to LIT combined arrived on time 74.8% of the time across 1,406 flights, so MQ 3561 is 7 points behind it. Envoy flew 953 flights on the same city pair under all its flight numbers, including this one, and those ran 75.4% on time. Across its whole network Envoy Air managed 80.2%, which this flight trails by 12 points.

Across the year

MQ 3561 quarter by quarter

MQ 3561 did not run the same all year. Its best quarter was Apr–Jun 2026 at 76.9% on time and its weakest Jul–Sep 2025 at 60.0%, a swing of 17 points on roughly 74 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.

Jan–Mar 202677 flights63.2%

Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3561 did best on Friday at 77.3% on time and worst on Saturday at 55.0%. Each day rests on about 42 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why MQ 3561 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 59% of the 6,501 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
59%
National Airspace System
22%
Extreme weather
12%
Carrier
6%

Extreme weather accounts for 12% 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 2.0 times the usual weather exposure. The split is drawn from 6,501 delay minutes reported on MQ 3561.

Cancellations run at 3.38%, against 1.81% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The 552 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 296 flights under MQ 3561 in the data flew ORD to LIT. 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. 296 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 3561

For a booking, the cancellation rate is the figure to plan around on MQ 3561: 3.38% of its 296 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
