Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 3704, 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 3704 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 15 points better than the national rate of 77.6%. When something does go wrong the average delay runs an hour and a half. That rests on 254 flights, with a median arrival 14 minutes early.

Set against the rest of the country, MQ 3704's record is 15 points better than the US average of 77.6%. That gap is worth roughly 147 fewer late arrivals for every thousand flights.

These figures cover 254 flights between July 2025 and June 2026. The median arrival is 14 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 3704 flies

MQ 3704 flies LSE to ORD without a single fixed slot. Its most common scheduled departure was 06:00, used on 187 of 254 flights, with 05:09 (30 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 3704 runs 3 points better at 92.3%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

MQ 3704 next to LSE to ORD

Across the year

MQ 3704 quarter by quarter

Quarter by quarter MQ 3704 held fairly steady: 93.4% in Jul–Sep 2025, 89.8% in Oct–Dec 2025, 92.4% in Jan–Mar 2026 and 93.6% in Apr–Jun 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.

Jul–Sep 202561 flights93.4%
Oct–Dec 202562 flights89.8%
Jan–Mar 202684 flights92.4%

Scale runs 80% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, MQ 3704 ranged from 88.9% on Friday to 97.1% on Sunday. With about 36 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why MQ 3704 runs late

One category carries most of the weight here. National Airspace System accounts for 43% of the 1,825 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.

National Airspace System
43%
Extreme weather
32%
Carrier
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 5.1 times the usual weather exposure. The split is drawn from 1,825 delay minutes reported on MQ 3704.

Cancellations run at 3.15%, 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

Badly late arrivals are rare here: only 2.8% 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 same number turns up on three other city pairs in the data, including ORD to PIA (28), CLT to CHS (13) and GRB to ORD (12), but none flew often enough under MQ 3704 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LSE to ORD only.

One caution: this is a thin sample. 254 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 3704

For a booking, the cancellation rate is the figure to plan around on MQ 3704: 3.15% of its 254 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
