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 14 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 280 flights, with a median arrival 16 minutes early.
Set against the rest of the country, MQ 3704's record is 14 points better than the US average of 77.3%. That gap is worth roughly 135 fewer late arrivals for every thousand flights.

These figures cover 280 flights between September 2025 and August 2026. The median arrival is 16 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 205 of 280 flights, with 05:09 (30 flights) next.
- Departs 06:00205 flights73.2%

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 level with that at 90.8%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
MQ 3704 quarter by quarter
Quarter by quarter MQ 3704 held fairly steady: 89.8% in Oct–Dec 2025, 92.4% in Jan–Mar 2026, 93.6% in Apr–Jun 2026 and 85.2% in Jul–Sep 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202562 flights89.8%
- Jan–Mar 202684 flights92.4%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3704 did best on Sunday at 97.4% on time and worst on Friday at 84.6%. Each day rests on about 40 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

The worst days
Worst days for MQ 3704
The latest arrival of the period was on 6 March 2026, 8 hours 31 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. The five worst days are spread across March, February, July, August and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 8 hours 31 minutes | National Airspace System |
| 20 February 2026 | 6 hours 37 minutes | Extreme weather |
| 2 July 2026 | 3 hours 13 minutes | Extreme weather |
| 14 August 2026 | 2 hours 42 minutes | Carrier |

Delay causes
Why MQ 3704 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 2,433 reported delay minutes.
- 35%Extreme weather
- 33%Carrier
- 32%National Airspace System
Extreme weather accounts for 35% 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 5.8 times the usual weather exposure. The split is drawn from 2,433 delay minutes reported on MQ 3704.
Cancellations run at 3.21%, against 1.89% 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 4.1% land an hour or more behind schedule, against 8.3% 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 CLT to CHS (13), GRB to ORD (12) and ORD to PIA (2), 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. 280 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: 3.21% of its 280 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.
