These figures cover 261 flights between September 2025 and August 2026. The median arrival is 13 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.

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 3976 runs level with that at 91.1%. 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 3976 quarter by quarter
MQ 3976 did not run the same all year. Its best quarter was Oct–Dec 2025 at 95.4% on time and its weakest Jul–Sep 2025 at 80.0%, a swing of 15 points on roughly 65 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 3976 did best on Thursday at 100.0% on time and worst on Saturday at 83.3%. Each day rests on about 37 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.3% 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 DCA to ATL (65), ATL to DCA (65) and LBB to DFW (26), but none flew often enough under MQ 3976 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SGF to DFW only.
One caution: this is a thin sample. 261 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 3976
For a booking, read MQ 3976 as 91.1% on time with 1.53% cancelled over 261 flights. Those are rates from the past twelve months, not a forecast for any particular day.
