MQ 4254 lands a B, 3 points better than the national rate of 77.3%. 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 rests on 317 flights, with a median arrival 6 minutes early.

These figures cover 317 flights between September 2025 and August 2026. The median arrival is 6 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.

Across the year
MQ 4254 quarter by quarter
MQ 4254 did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.4% on time and its weakest Apr–Jun 2026 at 65.2%, a swing of 21 points on roughly 79 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 4254 ranged from 74.4% on Saturday to 84.4% on Tuesday. With about 45 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 March 2026 | 11 hours 53 minutes | Extreme weather |
| 12 July 2026 | 3 hours 32 minutes | Late-arriving aircraft |
| 19 June 2026 | 2 hours 59 minutes | National Airspace System |

Delay causes
Why MQ 4254 runs late
Late-arriving aircraft accounts for 47% of the 4,318 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 21%Carrier
- 20%Extreme weather
- 12%National Airspace System
Extreme weather accounts for 20% 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 3.3 times the usual weather exposure. The split is drawn from 4,318 delay minutes reported on MQ 4254.
Cancellations sit at 1.58% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
7.7% of arrivals land an hour or more late, close to the national 8.3%, so 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 690 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.
The same number turns up on one other city pair in the data, including ATW to CLT (43), but none flew often enough under MQ 4254 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DFW to BMI only.
One caution: this is a thin sample. 317 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 4254
For a booking, read MQ 4254 as 80.1% on time with 1.58% cancelled over 317 flights. Those are rates from the past twelve months, not a forecast for any particular day.
