MQ 4073 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 12 points better than the national rate of 77.3%. When something does go wrong the average delay runs about 2.3 hours. That rests on 351 flights, with a median arrival 20 minutes early.
Set against the rest of the country, MQ 4073's record is 12 points better than the US average of 77.3%. That gap is worth roughly 122 fewer late arrivals for every thousand flights.

These figures cover 351 flights between September 2025 and August 2026. The median arrival is 20 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.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and MQ 4073 runs level with that at 89.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

The worst days
Worst days for MQ 4073
The latest arrival of the period was on 23 July 2026, 24 hours 26 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as extreme weather.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 23 July 2026 | 24 hours 26 minutes | Carrier |
| 1 January 2026 | 8 hours 27 minutes | Carrier |
| 5 May 2026 | 4 hours 2 minutes | Extreme weather |
| 30 November 2025 | 3 hours 56 minutes | Extreme weather |

Delay causes
Why MQ 4073 runs late
Carrier accounts for 54% of the 4,927 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Carrier
- 19%Late-arriving aircraft
- 14%Extreme weather
- 13%National Airspace System
Extreme weather accounts for 14% 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 2.4 times the usual weather exposure. The split is drawn from 4,927 delay minutes reported on MQ 4073.
Cancellations sit at 1.99% against a national 1.89%, which is ordinary. Diversions add another 0.28%.
Connections and routes
What a delay on this flight costs
6.1% 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 about 2.3 hours, which a normal layover absorbs.
The 692 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.
Every one of the 351 flights under MQ 4073 in the data flew CMI to DFW. 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. 351 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 4073
