Across the year
MQ 3887 quarter by quarter

| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 September 2025 | 4 hours 54 minutes | Late-arriving aircraft |
| 6 June 2026 | 4 hours 44 minutes | Late-arriving aircraft |
| 26 January 2026 | 2 hours 50 minutes | Extreme weather |

Delay causes
Why MQ 3887 runs late
Late-arriving aircraft accounts for 61% of the 4,467 delay minutes carriers reported here, and the remaining four split what is left.
- 61%Late-arriving aircraft
- 15%National Airspace System
- 13%Extreme weather
- 12%Carrier
Extreme weather accounts for 13% 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 2.1 times the usual weather exposure. The split is drawn from 4,467 delay minutes reported on MQ 3887.
Cancellations sit at 2.29% against a national 1.89%, which is ordinary. Diversions add another 0.86%.
Connections and routes
What a delay on this flight costs
8.0% 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 an hour, 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 350 flights under MQ 3887 in the data flew DFW to CMI. 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. 350 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 3887
For a booking, read MQ 3887 as 80.5% on time with 2.29% cancelled over 350 flights. Those are rates from the past twelve months, not a forecast for any particular day.
