Across the year
MQ 4105 quarter by quarter
MQ 4105 did not run the same all year. Its best quarter was Oct–Dec 2025 at 75.6% on time and its weakest Jan–Mar 2026 at 61.3%, a swing of 14 points on roughly 76 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 4105 did best on Monday at 74.5% on time and worst on Sunday at 61.7%. Each day rests on about 44 flights, so a gap of 13 points is worth noticing but could still narrow in another year.
Arrival by arrival

Share of 301 completed flights by arrival against schedule.
22 of 97 late departures made up the time and arrived on time, 23% of them. In the other direction, 17 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at XNA.
The worst days
Worst days for MQ 4105
The latest arrival of the period was on 4 July 2026, 5 hours 35 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 4 July 2026 | 5 hours 35 minutes | Late-arriving aircraft |
| 10 December 2025 | 4 hours 50 minutes | Late-arriving aircraft |
| 7 December 2025 | 4 hours 48 minutes | Late-arriving aircraft |

Delay causes
Why MQ 4105 runs late
Late-arriving aircraft accounts for 57% of the 7,427 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 19%National Airspace System
- 17%Carrier
- 7%Extreme weather
57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,427 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 7,427 delay minutes reported on MQ 4105.
Cancellations sit at 1.31% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
14.6% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 522 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 305 flights under MQ 4105 in the data flew ORD to XNA. 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. 305 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 4105
For a booking, MQ 4105 is a flight to put a long connection behind. 14.6% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
