Historical statistics for July 2025 to June 2026, not live status. For today’s MQ 4105, check with Envoy Air. Envoy Air flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.
MQ 4105 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 298 flights, with a median arrival 7 minutes early.
The national on-time rate over the same period is 77.6%, so MQ 4105 runs 8 points behind the country as a whole. Across a thousand flights that is about 84 extra late arrivals.

These figures cover 298 flights between July 2025 and June 2026. Beyond the headline rate, 14.0% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When MQ 4105 flies
MQ 4105 flies ORD to XNA without a single fixed slot. Its most common scheduled departure was 18:53, used on 50 of 298 flights, with 19:16 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 18:5350 flights16.8%
- Departs 19:1637 flights12.4%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 18:53 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and MQ 4105 runs level with that at 69.2%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.
Against the route
MQ 4105 next to ORD to XNA

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 75 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.
- Jul–Sep 202556 flights74.1%
- Oct–Dec 202582 flights75.6%
- Jan–Mar 202677 flights61.3%
- Apr–Jun 202683 flights66.7%
Scale runs 55% to 80%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 4105 did best on Monday at 76.6% on time and worst on Sunday at 61.7%. Each day rests on about 43 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Delay causes
Why MQ 4105 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 55% of the 6,771 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 55%Late-arriving aircraft
- 20%National Airspace System
- 17%Carrier
- 8%Extreme weather
55% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 6,771 reported delay minutes here, that single category outweighs weather by 7 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 6,771 delay minutes reported on MQ 4105.
Cancellations sit at 2.01% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.0% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
Every one of the 298 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. 298 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. 14.0% 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.
