Across the year
MQ 3808 quarter by quarter
MQ 3808 did not run the same all year. Its best quarter was Jan–Mar 2026 at 76.5% on time and its weakest Jul–Sep 2026 at 60.3%, a swing of 16 points on roughly 71 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.

Scale runs 50% to 80%.
By weekday, MQ 3808 did best on Saturday at 93.6% on time and worst on Wednesday at 57.4%. Each day rests on about 50 flights, so a gap of 36 points is worth noticing but could still narrow in another year.

Share of 337 completed flights by arrival against schedule.
18 of 98 late departures made up the time and arrived on time, 18% of them. In the other direction, 23 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 ORD.
The worst days
Worst days for MQ 3808
The latest arrival of the period was on 28 July 2026, 17 hours 59 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across July, January, March, December and May, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 28 July 2026 | 17 hours 59 minutes | Late-arriving aircraft |
| 21 January 2026 | 6 hours 59 minutes | Late-arriving aircraft |

Delay causes
Why MQ 3808 runs late
Late-arriving aircraft accounts for 49% of the 11,000 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 33%National Airspace System
- 10%Extreme weather
- 8%Carrier
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 11,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 10,893 delay minutes reported on MQ 3808.
Cancellations run at 4.25%, against 1.89% nationally. That is about one flight in 25 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and routes
What a delay on this flight costs
15.4% 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 738 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 353 flights under MQ 3808 in the data flew HPN to ORD. 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. 353 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 3808
For a booking, the cancellation rate is the figure to plan around on MQ 3808: 4.25% of its 353 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
