Across the year
MQ 3377 quarter by quarter
MQ 3377 did not run the same all year. Its best quarter was Apr–Jun 2026 at 77.1% on time and its weakest Jan–Mar 2026 at 57.7%, a swing of 19 points on roughly 85 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 85%. Rows with fewer than 30 flights show a dash.
By weekday, MQ 3377 did best on Saturday at 73.3% on time and worst on Thursday at 57.8%. Each day rests on about 49 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Share of 321 completed flights by arrival against schedule.
16 of 105 late departures made up the time and arrived on time, 15% 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 FAR.
The worst days
Worst days for MQ 3377
The latest arrival of the period was on 2 July 2026, 5 hours 48 minutes behind schedule; most of its delay minutes were filed as extreme weather. On four of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 July 2026 | 5 hours 48 minutes | Extreme weather |
| 30 January 2026 | 4 hours 6 minutes | Late-arriving aircraft |

Delay causes
Why MQ 3377 runs late
Late-arriving aircraft accounts for 50% of the 6,938 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Late-arriving aircraft
- 19%National Airspace System
- 17%Carrier
- 15%Extreme weather
Extreme weather accounts for 15% 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 2.5 times the usual weather exposure. The split is drawn from 6,938 delay minutes reported on MQ 3377.
Cancellations run at 5.59%, against 1.89% nationally. That is roughly one flight in twenty 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
12.1% 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 557 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 340 flights under MQ 3377 in the data flew ORD to FAR. 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. 340 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 3377
For a booking, the cancellation rate is the figure to plan around on MQ 3377: 5.59% of its 340 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
