These figures cover 331 flights between July 2025 and June 2026. Beyond the headline rate, 17.4% 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 OO 4314 flies

OO 4314 flies MSP to MQT without a single fixed slot. Its most common scheduled departure was 10:10, used on 156 of 331 flights, with 14:20 (66 flights) and 12:55 (55 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:10 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 4314 runs 10 points worse at 73.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 4314 quarter by quarter

OO 4314 did not run the same all year. Its best quarter was Jul–Sep 2025 at 84.8% on time and its weakest Jan–Mar 2026 at 55.4%, a swing of 29 points on roughly 83 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, OO 4314 did best on Tuesday at 85.7% on time and worst on Sunday at 64.6%. Each day rests on about 47 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4314 runs late

One category carries most of the weight here. Carrier accounts for 61% of the 8,609 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.

Carrier
61%
Extreme weather
34%
National Airspace System
4%

Extreme weather accounts for 34% 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 5.5 times the usual weather exposure. The split is drawn from 8,609 delay minutes reported on OO 4314.

Cancellations run at 4.23%, against 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 17.4% 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.

Every one of the 331 flights under OO 4314 in the data flew MSP to MQT. 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. 331 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 OO 4314

For a booking, the cancellation rate is the figure to plan around on OO 4314: 4.23% of its 331 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.
