Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3835, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 3835 earns a B. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 7 points better than the national rate of 77.6%.

These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 9.5% 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 3835 flies

OO 3835 flies SBN to MSP without a single fixed slot. Its most common scheduled departure was 07:05, used on 141 of 365 flights, with 07:10 (55 flights) and 07:19 (40 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 07:05 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 3835 runs 5 points worse at 84.4%. 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 3835 quarter by quarter

OO 3835 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.5% on time and its weakest Jan–Mar 2026 at 69.0%, a swing of 26 points on roughly 91 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 202592 flights93.3%
Oct–Dec 202592 flights80.2%
Jan–Mar 202690 flights69.0%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, OO 3835 did best on Friday at 92.2% on time and worst on Monday at 78.8%. Each day rests on about 52 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3835 runs late

One category carries most of the weight here. Carrier accounts for 79% of the 8,144 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
79%
Extreme weather
12%
National Airspace System
8%
Security
1%

Extreme weather accounts for 12% 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 2.0 times the usual weather exposure. The split is drawn from 8,144 delay minutes reported on OO 3835.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

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. 9.5% 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 365 flights under OO 3835 in the data flew SBN to MSP. 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. 365 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.
