Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3783, 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 3783 lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 314 flights, with a median arrival 7 minutes early.

These figures cover 314 flights between July 2025 and June 2026. Beyond the headline rate, 9.1% 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 3783 flies

OO 3783 flies IAD to MSP without a single fixed slot. Its most common scheduled departure was 14:15, used on 75 of 314 flights, with 12:00 (47 flights) and 11:58 (37 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 14:15 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 3783 runs 8 points better at 80.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 3783 quarter by quarter

OO 3783 did not run the same all year. Its best quarter was Jul–Sep 2025 at 88.0% on time and its weakest Jan–Mar 2026 at 69.2%, a swing of 19 points on roughly 79 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 3783 did best on Friday at 85.4% on time and worst on Wednesday at 70.0%. Each day rests on about 45 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3783 runs late

One category carries most of the weight here. Carrier accounts for 58% of the 5,484 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
58%
Extreme weather
27%
National Airspace System
15%

Extreme weather accounts for 27% 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 4.3 times the usual weather exposure. The split is drawn from 5,484 delay minutes reported on OO 3783.

Cancellations sit at 0.96% against a national 1.81%, which is ordinary. Diversions add another 0.64%.

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. 9.1% 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 907 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.

OO 3783 is not only a IAD to MSP flight. It also flew MSP to IAD (314 flights, 79.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 314 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.
