Historical statistics for July 2025 to June 2026, not live status. For today’s OO 3889, 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 3889 sits in the middle of the pack with a C+. About seven flights in ten arrive on time by the DOT's definition, 6 points worse than the national rate of 77.6%. The late ones land an hour and a half behind schedule. That rests on 262 flights, with a median arrival 6 minutes early.

The national on-time rate over the same period is 77.6%, so OO 3889 runs 6 points behind the country as a whole. Across a thousand flights that is about 64 extra late arrivals.

These figures cover 262 flights between July 2025 and June 2026. Beyond the headline rate, 15.4% 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 3889 flies

OO 3889 flies DTW to OMA without a single fixed slot. Its most common scheduled departure was 15:50, used on 110 of 262 flights, with 16:00 (48 flights) and 15:55 (43 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 15:50 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 3889 runs level with that at 71.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 3889 quarter by quarter

OO 3889 did not run the same all year. Its best quarter was Apr–Jun 2026 at 84.8% on time and its weakest Oct–Dec 2025 at 60.8%, a swing of 24 points on roughly 87 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 3889 did best on Friday at 83.8% on time and worst on Sunday at 62.8%. Each day rests on about 37 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 3889 runs late

One category carries most of the weight here. Carrier accounts for 72% of the 7,303 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
72%
Extreme weather
20%
National Airspace System
8%

Extreme weather accounts for 20% 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 3.2 times the usual weather exposure. The split is drawn from 7,303 delay minutes reported on OO 3889.

Cancellations are rare at 0.76%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

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. 15.4% 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.

The 650 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.

The same number turns up on two other city pairs in the data, including OMA to DTW (107) and ATL to SHV (62), but none flew often enough under OO 3889 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DTW to OMA only.

One caution: this is a thin sample. 262 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 3889

For a booking, OO 3889 is a flight to put a long connection behind. 15.4% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
