Across the year

OO 3889 quarter by quarter

Delay causes

Why OO 3889 runs late

Carrier accounts for 78% of the 7,497 delay minutes carriers reported here, and the remaining four split what is left.

Carrier
78%
Extreme weather
17%
National Airspace System
6%

Extreme weather accounts for 17% 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 2.8 times the usual weather exposure. The split is drawn from 7,497 delay minutes reported on OO 3889.

Cancellations are rare at 0.76%, below the national 1.89% 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

15.3% 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 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.

The same number turns up on two other city pairs in the data, including OMA to DTW (169) 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. 264 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. 15.3% 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.
