What stands out
How OO3874 compares to other flight numbers, not just to itself.
This flight stays close to typical even on its worst days, a smaller gap than 93% of 11,788 comparable flight numbers.
A typical arrival is 9 min early, and the worst tenth are only 21 minutes worse than that.

Does a late aircraft delay this flight?
How often the plane that flies OO3874 comes in late, and what that does to the departure.
OO3874 is usually the aircraft’s first flight of the day: the schedule gives it a median of 8.4 hours on the ground at OMA, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, OO3874 pushed back an average of 13 minutes late; when it came in on time or early, an average of 2 minutes early.
Each departure is matched to the flight the same aircraft flew into OMA just before it, using the tail number in the DOT file, 992 of 1,050 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| OO3874 | 14% | 14% | 5% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often OO3874’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often OO3874 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves OMA late, does that still matter by the time it reaches SLC?
OO3874 pushes back an average of 2.0 minutes late and reaches the gate at SLC an average of 2.1 minutes early. The 4.1 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 18.0 minutes on the taxiways at OMA, 1.7 minutes longer than a typical OMA departure in the same hour.
On arrival at SLC, OO3874 spends 9.4 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 2.3 minutes longer than a typical SLC arrival (7.1 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached SLC. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 3,513 departures from OMA scheduled in the clock hour OO3874 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at SLC (355,118 flights), not just OO3874’s own. More on taxi time.

The hour it leaves OMA
Part of any flight’s record belongs to the clock rather than to the flight. OO3874 has one departure time, so this is what that time is worth.
On-time arrival rate. 3,513 departures from OMA are scheduled in the 8 AM–9 AM hour over the period, against 75,007 across the whole day.
OO3874 is scheduled out of OMA at 8:25 AM, in the 8 AM–9 AM bank. Departures from OMA in that hour arrive on time 90.5% of the time against 81.7% across the airport’s whole day — the slot alone is worth 8.8 points better before anything about this particular flight is considered.
The two airport figures cover every departure from OMA to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does OO3874 run worse on particular days?
Friday is historically the most reliable day and Monday the least, a gap of 5.4 percentage points.

Other routes OO3874 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| CLE→DTW Cleveland to Detroit | November 4, 2023 | 1 | — |
| DTW→CLE Detroit to Cleveland | November 4, 2023 | 1 | — |
| MSP→GRB Minneapolis to Green Bay | July 5, 2023 – September 4, 2023 | 50 | — |
Because the same number has served different journeys, the statistics above describe only the route OO3874 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 1,053 records of OO3874 operating OMA → SLC, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
