OMA across all twelve months

These figures cover 2,067 departures from Eppley Airfield in December 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

December next to OMA's other months

Against OMA's own year, December ran 4 points worse than the twelve-month rate of 80.7%, which makes it number eleven of twelve months, best first. Either side of it, November ran 81.9% on time and January 81.4%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave OMA in December

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 26 points, against 8 points between the best and worst carrier.

5am–8am575 flights87.0%
8am–11am289 flights70.0%
11am–2pm338 flights73.6%
2pm–5pm424 flights77.8%
5pm–8pm380 flights68.4%
8pm–5am61 flights60.7%

Scale runs 50% to 90%.

The 8pm–5am window is where this operation falls apart: 60.7% on time, against 87.0% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 575 flights scheduled in it.

Across the week, Wednesday is the strongest day at 82.9% on time and Sunday the weakest at 70.1%, a spread of 13 points.

Carrier by carrier

Which airlines ran best at OMA in December

The choice of carrier is not cosmetic here. Southwest Airlines arrives on time 78.9% of the time; SkyWest Airlines manages 71.3%. Sample sizes sit next to every figure, because a two-point gap across 483 flights means less than a ten-point one.

Southwest leads SkyWest by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held OMA up in December

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 38,000 reported delay minutes.

Carrier
41%
Late-arriving aircraft
35%
National Airspace System
18%
Extreme weather
5%

35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 38,000 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 38,162 reported delay minutes.

Cancellations sit at 0.97% against a national 1.55%, which is ordinary. Diversions add another 0.10%.

9.0% of arrivals land a full hour or more behind schedule, against 10.0% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

What to do with this

Flying from OMA in December

For a December trip through OMA: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 87.0% on time, and with 9.0% of arrivals an hour or more late, a connection here deserves more slack than the same trip in February would.
