OMA across all twelve months

These figures cover 2,223 departures from Eppley Airfield in May 2026. 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

May next to OMA's other months

Against OMA's own year, May ran about a point better than the twelve-month rate of 80.7%, which makes it number six of twelve months, best first. Cancellations were unusually low for OMA in May, at 0.58% against 1.26% across the year. Either side of it, April ran 82.5% on time and June 75.1%, so a trip moved by a few weeks would have landed in a worse stretch.

Departure window

The best time of day to leave OMA in May

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against 9 points between the best and worst carrier.

5am–8am608 flights92.2%
8am–11am302 flights85.6%
11am–2pm459 flights82.9%
2pm–5pm384 flights72.2%
5pm–8pm423 flights73.6%
8pm–5am47 flights61.7%

Scale runs 55% to 100%.

The 8pm–5am window is where this operation falls apart: 61.7% on time, against 92.2% 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 608 flights scheduled in it.

Across the week, Saturday is the strongest day at 87.6% on time and Monday the weakest at 72.6%, a spread of 15 points.

Carrier by carrier

Which airlines ran best at OMA in May

The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 86.1% of the time; Southwest Airlines manages 77.4%. Sample sizes sit next to every figure, because a two-point gap across 682 flights means less than a ten-point one.

SkyWest leads Southwest by 9 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes

What held OMA up in May

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 31,000 reported delay minutes.

Late-arriving aircraft
37%
Carrier
34%
National Airspace System
22%
Extreme weather
7%
Security
0%

37% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 31,000 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 30,703 reported delay minutes.

Cancellations are rare at 0.58%, below the national 0.92% 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.

5.9% of arrivals land an hour or more late, close to the national 7.1%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

What to do with this

Flying from OMA in May

For a May trip through OMA: expect 81.8% on time and 0.58% cancelled, going by May 2026. The 5am–8am window was the strongest part of the day.
