This route earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs an hour and a half. That rests on 1,786 OMA to ATL flights, with a median arrival 16 minutes early.
Best time to fly OMA to ATL: a 8am–11am departure, ideally on a Tuesday. Flights in that window arrived on time 91.3% of the time and Tuesday flights 91.1%, against 87.3% for the route overall.
Set against the rest of the country, this route's record is 10 points better than the US average of 77.3%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 1,786 flights between September 2025 and August 2026. The median arrival is 16 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Book the morning departure. Flights leaving between 8am–11am arrive on time 91.3% of the time, against 82.3% for the evening window. That is 9 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 683 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 14 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
Delays peak in March, when the on-time rate falls to 82.1%. February is the strongest month at 95.8%. Moving a flexible trip across that boundary buys 14 points. March was the busiest month here, with 160 flights.
Across the week, Tuesday is the strongest day at 91.1% on time and Sunday the weakest at 83.3%, a spread of 8 points.
Delay causes
Why this route gets delayed
Carrier accounts for 59% of the 21,000 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Carrier
- 29%Late-arriving aircraft
- 10%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 59%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 12,000 of the 21,000 delay minutes reported here. The split is drawn from 20,959 reported delay minutes.
The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 91.3% on time here.
Cancellations sit at 1.62% against a national 1.89%, which is ordinary. Diversions add another 0.34%.
Connections and stage length
What a delay here actually costs
Badly late arrivals are rare here: only 4.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 821 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 return leg is a different operation and performs like one: it runs 80.8% on time across 1,785 flights, 7 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 7 points of difference.
The sample behind these figures is 1,786 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. February runs 95.8% on time and March 82.1%, a swing of 14 points. If the dates move at all, move them out of March before you think about anything else. 1,751 completed flights over 12 months sit behind that.
Common questions
OMA to ATL questions
How often is OMA to ATL delayed?
About one flight in eight arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 12.7% of the 1,786 flights in this analysis, against 22.7% nationally. Delayed flights are late by an hour and a half on average.
How reliable is OMA to ATL compared with the rest of the country?
87.3% of flights arrive on time here against a national 77.3%, a difference of 10 points in its favour. That is worth a A on this site's grading scale.
What time of day has the fewest delays on OMA to ATL?
The 8am–11am departure window is the strongest at 91.3% on time. The 5pm–8pm window is the weakest at 82.3%, 9 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are March delays on OMA to ATL?
March is the weakest month at 82.1% on time, compared with 95.8% in February. Across the year that is 14 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
