Delay causes

What held OMA up in September

Late-arriving aircraft accounts for 44% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
44%
National Airspace System
26%
Carrier
25%
Extreme weather
5%

44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 16,021 reported delay minutes.

Cancellations are rare at 0.56%, below the national 0.51% 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.

Badly late arrivals are rare here: only 3.9% land an hour or more behind schedule, against 5.4% 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.
