Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 52% of the 5,862 delay minutes carriers reported here, and the remaining four split what is left.

52%
National Airspace System

Carrier

Extreme weather
6%

52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,862 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 5,862 reported delay minutes.

Cancellations are rare at 0.00%, below the national 1.89% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and stage length

What a delay here costs

13.0% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.

At 472 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5pm–8pm window matters as much as it does.

The return leg runs 69.7% on time across 232 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

One caution: this is a thin sample. 232 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.

What to do with this

Booking Frontier on DEN to OMA

Put together: treat all of this as provisional. 232 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 69.7% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 231 completed flights over 12 months sit behind that.
