Delay causes
Why Frontier runs late on this route
Late-arriving aircraft accounts for 70% of the 8,316 delay minutes carriers reported here, and the remaining four split what is left.
- 70%Late-arriving aircraft
- 14%National Airspace System
- 13%Carrier
- 3%Extreme weather
70% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,316 reported delay minutes here, that single category outweighs weather by 22 to one. The split is drawn from 8,316 reported delay minutes.
Cancellations are rare at 0.43%, below the national 1.89% 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.
Connections and stage length
What a delay here costs
16.9% 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 8pm–5am 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 OMA to DEN
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.
