Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with Frontier Airlines.
Frontier on LIT to DEN lands a B+, level with the national rate of 77.3%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 120 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 365 at 83.3% on time.
The US average over the same twelve months is 77.3%, so there is little to separate Frontier on LIT to DEN from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Delay causes
Why Frontier runs late on this route
Carrier accounts for 46% of the 2,977 delay minutes carriers reported here, and the remaining four split what is left.
- 46%Carrier
- 30%Late-arriving aircraft
- 23%National Airspace System
The largest share of delay minutes, 46%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,376 of the 2,977 delay minutes reported here. The split is drawn from 2,977 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
10.8% 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.
The 771 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 runs 77.5% on time across 120 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. 120 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 LIT to DEN
Put together: treat all of this as provisional. 120 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 77.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 120 completed flights over 12 months sit behind that.
