Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Frontier Airlines.

Frontier on LAS to ELP lands a B+, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 262 flights, with a median arrival 13 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate Frontier on LAS to ELP from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on LAS to ELP, 1,316 flights

These figures cover 262 flights between July 2025 and June 2026. The median arrival is 13 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.

Carrier by carrier

Frontier against every carrier on LAS to ELP

Frontier flew 262 of the 1,316 flights on LAS to ELP, about 20% of it. Its 80.8% on time is 7 points better than the route as a whole, which runs 74.3%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Frontier at 80.8% to Southwest at 72.8%.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

When Frontier runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 19 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

8am–11am93 flights91.4%
11am–2pm17 flights—

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 91.4% of the time, against 72.6% for the afternoon window. That is 19 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 93 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.8% on time across 262 flights.

Frontier on LAS to ELP did not run the same all year. Its best quarter was Jul–Sep 2025 at 89.3% on time and its weakest Apr–Jun 2026 at 71.0%, a swing of 18 points on roughly 66 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Delay causes

Why Frontier runs late on this route

One category carries most of the weight here. Late-arriving aircraft accounts for 79% of the 4,327 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Late-arriving aircraft
79%
Carrier
14%
National Airspace System
7%

79% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 4,327 reported delay minutes here, that single category outweighs weather by 79 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 4,327 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 91.4% on time here.

Cancellations are rare at 0.76%, below the national 1.81% 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

6.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

The 584 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 81.0% on time across 262 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. 262 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 LAS to ELP

Put together: treat all of this as provisional. 262 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 80.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 260 completed flights over 12 months sit behind that.
