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

Frontier on MCO to LAS lands a B+, 4 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 about an hour on average. That is a workable record, not a spotless one. That rests on 461 flights. The strongest carrier on the route with a full sample, JetBlue Airways, flew 408 at 89.2% on time.

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

Every carrier on MCO to LAS, 1,900 flights

These figures cover 461 flights between July 2025 and June 2026. The median arrival is 15 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 MCO to LAS

Frontier flew 461 of the 1,900 flights on MCO to LAS, about 24% of it. Its 81.4% on time is 2 points better than the route as a whole, which runs 79.6%. Ranked by on-time rate it is number two of five carriers on the route, where the range runs from JetBlue at 89.2% to Spirit at 66.3%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. JetBlue Airways arrives on time 89.2% of the time; Southwest Airlines manages 75.9%. Sample sizes sit next to every figure, because a two-point gap across 930 flights means less than a ten-point one.

The spread between JetBlue and Southwest is 13 points, wide enough that it should decide the booking. On a hundred trips that is 13 more arrivals inside the on-time window.

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 27 points, against 13 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am118 flights90.6%
8am–11am162 flights88.2%
11am–2pm29 flights—
2pm–5pm3 flights—
5pm–8pm88 flights66.3%
8pm–5am61 flights63.9%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is where this operation falls apart: 63.9% on time, against 90.6% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 162 flights scheduled in it.

Across the year

Frontier on MCO to LAS through the year

Darker means more delays. Figures are on-time percentages.October best, April worst

October is the best month on the calendar at 94.1% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. March was the busiest month here, with 57 flights.

Across the week, Tuesday is the strongest day at 87.9% on time and Sunday the weakest at 73.5%. 14 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Frontier runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 4,742 reported delay minutes.

Carrier
34%
Late-arriving aircraft
32%
National Airspace System
21%
Extreme weather
13%

Extreme weather accounts for 13% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 4,742 reported delay minutes.

The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.6% on time here.

Cancellations are rare at 0.43%, 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

6.3% 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 about an hour, which a normal layover absorbs.

At 2,039 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.

The return leg is a different operation and performs like one: it runs 71.6% on time across 458 flights, 10 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 10 points of difference.

One caution: this is a thin sample. 461 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 MCO to LAS

Put together: treat all of this as provisional. 461 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 81.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 457 completed flights over 12 months sit behind that.
