These figures cover 458 flights between July 2025 and June 2026. Beyond the headline rate, 11.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Frontier against every carrier on LAS to MCO
Frontier flew 458 of the 1,906 flights on LAS to MCO, about 24% of it. Its 71.6% on time is 4 points worse than the route as a whole, which runs 75.5%. Ranked by on-time rate it is number three of five carriers on the route, where the range runs from JetBlue at 87.5% to Delta at 33.3%. 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 87.5% of the time; Southwest Airlines manages 73.3%. Sample sizes sit next to every figure, because a two-point gap across 940 flights means less than a ten-point one.

| JetBlue Airways | 408 | 87.5% | 69 min | 0.00% | A+ |
| Southwest Airlines | 940 | 73.3% | 40 min | 0.21% | C+ |

| Delta Air Linesthin sample | 3 | 33.3% | 31 min | 0.00% | F+ |
The spread between JetBlue and Southwest is 14 points, wide enough that it should decide the booking. On a hundred trips that is 14 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 12 points, against 14 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am10 flights—
- 8am–11am57 flights75.4%
- 11am–2pm26 flights—
- 2pm–5pm69 flights63.2%
- 5pm–8pm1 flights—
- 8pm–5am295 flights72.7%
Scale runs 55% to 80%. Rows with fewer than 30 flights show a dash.
Book the morning departure. Flights leaving between 8am–11am arrive on time 75.4% of the time, against 63.2% for the afternoon window. That is 12 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8pm–5am window is the busiest, with 295 flights scheduled in it.
Across the year
Frontier on LAS to MCO through the year
June is the worst month at 51.9% on time, 36 points below October, the best at 87.9%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 57 flights.
Across the week, Wednesday is the strongest day at 82.5% on time and Sunday the weakest at 57.4%. 25 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 11,000 reported delay minutes.
- 41%Late-arriving aircraft
- 38%Carrier
- 13%National Airspace System
- 9%Extreme weather
41% 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 11,000 reported delay minutes here, that single category outweighs weather by 5 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 11,249 reported delay minutes.
The largest share of delay minutes, 38%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 4,304 of the 11,000 delay minutes reported here.
Cancellations are rare at 0.44%, 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
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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 81.4% on time across 461 flights, 10 points above 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. 458 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 MCO
Put together: treat all of this as provisional. 458 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 71.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 455 completed flights over 12 months sit behind that.
