Carrier by carrier

Frontier against every carrier on LAS to MCO

Frontier flew 478 of the 1,999 flights on LAS to MCO, about 24% of it. Its 67.4% on time is 7 points worse than the route as a whole, which runs 74.3%. Ranked by on-time rate it is number four of five carriers on the route, where the range runs from JetBlue at 84.1% 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 84.1% of the time; Southwest Airlines manages 73.1%. Sample sizes sit next to every figure, because a two-point gap across 1,006 flights means less than a ten-point one.

JetBlue leads Southwest by 11 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

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 20 points, against 11 points between the best and worst carrier.

5am–8am10 flights—
8am–11am79 flights68.4%
11am–2pm66 flights49.2%
2pm–5pm7 flights—
5pm–8pm1 flights—
8pm–5am315 flights69.4%

Scale runs 40% to 75%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 49.2% on time against 69.4% for 8pm–5am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8pm–5am window is the busiest, with 315 flights scheduled in it.

Across the year

Frontier on LAS to MCO through the year

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

July is the worst month at 44.3% on time, 44 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. July was the busiest month here, with 62 flights.

Across the week, Tuesday is the strongest day at 77.3% on time and Friday the weakest at 54.4%, a spread of 23 points.

Share of 472 completed flights by arrival against schedule.

24 of 152 late departures made up the time and arrived on time, 16% of them. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.

Delay causes

Why Frontier runs late on this route

Late-arriving aircraft accounts for 45% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
45%
Carrier
41%
National Airspace System

Extreme weather
2%

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 30 to one. The split is drawn from 13,652 reported delay minutes.

The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,630 of the 14,000 delay minutes reported here.

Cancellations sit at 1.26% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and stage length

What a delay here costs

12.9% 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 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 81.1% on time across 480 flights, 14 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 14 points of difference.

One caution: this is a thin sample. 478 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. 478 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 67.4% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 472 completed flights over 12 months sit behind that.
