Every carrier on LAS to MCO, 1,999 flights
These figures cover 1,006 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Carrier by carrier
Southwest against every carrier on LAS to MCO
Southwest flew 1,006 of the 1,999 flights on LAS to MCO, most of the route. Its 73.1% on time is about level with the route as a whole at 74.3%. Ranked by on-time rate it is number three 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; Frontier Airlines manages 67.4%. Sample sizes sit next to every figure, because a two-point gap across 478 flights means less than a ten-point one.

Scale runs 30% to 90%.
The overnight block holds up unusually well at 85.5% on time across 365 flights. Red-eyes fly into empty airspace and empty gates, and they are the first rotation of the aircraft's day rather than the last. The 8pm–5am window is the busiest, with 365 flights scheduled in it.

Southwest on LAS to MCO through the year

Share of 997 completed flights by arrival against schedule.
89 of 303 late departures made up the time and arrived on time, 29% of them. In the other direction, 54 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.
The worst days
Worst days for Southwest on LAS to MCO
The latest arrival of the period was on 24 June 2026, 4 hours 24 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 24 June 2026 | 4 hours 24 minutes | Late-arriving aircraft |
| 22 August 2026 | 4 hours 14 minutes | Carrier |
| 1 August 2026 | 4 hours 2 minutes | Carrier |
| 12 October 2025 | 3 hours 20 minutes | Late-arriving aircraft |

Delay causes
Why Southwest runs late on this route
Carrier accounts for 52% of the 12,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Carrier
- 28%Late-arriving aircraft
- 17%National Airspace System
- 3%Extreme weather
The largest share of delay minutes, 52%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 6,264 of the 12,000 delay minutes reported here. The split is drawn from 11,951 reported delay minutes.
Cancellations are rare at 0.20%, below the national 1.89% 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
5.8% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 45 minutes, 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 77.2% on time across 960 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 1,006 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 Southwest on LAS to MCO
Put together: treat all of this as provisional. 1,006 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 73.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 997 completed flights over 12 months sit behind that.
