These figures cover 1,955 flights between September 2025 and August 2026. The median arrival is 10 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
Which airline is most reliable on MCO to LAS
The choice of carrier is not cosmetic here. JetBlue Airways arrives on time 90.2% of the time; Southwest Airlines manages 77.2%. Sample sizes sit next to every figure, because a two-point gap across 960 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| JetBlue Airways | 470 | 90.2% | 67 min | 0.21% | A+ |
| Frontier Airlines | 480 | 81.1% | 81 min | 1.46% | B |
| Southwest Airlines | 960 | 77.2% | 53 min | 0.00% | B+ |

| Delta Air Linesthin sample | 3 | 66.7% | 19 min | 0.00% | C+ |
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.

Best ways to make this trip
The most reliable ways to fly Orlando to Las Vegas
Every airline on this route, ranked by how often a scheduled flight actually operated and arrived on time, with its best departure time and most punctual flight number. No nearby airport pair beat these.
| Option | Airline | Success | On time | Cancelled | Best departure | Most punctual flight |
|---|---|---|---|---|---|---|
| 1. MCO → LASOrlando to Las Vegas | JetBlue Airways | 90.0% | 90.2% | 0.21% | 8am–11am, Wed | B6 2821 08:00 |

Success is the share of scheduled flights that operated and arrived less than 15 minutes late, so a cancelled flight counts against it. “(route)” means the best time comes from every carrier on the route rather than this airline alone.
Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 29 points, against 13 points between the best and worst carrier.

- 8am–11am545 flights91.7%

Scale runs 55% to 100%.
The 5pm–8pm window is where this operation falls apart: 63.6% on time, against 92.6% 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 545 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 17 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
November is the best month on the calendar at 91.5% 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 209 flights.
Across the week, Wednesday is the strongest day at 89.2% on time and Monday the weakest at 76.4%, a spread of 13 points.
Delay causes
Why this route gets delayed
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 22,000 reported delay minutes.
- 40%Late-arriving aircraft
- 28%Carrier
- 21%National Airspace System
- 10%Extreme weather
- 1%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 22,000 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 22,392 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 92.6% on time here.
Cancellations are rare at 0.41%, 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 actually costs
6.0% 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 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 74.3% on time across 1,999 flights, 7 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 7 points of difference.
The sample behind these figures is 1,955 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this
Booking this route
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 91.5% on time and October 74.2%, a swing of 17 points. If the dates move at all, move them out of October before you think about anything else. 1,944 completed flights over 12 months sit behind that.
Common questions
MCO to LAS questions
How often is MCO to LAS delayed?
About one flight in five arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 18.7% of the 1,955 flights in this analysis, against 22.7% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on MCO to LAS?
JetBlue Airways leads at 90.2% on time across 470 flights. Southwest Airlines is at the other end on 77.2%, a gap of 13 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on MCO to LAS?
The 5am–8am departure window is the strongest at 92.6% on time. The 5pm–8pm window is the weakest at 63.6%, 29 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are October delays on MCO to LAS?
October is the weakest month at 74.2% on time, compared with 91.5% in November. Across the year that is 17 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
