This route sits in the middle of the pack with a B+. Close to three flights in four arrive on time by the DOT's definition, 2 points worse than the national rate of 77.6%. The late ones land about an hour behind schedule. That rests on 1,906 LAS to MCO flights, of which JetBlue Airways flew 408 at 87.5% on time.
Best time to fly LAS to MCO: a 5am–8am departure, ideally on a Wednesday. Flights in that window arrived on time 81.7% of the time and Wednesday flights 82.5%, against 75.5% for the route overall.
JetBlue Airways is the most reliable of the three carriers covered here at 87.5% on time across 408 flights.

87.5% on time across 408 flights
These figures cover 1,906 flights between July 2025 and June 2026. The median arrival is 3 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 LAS to MCO
The choice of carrier is not cosmetic here. JetBlue Airways arrives on time 87.5% of the time; Frontier Airlines manages 71.6%. Sample sizes sit next to every figure, because a two-point gap across 458 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| JetBlue Airways | 408 | 87.5% | 69 min | 0.00% | A+ |
| Southwest Airlines | 940 | 73.3% | 40 min | 0.21% | C+ |
| Frontier Airlines | 458 | 71.6% | 87 min | 0.44% | C+ |
| Spirit Airlinesthin sample | 97 | 64.9% | 64 min | 0.00% | D+ |
| Delta Air Linesthin sample | 3 | 33.3% | 31 min | 0.00% | F+ |
The spread between JetBlue and Frontier is 16 points, wide enough that it should decide the booking. On a hundred trips that is 16 more arrivals inside the on-time window.

Best ways to make this trip
The most reliable ways to fly Las Vegas to Orlando
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. LAS → MCOLas Vegas to Orlando | JetBlue Airways | 87.5% | 87.5% | 0.00% | 2pm–5pm, Wed | — |
| 2. LAS → MCOLas Vegas to Orlando | Southwest Airlines | 73.1% | 73.3% | 0.21% | 8pm–5am, Tue | — |
| 3. LAS → MCOLas Vegas to Orlando | Frontier Airlines | 71.3% | 71.6% | 0.44% | 8am–11am, Wed | F9 1876 23:00 |
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 19 points, against 16 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am188 flights81.7%
- 8am–11am266 flights74.8%
- 11am–2pm365 flights71.5%
- 2pm–5pm202 flights62.7%
- 5pm–8pm19 flights—
- 8pm–5am866 flights79.4%
Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 81.7% of the time, against 62.7% for the afternoon window. That is 19 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 866 flights scheduled in it.
Across the year
When delays peak on this route
This route's year swings by 26 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.
August is the worst month at 62.5% on time, 26 points below November, the best at 88.8%. 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 210 flights.
Across the week, Wednesday is the strongest day at 82.5% on time and Sunday the weakest at 68.4%. 14 points is a smaller lever than departure hour, but it is free.
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 27,000 reported delay minutes.
- 39%Late-arriving aircraft
- 39%Carrier
- 18%National Airspace System
- 5%Extreme weather
39% 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 27,000 reported delay minutes here, that single category outweighs weather by 8 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 26,927 reported delay minutes.
The largest share of delay minutes, 39%, 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 10,000 of the 27,000 delay minutes reported here.
Cancellations are rare at 0.21%, 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 actually costs
6.7% 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 79.6% on time across 1,900 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.
The sample behind these figures is 1,906 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 88.8% on time and August 62.5%, a swing of 26 points. If the dates move at all, move them out of August before you think about anything else. 1,897 completed flights over 12 months sit behind that.
Common questions
LAS to MCO questions
How often is LAS to MCO delayed?
About one flight in four arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 24.5% of the 1,906 flights in this analysis, against 22.4% nationally. Delayed flights are late by about an hour on average.
Which airline is most reliable on LAS to MCO?
JetBlue Airways leads at 87.5% on time across 408 flights. Frontier Airlines is at the other end on 71.6%, a gap of 16 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 LAS to MCO?
The 5am–8am departure window is the strongest at 81.7% on time. The 2pm–5pm window is the weakest at 62.7%, 19 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 August delays on LAS to MCO?
August is the weakest month at 62.5% on time, compared with 88.8% in November. Across the year that is 26 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
