Every carrier on LAS to MCO, 1,906 flights
These figures cover 408 flights between July 2025 and June 2026. The median arrival is 18 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
JetBlue against every carrier on LAS to MCO
JetBlue flew 408 of the 1,906 flights on LAS to MCO, about 21% of it. Its 87.5% on time is 12 points better than the route as a whole, which runs 75.5%. Ranked by on-time rate it is first 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 two carriers here are closely matched: 2 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

Departure window
When JetBlue runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 408 flights.
- 5am–8am—
- 8am–11am1 flights—
- 11am–2pm186 flights88.7%
- 2pm–5pm56 flights89.3%
- 5pm–8pm—
- 8pm–5am165 flights85.5%
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The 2pm–5pm window is the strongest at 89.3% on time. The full set of windows spans 4 points.
Across the year
JetBlue on LAS to MCO through the year
May is the best month on the calendar at 93.5% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. January was the busiest month here, with 62 flights.
Across the week, Wednesday is the strongest day at 94.7% on time and Tuesday the weakest at 82.8%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why JetBlue runs late on this route
One category carries most of the weight here. Late-arriving aircraft accounts for 61% of the 3,493 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 61%Late-arriving aircraft
- 29%Carrier
- 10%National Airspace System
- 1%Extreme weather
61% 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 3,493 reported delay minutes here, that single category outweighs weather by 61 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 3,493 reported delay minutes.
Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
5.6% 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 a little over 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 runs 89.2% on time across 408 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 408 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 JetBlue on LAS to MCO
Put together: treat all of this as provisional. 408 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 87.5% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 408 completed flights over 12 months sit behind that.
