JetBlue on MCO to LAS earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 12 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 408 flights. The strongest carrier on the route with a full sample, Frontier Airlines, flew 461 at 81.4% on time.

Set against the rest of the country, JetBlue's MCO to LAS record is 12 points better than the US average of 77.6%. That gap is worth roughly 116 fewer late arrivals for every thousand flights.

Every carrier on MCO to LAS, 1,900 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 MCO to LAS

JetBlue flew 408 of the 1,900 flights on MCO to LAS, about 21% of it. Its 89.2% on time is 10 points better than the route as a whole, which runs 79.6%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from JetBlue at 89.2% to Spirit at 66.3%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 6 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.

No carrier stands out. Frontier tops the table at 81.4%, 6 points clear of the bottom, which is inside the range this kind of sample moves year to year.

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–8am81 flights87.7%
8am–11am162 flights93.8%
11am–2pm—
2pm–5pm—
5pm–8pm—
8pm–5am165 flights85.5%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 93.8% of the time, against 85.5% for the overnight window. That is 8 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 165 flights scheduled in it.

Across the year

JetBlue on MCO to LAS through the year

Darker means more delays. Figures are on-time percentages.May best, March worst

May is the best month on the calendar at 100.0% 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 93.0% on time and Friday the weakest at 84.5%. 9 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 44% of the 2,832 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.

44% 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 2,832 reported delay minutes here, that single category outweighs weather by 29 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 2,832 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.8% on time here.

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

Badly late arrivals are rare here: only 4.7% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 87.5% 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 MCO to LAS

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 89.2% 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.
