Every carrier on LAS to MCO, 1,999 flights

These figures cover 470 flights between September 2025 and August 2026. The median arrival is 14 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 470 of the 1,999 flights on LAS to MCO, about 24% of it. Its 84.1% on time is 10 points better than the route as a whole, which runs 74.3%. Ranked by on-time rate it is first 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 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.

Departure window

When JetBlue runs best on this route

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 15 points, against 6 points between the best and worst carrier.

5am–8am—
8am–11am1 flights—
11am–2pm186 flights88.7%
2pm–5pm118 flights74.1%
5pm–8pm—
8pm–5am165 flights85.5%

Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.

The best window here is not the first bank but the 11am–2pm slot at 88.7% on time, ahead of 2pm–5pm at 74.1%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 11am–2pm window is the busiest, with 186 flights scheduled in it.

Across the year

Delay causes

Why JetBlue runs late on this route

Late-arriving aircraft accounts for 56% of the 4,792 delay minutes carriers reported here, and the remaining four split what is left.

56%

56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,792 reported delay minutes here, that single category outweighs weather by 56 to one. The split is drawn from 4,792 reported delay minutes.

Cancellations are rare at 0.43%, 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

6.5% 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 90.2% on time across 470 flights, 6 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 6 points of difference.

One caution: this is a thin sample. 470 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. 470 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 84.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 464 completed flights over 12 months sit behind that.
