These figures cover 470 flights between September 2025 and August 2026. The median arrival is 20 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 470 of the 1,955 flights on MCO to LAS, about 24% of it. Its 90.2% on time is 9 points better than the route as a whole, which runs 81.3%. Ranked by on-time rate it is first of five carriers on the route, where the range runs from JetBlue at 90.2% to Delta at 66.7%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The two carriers here are closely matched: 4 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 470 flights.
- 5am–8am81 flights87.7%
- 8am–11am224 flights94.6%
- 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 94.6% of the time, against 85.5% for the overnight window. That is 9 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 224 flights scheduled in it.

The worst days
Worst days for JetBlue on MCO to LAS
The latest arrival of the period was on 20 July 2026, 3 hours 34 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across July, February, March and January, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 20 July 2026 | 3 hours 34 minutes | Late-arriving aircraft |
| 27 February 2026 | 3 hours 21 minutes | Late-arriving aircraft |
| 9 March 2026 | 2 hours 57 minutes | Carrier |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 48% of the 3,079 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Late-arriving aircraft
- 26%Carrier
- 25%National Airspace System
- 1%Extreme weather
48% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,079 reported delay minutes here, that single category outweighs weather by 34 to one. The split is drawn from 3,079 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 94.6% on time here.
Cancellations are rare at 0.21%, 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
Badly late arrivals are rare here: only 4.3% land an hour or more behind schedule, against 8.3% 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 is a different operation and performs like one: it runs 84.1% on time across 470 flights, 6 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 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 MCO to LAS
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 90.2% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 469 completed flights over 12 months sit behind that.
