Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on JFK to LAS lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 1,375 flights. The strongest carrier on the route with a full sample, American Airlines, flew 460 at 84.0% on time.
Set against the rest of the country, JetBlue's JFK to LAS record is 5 points better than the US average of 77.6%. That gap is worth roughly 48 fewer late arrivals for every thousand flights.

Every carrier on JFK to LAS, 3,714 flights
These figures cover 1,375 flights between July 2025 and June 2026. The median arrival is 12 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 JFK to LAS
JetBlue flew 1,375 of the 3,714 flights on JFK to LAS, about 37% of it. Its 82.4% on time is 3 points better than the route as a whole, which runs 79.9%. Ranked by on-time rate it is number two of four carriers on the route, where the range runs from American at 84.0% to Frontier at 65.0%. One 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.

| Frontier Airlinesthin sample | 203 | 65.0% | 65 min | 1.48% | C |
No carrier stands out. American tops the table at 84.0%, 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 matters more here than the choice of carrier. The gap between the best and worst window is 25 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am334 flights93.9%
- 8am–11am312 flights84.6%
- 11am–2pm147 flights90.2%
- 2pm–5pm176 flights79.1%
- 5pm–8pm206 flights68.5%
- 8pm–5am200 flights70.7%
Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.9% of the time, against 68.5% for the evening window. That is 25 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 334 flights scheduled in it.
Across the year
JetBlue on JFK to LAS through the year
December is the weak month at 69.0% on time, against 86.8% in November. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. October was the busiest month here, with 141 flights.
Across the week, Friday is the strongest day at 86.9% on time and Sunday the weakest at 74.0%. 13 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 46% of the 15,000 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.
- 46%Late-arriving aircraft
- 29%National Airspace System
- 21%Carrier
- 3%Extreme weather
- 1%Security
46% 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 15,000 reported delay minutes here, that single category outweighs weather by 15 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 15,350 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 93.9% on time here.
Cancellations sit at 2.25% against a national 1.81%, which is ordinary. Diversions add another 0.36%.
Connections and stage length
What a delay here costs
6.8% 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 2,248 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 78.6% on time across 1,373 flights, 4 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 4 points of difference.
The sample behind these figures is 1,375 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 JetBlue on JFK to LAS
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 86.8% on time and December 69.0%, a swing of 18 points. If the dates move at all, move them out of December before you think about anything else. 1,339 completed flights over 12 months sit behind that.
