Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on LAS to JFK lands a B, about a point better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 1,373 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,676 at 84.2% on time.
The US average over the same twelve months is 77.6%, so there is little to separate JetBlue on LAS to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on LAS to JFK, 3,710 flights
These figures cover 1,373 flights between July 2025 and June 2026. Beyond the headline rate, 8.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
JetBlue against every carrier on LAS to JFK
JetBlue flew 1,373 of the 3,710 flights on LAS to JFK, about 37% of it. Its 78.6% on time is 3 points worse than the route as a whole, which runs 81.3%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Delta at 84.2% to American at 78.6%. 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.

| Delta Air Lines | 1,676 | 84.2% | 78 min | 2.45% | B |
| Frontier Airlinesthin sample | 202 | 81.5% | 57 min | 0.99% | B+ |

| American Airlines | 459 | 78.6% | 107 min | 1.74% | B |
No carrier stands out. Delta tops the table at 84.2%, 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 12 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am218 flights86.3%
- 8am–11am249 flights85.5%
- 11am–2pm272 flights76.1%
- 2pm–5pm190 flights74.1%
- 5pm–8pm—
- 8pm–5am444 flights74.5%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 86.3% of the time, against 74.1% for the afternoon window. That is 12 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 444 flights scheduled in it.
Across the year
JetBlue on LAS to JFK through the year
November is the best month on the calendar at 88.7% on time. Shoulder season thins the schedule and takes the summer weather with it, and the operation gets its margin back. October was the busiest month here, with 140 flights.
Across the week, Wednesday is the strongest day at 83.7% on time and Sunday the weakest at 71.9%. 12 points is a smaller lever than departure hour, but it is free.
Delay causes
Why JetBlue runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 26,000 reported delay minutes.
- 40%Carrier
- 32%Late-arriving aircraft
- 26%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 10,000 of the 26,000 delay minutes reported here. The split is drawn from 26,191 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 86.3% on time here.
Cancellations run at 2.77%, against 1.81% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
8.9% 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 an hour and a half, 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 82.4% on time across 1,375 flights, 4 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 4 points of difference.
The sample behind these figures is 1,373 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 LAS to JFK
Put together: the calendar is the biggest lever here, not the carrier or the hour. November runs 88.7% on time and March 66.4%, a swing of 22 points. If the dates move at all, move them out of March before you think about anything else. 1,325 completed flights over 12 months sit behind that.
