Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with JetBlue Airways.

JetBlue on LAS to EWR 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 a little over an hour on average. That is a workable record, not a spotless one. That rests on 311 flights, with a median arrival 9 minutes early.

The US average over the same twelve months is 77.6%, so there is little to separate JetBlue on LAS to EWR 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 EWR, 2,990 flights

These figures cover 311 flights between July 2025 and June 2026. Beyond the headline rate, 9.3% 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 EWR

JetBlue flew 311 of the 2,990 flights on LAS to EWR, about 10% of it. Its 78.8% on time is 3 points worse than the route as a whole, which runs 81.4%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 82.0% to Spirit at 77.6%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

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 311 flights.

8am–11am132 flights77.8%
11am–2pm8 flights—

Scale runs 70% to 85%. Rows with fewer than 30 flights show a dash.

The 8pm–5am window is the strongest at 78.6% on time. The full set of windows spans about a point.

Across the year

JetBlue on LAS to EWR through the year

Jan–Mar 2026172 flights76.7%
Apr–Jun 2026139 flights81.3%

Scale runs 70% to 85%. Rows with fewer than 30 flights show a dash.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 78.8% on time across 311 flights.

Split by quarter, JetBlue on LAS to EWR logged 172 flights in Jan–Mar 2026 and 139 flights in Apr–Jun 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 78.8% annual figure is the one to use.

Across the week, Saturday is the strongest day at 87.8% on time and Tuesday the weakest at 69.6%. 18 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 4,567 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.

Late-arriving aircraft
44%
National Airspace System
29%
Carrier
27%

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 4,567 reported delay minutes here, that single category outweighs weather by 44 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 4,567 reported delay minutes.

Cancellations run at 2.57%, against 1.81% nationally. That is about 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.3% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

At 2,227 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 76.5% on time across 311 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. 311 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 EWR

Put together: treat all of this as provisional. 311 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 78.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 302 completed flights over 12 months sit behind that.
