Against the 15 carriers FlyerIntel covers — all measured over the same period, from the same source — JetBlue ranks 14th of 15 for on-time arrivals, 12th for cancellations and 15th for arrivals more than an hour late. The full table is at the foot of this page.

Over the most recent 12 months (2025-08 to 2026-07) JetBlue arrived on time 72.2% of the time, against 75.3% in the 12 months before (2024-08 to 2025-07) — declining by 3.1 percentage points.

Why JetBlue cancels flights

Every cancellation carries a reason code the operating carrier filed with US DOT. July 2023 – July 2026.

JetBlue cancelled 16,335 of 745,492 scheduled flights — about 1 in every 46. The reason it filed most often was the air traffic system, 38.6% of the cancellations it coded — about 1 in every 118 scheduled flights.

Of 16,335 cancelled departures carrying a reason code.

What each reason means

The air traffic system1 in 118

Airport capacity, air traffic control flow programs, heavy traffic and ordinary bad weather. A system decision, not the airline’s.

6,305 cancellations, 38.6% of the total.

Extreme weather1 in 122

Conditions the carrier judged severe enough to stop the flight: a blizzard, a hurricane, a line of thunderstorms.

6,106 cancellations, 37.4% of the total.

The airline1 in 190

Crew, maintenance, aircraft cleaning, baggage or fueling: what BTS counts as within the carrier’s own control.

3,924 cancellations, 24.0% of the total.

Security—

A terminal evacuation, a security breach, screening equipment failure, or screening queues over 29 minutes.

0 cancellations, 0.0% of the total.

What these shares do not measure

A reason code is the operating carrier’s own filing. US DOT collects the reason the airline gave; it does not adjudicate it, and carriers differ in how they fill the form in. The split above describes what kind of disruption JetBlue records, not who was at fault when it happened, and it cannot be set against another airline’s split to decide which of the two is better run.

That is measurable rather than a disclaimer. Across the 15 carriers FlyerIntel publishes, the correlation between how much of its own canceling a carrier attributes to itself and how often it actually cancels is -0.46 — negative, which is the wrong sign for a ranking of fault and about the right sign for a difference in filing convention. Hawaiian Airlines attributed 82.8% of its cancellations to itself and cancelled 1.00% of its flights; SkyWest Airlines attributed 2.7% and cancelled 1.33%. The airline taking the most blame is the one that cancels least.

The figure on this page that does compare cleanly between airlines is the cancellation rate in Reliability, because it counts cancellations instead of reading the reason filed for them. The First Flight of the Day sets out the same finding from the airport-carrier records, and declines on the strength of it to compare any two carriers’ codes.

Ordinary bad weather is filed under air traffic, so weather’s full share is larger than its bar.

Shares are of JetBlue’s own coded cancellations at each airport and run across the row, so they total 100%. “Rate” is cancellations as a share of its scheduled departures there. Reading down a column compares one airline with itself in different weather and different airspace, which is the comparison these codes support — a carrier files the same way wherever it flies, so its filing habits largely cancel out of the differences between these rows in a way they never cancel out of a comparison between two airlines. Airports where JetBlue recorded fewer coded cancellations than the published minimum are not listed.

Source: US DOT Bureau of Transportation Statistics · Data covering July 2023 – July 2026 · These are the reason codes JetBlue itself filed with US DOT — the reason the airline gave, not an independent finding of fault, and airlines differ in how they apply them. FlyerIntel publishes the split only for carriers with at least 500 coded cancellations in the period; 16,335 were recorded. Whatever the reason code, a cancelled flight may qualify for an automatic refund under DOT’s rule — the refund checker covers eligibility.

Each column is one month of JetBlue operations. The strongest single month of the period was October 2024 at 85.8% on time; the weakest was July 2023 at 53.6%. Individual months move for reasons that do not repeat — a hurricane season, a technology outage, a winter storm — which is why the section below combines the same data by calendar month instead.

December	62,729	68.5%	1.41%

Combining 3 to 4 years of operations by calendar month, JetBlue is at its best in November, when 78.8% of arrivals were on time, and at its worst in July at 62.6% — a spread of 16.2 percentage points between two months of the same airline. Cancellations peak in the same month: July at 5.88% of flights, against 0.40% in May.

This is the shape of the calendar, not a forecast. It says that if you book JetBlue in July you are booking into the part of the year when this airline has historically been least punctual, and that a November itinerary starts from a better position. It does not say anything about a particular date, and it cannot: the figure behind each month is 3 to 4 years of that same month combined, precisely so that one storm does not decide the answer.

Best time to fly JetBlue

How JetBlue departures have done at each hour of each weekday, across its whole network.

By day and hour

On-time arrival rate for each weekday and scheduled departure hour, in local time at the airport each flight leaves from, so the grid mixes time zones across the network.

Wednesday 6–7 AM was the most reliable slot for JetBlue (89.1% on time, 9,334 flights) and Sunday 5–6 PM the least (53.8%, 6,083 flights).

Hour of departure matters more than day of the week: hourly averages sit a typical 9.4 points from the network-wide rate, weekday averages 3.2 points.

Share of the delay minutes US DOT attributed to each cause for JetBlue. Only delays of 15 minutes or more are attributed.

The largest single category for JetBlue is late-arriving aircraft, at 41.0% of attributed minutes. The category squarely inside the carrier’s own control — crew, maintenance, boarding, fueling — accounts for 34.2% of its delay minutes, against 33.9% across the 15 carriers covered here.

These shares describe how delay minutes were divided, not how often delays happened. A carrier with an unusually large air-traffic-control share is not necessarily worse run; it may simply fly more of its schedule through congested airspace. The one category that is squarely the airline’s own is the carrier category, which is why it is the one compared above.

How JetBlue handles bad weather

Departures by the weather at the origin in the hour they were scheduled to leave, July 2023 – July 2026.

10% of JetBlue’s weather-matched departures left in an hour of bad weather at the origin. 5.1% of them were cancelled, 2.9 times the 1.8% cancelled in normal hours, and 60.6% of those that flew arrived on time, against 73.5%. Those hours held 23% of the airline’s cancelled departures.

In bad weather JetBlue cancelled about as many flights as the other carriers: 5.2% of its departures in those hours were cancelled, against 5.1% for the other carriers at the same airports in the same months. In normal hours it was above them (1.8% against 1.4%). Its flights that operated arrived on time 60.5% of the time, 5.7 points below the others’ 66.2%.

Bad-weather hours against normal hours

Scheduled departures, July 2023 – July 2026

JetBlue cancellation and on-time rates in bad-weather and normal hours at the origin, with the other carriers at the same airports and months

Other carriers	61,638compared	5.1%	66.2%

Bad weather means IFR or LIFR conditions, or a storm, snow, ice, fog, heavy rain or high wind, at the origin; normal means VFR with none of those. Marginal hours are in neither row, and were 8% of JetBlue’s matched departures. Cancelled is the share of scheduled departures. The other carriers’ rows apply their rate in each airport and month to the departures JetBlue had there.

The most exposed airports were LGA (6.9% of 3,007), TPA (6.7% of 1,214), EWR (6.6% of 2,326); the least, LAX (1.0% of 2,801), SFO (1.3% of 1,072), SJU (1.3% of 689). The widest gap above the other carriers was at PIT, Pittsburgh: 6.5% cancelled against 3.1%. The widest below them was at DCA, Washington: 6.1% cancelled against 8.8%.

SJU San Juan	689	1.3%	—	1.5%

Airports are listed with at least 500 of JetBlue’s bad-weather departures and 500 weather-matched departures in all. Other carriers is their cancellation rate in the same airport and months, applied to JetBlue’s departures there, and is left blank where JetBlue was nearly the only carrier flying in the bad-weather hours of most months and there is no one to compare with.

This is the weather reported at the origin in the hour a flight was scheduled to leave, July 2023 – July 2026. It leaves out the weather at the destination and on the way, and an hour takes the worst conditions any report in it gave. Weather was matched to 85.4% of JetBlue’s scheduled departures: the rest left from airports with no archived weather, in hours with no report, or at a scheduled time the flight records cannot place exactly. The comparison covers 1,161 airport-months in which JetBlue flew in bad weather; the other carriers are held to the same airport and calendar month, not the same hour of the day or the same aircraft, so a carrier that schedules more of those departures at the busiest or the quietest times is not fully adjusted for. 1,292 of its bad-weather departures were in an airport and month where the other carriers had fewer than 120 of their own, and are not in that comparison.

Turning aircraft around at JetBlue

Time on the ground between one flight and the next of the same aircraft, and what a late arrival does to the next departure, July 2023 – July 2026.

The median JetBlue turn is scheduled for 59 minutes on the ground and takes 69 minutes, against 56 minutes and 63 minutes across all airlines. JetBlue gives its aircraft longer on the ground than the network does. 24.5% of its turns began with an aircraft that landed 15 or more minutes late, against 18.9% for the network.

When the aircraft landed 15 or more minutes late (120,414 turns, 66 minutes late on average), 60% of the turns were finished in no more than the scheduled ground time, against 68% across all airlines. 77% of those flights left 15 or more minutes late, against 72%. After an aircraft that landed on time, 14% did (network 11%).

Given the turn lengths it schedules, the network’s rates would give 70% finished in the schedule and 70% leaving late. By that measure JetBlue finished fewer late turns in the schedule and passed lateness on to the next departure more often than the network would have. 45% of its late-inbound turns had a scheduled turn of 45 to 59 minutes, against 31% of the network’s.

Turns, JetBlue against the network

492,439 turns, July 2023 – July 2026

JetBlue aircraft turns against all airlines: scheduled and actual time on the ground and what a late inbound aircraft does
Measure	JetBlue	All airlines	All airlines, same turn lengths
Median scheduled turn	59 min	56 min	—
Median actual turn	69 min	63 min	—
Turns that began with an aircraft 15+ minutes late	24%	19%	—
Late turns finished within the schedule	60%	68%	70%
Late inbound that left 15+ minutes late	77%	72%	70%
On-time inbound that left 15+ minutes late	14%	11%	—

Late means 15 or more minutes. A turn finishes within the schedule when the aircraft spent no more time on the ground than the schedule gave it. The last column applies the network’s rate in each scheduled-turn band (under 30 minutes up to 3 to 6 hours) to the number of JetBlue turns in that band, so it shows what the same turn lengths would give across all airlines.

A turn pairs an aircraft’s landing with its next departure by tail number; the aircraft is never named. These 492,439 turns are 66% of JetBlue’s flights in the period; the rest are an aircraft’s first flight after a long stay, flights without a usable inbound, and cancelled flights. Ground time is measured from the gate: the scheduled turn plus the departing flight’s delay minus the inbound’s arrival delay. Overnight stays (6 hours or more on the ground), cancelled flights and flights whose inbound diverted are not turns here. Turns scheduled under 30 minutes are a small share and are kept, but they are rarely a plan for that aircraft (more often a swap or recovery, with the flight waiting for an aircraft that was not the one scheduled), so most of them across the network leave late even after an on-time landing. A flight that an airline covered with a different aircraft is linked to the one that flew it, not the one first planned.

“Elsewhere” is every other covered airline together, from the same aggregates as this page. Hours and months appear only where both sides have at least 120 completed flights; airports only where JetBlue and everyone else there each have at least 500. Gaps must be at least 2 points and 2 standard errors, and only the largest in each direction is shown. Airlines fly different airports, so the hour and month rows partly compare different traffic; the airport rows compare like with like. The taxi figure is weighted by departures, mixes airports, and has no error estimate, so it appears from 2 minutes.

JetBlue departed from 82 airports in this period, with no single one accounting for more than 16.6% of departures and the largest three together 40.0%. Performance is spread across the network rather than resting on one or two hubs, so a single weak airport moves this carrier’s overall figure less than it would at a hub-and-spoke airline.

July 2023 – July 2026. Airports need at least 2,000 completed flights by JetBlue, routes 600. The other airlines are everyone else at the same airport or on the same route, compared only where they have at least 500 (airports) or 200 (routes) completed flights; a gap counts as ahead or behind only at 2 points and 2 standard errors. Route figures are for one direction. Airlines fly different times of day and aircraft, so a gap is a comparison, not a cause.

301 JetBlue flight numbers have operated their current route at least 600 times. The strongest of them, B61233 from Orlando to San Juan, arrived on time 91.8% of the time. The weakest, B6998 from Orlando to New York, managed 51.1% — a gap of 41 percentage points inside one airline. The departures in the first column are scheduled to leave at a median of 7:00 AM; those in the second at 6:00 PM.

Choosing between two flights on the same airline and the same day is a decision most travelers make on price and timing alone, because nothing at the point of booking distinguishes them. These figures do. They are the record of the exact flight number, on the route it flies today, over the whole analysis period — not a carrier average applied to it.

Source: FlyerIntel analysis of US DOT BTS data · July 2023 – July 2026 · A flight number is a slot in a schedule and gets reassigned to different city pairs over time, so each is measured only on the route it currently operates. Numbers with fewer than 600 operations on that route, or last flown more than a quarter ago, are not ranked. Schedules change — confirm a departure still operates before booking around it.

Every carrier on FlyerIntel is measured the same way, over the same period, using the same source data. That is the whole point of the table: airline marketing reports punctuality on definitions of its own choosing, and this does not.

Data and methodology

Calculated by FlyerIntel from 745,492 JetBlue flight records published by the US DOT Bureau of Transportation Statistics, covering July 2023 – July 2026. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately, because folding them in would flatter a carrier that cancels rather than runs late. Figures below a published sample threshold are omitted rather than shown with a caveat.
