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

JetBlue on BOS to DFW 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 231 flights. The strongest carrier on the route with a full sample, American Airlines, flew 2,633 at 78.0% on time.

The US average over the same twelve months is 77.6%, so there is little to separate JetBlue on BOS to DFW from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on BOS to DFW, 3,740 flights

These figures cover 231 flights between July 2025 and June 2026. Beyond the headline rate, 10.8% 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 BOS to DFW

JetBlue flew 231 of the 3,740 flights on BOS to DFW, about 6% of it. Its 78.4% on time is 2 points better than the route as a whole, which runs 76.1%. Ranked by on-time rate it is first of four carriers on the route, where the range runs from JetBlue at 78.4% to Delta at 70.0%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. American Airlines arrives on time 78.0% of the time; Delta Air Lines manages 70.0%. Sample sizes sit next to every figure, because a two-point gap across 861 flights means less than a ten-point one.

On-time performance by carrier on BOS to DFW
Airline	Flights	On time	Avg delay	Cancelled	Grade
JetBlue Airways (this page)thin sample	231	78.4%	77 min	3.46%	B−
American Airlines	2,633	78.0%	87 min	3.46%	B−

Delta Air Lines	861	70.0%	79 min	2.21%	C

American Airlines cancels 3.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

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 16 points, against 8 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am60 flights76.4%
8am–11am127 flights83.3%
11am–2pm1 flights—
2pm–5pm43 flights67.5%
5pm–8pm—
8pm–5am—

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

Book the morning departure. Flights leaving between 8am–11am arrive on time 83.3% of the time, against 67.5% for the afternoon window. That is 16 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 127 flights scheduled in it.

Across the year

JetBlue on BOS to DFW through the year

Jul–Sep 202588 flights81.6%

Scale runs 55% to 90%. 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 78.4% on time across 231 flights.

JetBlue on BOS to DFW did not run the same all year. Its best quarter was Oct–Dec 2025 at 82.8% on time and its weakest Jan–Mar 2026 at 64.6%, a swing of 18 points on roughly 77 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Across the week, Tuesday is the strongest day at 96.7% on time and Thursday the weakest at 67.6%. 29 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. Carrier accounts for 44% of the 3,705 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.

The largest share of delay minutes, 44%, 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 1,632 of the 3,705 delay minutes reported here. The split is drawn from 3,705 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 83.3% on time here.

Cancellations run at 3.46%, against 1.81% nationally. That is about one flight in 30 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. 10.8% 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 1,562 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 55.9% on time across 231 flights, 23 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 23 points of difference.

One caution: this is a thin sample. 231 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 BOS to DFW

Put together: the delay figures matter less here than the 3.46% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 222 completed flights over 12 months sit behind that.
