These figures cover 674 flights between July 2025 and June 2026. Beyond the headline rate, 10.5% 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 PHL to FLL
JetBlue flew 674 of the 3,411 flights on PHL to FLL, about 20% of it. Its 70.1% on time is 3 points worse than the route as a whole, which runs 73.0%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from American at 75.9% to Spirit at 69.5%.
The choice of carrier is not cosmetic here. American Airlines arrives on time 75.9% of the time; Spirit Airlines manages 69.5%. Sample sizes sit next to every figure, because a two-point gap across 709 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| American Airlines | 1,449 | 75.9% | 74 min | 2.62% | B |
| Frontier Airlines | 579 | 73.1% | 81 min | 1.73% | C |
| JetBlue Airways (this page) | 674 | 70.1% | 75 min | 2.08% | C |
| Spirit Airlines | 709 | 69.5% | 69 min | 5.22% | C− |
Spirit Airlines cancels 5.2% 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 15 points, against 6 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am246 flights72.7%
- 8am–11am—
- 11am–2pm208 flights75.5%
- 2pm–5pm39 flights63.2%
- 5pm–8pm79 flights60.8%
- 8pm–5am102 flights63.0%
Scale runs 50% to 80%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 60.8% on time, against 75.5% for the 11am–2pm slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 246 flights scheduled in it.
Across the year
JetBlue on PHL to FLL through the year
January is the weak month at 52.2% on time, against 91.7% in October. 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. August was the busiest month here, with 62 flights.
Across the week, Wednesday is the strongest day at 81.2% on time and Sunday the weakest at 55.2%. 26 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 15,000 reported delay minutes.
- 37%Late-arriving aircraft
- 28%Carrier
- 26%National Airspace System
- 10%Extreme weather
37% 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 4 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 14,700 reported delay minutes.
Cancellations sit at 2.08% against a national 1.81%, which is ordinary. Diversions add another 0.74%.
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. 10.5% 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.
The 993 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The return leg is a different operation and performs like one: it runs 73.8% on time across 675 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.
One caution: this is a thin sample. 674 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 PHL to FLL
Put together: treat all of this as provisional. 674 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 70.1% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 655 completed flights over 12 months sit behind that.
