Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with JetBlue Airways.
JetBlue on PHL to FLL carries a cancellation problem, not just a delay problem: 3.3% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 730 flights. The strongest carrier on the route with a full sample, American Airlines, flew 1,628 at 75.4% on time.
American Airlines is the most reliable of the three carriers covered here at 75.4% on time across 1,628 flights.

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 23 points, against 6 points between the best and worst carrier.
- 5am–8am312 flights74.1%
- 8am–11am49 flights80.4%
- 11am–2pm148 flights75.4%

Scale runs 50% to 85%.
The 5pm–8pm window is where this operation falls apart: 57.7% on time, against 80.4% for the 8am–11am 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 312 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 93 flights.
Across the week, Wednesday is the strongest day at 79.8% on time and Sunday the weakest at 62.5%, a spread of 17 points.

Share of 702 completed flights by arrival against schedule.
36 of 175 late departures made up the time and arrived on time, 21% of them. In the other direction, 65 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at FLL.

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 16,000 reported delay minutes.
- 35%Late-arriving aircraft
- 34%Carrier
- 23%National Airspace System
- 8%Extreme weather
35% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 4 to one. The split is drawn from 16,239 reported delay minutes.
The largest share of delay minutes, 34%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,547 of the 16,000 delay minutes reported here.
Cancellations run at 3.29%, against 1.89% 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
10.7% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
The return leg runs 69.0% on time across 732 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. 730 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: the delay figures matter less here than the 3.29% 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. 702 completed flights over 12 months sit behind that.
