Carrier by carrier

JetBlue against every carrier on ORD to FLL

JetBlue flew 107 of the 3,517 flights on ORD to FLL, about 3% of it. Its 70.1% on time is about level with the route as a whole at 70.8%. Ranked by on-time rate it is number two of six carriers on the route, where the range runs from United at 76.8% to Spirit at 61.9%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The choice of carrier is not cosmetic here. United Airlines arrives on time 76.8% of the time; Spirit Airlines manages 61.9%. Sample sizes sit next to every figure, because a two-point gap across 776 flights means less than a ten-point one.

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 26 points, against 15 points between the best and worst carrier.

5am–8am53 flights83.3%
8am–11am—
11am–2pm—
2pm–5pm54 flights57.1%
5pm–8pm—
8pm–5am—

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 83.3% of the time, against 57.1% for the afternoon window. That is 26 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 2pm–5pm window is the busiest, with 54 flights scheduled in it.

Across the year

JetBlue on ORD to FLL through the year

Jul–Sep 2026107 flights70.1%

Scale runs 60% to 75%.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 70.1% on time across 107 flights.

Split by quarter, JetBlue on ORD to FLL logged 107 flights in Jul–Sep 2026. Fewer than three of those quarters carried the 30 completed flights this site needs before printing a rate, so the 70.1% annual figure is the one to use.

Delay causes

Why JetBlue runs late on this route

Late-arriving aircraft accounts for 62% of the 2,248 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
62%
Carrier
23%
National Airspace System
15%
Extreme weather
1%

62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,248 reported delay minutes here, that single category outweighs weather by 62 to one. The split is drawn from 2,248 reported delay minutes.

The practical consequence: the 5am–8am 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 9.35%, against 1.89% nationally. That is about one flight in ten 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

12.4% 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 1,182 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 is a different operation and performs like one: it runs 62.6% on time across 108 flights, 7 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 7 points of difference.

One caution: this is a thin sample. 107 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 ORD to FLL

Put together: the delay figures matter less here than the 9.35% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 97 completed flights over 12 months sit behind that.
