Carrier by carrier
JetBlue against every carrier on FLL to ORD
JetBlue flew 108 of the 3,518 flights on FLL to ORD, about 3% of it. Its 62.6% on time is 6 points worse than the route as a whole, which runs 68.7%. Ranked by on-time rate it is number four of six carriers on the route, where the range runs from United at 74.6% to Southwest at 38.7%. 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 74.6% of the time; Spirit Airlines manages 57.7%. Sample sizes sit next to every figure, because a two-point gap across 775 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 20 points, against 17 points between the best and worst carrier.
- 5am–8am—
- 8am–11am—
- 11am–2pm54 flights72.5%
- 2pm–5pm—
- 5pm–8pm—
- 8pm–5am54 flights52.1%
Scale runs 45% to 80%. Rows with fewer than 30 flights show a dash.
The 8pm–5am window is where this operation falls apart: 52.1% on time, against 72.5% 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 11am–2pm window is the busiest, with 54 flights scheduled in it.
Across the year
JetBlue on FLL to ORD through the year
- Jul–Sep 2026108 flights62.6%
Scale runs 55% to 70%.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 62.6% on time across 108 flights.
Split by quarter, JetBlue on FLL to ORD logged 108 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 62.6% annual figure is the one to use.
Delay causes
Why JetBlue runs late on this route
Carrier accounts for 50% of the 2,679 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 30%Late-arriving aircraft
- 20%National Airspace System
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,348 of the 2,679 delay minutes reported here. The split is drawn from 2,679 reported delay minutes.
Cancellations run at 4.63%, against 1.89% nationally. That is about one flight in twenty 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
17.2% 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 70.1% on time across 107 flights, 7 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 7 points of difference.
One caution: this is a thin sample. 108 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 FLL to ORD
Put together: the delay figures matter less here than the 4.63% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 99 completed flights over 12 months sit behind that.
