JetBlue on FLL to BWI earns an F−, which is as low as this site's scale goes for a reason. Only 47.1% of flights arrive inside the 15-minute window, 30 points worse than the national rate of 77.3%. Late arrivals average an hour and a half. Treat any tight connection here as a coin flip. That rests on 162 flights. The strongest carrier on the route with a full sample, Southwest Airlines, flew 2,106 at 73.5% on time.

The national on-time rate over the same period is 77.3%, so JetBlue on FLL to BWI runs 30 points behind the country as a whole. Across a thousand flights that is about 302 extra late arrivals.

Carrier by carrier

JetBlue against every carrier on FLL to BWI

JetBlue flew 162 of the 3,150 flights on FLL to BWI, about 5% of it. Its 47.1% on time is 24 points worse than the route as a whole, which runs 71.0%. Ranked by on-time rate it is last of four carriers on the route, where the range runs from Southwest at 73.5% to JetBlue at 47.1%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 3 points separate the best from the worst. At that spread, schedule and price are better tie-breakers than reliability. Sample sizes are shown so you can see which rows are worth weighing.

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 18 points, against 3 points between the best and worst carrier.

5am–8am—
8am–11am—
11am–2pm54 flights51.9%
2pm–5pm—
5pm–8pm54 flights35.4%
8pm–5am54 flights52.9%

Scale runs 25% to 60%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 35.4% on time, against 52.9% for the 8pm–5am 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 BWI through the year

Jul–Sep 2026162 flights47.1%

Scale runs 40% to 55%.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 47.1% on time across 162 flights.

Split by quarter, JetBlue on FLL to BWI logged 162 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 47.1% annual figure is the one to use.

Arrival by arrival

How late JetBlue on FLL to BWI runs when it is late

The 81 late arrivals split 27 under half an hour, 28 between 30 and 60 minutes, and 26 an hour or more.

Share of 153 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 65 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 21 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 BWI.

The worst days

Worst days for JetBlue on FLL to BWI

The latest arrival of the period was on 12 August 2026, 10 hours 35 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Five of the five worst days fell in August 2026.

Delay causes

Why JetBlue runs late on this route

Late-arriving aircraft accounts for 42% of the 6,809 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
42%
National Airspace System
28%
Carrier
28%
Extreme weather
2%

42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,809 reported delay minutes here, that single category outweighs weather by 26 to one. The split is drawn from 6,809 reported delay minutes.

Cancellations run at 5.56%, against 1.89% nationally. That is roughly 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

17.0% 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 925 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 71.5% on time across 160 flights, 24 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 24 points of difference.

One caution: this is a thin sample. 162 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 BWI

Put together: the delay figures matter less here than the 5.56% cancellation rate. A late arrival costs you an hour and a half; a cancelled flight costs you the day. Book the 8pm–5am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 153 completed flights over 12 months sit behind that.
