Every carrier on BWI to FLL, 3,168 flights

These figures cover 160 flights between September 2025 and August 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Carrier by carrier

JetBlue against every carrier on BWI to FLL

JetBlue flew 160 of the 3,168 flights on BWI to FLL, about 5% of it. Its 71.5% on time is 3 points worse than the route as a whole, which runs 74.5%. Ranked by on-time rate it is number three of four carriers on the route, where the range runs from Spirit at 78.0% to Frontier at 51.3%. One of those carriers flew fewer than 365 flights here, so treat their positions as rough.

The two carriers here are closely matched: 2 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.

When JetBlue runs best on this route

Book the early departure. Flights leaving between 5am–8am arrive on time 83.0% of the time, against 53.7% for the afternoon window. That is 29 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.

Delay causes

Why JetBlue runs late on this route

Late-arriving aircraft accounts for 49% of the 3,496 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
49%
Carrier
23%
National Airspace System
17%
Extreme weather
11%

49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,496 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 3,496 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 83.0% on time here.

Cancellations run at 5.00%, 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

7.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.

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 47.1% on time across 162 flights, 24 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 24 points of difference.

One caution: this is a thin sample. 160 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 BWI to FLL

Put together: the delay figures matter less here than the 5.00% 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. 151 completed flights over 12 months sit behind that.
