These figures cover 336 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.

- 0%Late-arriving aircraft
The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,086 of the 1,403 delay minutes reported here. The split is drawn from 1,403 delay minutes reported on B6 1480.

Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 899 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.
Every one of the 336 flights under B6 1480 in the data flew FLL to DCA. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 336 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 B6 1480
For a booking, the cancellation rate is the figure to plan around on B6 1480: 2.68% of its 336 scheduled flights did not operate. A late arrival costs roughly 50 minutes, but a cancellation costs the day, so leave a later option open.
