Departure window
The best time of day to leave
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 27 points, against half a point between the best and worst carrier.
- 5am–8am59 flights83.9%
- 8am–11am135 flights78.6%
- 11am–2pm111 flights56.9%
- 2pm–5pm51 flights62.0%
- 5pm–8pm85 flights75.9%
- 8pm–5am285 flights57.6%
Scale runs 50% to 90%.
The weak window here is the middle of the day, not the evening: 11am–2pm runs 56.9% on time against 83.9% for 5am–8am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8pm–5am window is the busiest, with 285 flights scheduled in it.

Across the year
When delays peak on this route
This route's year swings by 52 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.
July is the worst month at 37.9% on time, 52 points below September, the best at 90.0%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. March was the busiest month here, with 80 flights.
Across the week, Saturday is the strongest day at 70.7% on time and Sunday the weakest at 58.4%, a spread of 12 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 47% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 37%Carrier
- 13%National Airspace System
- 3%Extreme weather
- 0%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 16,000 reported delay minutes here, that single category outweighs weather by 18 to one. The split is drawn from 15,980 reported delay minutes.
The largest share of delay minutes, 37%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,855 of the 16,000 delay minutes reported here.
Cancellations sit at 2.20% against a national 1.89%, which is ordinary. Diversions add another 0.41%.
Connections and stage length
What a delay here actually costs
13.9% 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 1,173 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 runs 67.8% on time across 726 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 726 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 this route
Put together: treat all of this as provisional. 726 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 65.9% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 707 completed flights over 12 months sit behind that.

The 5am–8am departure window is the strongest at 83.9% on time. The 11am–2pm window is the weakest at 56.9%, 27 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are July delays on FLL to BDL?
