Across the year
When delays peak on this route
This route's year swings by 42 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.
January is the weak month at 45.2% on time, against 87.0% in May. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. March was the busiest month here, with 80 flights.
Across the week, Wednesday is the strongest day at 77.6% on time and Saturday the weakest at 62.4%, a spread of 15 points.
Delay causes
Why this route gets delayed
Late-arriving aircraft accounts for 45% of the 16,000 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Late-arriving aircraft
- 33%National Airspace System
- 20%Carrier
- 1%Extreme weather
45% 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 33 to one. The split is drawn from 15,606 reported delay minutes.
33% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 5,116 minutes out of 16,000, against a national NAS share of 21%.
Cancellations run at 2.75%, against 1.89% nationally. That is roughly one flight in 40 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 actually costs
12.2% 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 1,173 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 65.9% 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 67.8% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 704 completed flights over 12 months sit behind that.

The 8am–11am departure window is the strongest at 84.0% on time. The 5pm–8pm window is the weakest at 50.3%, 34 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 January delays on BDL to FLL?
