What stands out
How B61131 compares to other flight numbers, not just to itself.
Which day you fly matters unusually much here, a wider weekday spread than 95% of 1,710 comparable flight numbers.
85.7% on time on a typical Tuesday, against 66.2% on a Sunday.

Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| B61131 | 76.5% | 0.71% | -6 min | 10.3% | 982 |
| JetBlue on CHS → FLL | 76.2% | 0.87% | -6 min | 10.4% | 1,033 |
| All CHS → FLL flights | 76.2% | 1.75% | -6 min | 10.8% | 1,832 |
B61131 has cancelled 0.71% of its scheduled departures (7 of 982), against 1.75% for all CHS → FLL flights — this specific departure cancels 1.0 percentage points less often than the route as a whole. Different flight numbers on the same route can carry different aircraft, crews and schedules, so this is a fact about B61131 specifically, not about the route it flies.

Why B61131 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
Share of the delay minutes US DOT attributed to each cause for B61131 on CHS → FLL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies B61131 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B61131 pushed back an average of 60 minutes late; when it came in on time or early, an average of 0 minutes early.
Each departure is matched to the flight the same aircraft flew into CHS just before it, using the tail number in the DOT file, 961 of 975 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| B61131 | 20% | 75% | 8% |
| Network, same turn | 18% | 85% | 10% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 45 to 59 minutes. How often B61131’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often B61131 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves CHS late, does that still matter by the time it reaches FLL?
B61131 pushes back an average of 14.2 minutes late and reaches the gate at FLL an average of 11.3 minutes late. The 2.9 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 14.9 minutes on the taxiways at CHS, 1.2 minutes shorter than a typical CHS departure in the same hour.
On arrival at FLL, B61131 spends 6.7 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at FLL spends on the ground before reaching the gate.
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached FLL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 2,285 departures from CHS scheduled in the clock hour B61131 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at FLL (278,720 flights), not just B61131’s own. More on taxi time.

The hour it leaves CHS
Part of any flight’s record belongs to the clock rather than to the flight. B61131 has one departure time, so this is what that time is worth.
On-time arrival rate. 2,285 departures from CHS are scheduled in the 9 AM–10 AM hour over the period, against 77,398 across the whole day.
B61131 is scheduled out of CHS at 9:30 AM, in the 9 AM–10 AM bank. Departures from CHS in that hour arrive on time 87.9% of the time against 80.6% across the airport’s whole day — the slot alone is worth 7.3 points better before anything about this particular flight is considered.
The two airport figures cover every departure from CHS to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

By day of week
Does B61131 run worse on particular days?
Tuesday is historically the most reliable day and Sunday the least, a gap of 19.5 percentage points.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
61 min late
against a median of 6 min early
B61131 has an average that understates its risk: a typical arrival is 6 min early, but the worst tenth are 67 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 982 records of B61131 operating CHS → FLL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
