Against the rest of the route
| Flight or route | On time | Cancelled | Median delay | Severe | Flights |
|---|---|---|---|---|---|
| AA370 | 64.8% | 3.02% | 2 min | 14.9% | 630 |
| American Airlines on CLT → DTW | 75.6% | 1.35% | -4 min | 8.9% | 6,373 |
| All CLT → DTW flights | 80.5% | 1.11% | -7 min | 7.4% | 11,459 |
AA370 has cancelled 3.02% of its scheduled departures (19 of 630), against 1.11% for all CLT → DTW flights — this specific departure cancels 1.9 percentage points more 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 AA370 specifically, not about the route it flies.
14.9% of AA370’s arrivals were an hour or more late, against 7.4% across CLT → DTW, so the long delays are more common on this number than on the route.

Why AA370 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
weather severe enough to stop this flight specifically
airspace and airport capacity, including weather-driven flow control
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies AA370 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA370 pushed back an average of 66 minutes late; when it came in on time or early, an average of 10 minutes late.
Matched by tail number to the aircraft’s previous flight into CLT: 538 of 612 departures. Unknown, cancelled or diverted inbounds and gaps over 12 hours are left out.
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 |
|---|---|---|---|
| AA370 | 38% | 72% | 20% |
| Network, same turn | 17% | 69% | 9% |
70 scheduled minutes is enough to clean and board when the aircraft is on time, with little to spare when it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often AA370’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA370 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves CLT late, does that still matter by the time it reaches DTW?
AA370 pushes back an average of 34.5 minutes late and reaches the gate at DTW an average of 27.0 minutes late. The 7.4 minutes between those two figures are slack the published schedule already carries, so a late pushback is partly, not fully, made up before the gate. It spends 17.8 minutes on the taxiways at CLT, 2.3 minutes shorter than a typical CLT departure in the same hour.
On arrival at DTW, AA370 spends 9.7 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 DTW spends on the ground before reaching the gate.
Taxi-out is gate to wheels up and sits inside the scheduled block; the hourly comparison is 49,869 CLT departures. Taxi-in is landing to gate, set against 398,786 arrivals at DTW. More on taxi time.

The hour it leaves CLT
AA370 has one departure time, 10:45 PM, so this is what that hour at CLT is worth.
On-time arrival rate. 49,869 departures from CLT are scheduled in the 10 PM–11 PM hour over the period, against 633,368 across the whole day.
AA370 is scheduled out of CLT at 10:45 PM, in the 10 PM–11 PM bank. Departures from CLT in that hour arrive on time 66.4% of the time against 74.6% across the airport’s whole day — the slot alone is worth 8.2 points worse before anything about this particular flight is considered.
Both airport figures cover every destination from CLT, so they describe the slot, not this journey; the route comparison is above. Why the hour matters.

When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
81 min late
against a median of 2 min late
AA370 has an average that understates its risk: a typical arrival is 2 min late, but the worst tenth are 79 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 630 records of AA370 operating CLT → DTW, 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 reported separately, not in the on-time rate.
