Other routes AA370 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| CLT→ROC Charlotte to Rochester | 2026-03-08 – 2026-04-06 | 22 | — |
| ROC→CLT Rochester to Charlotte | 2026-03-08 – 2026-04-06 | 22 | — |
| ORD→DFW Chicago to Dallas–Fort Worth | 2023-11-05 – 2025-03-29 | 289 | 88.0% |
Because the same number has served different journeys, the statistics above describe only the route AA370 currently operates. Blending them would produce an average of two different flights.
When it goes wrong
The average describes a usual day. This is the day that ruins a connection.
79 min late
against a median of 1 min late
AA370 is a flight whose average understates its risk: a typical day arrives 1 min late, but the worst tenth of days are 78 minutes worse than that. If the day has something unmissable in it, the median is the wrong number to plan against.
Percentiles over 570 operations. Cancelled and diverted flights have no arrival time and are counted separately rather than as very late arrivals.
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, fuelling — 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
Share of the delay minutes US DOT attributed to each cause for AA370 on CLT → DTW. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on CLT → DTW
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| DL1405 | Delta Air Lines | 94.8% | 13 min early | 869 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 570 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 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.
