Other routes AA1174 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.

|---|---|---|---|
| STT→CLT Charlotte Amalie to Charlotte | 2026-03-08 – 2026-04-06 | 30 | — |
| BOS→ORD Boston to Chicago | 2026-02-12 – 2026-03-07 | 24 | — |
Because the same number has served different journeys, the statistics above describe only the route AA1174 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 564 records of AA1174 operating JFK → MIA, 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.
