Why AA703 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
Share of the delay minutes US DOT attributed to each cause for AA703 on CLT → BUF. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies AA703 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, AA703 pushed back an average of 62 minutes late; when it came in on time or early, an average of 12 minutes late.
Each departure is matched to the flight the same aircraft flew into CLT just before it, using the tail number in the DOT file, 800 of 868 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 |
|---|---|---|---|
| AA703 | 31% | 74% | 21% |
| Network, same turn | 17% | 68% | 9% |
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 60 to 89 minutes. How often AA703’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA703 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 BUF?
AA703 pushes back an average of 32.5 minutes late and reaches the gate at BUF an average of 27.4 minutes late. The 5.0 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 17.7 minutes on the taxiways at CLT, 2.3 minutes shorter than a typical CLT departure in the same hour.
On arrival at BUF, AA703 spends 6.0 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 BUF 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 BUF. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 49,147 departures from CLT scheduled in the clock hour AA703 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BUF (65,593 flights), not just AA703’s own. More on taxi time.

The hour it leaves CLT
Part of any flight’s record belongs to the clock rather than to the flight. AA703 has one departure time, so this is what that time is worth.
On-time arrival rate. 49,147 departures from CLT are scheduled in the 10 PM–11 PM hour over the period, against 618,243 across the whole day.
AA703 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 66.6% of the time against 74.8% across the airport’s whole day — the slot alone is worth 8.2 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from CLT 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 AA703 run worse on particular days?
Tuesday is historically the most reliable day and Thursday the least, a gap of 14.6 percentage points.

Other routes AA703 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 |
|---|---|---|---|
| DFW→ORD Dallas–Fort Worth to Chicago | February 12, 2026 – March 7, 2026 | 24 | — |
| CLT→EGE Charlotte to Eagle | December 18, 2025 – January 5, 2026 | 19 | — |
| GRR→ORD Grand Rapids to Chicago | November 30, 2025 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route AA703 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.
77 min late
against a median of 4 min late
AA703 has an average that understates its risk: a typical arrival is 4 min late, but the worst tenth are 74 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Other flights on this route
Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|
| AA1203 | American Airlines | 86.4% | 6 min early | 678 |
| AA703 this flight | American Airlines | 62.5% | 4 min late | 890 |
Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA703 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 890 records of AA703 operating CLT → BUF, 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.
