AA1665
Las Vegas (LAS) to Charlotte (CLT) · scheduled 8:00 AM – 3:28 PM
How AA1665 performs
917 operations, July 2023 – July 2026.
AA1665 arrived on time 85.3% of the time, against 82.0% for all LAS → CLT flights, so this departure is 3.3 percentage points better than the route as a whole. Against American Airlines’ own flights on this route it is 2.8 points better.
AA1665’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 6:00 AM earlier on, and around 8:00 AM more recently — a 120-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Why AA1665 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
weather severe enough to stop this flight specifically
screening or terminal security incidents

Does a late aircraft delay this flight?
How often the plane that flies AA1665 comes in late, and what that does to the departure.
AA1665 is usually the aircraft’s first flight of the day: the schedule gives it a median of 9.7 hours on the ground at LAS, so its “inbound” is mostly the aircraft’s arrival the evening before.
When the aircraft came in 15 or more minutes late, AA1665 pushed back an average of 15 minutes late; when it came in on time or early, an average of 6 minutes late.
Each departure is matched to the flight the same aircraft flew into LAS just before it, using the tail number in the DOT file, 584 of 912 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 |
|---|---|---|---|
| AA1665 | 39% | 19% | 9% |
| Network, same turn | 29% | 12% | 9% |
A night on the ground absorbs most of a late arrival, so a late inbound matters far less on a turn this long than on a same-day one.
The network row is every flight with a scheduled turn of 6 hours or more, usually overnight. How often AA1665’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often AA1665 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves LAS late, does that still matter by the time it reaches CLT?
AA1665 pushes back an average of 14.6 minutes late and reaches the gate at CLT an average of 3.6 minutes late. The 11.0 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. Its 17.3 minutes on the taxiways at LAS is about what any departure from the airport in that hour spends.
On arrival at CLT, AA1665 spends 12.7 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 CLT 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 CLT. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 37,259 departures from LAS scheduled in the clock hour AA1665 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at CLT (618,237 flights), not just AA1665’s own. More on taxi time.

The hour it leaves LAS
Part of any flight’s record belongs to the clock rather than to the flight. AA1665 has one departure time, so this is what that time is worth.
On-time arrival rate. 37,259 departures from LAS are scheduled in the 8 AM–9 AM hour over the period, against 569,617 across the whole day.
AA1665 is scheduled out of LAS at 8:00 AM, in the 8 AM–9 AM bank. Departures from LAS in that hour arrive on time 86.4% of the time against 78.0% across the airport’s whole day — the slot alone is worth 8.4 points better before anything about this particular flight is considered.
The two airport figures cover every departure from LAS 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 AA1665 run worse on particular days?
Thursday is historically the most reliable day and Monday the least, a gap of 11.9 percentage points.

Because the same number has served different journeys, the statistics above describe only the route AA1665 currently operates. Blending them would produce an average of two different flights.

Same airports, same journey, different odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. AA1665 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 917 records of AA1665 operating LAS → CLT, 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.
