Does a late aircraft delay this flight?

How often the plane that flies UA1327 comes in late, and what that does to the departure.

Inbound aircraft late
11%
70 of 622 departures came in 15+ minutes late
Scheduled time on the ground
56 minutes
Median at ATL between the inbound and this departure

The aircraft flying UA1327 came in 15 or more minutes late on 11% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.

Each departure is matched to the flight the same aircraft flew into ATL just before it, using the tail number in the DOT file, 622 of 655 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

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 45 to 59 minutes. How often UA1327’s aircraft landed 15 or more minutes late is lower than the network’s. There are not enough departures in both groups to compare how it left.

From pushback to gate

When it leaves ATL late, does that still matter by the time it reaches DEN?

Leaves the gate
8.8 minutes late
Average over 655 pushbacks
Taxi out at ATL
18.1 min
15.9 min for the airport in this hour
Taxi in at DEN
8.7 min
9.8 min for a typical DEN arrival
Reaches the gate at DEN
0.4 minutes early
Average over 655 arrivals

UA1327 pushes back an average of 8.8 minutes late and reaches the gate at DEN an average of 0.4 minutes early. The 9.3 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 18.1 minutes on the taxiways at ATL, 2.2 minutes longer than a typical ATL departure in the same hour.

On arrival at DEN, UA1327 spends 8.7 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 1.1 minutes shorter than a typical DEN arrival (9.8 min).

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 DEN. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 68,577 departures from ATL scheduled in the clock hour UA1327 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at DEN (963,027 flights), not just UA1327’s own. More on taxi time.

The hour it leaves ATL

Part of any flight’s record belongs to the clock rather than to the flight. UA1327 has one departure time, so this is what that time is worth.

UA132788.4%
All ATL departures, 11 AM–12 PM84.0%
All ATL departures, whole day78.7%

On-time arrival rate. 68,577 departures from ATL are scheduled in the 11 AM–12 PM hour over the period, against 1,012,247 across the whole day.

UA1327 is scheduled out of ATL at 11:10 AM, in the 11 AM–12 PM bank. Departures from ATL in that hour arrive on time 84.0% of the time against 78.7% across the airport’s whole day — the slot alone is worth 5.2 points better before anything about this particular flight is considered.

The two airport figures cover every departure from ATL 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.

Because the same number has served different journeys, the statistics above describe only the route UA1327 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. UA1327 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 659 records of UA1327 operating ATL → DEN, 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.
