Why DL483 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
Share of the delay minutes US DOT attributed to each cause for DL483 on ATL → BUR. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL483 comes in late, and what that does to the departure.
The aircraft flying DL483 came in 15 or more minutes late on 15% 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, 653 of 756 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 |
|---|---|
| DL483 | 15% |
| Network, same turn | 17% |
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 DL483’s aircraft landed 15 or more minutes late is about the same as 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 BUR?
On arrival at BUR, DL483 spends 6.8 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 2.4 minutes longer than a typical BUR arrival (4.4 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 BUR. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 60,290 departures from ATL scheduled in the clock hour DL483 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BUR (93,650 flights), not just DL483’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. DL483 has one departure time, so this is what that time is worth.
On-time arrival rate. 60,290 departures from ATL are scheduled in the 10 AM–11 AM hour over the period, against 1,012,247 across the whole day.
DL483 is scheduled out of ATL at 10:25 AM, in the 10 AM–11 AM 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.

Other routes DL483 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 |
|---|---|---|---|
| BUR→ATL Burbank to Atlanta | June 8, 2025 – July 31, 2026 | 340 | 71.8% |
| SLC→ATL Salt Lake City to Atlanta | April 9, 2024 – May 6, 2024 | 28 | — |
| DTW→LAX Detroit to Los Angeles | January 8, 2024 – March 9, 2024 | 62 | — |
| DFW→ATL Dallas–Fort Worth to Atlanta | November 23, 2023 | 1 | — |
Because the same number has served different journeys, the statistics above describe only the route DL483 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.
63 min late
against a median of 1 min late
DL483 has an average that understates its risk: a typical arrival is 1 min late, but the worst tenth are 62 minutes worse than that. If the trip has something unmissable at the end of it, the median is the wrong number to plan against.

Data and methodology
Calculated by FlyerIntel from 771 records of DL483 operating ATL → BUR, 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.
