Why UA1605 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
Share of the delay minutes US DOT attributed to each cause for UA1605 on LAX → BWI. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies UA1605 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, UA1605 pushed back an average of 14 minutes late; when it came in on time or early, an average of 2 minutes early.
Each departure is matched to the flight the same aircraft flew into LAX just before it, using the tail number in the DOT file, 737 of 820 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 |
|---|---|---|---|
| UA1605 | 18% | 37% | 5% |
| Network, same turn | 23% | 40% | 9% |
The schedule leaves a long gap on the ground, which gives a late aircraft room to catch up before this flight pushes back.
The network row is every flight with a scheduled turn of 90 minutes to 3 hours. How often UA1605’s aircraft landed 15 or more minutes late is lower than the network’s and, once the aircraft was late, how often UA1605 left 15 or more minutes late is about the same as the network’s.

From pushback to gate
When it leaves LAX late, does that still matter by the time it reaches BWI?
UA1605 pushes back an average of 2.7 minutes late and reaches the gate at BWI an average of 7.7 minutes early. The 10.4 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 20.1 minutes on the taxiways at LAX is about what any departure from the airport in that hour spends.
On arrival at BWI, UA1605 spends 5.9 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 BWI 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 BWI. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 22,331 departures from LAX scheduled in the clock hour UA1605 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at BWI (299,179 flights), not just UA1605’s own. More on taxi time.

The hour it leaves LAX
Part of any flight’s record belongs to the clock rather than to the flight. UA1605 has one departure time, so this is what that time is worth.
On-time arrival rate. 22,331 departures from LAX are scheduled in the 11 PM–12 AM hour over the period, against 595,153 across the whole day.
UA1605 is scheduled out of LAX at 11:59 PM, in the 11 PM–12 AM bank. Departures from LAX in that hour arrive on time 80.8% of the time against 81.4% across the airport’s whole day, so the hour UA1605 leaves in is an ordinary one for LAX and explains nothing about its record either way.
The two airport figures cover every departure from LAX 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 UA1605 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 833 records of UA1605 operating LAX → BWI, 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.
