Why UA219 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
weather severe enough to stop this flight specifically

Does a late aircraft delay this flight?
How often the plane that flies UA219 comes in late, and what that does to the departure.
The aircraft flying UA219 came in 15 or more minutes late on 8% 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 ORD just before it, using the tail number in the DOT file, 464 of 1,123 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 |
|---|---|
| UA219 | 8% |
| Network, same turn | 33% |
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 3 to 6 hours. How often UA219’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 ORD late, does that still matter by the time it reaches HNL?
UA219 pushes back an average of 10.7 minutes late and reaches the gate at HNL an average of 5.2 minutes early. The 16.0 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 26.1 minutes on the taxiways at ORD, 1.5 minutes shorter than a typical ORD departure in the same hour.
On arrival at HNL, UA219 spends 6.7 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 1.6 minutes shorter than a typical HNL arrival (8.3 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 HNL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 68,561 departures from ORD scheduled in the clock hour UA219 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at HNL (186,355 flights), not just UA219’s own. More on taxi time.

The hour it leaves ORD
Part of any flight’s record belongs to the clock rather than to the flight. UA219 has one departure time, so this is what that time is worth.
On-time arrival rate. 68,561 departures from ORD are scheduled in the 9 AM–10 AM hour over the period, against 952,802 across the whole day.
UA219 is scheduled out of ORD at 9:30 AM, in the 9 AM–10 AM bank. Departures from ORD in that hour arrive on time 80.2% of the time against 74.5% across the airport’s whole day — the slot alone is worth 5.7 points better before anything about this particular flight is considered.
The two airport figures cover every departure from ORD 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 UA219 run worse on particular days?
Tuesday is historically the most reliable day and Friday the least, a gap of 11.3 percentage points.

Other routes UA219 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 |
|---|---|---|---|
| AUS→ORD Austin to Chicago | March 7–8, 2025 | 2 | — |
| ORF→ORD Norfolk to Chicago | January 7, 2025 – February 12, 2025 | 37 | — |
| MCO→ORD Orlando to Chicago | November 30, 2024 – December 1, 2024 | 2 | — |
Because the same number has served different journeys, the statistics above describe only the route UA219 currently operates. Blending them would produce an average of two different flights.

Data and methodology
Calculated by FlyerIntel from 1,127 records of UA219 operating ORD → HNL, 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.
