What stands out
How OO4084 compares to other flight numbers, not just to itself.
This flight stays close to typical even on its worst days, a smaller gap than 94% of 11,788 comparable flight numbers.
A typical arrival is 13 min early, and the worst tenth are only 20 minutes worse than that.

Why OO4084 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
weather severe enough to stop this flight specifically
airspace and airport capacity, including weather-driven flow control

Does a late aircraft delay this flight?
How often the plane that flies OO4084 comes in late, and what that does to the departure.
The aircraft flying OO4084 came in 15 or more minutes late on 4% 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 SLC just before it, using the tail number in the DOT file, 832 of 966 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 |
|---|---|
| OO4084 | 4% |
| 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 OO4084’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 SLC late, does that still matter by the time it reaches ABQ?
OO4084 pushes back an average of 0.9 minutes early and reaches the gate at ABQ an average of 8.2 minutes early. The 7.3 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 21.1 minutes on the taxiways at SLC, 1.1 minutes longer than a typical SLC departure in the same hour.
On arrival at ABQ, OO4084 spends 7.6 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 longer than a typical ABQ arrival (6.0 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 ABQ. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 26,936 departures from SLC scheduled in the clock hour OO4084 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at ABQ (76,020 flights), not just OO4084’s own. More on taxi time.

The hour it leaves SLC
Part of any flight’s record belongs to the clock rather than to the flight. OO4084 has one departure time, so this is what that time is worth.
On-time arrival rate. 26,936 departures from SLC are scheduled in the 9 AM–10 AM hour over the period, against 355,300 across the whole day.
OO4084 is scheduled out of SLC at 9:25 AM, in the 9 AM–10 AM bank. Departures from SLC in that hour arrive on time 88.0% of the time against 84.0% across the airport’s whole day — the slot alone is worth 4.0 points better before anything about this particular flight is considered.
The two airport figures cover every departure from SLC 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 OO4084 run worse on particular days?
Friday is historically the most reliable day and Saturday the least, a gap of 8.2 percentage points.

Because the same number has served different journeys, the statistics above describe only the route OO4084 currently operates. Blending them would produce an average of two different flights.

Other flights on this route
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. OO4084 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 966 records of OO4084 operating SLC → ABQ, 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.
