DL2122
Minneapolis (MSP) to Los Angeles (LAX) · scheduled 6:59 PM – 8:50 PM
How DL2122 performs
737 operations, June 2024 – July 2026.
DL2122 arrived on time 76.4% of the time, against 84.5% for all MSP → LAX flights, so this departure is 8.1 percentage points worse than the route as a whole. Against Delta Air Lines’ own flights on this route it is 8.1 points worse.
DL2122’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 6:30 PM earlier on, and around 7:00 PM more recently — a 30-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

Why DL2122 runs late
Where US DOT attributed the delay minutes on this flight.
the inbound aircraft was late, so this flight started late
crew, maintenance, boarding and fueling, all within the carrier’s control
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 DL2122 on MSP → LAX. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies DL2122 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, DL2122 pushed back an average of 57 minutes late; when it came in on time or early, an average of 5 minutes late.
Each departure is matched to the flight the same aircraft flew into MSP just before it, using the tail number in the DOT file, 689 of 732 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 |
|---|---|---|---|
| DL2122 | 17% | 82% | 14% |
| Network, same turn | 17% | 68% | 9% |
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 DL2122’s aircraft landed 15 or more minutes late is about the same as the network’s and, once the aircraft was late, how often DL2122 left 15 or more minutes late is higher than the network’s.

From pushback to gate
When it leaves MSP late, does that still matter by the time it reaches LAX?
DL2122 pushes back an average of 14.8 minutes late and reaches the gate at LAX an average of 4.4 minutes late. 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 18.0 minutes on the taxiways at MSP is about what any departure from the airport in that hour spends.
On arrival at LAX, DL2122 spends 11.9 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 1.2 minutes longer than a typical LAX arrival (10.7 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 LAX. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 33,761 departures from MSP scheduled in the clock hour DL2122 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LAX (595,170 flights), not just DL2122’s own. More on taxi time.

The hour it leaves MSP
Part of any flight’s record belongs to the clock rather than to the flight. DL2122 has one departure time, so this is what that time is worth.
On-time arrival rate. 33,761 departures from MSP are scheduled in the 6 PM–7 PM hour over the period, against 369,781 across the whole day.
DL2122 is scheduled out of MSP at 6:59 PM, in the 6 PM–7 PM bank. Departures from MSP in that hour arrive on time 75.1% of the time against 81.1% across the airport’s whole day — the slot alone is worth 6.0 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from MSP 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 DL2122 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. DL2122 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 737 records of DL2122 operating MSP → LAX, 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.
