These figures cover 358 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

A 16:05 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 71.9%, and DL 419 runs level with that at 70.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
DL 419 quarter by quarter
DL 419 did not run the same all year. Its best quarter was Jul–Sep 2025 at 76.7% on time and its weakest Jul–Sep 2026 at 66.1%, a swing of 11 points on roughly 72 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, DL 419 did best on Wednesday at 86.5% on time and worst on Friday at 56.9%. Each day rests on about 51 flights, so a gap of 30 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late DL 419 runs when it is late
DL 419 often beats the schedule: 98 of 352 completed flights, 28%, arrived 15 minutes or more early. The 103 late arrivals split 48 under half an hour, 33 between 30 and 60 minutes, and 22 an hour or more.

Share of 352 completed flights by arrival against schedule.
10 of 59 late departures made up the time and arrived on time, 17% of them. In the other direction, 54 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at HNL.
The worst days
Worst days for DL 419
The latest arrival of the period was on 7 April 2026, 4 hours 43 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 April 2026 | 4 hours 43 minutes | Carrier |
| 25 February 2026 | 4 hours 39 minutes | Carrier |
| 17 November 2025 | 4 hours 32 minutes | Carrier |
| 24 January 2026 | 4 hours 29 minutes | Carrier |

Delay causes
Why DL 419 runs late
Carrier accounts for 48% of the 6,079 delay minutes carriers reported here, and the remaining four split what is left.
- 48%Carrier
- 27%National Airspace System
- 24%Late-arriving aircraft
The largest share of delay minutes, 48%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,935 of the 6,079 delay minutes reported here. The split is drawn from 6,079 delay minutes reported on DL 419.
Cancellations are rare at 0.28%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
6.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
At 2,677 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 358 flights under DL 419 in the data flew SEA to HNL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 358 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking DL 419
