Other routes DL351 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 |
|---|---|---|---|
| LIH→LAX Lihue, Kauai to Los Angeles | 2023-07-01 – 2024-09-08 | 435 | 95.6% |
| LAX→LIH Los Angeles to Lihue, Kauai | 2023-07-01 – 2024-03-09 | 145 | 88.3% |
Because the same number has served different journeys, the statistics above describe only the route DL351 currently operates. Blending them would produce an average of two different flights.
Data and methodology
Calculated by FlyerIntel from 660 records of DL351 operating SEA → 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.
