Alaska Airlines Delay and Cancellation Rates
Hawaiian Airlines was integrated into Alaska Airlines in April 2026, and Alaska now operates the former Hawaiian routes. The BTS history below covers Alaska's own flights through December 2025 and does not include Hawaiian's separate record.
Alaska Airlines (AS) flights arrived 15 or more minutes late 21.6% of the time across 724,893 flights, January 2023 to December 2025 (BTS). That is number 5 of 10 among the mainline carriers in DelayGuard's BTS data (1 is the lowest delay rate), against 21.2% for all reporting carriers. 1.58% of 491,407 scheduled flights were cancelled in 2024 to 2025, against 1.41% overall.
These figures are historical US domestic rates, not a forecast for one departure. Use the flight delay prediction before you book.
Delay window: January 2023 to December 2025. Cancellation window: 2024 to 2025. Last updated: 2026-10-18. Delayed means a flight arrived 15 or more minutes after its scheduled arrival, the BTS and DOT on-time standard. Cancelled and diverted flights are excluded from delay rates. Historical BTS figures are separate from DelayGuard's per-flight model probability and from live FAA, weather and ground-delay status.

What shapes Alaska Airlines' record
Alaska's record changes sharply by airport. Its flights from John Wayne (SNA) ran 13.1% late, against 24.5% from Sea-Tac (SEA) (airports with at least 5,000 Alaska departures).
Delays peak in June (26.3%) and are lowest in October (17.1%).
BTS reports each flight under the carrier that operated it. Flights flown by regional partners such as SkyWest, Republic, Envoy, PSA and Endeavor are reported under those operators, so this is the record of Alaska's own aircraft and crews.
