AS Lounges are available at SEA, LAX, JFK, and a few other airports. Oneworld partner lounges accessible for eligible passengers at all stations.
Operational Issues
SEA experiences low-visibility fog in autumn and winter. Pacific Northwest weather generally causes fewer delays than East Coast or Midwest hubs. Alaska state routes (ANC, FAI, JNU) can be affected by winter weather and have limited rebooking options due to low frequency. AS consistently ranks among the top US carriers for on-time performance. Hawaii routes are weather-reliable. AS fleet is primarily Boeing 737 variants, simplifying operations but limiting range for potential future long-haul expansion.
