Alaska Airlines recommends passengers with checked bags arrive 90 minutes before departure and 60 minutes prior with carry on. Passengers who are checking bags must check them in at least 40 minutes prior to departure. In addition, the boarding gate closes 10 minutes prior to departure. You should get through Security screening to the waiting area at least 30 minutes prior to departure so you do not miss your flight.
Do do not delay, get here early. It is a small airport, but flights connect to large hubs. It takes time to screen and board passengers. It is important to get everyone on board so the aircraft can depart on time. Too often we see passengers who cut it too close miss their flights. Sometimes they wait in the lobby too long before going through Security and miss their flights! We do not like to see this happen!
Give yourself plenty of time to get to the Airport and through Security, unexpected delays can happen anywhere. Do not risk missing your flight!
