Terminal A has American, Delta, United, and Jet Blue. Terminal B has Aeroméxico, Hawaiian, Alaska, Horizon, Seaport, Southwest and Volaris.
Go to SMF website. Too many to list here.
Very simple,only two terminals and carriers are listed on one or the other terminal. Check flight tickets for carrier listed and follow the signage as you go towards the entrance of the airport.
