Hello,

New to the board. My husband flies 2-3 times a month roundtrip SMF to either SEA or PDX. He's been flying Southwest and is A-List status with them but he is looking to switch so he can accumulate miles on an airline offering first class and international routes for future travel.

For these short trips, which would you say is the best airline to focus all the travel with - Delta, American, Alaskan or United? Which is going to give him the best earning potential and higher status in the fastest time? his roundtrip fares usually average around $500 per trip if that helps. TIA for your advice!
