Best FF program for LAX/BUR/ONT->SFO/OAK/SJC
Of your choices from LAX all of the terminals are in major reconstruction and the SW terminal is about the worst for congestion. From BUR or ONT the airports are easier to handle but that limits you mostly to SW. Alaska did fly into OAK from LA but not sure about now. Because of the $$$ component needed for elite on UA and DL that makes them unattractive for purely these shuttling flights. VX has a great product though.
