Thanks guys for your response [MENTION=22712]chgoeditor[/MENTION] I sort of meant that which program should I channel my flight segments towards. When I said I was looking at Southwest it meant that I was only researching its benefits, sorry for the confusion.

No I do not anticipate going anywhere else most likely from LA to SFO and SFO to LA routes.

So essentially I just wanted to ask whether I could channel my segments anywhere useful so I can get the most benefits at the airport/flying. For free tickets, the reason why I did not place an emphasis on them because it would take around 40 segments to hit 12,500 miles when sometimes airlines offer them for only $39 one way or $59.
