I live in southern California in an area where I have 4 airports within an hour (the biggest one being LAX being about 45 minutes away- but I live very close to a medium size airport) all the big airlines fly to the 4 airports. Is it worth getting an airline card? I fly about 5-7 times a year and would be willing to drive for a good flight. Would ideally like to use points as much as I can.
