I may be flying a few weekend trips from southern cali to seattle in upcoming months. Would like direct flights. Have plenty of swa, ua, us,and aa miles. My closest airport is sna followed by lgb then lax. I've already gotten several swa, aa, ua, chase cards. Whats a good strategy to use existing miles or get a new card?

BA 15,000 roundtrip plus $25 phone

Aa or ua: 25,000 roundtrip

I rather use as/us/ua on longer flights such as those to east coast.

Southwest doesn't have direct flights.

Alaskan bonus only 25-30k. Jetblue not that good either. Havent had much experience with virgin atlantic.
