Since award travel from British Airways Avios is distance based, it takes very few of them to fly on American Airlines between San Francisco and Los Angeles. For a $95 annual fee the current British Airways credit card offer gives you

• 50,000 bonus Avios after your first purchase
• 25,000 bonus Avios after you make $10,000 in purchases within the first year of account opening
• Plus an additional 25,000 bonus Avios after you make an additional $10,000 in purchases also within the first year of account opening
• 2.5 Avios for every $1 spent on British Airways purchases and 1.25 Avios for every $1 spent on all other purchases

The 25K points alone should get you a few round trips between SFO and LAX.
