Most of our existing miles are with United, and we've had the United Visa from Chase for a long while.

However, a recent overseas trip revealed a 3% fee for international transactions, which I don't like. My job now will have more international travel--good for racking up the miles, but I'd like to avoid that fee. Time for a new card?

A financial website recommended the Capital One Venture Rewards Visa, reporting that Money magazine called it "'Best Rewards Card if you aim to rack up airline miles." Hmm.
