Not necessarily - be careful. Airlines can choose to offer a fee-free hold instead. While it was an anamoly, AA used to do the hold instead and I've definitely seen reports of folks being denied a refund within 24 hours. Though I'm pretty certain they switched to the refund route now, or are in the process.
Not sure if any other of the majors use the hold option, but definitely something you want to know before plunking your CC down and finding out when it's too late.
