According the Apple support, you need an optical drive to install Windows with Bootcamp. But I did find this post on reviews.cnet.com that shows to install Windows 7 on a MacBook Air from a USB drive, so I’m going to try that. As soon as I decide whether to spend yet more money and purchase Windows 7.
