Citing a "person close to the situation," Bloomberg is reporting the travel site has postponed the roadshow for its IPO, which was to begin last week.
A representative from Kayak declined comment, citing SEC-imposed restrictions related to a proposed public offering.
Kayak, which filed to go public in November 2010, has held off for one reason or another since then. The latest delay comes after Facebook's long-awaited, but so-far lackluster IPO on May 18. Facebook, trading on Nasdaq under the symbol "FB," rose just 23 cents on its opening day and is currently down more than 20%.
Kayak is one of just a handful of Internet-based businesses going public this year. Though Facebook didn't fare well on opening day, local reviews site Yelp saw a 64% jump in its stock price when it went public on March 2.
