The stock of online travel site Kayak.com just commenced trading on the NASDAQ exchange under the symbol KYAK. At its public debut, the share price promptly soared more than 14 percent to $30.10, giving the company a market cap of well over $1 billion. At the time of publication, shares were up 22.3 percent (and rising). The stock closed for the day at just North of $33 per share.

Yesterday, Kayak sold 3.5 million shares at $26 a pop, bringing capital raised through the (delayed) IPO to $91 million.

The company had priced the offering above its proposed $22 to $25 range. It’s the first United States-based consumer Internet company to go public since Facebook’s initial public offering last May.

Kayak initially filed for its IPO in November 2010 but had recently put the plans on hold following Facebook’s messy IPO and subsequent drop in share price.

For the four quarters ended March 2012, the online travel search and technology company generated $245 million in revenue, and $17.5 million in after-tax income.

For the three months ended March 31, 2012, Kayak generated $73.3 million of revenues.

The company was started back in 2004 by co-founders of popular travel sites Expedia, Travelocity and Orbitz.

According to Crunchbase data, Kayak raised $223 million in funding from investors like AOL, General Catalyst Partners, Sequoia Capital and Accel Partners.
