Orbitz invites gay and lesbian people to “see the world on your terms” in a new print and online ad campaign for the travel company.

The work touts the Chicago-based Web site’s new “microsite,” which provides information about destinations, events and deals that are geared toward the gay and lesbian community. Orbitz estimates that this market spent $1.2 billion on travel last year.

The ads, from Chicago shop TwoHundredTwelve, feature giraffes drawn in a rainbow of colors that symbolize gay- and lesbian-friendly businesses. They bear the tagline, “Visit Planet Earth.”

“The gay community looks to the Internet when making travel plans,” said Mike Sands, Orbitz’s chief marketing officer, noting that 41 percent of gay and lesbian people have booked travel online, compared with 28 percent of other travelers, according to a study conducted by the site.

The microsite, www.or, is jointly maintained by Orbitz and PlanetOut Partners’ site. It is accessible via both sites.
