Gays are more likely than heterosexuals to book travel online, according to a new Harris Interactive study, reports eMarketer. The Harris survey was conducted in mid-March and found that 35 percent of heterosexual respondents said they don't book travel online, compared with 18 percent of gay, lesbian and bisexual (GLB) respondents.

All the major online travel sites are more popular among GLB Web surfers than among heterosexuals.

Travelocity was the most popular site for booking hotel rooms regardless of sexual orientation, though it was considerably more popular among GLB adults: over 50 percent said they visit Travelocity when making reservations.
