A lot of people, including investors in Gogobot and Delta Air Lines management, are betting on social travel -- or at least playing around with it.
Gogobot, a social travel-planning site, announced today that it completed a new funding round of $15 million, bringing its stockpile to $19 million to date.
The latest round was led by Redpoint Ventures, and Satish Dharmaraj, general partner of Redpoint Ventures, joins the Gogobot board.
Also participating in the $15 million round were Michael Arrington's CrunchFund and Battery Ventures.
Battery Ventures was a previous investor while CrunchFund and Redpoint Ventures are new to the party.
In addition to Battery Ventures, other prior investors were Eric Schmidt's Innovation Endeavors, MySpace founder Chris DeWolfe, Square general manager Keith Rabois, and angel investor Oren Ze'ev.
Gogobot says it will use the new dinero "to expand its global footprint through marketing, partnerships and outreach."
"We've lots of momentum behind the company and we'll be using the funding to continue to grow and bring the power of social travel to the masses," says Travis Katz, Gogobot co-founder and CEO.
Katz declines to specify monthly unique visitor numbers, but says Gogobot's "user base did increase ten times in the last six months."
Meanwhile, Delta Air Lines, which previously developed Facebook apps such as Delta Ticket Counter and DeltaAssist, introduced a new one called Delta Away We Go.
The app is sort of a group travel planning and sharing feature for Facebook.
It's designed to be very social.
Through Delta Away We Go, you can share your trip information with Facebook friends, search for destinations and activities, keep tabs on friends who are coming along, and track how soon you'll depart with a Countdown Calendar.
