Now we have just one more reason to love  Richard Branson.

The environmentalist and founder of Virgin America airlines has installed “hydration stations” at San Francisco International Airport.

Assuming you’re lucky enough to be a passenger boarding through SFO’s “green” terminal, you can now bypass the overpriced water at the gift shops and fill up your own reusable bottles. You can even buy a Virgin America-branded bottle if you forgot to bring one from home.

Virgin’s water station isn’t the first at SFO, but it is the first with a major sponsor — and the airline’s customers are singing its praises on the company’s Facebook page.

Saving the environment and cleverly promoting your brand? That’s win-win no matter how you slice — er, drink it.
