Liz Owen needed help, and she needed it fast.
She had rescheduled a flight from Washington to Los Angeles on Virgin America to avoid superstorm Sandy, which was about to slam into the East Coast. But she’d forgotten to order a wheelchair.
Owen, who works for a nonprofit organization in Washington, had recently broken her foot, which was in a cast. “I had been on the phone on hold with Virgin America for well over an hour,” she remembers. Halfway to the airport, she decided to send Virgin America a tweet — a message on the microblogging service Twitter.
