JetBlue was one of the first companies to incorporate the Twitter microblogging service into its customer communications, and more than a million flyers and fans now follow the airline's tweeting staff members. Messages include announcements about fare sales (such as limited-time auctions on eBay or special on-site sales at shopping malls), celebrations of company milestones (such as the opening of the carrier's new terminal at New York's JFK airport), schedule updates, and personalized responses to people who tweet questions or complaints.

Write a tweetable message alerting JetBlue customers to the possibility that Hurricane Isaac might disrupt flight schedules from August 13 through August 15. Tell them that decisions about delays and cancelations will be made on a cityby- city basis and will be announced on Twitter and the company's website. The URL will take 20 characters, so you have 120 characters (including spaces) for your message. Email the text of your tweet to your instructor.
