Insider Cheers & Jeers

“CHEERS to Priceline.com for beaming up Star Trek veterans William Shatner and Leonard Nimoy in a new, out-of-this-world commercial.  We just hope the ad’s premise that Nimoy is replacing Shatner as the company’s spokesman isn’t true.  Keeping Captain Kirk and Mr. Spock together is only logical.”

• 40+ newspaper articles to date

• Over 50 TV pickups

2004 Outlook

•Momentum in new retail choice airline ticket product

•Strong results in hotel and rental car

•Increasing airline ticket demand and new retail choice product in packages brings accelerated growth

•New retail choices for hotel (via Travelweb acquisition) and rental car in development

•Extension of Shatner/Nimoy ad campaign for Air and Hotel
