NEW YORK (YouTube.com/AdAge) -- The stars of "Entourage" and Virgin chief Richard Branson dueled each other with champagne spray on Friday as they celebrated the co-marketing of a new flight route and a new season of shows. The hit HBO series and airline company co-hosted a splashy PR event in a private hanger at JFK airport. A Virgin plane was repainted as "Entourage Air" for a month of the new flight service from JFK to Las Vegas. The event also marked the first time that the season opener of a major TV series was premiered in-flight.
