It’s tough to be grounded when you work 35,000 feet in the air.  And CW viewers will enjoy an intimate peek into the lives of charismatic flight attendants in Fly Girls, a new reality docu-series debuting midseason.  Five Virgin America stewardesses jet from one exotic locale to the next, while pursuing good times, great parties, adventure and love.  Founded in 2007, the airline has “reinvented the experience of flying,” its vp notes, “with mood-lit cabins, concierge-like service, and a sophisticated vibe,” winning Best Domestic Airline honors two straight years.  Think about this challenging occupation—long hours in the air, layovers in intriguing cities, demanding or sometimes fascinating passengers, split-second decision-making.  Fly Girls will show us a rarely-seen perspective of the industry.  Eight half-hour episodes have been ordered, and there’s a good chance they’ll be paired with another 30-minute midseason reality series, Blonde Charity Mafia, which chronicles three social mavens in the Washington, D.C. inner circle.
