Fraser Connell, Chief Flight Dispatcher at Air Canada, was recently profiled in Condé Nast Traveler’s piece This Person Is More in Control of Your Flight Than the Pilot..

"Flight dispatch is a behind-the-scenes role that is critically vital to operational success," Connell says. "Dispatchers are in the flight deck with pilots and, at the same time, we are thousands of miles ahead of the aircraft."

Journalist Allison Hope goes on to explain: "The flight dispatcher may, for instance, spot a patch of turbulence or a thunderstorm cell that developed quickly and wasn’t visible earlier, and they then radio to the pilot to take a different route to avoid a bumpier or less safe ride."
