A combination of snow, ice, fog, and new rules brought the national air transportation system to its knees Monday, leaving thousands of passengers stranded at Logan International and airports around the country — some for as long as a week.
First, a nor’easter blew into Boston last week, causing airlines to cancel hundreds of flights as holiday travelers tried to get home. Then snow hit the Midwest, further snarling air traffic, while icy conditions briefly closed John F. Kennedy International Airport in New York Sunday, diverting dozens of flights into Boston.
Come Monday morning, unusually warm temperatures created a thick fog that made it impossible for some planes to land in Boston. Meanwhile, with new federal regulations increasing pilot rest periods taking effect over the weekend, all the weather delays led many pilots to max out their hours, leading to even more cancellations.
