The FAA is slashing flights because of the shutdown. Here's what travelers can expect

Travelers can expect to see fewer flights to many major U.S. cities starting Friday morning, when the Federal Aviation Administration said it would reduce traffic across 40 airports to ease the load on the nation's air traffic controllers.

The head of the FAA said the move was unprecedented but necessary to keep air travel safe as traffic controllers, who are federal employees, show increasing signs of stress and fatigue while working unpaid during the longest government shutdown on record.
