Travelers will see fewer flights at airports around the country starting this week as the FAA cuts the number of flights to forty high-volume markets around the country starting Friday morning.

The Federal Aviation Administration said it's gearing up to cut 10% of air traffic across the country unless the government shutdown ends.With just weeks from the busy Thanksgiving holiday, people with paid flight tickets are now wondering how the reduction will impact their scheduled trips.

The names of impacted markets will be released Thursday, according to FAA Administrator Bryan Bedford. Regardless, should the reductions be realized, markets across the nation will undoubtedly be disrupted due to the ripple effects of delayed arrivals from markets dealing with reduced flights.
