At least 800 flights were canceled Friday at 40 airports across the U.S. as the FAA slashed routes as a result of the government shutdown, according to flight tracking website FlightAware.
Why it matters: With the Thanksgiving travel rush weeks away, the cuts will hit some of the busiest airports in the U.S. — including Hartsfield-Jackson Atlanta International and Dallas Fort Worth International.
A 4% "reduction in operations" took effect Friday, "ramping up" to 6% by Tuesday, 8% by Nov. 13 and 10% by Nov. 14, per a Thursday evening emailed statement from Transportation Secretary Sean Duffy and Federal Aviation Administration Administrator Bryan Bedford.
Catch up quick: Duffy has warned of "mass chaos" stemming from staffing shortages as critical air travel staff feels the strain of missed paychecks.
"This is going to lead to more cancellations," Duffy said during Wednesday's briefing.
