“The Federal Aviation Administration ordered a 10% reduction in flight capacity at the busiest airports in the U.S., including Miami International Airport,” Levine Cava confirmed in a statement. “This decision could have significant repercussions for our region’s economy, connectivity and workforce.”

The Federal Aviation Administration is forcing airlines to cut 10% of their flights at 40 of the busiest airports — including Miami and Fort Lauderdale — across the nation to reduce pressure on air traffic controllers during the ongoing government shutdown and ensure that flying remains safe.

Frontier expects its flights to operate as planned. Customers whose flights are canceled or are delayed by more than three hours (domestic flights) or six hours (international flights) may rebook or request a refund.

Some of the nation's busiest airports could see flight cuts starting on Friday if the government shutdown continues.

The Federal Aviation Administration has issued temporary flight restrictions in Miami on Wednesday due to President Trump's scheduled appearance at a conference.

Millions of Americans expecting to fly this month could have their plans grounded if the government shutdown drags on.
