Flight Disruptions: Florida hit by air traffic control issues; Denver in Freezing Fog

(CNN) — Two far-flung states are having fresh-air travel issues on Monday.

Air traffic control problems caused hours of flight delays to Florida airports, the Federal Aviation Administration told CNN. And the main airport in Denver, Colorado, is facing significant cancellations and delays due to a crisp winter weather.

Late Monday afternoon, the FAA told CNN that the Florida issue had been resolved.

“The FAA is working to safely return to a normal traffic rate in Florida airspace,” the agency said in a statement.

Earlier in the day, the FAA told CNN that it had “slowed the volume of air traffic into Florida airspace due to an air traffic computer problem.”

A publicly available airspace status notice early Monday afternoon showed flight delays averaging almost three hours with a maximum delay of up to six hours.

The FAA said the problem is with the En Route Automation Modernization (ERAM) system at the Miami Air Route Traffic Control Center.

This center is responsible for controlling millions of cubic miles of airspace for commercial flights over Florida.

A spokesman for Miami International Airport attributed delays there to a Florida-wide “FAA computer system issue.”

The FAA previously said Monday would be a busy post-Christmas travel day with 42,000 scheduled flights, “with a potentially greater volume from south to north.”

According to flight tracking site FlightAware, some of Florida’s major airports serving tourists have been affected by the air travel computer problem.

These include Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL), and Orlando International Airport (MCO).

New trouble in Denver

About 750 flights out of Denver International Airport were either delayed or canceled on Monday due to inclement weather, FlightAware said.

As of 4:20 p.m. ET, about 285 flights scheduled to depart from Denver International were delayed and nearly 130 flights were canceled, FlightAware said. Almost 215 scheduled flights were delayed and just over 130 were cancelled.

Denver has been reporting freezing fog with temperatures in the 20s since 6 a.m. local time, according to CNN Weather.

Visibility was at or below a quarter mile all day. Light snow fell overnight, but the main reason for the delays and cancellations is the freezing fog and poor visibility.
