Air traffic control problems delayed flights to Florida airports by several hours, the Federal Aviation Administration told CNN. Midwinter weather is also causing significant cancellations and delays at major airports in Denver, Colorado.
Late Monday afternoon, the FAA told CNN that the matter in Florida was resolved.
“The FAA is working to safely return to normal traffic in Florida airspace,” the agency said in a statement.
Earlier in the day, the FAA told CNN that “air traffic computer problems delayed air traffic into Florida airspace.”
Publicly available Airspace Situation Notices indicated delays of about three hours on average and up to six hours early Monday afternoon.
The FAA said the problem lies with the Miami Air Traffic Control Center’s En Route Automation Modernization (ERAM) system.
That center is responsible for managing the millions of cubic miles of airspace that fly over Florida.
A spokeswoman for Miami International Airport believes the delay was caused by a Florida-wide “FAA computer system issue.”
The FAA said Monday was a busy post-Christmas travel day with 42,000 flights scheduled, and that “South-to-North volumes are likely to increase.”
According to flight tracking site FlightAware, several of Florida’s major tourist airports have been affected by problems with air traffic computers.
These include Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL), and Orlando International Airport (MCO).
New Trouble in Denver
About 750 flights departing from or to Denver International Airport were delayed or canceled Monday due to inclement weather, according to FlightAware.
According to FlightAware, as of 4:20 p.m. ET, about 285 flights scheduled to leave Denver International Airport have been delayed and about 130 flights have been cancelled. About 215 scheduled flights were delayed and over 130 were canceled.
According to CNN Weather, Denver has reported freezing fog with temperatures in the 20s since 6 a.m. local time.
Visibility was less than a quarter mile all day. It snowed lightly overnight, but the main reason for delays and cancellations is freezing fog and poor visibility.
