DALLAS (CNN) – A telecommunications outage in Dallas is causing some travel problems.
The Federal Aviation Administration says air traffic controllers lost radar and some communications on Friday afternoon.
The FAA says the outage was due to a local telephone company equipment issue.
Hundreds of flights at Dallas-Fort Worth International and Dallas Love Field airports have been delayed.
DFW is the third-busiest airport in the world and a major hub for American Airlines, while Southwest Airlines operates a hub at Love Field.
The FAA says it’s working with the telephone company to determine the cause.
