On Friday, thousands of travellers at U.S. airports faced delays because of an nationwide outage of U.S. Customs and Border Protection's (CBP) processing systems that lasted several hours.
"The affected systems are coming back online and travellers are being processed." CBP said in a tweet at 6:37 p.m. EDT (2237 GMT) It said there was "no indication the disruption was malicious in nature at this time." Earlier, CBP said officers were processing international travellers using alternative procedures, which caused "longer than usual wait times."
The computer issue was not impacting departures. People at various US airports posted videos on social media sites of lengthy lines at processing checkpoints and several airports warned of extensive delays. On an average day, CBP processes around 358,000 air passengers and crew.
American Airlines spokesman Ross Feinstein said the airline was "aware of the outage and are in contact with US Customs and Border Protection.The Federal Aviation Administration (FAA) said the outage had not caused any changes in flights.
