Atlas Air Worldwide Holdings (AAWH) has completely closed down its Florida West International Airways (Miami International) unit after the thirty-three-year-old cargo carrier's certificates of authority were all formally cancelled this week.

According to a US Department of Transportation (DOT) disclosure, FWIA surrendered its Air Carrier Certificate and Operation Specifications to the Federal Aviation Administration (FAA) earlier this month before applying to the DOT to have its certificates of public convenience and necessity cancelled.

FWIA was authorized to engage in interstate scheduled air transportation of property and mail, and foreign scheduled air transportation of property and mail between the United States and all open-skies countries. In addition, it also held all-cargo certificate authority between the United States and certain non-open-skies countries.

AAWH acquired Southern Air Holdings, Inc., for a cash consideration of approximately USD110 million in April 2016. The deal included Worldwide Air Logistics Group, Inc. and its two operating subsidiaries, Southern Air (Cincinnati International) and FWIA. Following the deal's closure, AAWH said Southern Air would be merged into AAWH's Atlas Air (5Y, New York JFK) unit leaving FWIA to be wound down.

The ch-aviation aircraft database shows that over its lifetime, FWIA operated seven B707-300s, one B727-200, and one B767-300(F). Prior to it ceasing all operations on February 28, 2017, FWIA had shared B767-300F aircraft with LATAM Cargo Chile (UC, Santiago de Chile).
