Grupo Aeroméxico said a federal appeals court ruling blocked the U.S. government from terminating the its joint venture with Delta Air Lines.

The Mexican airline said Thursday that the 11th Circuit U.S. Court of Appeals in Atlanta ruled in its favor and vacated a Transportation Department order terminating approval of the joint venture, along with its antitrust immunity.

"As a result, the joint venture and its antitrust immunity remain in effect, allowing Aeromexico and Delta to continue providing enhanced connectivity, a broader network, more convenient service options and increased competition for customers traveling between Mexico and the United States," the company said.

Aeromexico also said it is reviewing the court's ruling, along with potential next steps with Delta and its legal advisers.
