Gibson Dunn achieved a major litigation victory at the Eleventh Circuit Court of Appeals on behalf of client Delta Air Lines, Inc., and its partner Aeromexico.

For nearly a decade, Delta and Aeromexico have operated a joint venture approved by the U.S. Department of Transportation (DOT), allowing them to fully integrate their operations on flights between the U.S. and Mexico.  In September, the DOT terminated its approval of the joint venture effective January 1, 2026. Delta challenged the DOT’s action in the U.S. Court of Appeals for the Eleventh Circuit and sought a stay to avert the severe irreparable harm Delta and Aeromexico would experience if forced to unwind their joint venture. On November 12, the Eleventh Circuit granted a stay of the DOT’s order pending resolution of the litigation.

The Gibson Dunn team representing Delta includes partners Eugene Scalia and Amir Tayrani, of counsel Christine Buzzard, and associates Michael Corcoran, Lavi Ben Dor, and Tamara Skinner.
