Delta Air Lines and its partner Aeromexico have reportedly taken legal action to prevent the dissolution of their joint cooperation agreement. The airlines have asked a court to block a government order that would force them to end their partnership. This move signals the carriers' intent to fight to preserve their strategic alliance, which allows them to coordinate flights and fares between the United States and Mexico. The termination of this joint venture could have significant implications for both airlines' trans-border operations, potentially affecting route networks and market share. Details regarding the specific court or the timeline for a decision were not immediately available. The legal challenge introduces a period of uncertainty for the future of the partnership, and the outcome will be closely watched by the aviation industry. No market reaction was available.
