Court overturns DOT termination of Delta
A U.S. appeals court ruled in favor of Delta Air Lines (DAL) and Aeromexico's joint venture, allowing it to continue. The DOT had attempted to terminate the pact, focusing only on the Mexico City market. The airlines stated the joint venture enhances connectivity and competition. Data shows the partnership covers the largest U.S.-Mexico market, with Delta and Aeromexico holding nearly 20% of seats.
