During her remarks at the 2025 Chatham House Competition Policy Conference, Deputy Assistant Attorney General Dina Kallay emphasized the significance of competition in the airline industry, particularly in light of rising travel costs affecting American families.

Kallay discussed two key cases: the Northeast Alliance between American Airlines and JetBlue, which was blocked by the DOJ due to its anticompetitive nature, and the Delta/Aeromexico joint venture, which had its antitrust immunity revoked by the Department of Transportation due to competitive concerns.

She highlighted the need for antitrust immunities to be narrowly construed and the importance of government regulations in shaping competitive dynamics in the airline sector. Kallay concluded by reaffirming the DOJ's commitment to promoting competition and addressing anticompetitive regulations that harm consumers.
