• He pointed to July orders forcing Mexican airlines to file U.S. schedules for review and to the directive to unwind the Delta–Aeromexico joint venture as examples of actions Washington is prepared to take.
• U.S. airlines have challenged planned noise‑driven flight cuts at Amsterdam’s Schiphol and a passenger cap at Dublin Airport, which is currently on hold pending a legal challenge.
• JetBlue told the Transportation Department that U.S. carriers face an access problem in Lisbon and said it may seek legal remedies to secure slots.
